Formlabs Fuse Series Optical Cassette

Formlabs Fuse Series Optical Cassette — a replaceable optical assembly for the Fuse 1 and Fuse 1+ 30W printers, which protects the SLS printing laser path from powder contamination. The cassette is fixed in the cassette carriage under the print chamber's ceiling cover and is removed for inspection after each print. Replacing a contaminated cassette with a clean one eliminates the risk of glass window flashing and maintains stable sintering quality.

Key Advantages

• Laser path protection. The cassette's glass windows block powder from reaching the laser optics, maintaining stable sintering power layer by layer.
• Quick access via the cassette carriage. A thumbscrew in the upper front corner of the print chamber opens the carriage without disassembling the printer.
• Simple replacement without special tools. The cassette slides out of the carriage in one motion, and a clean part is installed in its place within minutes.
• Sealing rubber gasket. The gasket secures the cassette in the carriage and prevents powder from entering the printer's internal cavity.
• Compatibility with the Fuse 1 generation. The Formlabs Fuse Series Optical Cassette is designed specifically for the Fuse 1 and Fuse 1+ 30W printers. It requires no additional setup after installation.

Areas of Application

• Routine SLS printing maintenance: inspecting and replacing the Formlabs Fuse Series Optical Cassette after each print prevents powder build-up on the glass. This maintains laser exposure accuracy.
• High-frequency printing operations: a replaceable cassette allows quick restoration of a clean optical path between cycles without downtime for printer diagnostics.
• Service workshops and engineering departments: a ready-made replacement assembly reduces the repair of Fuse 1 and Fuse 1+ 30W printers to replacing a single part.
• Sintering quality control: clean cassette optics eliminate local defects caused by laser flashing through contaminated glass.

Compatibility and Identification

Storage and Handling

• Transport and storage: keep the cassette on a clean, flat surface with the gasket facing upwards, without touching either of the glass windows.
• Protection during maintenance: use a new pair of nitrile gloves, as powder and skin oils leave stains on the cassette glass.
• Reinstalling into the printer: close the cassette carriage and tighten the thumbscrew immediately after installation to prevent dust ingress.
