Analysis of electronic structures of physostigmine analogs. (1/779)

AIM: To elucidate the action mechanism and structural prerequisites of 21 physostigmine analogs as acetylcholinesterase inhibitors at the molecular level, and help the rational design of these dihydroindoline inhibitors. METHODS: Initial structures of these compounds were built and minimized by SYBYL 6.2 molecular modeling software. Conformations of those molecules with the highest predictive abilities in the Comparative Molecular Field Analysis model were chosen to the semiempirical quantum chemical calculations. RESULTS: (1) The highest occupied molecular orbital (HOMO) consisted mainly of the orbitals in phenyl group and N1 atom; the lowest unoccupied molecular orbital (LUMO) of the molecules was contributed from phenyl group and C11 atom. While the HOMO energies did not show any recognizable relationship with activity, the LUMO energies showed a decreased tendency with increasing activity. The active compounds showed lower LUMO energies. (2) The carbon atom (C11) had the most positive net atom charge. The most active compound had the most positive charge on this carbon, but had the lower charges on the carbonyl oxygen (O12) which was the most negative charge atom. (3) The bond order of carbon-oxygen bond (C11-O10) was invariant across the series of the compounds. (4) Compounds with too high or too low total dipole moment had lower activities, while the most active one had a lower molecular polarizability. CONCLUSION: A molecular model was suggested to explain the possible mode of action by which these compounds inhibit acetylcholinesterase.  (+info)

A 3D computer-aided design system applied to diagnosis and treatment planning in orthodontics and orthognathic surgery. (2/779)

The purpose of this article is to describe a newly developed 3D computer-aided design (CAD) system for the diagnostic set-up of casts in orthodontic diagnosis and treatment planning, and its preliminary clinical applications. The system comprises a measuring unit which obtains 3D information from the dental model using laser scanning, and a personal computer to generate the 3D graphics. When measuring the 3D shape of the model, to minimize blind sectors, the model is scanned from two different directions with the slit-ray laser beam by rotating the mounting angle of the model on the measuring device. For computed simulation of tooth movement, the representative planes, defined by the anatomical reference points, are formed for each individual tooth and are arranged along a guideline descriptive of the individual arch form. Subsequently, the 3D shape is imparted to each of the teeth arranged on the representative plane to form an arrangement of the 3D profile. When necessary, orthognathic surgery can be simulated by moving the mandibular dental arch three-dimensionally to establish the optimum occlusal relationship. Compared with hand-made set-up models, the computed diagnostic cast has advantages such as high-speed processing and quantitative evaluation on the amount of 3D movement of the individual tooth relative to the craniofacial plane. Trial clinical applications demonstrated that the use of this system facilitated the otherwise complicated and time-consuming mock surgery for treatment planning in orthognathic surgery.  (+info)

Targeting the HIV-protease in AIDS therapy: a current clinical perspective. (3/779)

This review deals with clinical applications of compounds that inhibit the action of the protease encoded within the genome of human immunodeficiency virus (HIV). The HIV-protease is essential for viral maturation and represents an important therapeutic target in the fight against AIDS. Following a brief overview of the enzyme structure and function, the article focuses on a number of peptide and non-peptide based HIV-protease inhibitors that are in current clinical use. These drugs are discussed both with respect to their efficacy in treatment of AIDS, and to problems related to insurgence of viral resistance and side effects seen to date in patient populations.  (+info)

Effect of polishing on cyclic fatigue strength of CAD/CAM ceramics. (4/779)

The biaxial flexural strength and cyclic fatigue biaxial flexural strength of CAD/CAM ceramics polished with #220, 400, 600 and 1000 diamond pads were measured in an effort to determine the effect of surface roughness on fatigue behavior of dental ceramics. The surface roughness was improved after polishing with a smaller diamond grain pad. The flexural strengths of the specimens polished with #220, 400, 600 and 1000 diamond pad were 75.2, 76.6, 82.2, and 83.3 MPa, respectively; the fatigue flexural strength of those with #220, 400, 600 and 1000 were 53.0, 58.1, 60.0, and 61.5 MPa, respectively. Both the flexural and fatigue flexural strengths increased with improvement of surface profile. These results suggest the importance of polishing of dental ceramics for not only the static strength but also the cyclic fatigue strength.  (+info)

Influence of filler content and gap dimension on wear resistance of resin composite luting cements around a CAD/CAM ceramic inlay restoration. (5/779)

