sPro 140


Produce end-use 3D printed thermoplastic and composite parts with a high level of impact resistance, surface finish and precision, and with a broad range of available materials.

With its combination of production speed, high throughput and capacity, and excellent part quality, the sPro 140, produces robust 3D printed end-use parts up to 550 mm length or large amount of parts, nested in the full 22 x 22 x 18 in (550 x 550 x 460 mm) build volume. This SLS (Selective Laser Sintering) production printer produces durable parts for a multitude of applications such as housings, machinery components, complex end-use parts such as ductings, functional test parts and assemblies, as well as healthcare products and tools.

High-capacity part manufacturing

With its high production speed and the ability to stack parts in the entire build volume, the sPro 140 offers both a faster and a more economic solution to other printer technologies.


Impact-resistant, durable parts

Our customers count on this robust printer for the toughest applications, year after year. It offers far superior living hinges, snap fit and other mechanical joints than any other technology. With a broad range of materials to match your requirements, the sPro 140 produces strong parts with high thermal and chemical resistance. And it is the most economical thermoplastic solution for large quantities of parts.
