Stereolithography (SLA) is the oldest additive manufacturing technology, and it is a 3D printing technology used to create industrial concept models, rapid prototypes or different parts with complex geometries in a very short time. By SLA technology, it is possible to manufacture parts with extremely high feature resolutions and quality surface finishes, using a wide selection of materials. SLA 3D printing is frequently used for manufacture: the parts requiring high accuracy and features as small as 0.07 mm, smooth surfaces with good rugosities and form and fit testing. In this article were presented the mechanical properties of the photo-curable polyurethane resins used in SLA technology, the SEM analysis and for establish the composition contain, it was used the ATR-FTIR analysis. In conclusion, new photo-curable polyurethane resins, used in SLA technology, allow the creation of parts with a high degree of accuracy, with good mechanical properties, which can be used both in industry and in medicine domain.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