We investigated the influence of filler content and gap dimension on the wear resistance of composite luting cement around CAD/CAM ceramic inlay restorations. Experimental hybrid dual-cured composite luting cements containing 60, 70, 72, 74 and 80 wt% of silanated barium-silica fillers were used for cementing CAD/CAM ceramic inlay into the cavity. The specimens involving inlay-cement-tooth interfaces were subjected to a three-body wear test. The relation between the interfacial gap dimension and wear loss was also investigated using 60, 70 and 80 wt% filled cements. The cements containing more than 70 wt% filler presented significantly higher wear resistance than 60 wt% filled cement. There was a positive linear relationship between gap dimension and wear loss, and the inclination of the regression line decreased with increasing filler content. These results indicated that the higher filler content of the cement increased the wear resistance and this desirable influence appeared more remarkably in the wider horizontal gap dimension.  (+info)

The Procera abutment--the fifth generation abutment for dental implants. (6/779)

The Branemark dental implant has undergone progressive development in terms of both the implant body itself and the components connecting the implant to the prosthesis. Many screw and abutment designs have been developed, with various degrees of success. About 15 years ago, CAD (computer-assisted design)-CAM (computer-assisted manufacture) technology was introduced to dentists. More recently CAD-CAM has been used in the manufacture of abutments for implants. This article reviews currently available techniques for creating the Procera custom abutment (Nobel Biocare, Goteborg, Sweden) and outlines appropriate applications for this type of implant.  (+info)

Application of secondary structure prediction in antisense drug design targeting protein kinase C-alpha mRNA and QSAR analysis. (8/779)

AIM: To optimize the design of antisense drug targeting protein kinase C-alpha (PKC-alpha) mRNA and obtain better antisense drugs than ISIS3521 that is undergoing clinical trials. METHODS: RNAstructure (version 3.21, 1999) was utilized to predict the optimal and suboptimal secondary structures of human PKC alpha mRNA (GenBank, X52479), and 29 antisense phosphorothioate oligodeoxynucleotides (S-ODN) targeting the secondary structural elements, 3 partly matched S-ODN and 1 scrambled 3521 were designed. ISIS3521 was set as positive control. Mean (n = 3-5) 50% inhibitory effects on proliferation of A549 cells (IC50) of S-ODN were evaluated. Free energies (delta G degree 37) relating to the target secondary structural elements were calculated according to the nearest neighbor model. The quantitative structure-activity relationship (QSAR) analysis through multiple regression was obtained by SPSS. RESULTS: Three S-ODN; (5'-AGCCCA-GCCGCTTGGCTGGG-3', 5'-AGGAGTGCAGCTGC-GTCAAG-3', 5'-TCAGAGGG-ACTGATGACTTT-3') had lower IC50[(48 +/- 7), (50 +/- 4), (64 +/- 2.7) nmol.L-1, respectively] than that of ISIS3521 [(81 +/- 25) nmol.L-1]. The number of bases comprising the target secondary structural element bulge loop, internal loop, and knot, the free energy of S-ODN (delta G degree 37S), and reaction (delta G degree 37R) were important parameters in QSAR equation. In the multiple regression, R was 0.68, P = 0.0193. Not tally with the equation, two S-ODN (5'-TCAAATGGAGG-CTGCCCGGC-3', 5'-AAAACGTCAGCCATGGTCCC-3') with favorable target structures and delta G degree 37 did not behave good activities. CONCLUSION: Computer aided design was helpful to obtain S-ODN with better in vitro effect than current positive drug. The degree of instability of secondary structural elements and delta G degree 37 were important factors for drug activity. Other important factors needed for further investigation.  (+info)

In todays global and digital world, computer-aided design (CAD) can facilitate communication among design team members and make engineers more efficient. To meet the needs of the modern design team it is important that CAD models be formulated in a manner that is easily understood and that they can easily be altered. This work examines the role of an incentive to produce models quickly on feature selection, order, and organization (design intent). The role of design intent on model perception and the time required to alter a model is also investigated. The incentive to produce designs quickly is shown to have a negative effect on model attributes associated with proper design intent. Feature selection and organization are shown to affect model perception. The overall rating of a model is shown to be correlated with the time required to alter it. The importance of design intent on the perception of, and alteration time for, CAD models is shown.. Copyright © 2009 by ASME ...
Detection of chemical signals is critical for cells in nature as well as in synthetic biology, where they serve as inputs for designer circuits. Important progress has been made in the design of signal processing circuits triggering complex biological behaviors, but the range of small molecules recognized by sensors as inputs is limited. The ability to detect new molecules will increase the number of synthetic biology applications, but direct engineering of tailor-made sensors takes time.. Here we describe a way to immediately expand the range of biologically detectable molecules by systematically designing metabolic pathways that transform nondetectable molecules into molecules for which sensors already exist. We leveraged computer-aided design to predict such sensing-enabling metabolic pathways, and we built several new whole-cell biosensors for molecules such as cocaine, parathion, hippuric acid, and nitroglycerin..

