Elastic (Silicon-like) Resin Material Details


General Informations

Elastic50A Resin, tailored for Stereolithography 3D printing (SLA), offers a unique blend of features that are particularly appealing to researchers, medical professionals, and point-of-care printing enthusiasts. This resin begins as a liquid material and solidifies through a UV laser-induced polymerization process. Components crafted with SLA technology boast an exceptionally smooth surface finish and remarkable precision. Elastic50A Resin has been meticulously designed to replicate the qualities of silicone, making it an invaluable resource in various applications.

Softness and Flexibility Elastic50A Resin distinguishes itself with its remarkable softness and flexibility. While it aims to mimic silicone, it's important to note that its properties are not identical due to the UV curing process. This material lacks meltability and exhibits a degree of brittleness compared to vulcanized silicone.

Ideal for Immersive Environments One significant advantage of SLA-printed components is their inherent density and resistance to water, rendering them ideal candidates for applications involving submersion and water flow assessments. Moreover, the exceptional surface quality makes Elastic50A Resin exceptionally suitable for deployment in wind tunnel testing and flow analysis scenarios.

Weather Considerations SLA-produced parts are generally not designed for prolonged exposure to adverse weather conditions or UV radiation and are typically reserved for prototyping purposes. Therefore, it is advisable to employ components crafted from Elastic50A Resin in protected environments.

Support Structures In SLA 3D printing, support structures are composed of the same material as the print itself, necessitating manual removal. This characteristic, while common in SLA technology, may impose certain limitations on design freedom when compared to alternative manufacturing methods.
