GF DMP Factory 350

New DMP Factory 350 systems typically run $600,000 to $1,000,000 depending on configuration. A single laser system with standard powder management starts near the lower end. The triple 500 W laser configuration with expanded 350 x 350 mm build plate and full monitoring suite pushes toward $1 million. The integrated powder management adds a meaningful premium over the comparable DMP Flex 350 configuration.

Choose the Factory 350 if you're running production volumes in one or two dedicated materials and want automated powder management for maximum uptime and consistency. Choose the Flex 350 if you run multiple different alloys and need the removable print module for quick material changeover. The Factory costs more but pays back through reduced operator intervention, better powder quality control, and higher machine utilization in dedicated production. The Flex is better for R&D, prototyping shops, and multi-material bureaus.

After each build, unused powder is automatically collected, conveyed to a sieving station, sieved to remove oversized particles and spatter, and returned to the supply hopper -- all under inert atmosphere (nitrogen or argon). This closed loop maintains consistent powder quality without operator intervention, prevents oxygen pickup on reactive powders like titanium, and provides traceability data on powder usage and recycling. The system tracks powder lot history for quality documentation required in regulated industries.

You can, but it's not designed for frequent changeover. The integrated powder management system needs to be thoroughly cleaned when switching materials, which can take hours to days depending on the material pair and contamination sensitivity. For shops that need to run multiple materials regularly, the DMP Flex 350 with its removable print modules is the better choice. The Factory 350 is optimized for running one material family at production volume.

Both are multilaser LPBF systems targeting production. The EOS M 300-4 offers four 400 W lasers in a 300 x 300 x 400 mm build volume with full-field access. The DMP Factory 350 provides three 500 W lasers in a 350 x 350 x 350 mm volume (triple config). The DMP Factory 350 has higher per-laser power and broader material qualification including copper and refractory metals. EOS has a significantly larger install base, more published parameters, and broader ecosystem. Both have integrated powder management for production use.

The machine includes layer-by-layer imaging for post-build analysis and process monitoring through the 3DXpert software platform. Powder bed quality is monitored to detect recoating anomalies. The automated powder management provides traceability data including sieve records and lot tracking.