This paper presents a computer-aided design (CAD) module able to analyze different manufacturing configurations of tubes used in mechanical assemblies, such as exhaust system manifolds. It can be included in the knowledge-based expert system category and has been implemented into a CAD platform as a dedicated module able to take into account manufacturing requirements related to tube bending, hydroforming, and cutting. The experts knowledge, in terms of set of rules and criteria, has been implemented by means of the automation tools of CATIAV5R10 according to the so-called methodological formal approach. The resulting module is able to join different tubes starting from their geometrical models, obtaining a set of manufacturing alternatives. Each of them is verified with respect to collisions with a bending machine and also in terms of hydroforming process feasibility. Only those solutions that satisfy these checks are accepted as feasible and ranked according to three evaluation criteria ...
ARCADES aims at disrupting the traditional paradigm in Computer-Aided Design (CAD) by exploiting cutting-edge research in mathematics and algorithm design. Geometry is now a critical tool in a large number of key applications; somewhat surprisingly, however, several approaches of the CAD industry are outdated, and 3D geometry processing is becoming increasingly the weak link. This is alarming in sectors where CAD faces new challenges arising from fast point acquisition, big data, and mobile computing, but also in robotics, simulation, animation, fabrication and manufacturing where CAD strives to address crucial societal and market needs. The challenge taken up by ARCADES is to invert the trend of CAD industry lagging behind mathematical breakthroughs and to build the next generation of CAD software based on strong foundations from algebraic geometry, differential geometry, scientific computing, and algorithm design. Our game-changing methods lead to real-time modelers for architectural geometry ...

Computer-aided design (CAD) of sporting equipment requires knowledge of the mechanical properties of proposed materials. The mechanical properties of composite materials are often not as simple to obtain as those of conventional materials, in which case micro-mechanical modelling could be used in conjunction with CAD software. A micro-mechanical model was used to predict the flexural modulus of composite materials, based on the assumption of partial interfacial adhesion between composite components. It was found that the partial adhesion model was both practical and consistently accurate. The partial adhesion model accounted for adhesion between components by considering an effective shear value at the interface. The model was compared to experimental data for glass, wood and carbon-fibre reinforced polyethylene. It was shown that the adhesion coefficient ranged between 0.1 for carbon fibre, 0.5 for glass fibre and 0.8 for the wood fibre composites. It was shown that using micro-mechanical ...

The engineering of catalysts with desirable properties can be accelerated by computer-aided design. To achieve this aim, features of molecular catalysts can be condensed into numerical descriptors that can then be used to correlate reactivity and structure. Based on such descriptors, we have introduced topographic steric maps that provide a three-dimensional image of the catalytic pocket-the region of the catalyst where the substrate binds and reacts-enabling it to be visualized and also reshaped by changing various parameters. These topographic steric maps, especially when used in conjunction with density functional theory calculations, enable catalyst structural modifications to be explored quickly, making the online design of new catalysts accessible to the wide chemical community. In this Perspective, we discuss the application of topographic steric maps either to rationalize the behaviour of known catalysts-from synthetic molecular species to metalloenzymes-or to design improved catalysts ...

