Stereolithography resin resembles white ABS.A new, tough material for stereolithography The first 3D printing technology, which was pioneered by Chuck Hull of 3D Systems. See 3D printing. rapid prototyping Building a part one layer at a time using a method of additive fabrication such as 3D printing. Such parts are used for concept modeling to determine if the product design meets the customer's expectations. and manufacturing is said to simulate the look and feel of molded ABS. Accura 55 Plastic is the latest addition to a family of photocurable epoxies from 3D Systems Corp., Rock Hill, S.C. It is designed to work on all SLA (1) (StereoLithography Apparatus) See 3D printing. (2) (Service Level Agreement) A contract between the provider and the user that specifies the level of service expected during its term. systems. It is suited to prototyping, rapid manufacturing, and functional testing of auto interior parts, electronic components, and master patterns for urethane urethane (yoor´ithān´), n ethyl carbamate used as an anesthetic agent for laboratory animals, formerly used as a hypnotic in humans. casting. Recently tested by medical-device makers Boston Scientific in Natick, Mass., and Harvest Technologies Corp., Plymouth, Mass., Accura 55 was praised for its high productivity and part quality. Says Boston Scientific's rapid-prototyping team leader Joseph Cihlar, "Its speed has allowed us to produce more models in a shorter time. In addition, our engineers are amazed that they cannot distinguish the Accura 55 prototypes from machined ABS and acetal acetal /ac·e·tal/ (as´e-t'l) 1. any of a class of organic compounds formed by combination of an aldehyde molecule and two alcohol molecules. 2. articles." Jason Morgan, Harvest's stereolithography production manager says the material's low viscosity allowed the firm to clean and finish parts more easily. He also cites a high build success rate, and higher quality parts with mechanical properties that allow models to serve as functional prototypes.
