Desktop SLS 3D printer

December 28, 2025

The Loopzizo K-100 is a desktop Selective Laser Sintering (SLS) 3D printer currently raising funds on Kickstarter. It is designed to bring industrial-grade SLS technology, which is typically large and expensive, into a compact form factor suitable for small businesses, engineers, and serious hobbyists.

This printer distinguishes itself by using a 5-watt 450 nm diode laser to fuse powder particles, a different approach from the high-power lasers found in large industrial machines. The key advantage of this SLS technology is the ability to print complex geometries with no support structures, as the surrounding unsintered powder supports the part during the build process. It features a build volume of approximately 140 x 140 x 140 mm. The machine offers high precision with a layer thickness of roughly 0.1 mm, capable of producing durable, end-use parts with tensile strength comparable to injection-molded plastics.

In terms of usability and workflow, the K-100 is built to be more user-friendly than traditional industrial counterparts. It includes automated features such as auto-slicing and wireless connectivity for easier job management. The system is enclosed and designed to minimize the mess often associated with powder-based printing. Loopzizo also offers an optional post-processing station, the H1, to streamline the depowdering and powder recovery process, making it feasible to operate in an office or studio environment.
