The Formlabs Fuse Series IR Sensor O-ring Kit is a maintenance spare parts pack containing 2 replacement O-rings for the infrared sensor assembly in Formlabs Fuse 1+ and Fuse 1+ 30W SLS 3D printers. The IR sensor monitors powder bed temperature and other key process parameters during printing, and a properly sealed sensor is essential for accurate readings and stable SLS print results.

O-rings in SLS printer environments are subject to heat, powder exposure and mechanical wear over time. Replacing worn or damaged O-rings as part of a regular preventive maintenance schedule keeps the IR sensor sealed and protected, preventing powder ingress that could impair sensor performance or lead to measurement errors. Keeping this kit in stock ensures maintenance can be performed immediately when needed without waiting for parts.
