Patent 4,575,330 (Apparatus for Production of Three-Dimensional Objects by Stereolithography) a b Gibson, Ian, and Jorge Bártolo, Paulo.
12 With the help of computer aided manufacturing or computer-aided design (CAM/CAD) software, 13 the UV laser is used to draw a pre-programmed design or shape on to the surface of the photopolymer vat.
Schematic representation of Stereolithography: a light-emitting device a) (a laser or, dLP ) selectively illuminates the transparent bottom c) of a tank b) filled with a liquid photo-polymerizing resin.

In the absence of cold hard facts, we can indulge in some warm squishy speculation and educated guesswork.21 Advantages and disadvantages edit Advantages edit One of the advantages of stereolithography is its speed; functional parts can be manufactured within a day.Archived from the original on 14 February 2008.24 Businesses can use those prototypes to assess the design of their product or as publicity for the final product."Photopolymerization Reactions." The Wiley Database of Polymer Properties 3 (2003.The UV laser then writes the bottom-most layer of the desired part through the transparent vat bottom.
The beam is focused onto the surface of the liquid photopolymer, creating each layer of the desired 3D object by means of crosslinking (generation of intermolecular bonds in polymers).
There are potential errors possible when making medical models using stereolithography but these can be avoided with practice and well trained operators.

3 This process is repeated for each layer of the design until the 3D object is complete.
This approach is typical of desktop SLA printers, video intro maker for youtube while the right-side-up approach is more common in industrial systems.Retrieved m sr8-3 keywords3dresin.Crivello, James., and Elsa Reichmanis."With tupperware croissant maker lasers and hot nylon, Formlabs just took 3D printing to a whole new level".In the background of the teaser image for this announcement, we see a blurred 3D printer in signature LulzBot black color.Introduction to Rapid Prototyping and Manufacturing.LulzBot already competes effectively for this prosumer dollar with its Taz 6 and Mini 2 3D printers, so it only makes sense for it to offer a high-resolution alternative to the individuals and companies it has already convinced with its FDM offerings.
