SLA was was invented way back in 1986 and was the technology used to manufacture the very first 3D printed parts. The SLA method utilizes a vat photopolymerization process and the materials used in SLA are mostly thermoset polymers that come in a liquid form. This 3D printing method provides extremely high detail without introducing excessive costs. As with any manufacturing method, designers must take advantage of the benefits and limitations of the SLA manufacturing process in order to achieve the best results. Read this article to learn more about SLA 3D printing and common SLA applications.
