Standard and beam-shaping configurations
The M 4K-4 1 kW has four 1000 W lasers with an approximately 85 µm focus. The M 4K-4 FLX uses four 1200 W AFX sources and selectable Gaussian-to-ring profiles spanning 85–210 µm. Their electrical consumption specifications differ.
Envelope and installation
Both listed four-laser configurations have a 450 × 450 × 1000 mm build volume. Machine dimensions include the conveyor and the manufacturer recommends about 90 m² of installation space. Taller or six-laser machines mentioned on the page are customization examples, not the standard M 4K-4.

The standard stated build envelope is retained; bespoke height and laser options are separate configurations.
A larger nominal envelope does not establish better print quality. Fit depends on the configuration, usable area, supports, and orientation.