This thesis presents a new computer-aided linkage design and simulation system for task driven path generation problem. Mechanism design is considered a mixture of science and art. The former is about utilizing computers to rigorously sizing a mechanism in meeting a set of design requirements. And the latter is about taking advantage of designers experience to narrow down design domain and speed up the design process. The ultimate goal of the presented design system is to incorporate both science and art into the linkage design process by (1) developing an automatic design framework based on library searching and optimization techniques and (2) developing an interactive design framework based on advanced human-computer interfaces. To enable the design automation framework, we first built a library of open and closed planar curves generated by commonly used planar linkages. We then turned the classical linkage path generation problem into a library searching problem together with a local ...
Computer-aided building design (CABD) has been very diversified since the design process encompasses so many decision making steps by architects. However, the segregated design decision making process frequently prevents achievement of effective evaluation of a buildings final performance. Thus, integration of isolated design decision support systems into a CABD system is a crucial step toward responsible design. To enhance energy performance of a building at the design stage, a rigorous energy simulation process has to be adopted into an integrated CABD system. A prototype interface system is developed for a building energy simulation model illustrating appropriate input processing and results analysis & recovery system paradigm in an integrated CABD environment. In the prototype (ENERife), utilization of normalized building descriptions for 15 building types enable building designers (1) to configure a complicated building description dynamically at the preliminary design stage and, (2) to ...

The role of structural activities and other solution searching activities in design learning and problem solving have been identified in laboratory studies of problem solving and also in case studies of design teaching.. In laboratory studies, students have solved creative problems collaboratively under various communication conditions. The case studies follow students working on the same problem under two conditions one group is taught using traditional face-to-face teaching while the other group is additionally supported by a textbased web board. This paper review findings from three experiments from which we can see that students producing above average solutions involved more structural activities than the mediocre cases. These successful cases engaged in textual expression of their design solutions. Computer tools for design should therefore support multiple representations of design work ...

Mandibular sagittal split osteotomy (SSO) is an operation performed for the correction of mandibular deformities. In this operation, sharp rotary tools are used during osteotomies and this can induce some complications. For example, if the inferior alveolar nerve is damaged, paralysis of the teeth, the lateral side of the tongue, and the corner of the lip can occur. To decrease the occurrence of such possible complications, we designed and manufactured a novel computer-assisted, patient-specific SSO guide and soft tissue retractor in our previous study. And, we first tested this apparatus on a cadaveric bone in vitro. Now, in this study, a surgical application of the instrument, which was designed and manufactured according to the requirements of the mandibular sagittal split osteotomies, was performed. This paper gives and discusses the results obtained from in vivo application of the apparatus.. ...
Genetically-encoded biosensors offer a wide range of opportunities to develop advanced synthetic biology applications. Circuits with the ability of detecting and quantifying intracellular amounts of a compound of interest are central to whole-cell biosensors design for medical and environmental applications, and they also constitute essential parts for the selection and regulation of high-producer strains in metabolic engineering. However, the number of compounds that can be detected through natural mechanisms, like inducible transcription factors, is limited; expanding the set of detectable compounds is therefore highly desirable.. Here, we present the SensiPath webserver, accessible at http://sensipath.micalis.fr.. SensiPath implements a strategy to enlarge the set of detectable compounds by screening for multi-step enzymatic transformations converting non-detectable compounds into detectable ones. The SensiPath approach is based on the encoding of reactions through signature descriptors to ...

Mucosal seal formation around dental abutments is critical to the successful integration of dental implants into the human oral cavity. No information exists for how clinically relevant polishing procedures for computer-aided design and computer-aided manufactured (CAD/CAM) zirconia abutments affects cellular responses important to mucosal seal formation. CAD/CAM zirconia was divided into four groups for clinically relevant polishing utilizing commercial polishing heads: control, coarse, coarse plus medium, and coarse plus medium plus fine. Surfaces were analyzed with scanning electron microscopy (SEM), atomic force microscopy (AFM), and optical profilometry (OP). Subsequently, human gingival fibroblasts (HGFs) were seeded onto the zirconia surfaces. Proliferation was measured via a quantitative SEM technique and focal adhesion kinase (FAK) phosphorylation status was measured by an enzyme-linked immunosorbent assay (ELISA). Results showed an increase in proliferation on all polished surfaces as compared
The simulator was developed based on the neuroimaging (axial noncontrast CT and T1-weighted gadolinium-enhanced MRI) of an 8-year-old patient with a colloid cyst and hydrocephalus. Image segmentation, computer-aided design, rapid prototyping (3D printing), and silicone molding techniques were used to produce models of the skull, brain, ventricles, and colloid cyst. The cyst was filled with a viscous fluid and secured to the roof of the third ventricle. The choroid plexus and intraventricular veins were also included. Twenty-four neurosurgical trainees performed a simulated colloid cyst resection using a 30° angled endoscope, neuroendoscopic instruments, and image guidance. Using a 19-item feedback survey (5-point Likert scales), participants evaluated the simulator across 5 domains: anatomy, instrument handling, procedural content, perceived realism, and confidence and comfort level.. ...

