Vat photopolymerization Hero

SLA is a type of photopolymerization capable of producing parts with an excellent surface finish and small feature resolution. While SLA is not typically suitable for high-performance applications, its intricate and accurate detailing make it a popular option for prototypes. Our factory uses Formlabs Form 3 SLA 3D printers.
