Selective laser sintering (SLS) is one of our most popular additive manufacturing prototyping methods because of its throughput and capacity for delivering on large projects. During SLS, 3D objects, large and small, are created with tiny particles of powder. They are fused together with heat generated from a high-powered laser, one layer at a time. The unmelted powder is brushed away during post-processing. The resulting parts are durable, stable, and accurate, eliminating the need for many machining, tooling, casting, or other secondary operations. The parts can be sent to our in-house finishing department.
Our SLS Department can create durable plastic parts directly from many solid CAD models in just days—and, in most cases, as soon as the next day. Now that’s rapid prototyping. Most of our SLS prototypes are made from nylon, glass-filled nylon, and elastomer.
Midwest Composite Technologies uses two platform sizes:
- The larger build envelope is 26.6 x 15 x 22.9 inches. Parts made in large-platform SLS are produced within an accuracy of +/-.005 inch or +/-.0015 inch per inch, whichever is greater.
- The smaller build volume is 13 x 11 x 16 inches.Parts made in small-platform SLS are produced within an accuracy of +/-.005 inch or +/-.001 inch per inch, whichever is greater.
