The Formlabs Fuse Build Chamber Inner Gasket is an OEM sealing component for the Fuse 1 SLS 3D printer, positioned at the inner section of the build chamber to create a tight seal that preserves the nitrogen atmosphere required for high-quality SLS sintering. The inner gasket works together with the external frame gasket to create a fully sealed chamber environment.

Replace the inner gasket when signs of degradation, compression set, or gas leakage are detected, causing the nitrogen purity level to drop below optimal levels. Maintaining both the inner and external gaskets is essential for consistent sintering energy distribution, reliable part quality, and repeatable SLS production results. Also available: Formlabs Fuse 1 Build Chamber External Frame Gasket (art. 210000004853).

Key features

• OEM inner gasket for the Formlabs Fuse 1 build chamber, sealing the inner chamber perimeter for nitrogen containment.
• Works in combination with the external frame gasket to create a fully sealed, nitrogen-atmosphere build environment.
• Prevents nitrogen loss that would reduce sintering quality and affect part mechanical properties.
• Genuine Formlabs material and dimensions for correct compression fit and reliable long-term sealing.
• Also available: Fuse 1 Build Chamber External Frame Gasket (art. 210000004853) for the outer seal position.
