Traditional selective laser sintering (SLS) printers require operators to clean the optics before every print—a process that often means taking apart complex components. The Fuse 1 simplifies this with an optical cassette that protects the optics and allows for quick, tool-free removal and installation.

The cassette enables a cleaner, more consistent maintenance process, making it easier for operators to meet print-ready conditions and maintain high throughput in SLS workflows.

Tool-Free Optics Maintenance

The optical cassette is designed for quick, tool-less removal and installation, streamlining cleanup and reducing downtime.
