Fuse 1

The Fuse 1 is an SLS 3D printer from Formlabs with a 165 x 165 x 300 mm build volume.

Specifications

The Formlabs Fuse 1 is a Selective Laser Sintering (SLS) 3D printer, which fundamentally differs from Fused Deposition Modeling (FDM) technology . Here is the verification of the technical specifications you requested based on the provided sources:

• Hotend & Nozzles: Not applicable. Because it is an SLS printer, it does not use a hotend or nozzles. Instead, it utilizes a 10-Watt Ytterbium Fiber laser (1065 nm wavelength) with a 200-micron spot size to selectively sinter polymer powder .
• Bed: The print bed is an aluminum plate that steps downward along the Z-axis as each new layer is printed [3, 5].

Calibration

The Formlabs Fuse 1 is a Selective Laser Sintering (SLS) 3D printer that uses a laser to fuse polymer powder, rather than a Fused Deposition Modeling (FDM) printer that extrudes filament [1, 2]. Because of this completely different technology, standard FDM calibration metrics like e-steps, flow rate, PID tuning, retraction, first-layer squish, and pressure advance do not apply to the Fuse 1.

Instead, the Fuse 1 relies on thermal, optical, and powder-dosing calibrations.

Common defects

Here is a detailed breakdown of the defects, bugs, weak points, and failures associated with the Formlabs Fuse 1 and Fuse 1+ 30W, based on the sources provided.

Defects, Bugs, and Failures

1. Laurolactam (White Powder) Buildup

• Symptom: Fluffy white deposits accumulate on the printer’s touchscreen, optical cassette, IR sensor, exhaust fan, and exterior sheet metal . This can obscure the camera/sensors or trigger errors like "Chamber Pressure Too High" .
