Ideas too large for a print bed?
Stereolithography, also known as SLA or SL for short, is the veteran of 3D printing technologies. It’s been around at Materialise since 1990, and continues to be one of the most widely-used rapid prototyping technologies for plastic models.
How Does Stereolithography Work?
Stereolithography is a laser-based technology that uses a UV-sensitive liquid resin. A UV laser beam scans the surface of the resin and selectively hardens the material corresponding to a cross section of the product, building the 3D part from the bottom to the top. The required supports for overhangs and cavities are automatically generated, and later manually removed.
Why choose Stereolithography?
When you need a part printed yesterday and delivered right now, Stereolithography is what you want to be looking at. It’s a technology that produces great looking models with impeccable surface quality in no time. At Materialise, we’ve also developed our own patented Mammoth Stereolithography machines that let us build and ship parts in less than a day. And they even give you the freedom to 3D print parts up to 2 meters long in a single build.
Ideal applications for Stereolithography
Visual prototypes for photo shoots and market testing
“Show and tell” parts with smooth surfaces and fine details
Prototypes for limited functional testing
Masters for copying techniques such as Vacuum Casting
Alternatives for sheet metal prototypes when coated with a metal plating process
Low-volume production of complex geometries
