Frequently asked
How is the A100 different from cheaper “metal printers”?
It is laser powder-bed fusion (LPBF): a laser melts metal powder directly into fully dense, isotropic parts at ~±0.1% in one step. Filament-and-sinter printers add a separate furnace step and shrink ~20% — the A100 does not.
Can I order online?
Yes — you can order the base A100-300 online to reserve your build slot, with a 12–16 week lead time. For higher laser power (500/1000 W), the optional blue laser, or the 900 °C platform, request a quick quote so we configure the right model.
