Single-laser model and twin-laser sibling
The August 2022 sheet lists FS421M with one 500 W laser and FS421M-2 with two. This record describes the single-laser model, including its approximately 3450 kg weight; the dual model is about 3500 kg.
Powder circuit and build geometry
An inert closed-loop system integrates powder supply, feeding and recycling. A rail system supports build-cylinder exchange. The 425 × 425 × 420 mm stated space excludes build-plate thickness, and the usable volume still depends on the part and material. Open parameters allow material and process development.

The August 2022 official sheet distinguishes the single-laser FS421M (one 500 W laser, approximately 3450 kg) from FS421M-2 (two lasers). Its stated build-cylinder dimensions exclude the build plate; usable geometry remains material- and setup-dependent. Present ordering status is not established.
A larger nominal envelope does not establish better print quality. Fit depends on the configuration, usable area, supports, and orientation.
