Streamlining SLS Post-Processing with the Formlabs Fuse Blast

The introduction of the Formlabs Fuse Blast by Formlabs marks a significant advancement in the realm of SLS 3D printing, offering an automated solution to the traditionally manual and time-consuming process of media blasting and polishing SLS printed parts. An affordable, industrial-quality cleaning and polishing system, the Fuse Blast enhances efficiency, part quality, and user experience.

Adding Fuse Blast as a complement to Fuse Sift in the post-processing workflow reduces cleaning time to as little as 15 minutes overall — an 80% reduction in average hands-on labour time. The automated system blasts parts with media as they revolve in a tumbler, efficiently removing loose and semi-sintered powder from the surface to produce a smooth part with no powder residue. Fuse Blast also features an optional polishing system for customer-grade parts that present a smooth, semi-gloss, and dye-ready surface finish.

Although the Fuse Blast is produced by Formlabs it is also the perfect fit for automating the post-processing of polymer powder bed fusion parts from the likes of HP MJF, 3D System SLS, EOS, WeMatter, Sinteratec, Sinterit and so on.
