A company in Japan called Unirapid Inc. developed a small SLA 3D printer which they claim has the same printing accuracy/quality as the high end industrial 3D printers. The printer is called the Unirapid 3 and works with the stereolithography printing technology.
The stereolithography technology makes it possible for the printers to build models with a minimum layer thickness of 0.05mm. The build envelope is 150x150x150mm. The resin material that can be used is ProtoGen 18420, this is a liquid ABS-like, photopolymer that produces accurate parts.
This printer, the Unirapid 3, is not recommended for large prints. The print speed of the Unirapid 3 is slow because of the high detail it can give. So if you want o make high resolution parts for research and development of whatever, this is your printer!
