SLM 280

The SLM 280 is a DMLS 3D printer from SLM Solutions (Nikon) with a 280 x 280 x 365 mm build volume.

Specifications

Here are the technical specifications for the Nikon SLM Solutions SLM 280 (including the 2.0 and PS models) based on the provided sources:

• Build Volume: 280 x 280 x 365 mm³ (the actual Z-height is reduced slightly by the thickness of the substrate plate) .
• Hotend & Nozzles: Not applicable. Because this is a Selective Laser Melting (SLM) metal 3D printer, it utilizes fiber lasers instead of hotends and nozzles [6, 7]. It can be configured with single, twin, or dual laser optics (options include 400W, 700W, or 1x 700W and 1x 1000W configurations) [6, 8, 9]. The beam focus diameter is 80 - 115 µm [2, 4, 9].

Calibration

The Nikon SLM®280 (including the 2.0 and PS versions) is an industrial Selective Laser Melting (SLM) 3D printer that uses high-powered lasers to fuse metal powder bed layers .

Because it is a laser powder bed fusion (LPBF) machine rather than a Fused Deposition Modeling (FDM) printer, it does not use filament, an extruder, or a nozzle. Therefore, standard FDM calibrations like e-steps, extrusion flow rate, nozzle PID, retraction, and pressure advance do not apply to this equipment [4, 5].

Common defects

Materialise Build Processor (BP) Software Bug

• Symptom: Printed parts exhibit visible lines and structural defects in areas where layers are incorrectly 3D printed .
• Cause: A bug in the Materialise SLM Solutions Build Processor (versions 3.1 and 3.2) generates a partially incorrect exposure order when parts feature both inner and outer borders. The system incorrectly exposes sections of the outer part borders before the inner borders [1, 2].
