Design Guidelines: Selective Laser Sintering

Our basic guidelines for selective laser sintering include important design considerations to help improve part manufacturability, enhance cosmetic appearance, and reduce overall production time.

We offer a number of secondary services to further enhance your 3D-printed project design or finish. These services are available when ordering a part manufactured by Proto Labs.

Equipment

Our SLS equipment includes sPro140 machines, which have a large sintering build volume, and feature fully digital high-speed scanning systems, unparalleled process consistency, and closed systems for powder blending and delivery for reliable part quality. We also use SPro 60 machines, which allow for multiple materials and high throughput.