Y1 - 2013/7/1. N2 - Presently, commercially available porous bone substitutes are manufactured by the sacrificial template method, direct foaming method, and polymer replication method (PRM). However, current manufacturing methods provide only the simplest form of the bone scaffold and cannot easily control pore size. Recent developments in medical imaging technology, computer-aided design, and solid freeform fabrication (SFF), have made it possible to accurately produce porous synthetic bone scaffolds to fit the defected bone shape. Porous scaffolds were fabricated by SFF and PRM for a comparison of ...
Report Outline: 3D printing is a type of printing technique that is capable of manufacturing 3D solid objects based on a digital file that is created using computer assisted design. The final solid object is created using additive processes by laying down successive layers of materials till completion. Each layer is considered to be a thinly sliced horizontal cross-section of the eventual product or object. 3D printing is a type of manufacturing used to build layers to form a solid 3D object based on a digital model. The technology uses computer-aided design to make the digital model. The digital model is dissected into multiple cross-sections known as layers. The printer starts at the bottom and builds up from there, layer by layer until the entire design is complete to give the desired object. ...
Desktop Metal and Markforged were inspired by a different manufacturing method called metal injection molding. In this system, the metal powder is mixed with plastic binders. The mixture is heated and injected into molds that form it into complex shapes. The part is then baked in high-temperature ovens that burn off the plastic material and turn the object into solid metal.. Metal 3-D printing takes the same general approach, but without the expensive molds. Instead, engineers can design a complex part using standard computer-aided design programs from companies like Autodesk. The digital file goes straight to the printer.. The Desktop Metal and Markforged machines squirt the metal powder and binder through tiny nozzles. Each object is built up layer by layer, hour by hour. When the print job is done, the object is placed in the same kind of oven used in metal injection molding, producing solid metal parts.. Ironically, Desktop Metals printers are partly made out of injection-molded plastic. ...
Dmitry Grishin was born on a missile base in the Soviet Union. He grew up around technical people working on secret projects; his father designed radar systems for the MiG-29 jet fighter.. In Russia, every boy wanted to be a spaceman. But Grishin was taken by robotics. He remembers seeing his first Western VCR when he was about 12 and being fascinated by the mechanical movement that drew the tape into the player. There were Russian robots to admire as well, like Lunokhod 2, a remote-controlled lander that had set down on the moon in 1973. That you can sit on Earth and drive the device-I thought it was so cool, he says.. Then came the end of the Soviet Union and the tarnishing of its glories. Grishin left home for Moscow State Technical University with a few rubles. But he had a knack for programming and for managing others. By the time he was 20, he was overseeing programmers in Florida for a computer-aided design company from his student hostel in Moscow.. Those were the early days of the ...

Published on: November 7, 2012. by Science Blog:. Researchers at Dalhousie University have discovered a new technique using computer-aided drug design that may lead to an entirely new approach in the treatment of Alzheimers disease (AD).. Alzheimers is a devastating disease for which no truly disease-modifying drugs are available. Our approach is completely novel. We explore how the human body attempts to protect itself from Alzheimers, and then we exploit this to develop an entirely new approach to therapeutics, explained Dr. Weaver, a professor at Dalhousie University, clinical neurologist at Capital Health and IWK Health Centre, Canada Research Chair in Clinical Neuroscience, and the DMRF Irene MacDonald Sobey Chair in Curative Approaches to Alzheimers Disease. We are extremely excited about the results presented in this paper and believe that this may represent a new approach to the treatment of AD.. Weaver says that he and his fellow researchers have successfully identified ...

One of the most recent innovations in bone augmentation surgery is represented by computer-aided-design/computer-aided-manufacturing (CAD/CAM) customized titanium meshes, which can be used to restore vertical bone defects before implant-prosthetic rehabilitations. The aim of this study was to evaluate the effectiveness/reliability of this technique in a consecutive series of cases. Ten patients in need of bone augmentation before implant therapy were treated using CAD/CAM customized titanium meshes. A digital workflow was adopted to design virtual meshes on 3D bone models. Then, Direct Metal Laser Sintering (DMLS) technology was used to produce the titanium meshes, and vertical ridge augmentation was performed according to an established surgical protocol. Surgical complications, healing complications, vertical bone gain (VBG), planned bone volume (PBV), lacking bone volume (LBV), regenerated bone volume (RBV), average regeneration rate (RR) and implant success rate were evaluated. All augmented sites

