Electron-beam melting and stacking
Spectra L builds in a cylindrical Ø350 × 430 mm space. The manufacturer describes stacking parts in a semi-sintered powder bed and using supports mainly for thermal management, with removal after the build.
Point Melt control
Point Melt exposes individual locations rather than continuous scan lines. The manufacturer connects this strategy to temperature control, reduced gradients and configurable repeated exposures. The listed powder parameters are titanium Grade 5 and Grade 23; the page does not establish a broader qualified material list.
