Nikon SLM Solutions SLM 280 2.0 — Technical data

The SLM 280 2.0 is Nikon SLM Solutions' mid-size LPBF system and the current stage of the long-running SLM 280 platform. Its build envelope measures 280 × 280 × 365 mm, and it is fitted with either one or two 700 W fibre lasers; layer thickness can be set between 20 and 90 µm. Typical uses are prototypes and medium volumes in aerospace, energy, tooling and research. The powder system is open, so titanium, nickel, aluminium, steel and copper powders from other suppliers can be processed as well. For series production with a closed powder loop there is the sister model SLM 280 PS.

When buying a used machine, first establish the laser configuration: earlier 2.0 units were also shipped with 400 W lasers or as a dual version with 700 W and 1000 W. After that, the hours on each laser, the condition of recoater and protective glass, the filter type (cartridge or PFM) and complete service records matter most. At the new site the machine needs a 63 A three-phase supply, clean compressed air and an argon supply.