Documenting the indication on prescriptions and dispensed medicines labels is not standard practice in Australia. However, previous studies that have focused on the content and design of dispensed medicines labels, have suggested including the indication as a safety measure. The aim of this study was to investigate the perspectives of Australian consumers, pharmacists and prescribers on documenting the indication on prescriptions and dispensed medicines labels. Semi-structured interviews were conducted and mock-up of dispensed medicines labels were designed for participants. Consumers (n = 19) and pharmacists (n = 7) were recruited by convenience sample at community pharmacies in Sydney (Australia) and prescribers (n = 8), including two medical students, were recruited through snowballing. Thirty-four participants were interviewed. Most participants agreed that documenting the indication would be beneficial especially for patients who are forgetful or take multiple medications. Participants also
An interposer including a fence that receives and aligns a semiconductor device, such as a flip-chip type semiconductor device, with a substrate. The fence may include edges that are configured to progressively align a semiconductor device with the substrate. The fence may also include one or more laterally recessed regions to facilitate rough alignment of a semiconductor device with the substrate. Methods for fabricating the fence include the use of stereolithographic and molding processes. When stereolithography is used to fabricate the fence, a machine vision system that includes at least one camera operably associated with a computer may be used to control a stereolithography apparatus and facilitates recognition of the position and orientation of substrates on and around which material is to be applied in one or more layers to form the fence. As a result, the substrates need not be precisely mechanically aligned.
Chitosan-g-oligolactide copolymers with relatively long oligolactide grafted chains of various stereochemical compositions have been synthetized via a solvent-free mechanochemical technique and tailored to fabricate three-dimensional hydrogels using two-photon induced microstereolithography. An effect of the characteristics of chitosan and oligolactide used for the synthesis on the grafting yield and copolymers behavior were evaluated using fractional analysis, FTIR-spectroscopy, dynamic light scattering, and UV-spectrophotometry. The lowest copolymer yield was found for the system based on chitosan with higher molecular weight, while the samples consisting of low-molecular weight chitosan showed higher grafting degrees, which were comparable in both the cases of l,l- or l,d-oligolactide grafting. The copolymer processability in the course of two-photon stereolithography was evaluated as a function of the copolymers characteristics and stereolithography conditions. The structure and mechanical

CAD/CAM has improved the quality of prostheses in dentistry and found a way to standardise the production process. It has increased productivity and the chance to work with new materials with a high level of accuracy.[5] It has also found a way to decrease chair time for the patient by the use of CEREC systems which allow the dentist to send electronic impressions to the lab.[12] The restorations are milled from a block of ceramic which has fewer flaws.[13]. However, CAD/CAM requires a large initial outlay (expensive to buy) and occlusal detail isnt always the best and has to be amended by hand.[13]. Despite the CAD/CAM being a major technological advancement, it is important that the dentists technique is suited to the methods of CAD/CAM and milling technology. This includes: correct tooth preparations with a continuous preparation margin (which is recognisable to the scanner e.g. in the form of a chamfer); avoiding the use of shoulderless preparations and parallel walls and the use of ...
Since implementing the rapid-tooling process, the company has doubled its revenues while gaining speed and efficiency advantages using direct metal laser-sintering with cryogenic processing compared with conventional CNC milling of aluminum molds. CPM Fastools process uses EOS DMLS technology to produce fully dense metal-core and cavity inserts. The inserts, and all mold components, are cryogenically processed to relieve residual stress and increase wear resistance. The company says its production molds are ideal for resins that are difficult to injection-mold and cause rapid tooling wear. We have made production tools for molding tough resins like polyphenylsulfone and glass-filled engineering plastics, adds Moore.. More traditional prototyping processes using plastics for rapid prototyping purposes include FDM, stereolithography, and 3-D printing, methods which continue to account for the majority of prototypes built for industry.

