Apparatus for High Temperature Stereolithography

Description:

Stereolithography (SLA) has traditionally been limited to low viscosity resins that flow easily at room temperature. These constraints greatly limit the molecular weights and polymeric classes of the oligomeric components that can be used. Many of the strongest and highest glass-transition temperature (Tg) engineering polymers fall into this category of materials that cannot be processed using SLA. Through the use of novel processing techniques (coupled with novel approaches to polymer chemistry), these materials can be fabricated into end-use parts without the need for extensive post-processing. Chemical and flame resistant, high strength, and very high Tg polymers can be rapidly fabricated at low cost for myriad applications in the aerospace, automotive, medical industries.
