What is SLA 3D Printing Technology and How Does It Work?

SLA (Stereolithography) is one of the earliest and most widely used additive manufacturing technologies. Unlike traditional subtractive manufacturing, SLA builds parts layer by layer using a UV laser to cure liquid photopolymer resin into solid parts. This technology ensures high precision, smooth surface finish, and detailed features, making it ideal for prototypes and functional models.

What Are 3D Printing Supports and When Do You Need Them?

In additive manufacturing, parts are built layer by layer. But what happens when a layer has nothing underneath to support it? That’s where 3D printing supports come in. These temporary structures prevent overhangs or bridges from collapsing, ensuring successful prints with better accuracy.