Charles W. Hull is a name you might not be familiar with, but he is the man behind the worlds first patented 3-D printer. Invented in 1984, Hulls printer used a technique called stereolithography, which employs a UV laser that solidifies a photopolymer into a 3-dimentional shape outlined in a computer-aided-design (CAD) file. This invention closely followed the work of Hideo Kodama of Nagoya Municipal Industrial Research Institute, who in 1981 was the first person to use a light-sensitive resin to build a miniature three-dimensional model of a house. Hull went on to found 3-D Systems, which remains the worlds second-largest manufacturer of 3-D printers, next to Stratasys.. 3-D printers boast rapid prototyping technology, which means concepts are able to be quickly and efficiently turned into three-dimensional models, allowing for optimization of computer-generated designs. This technology also benefits manufacturers, who have the option to build their products on an order-by-order basis, with ...
But while both may be referred to as 3D printing theres a world of difference between the two processes, and theyre not the only ways of creating real objects from a three-dimensional computer model. So, just what is 3D printing?. Its something of a catch-all term, used to describe some very different technologies, and encompassing things like stereolithography, rapid prototyping and additive manufacturing. But at heart, what the name conjures up is the image of a device that, once fed the right instructions, can churn out any object that you want, from shoes to aircraft parts.. In reality, thats still some way off. While there are some machines that can use two print heads to lay down, for instance, conductive tracks as well as polymers, creating objects that use several materials, or that emerge as fully formed machines rather than components is some way off.. How does 3D printing work? The phrase additive manufacturing gives the best clue: objects are built up layer by layer, based ...
A rapid prototyping and manufacturing (e.g. stereolithography) method and apparatus for producing three-dimensional objects by selectively subjecting a liquid or other fluid-like material to a beam of prescribed stimulation. In a preferred embodiment a source of prescribed stimulation is controlled to reduce or inhibit the production of the prescribed stimulation during at least some periods when the prescribed stimulation is not needed to expose the material. In another preferred embodiment, the source of stimulation is controlled to vary the quantity of prescribed stimulation that is produced and allowed to reach the material. In an additional preferred embodiment control of laser output occurs based on a combination of supplying a regulated amount of voltage to an AOM in conjunction with temporary sensing of laser power and a known desired power to attain. In a further preferred embodiment, a quantity of prescribed stimulation may be set by consideration of desired solidification depths to be used,

If you are like me and have no real background in engineering or chemistry, keeping the different 3D printing technologies straight may sound daunting. In this post, I will attempt to give a simplified overview of the seven major types of 3D printing technologies and summarize the key advantages and disadvantages for each. I hope this information helps anyone who is interested in acquiring a 3D printer understand the different processes better and direct you to a specific technology that suits your needs the best. 3D printing is an additive process that creates volume by adding material one layer at a time following a predetermined pattern as opposed to milling, where material is removed from a raw block. The American Society for Testing Materials (ATSM) has defined seven major additive manufacturing processes, each represented by one or more commercial technologies. 1) Vat photopolymerization (Stereolithography, SLA) Invented over 30 years ago, SLA is the foundational technology of 3D printing. ...
The present invention provides a method for producing an ophthalmic device by means of stereolithography. The method comprises the steps of: depositing (i) an essentially solvent-free liquid or melt of a device-forming material, or (ii) a solution of said device-forming material, into a container wherein said device-forming material is crosslinkable or polymerizable by actinic radiation; irradiating said device forming material with one or more activation energy beams to obtain a cured layer of polymerized or crosslinked device-forming material; irradiating said device-forming material with said one or more activation energy beams to obtain a cured layer on top of a previously cured layer; and repeating step (c) to obtain additional cured layers until said ophthalmic device is created integrally, wherein each of cured layers corresponds to a pertinent slice of said ophthalmic device.
In addition to the Leadership in Engineering 2010 award, 2011 will mark an important milestone for 3D Systems, the 25th anniversary of the invention of Stereolithography (SLA) by founder, Chuck Hull.
Principle of Continuous Liquid Interface Production technology (CLIP), Image Credit: Carbon3D. In what may be one of the biggest stories we have covered this year, a new company, Carbon3D has just emerged out of stealth mode, unveiling an entirely new breakthrough 3D printing process, which is anywhere between 25 and 100 times faster than whats available on the market today.The privately-held Redwood City, California-based company, Carbon3D, was founded in 2013, and since then has been secretly perfecting a new 3D printing technology which promises to change the industry forever. The technology that the company calls Continuous Liquid Interface Production technology (CLIP) works by harnessing the power of light and oxygen to cure a photosensitive resin. Sounds an awful lot like Stereolithography (SLA) technology, doesnt it? While it uses principles we see within a typical SLA process, where a laser or projector cures a photosensitive resin, Carbon3Ds CLIP process strays greatly from the ...
