Overview

The 3D Systems DMP Factory 350 is an industrial laser powder bed fusion (LPBF) metal 3D printing system designed for high-throughput production of complex metal parts in aerospace, medical, and industrial markets. The machine features a 275x275x420mm build envelope with three 500W fiber lasers operating simultaneously across the powder bed for maximum productivity. 3D Systems builds the DMP Factory 350 around its vacuum chamber architecture — the oxygen level in the process chamber is maintained below 25 ppm, dramatically reducing reactive oxide inclusions in the final part. This enables processing of highly reactive materials including titanium alloys (Ti-6Al-4V), CoCr alloys, and nickel superalloys (Inconel 625, 718) with minimal contamination. The integrated powder recycling module handles unused powder automatically, reducing manual handling and material waste.

Strengths & Limitations

Strengths

Vacuum chamber architecture enables < 25 ppm O2 for reactive metal alloys
3-laser system for faster build rates on production volumes
3DXpert integrated software for design, simulation, and process planning
Proven in FDA-cleared medical implant production workflows
Integrated powder recycling reduces material handling labor

Limitations

Very high capital cost vs single-laser LPBF systems
Vacuum pump maintenance adds operating overhead
275mm x/y build dimensions smaller than EOS M 300-4 (300x300mm)
Surface finish requires post-processing for functional surfaces

Best For

Aerospace structural component and medical implant manufacturers requiring dense, oxide-free titanium and CoCr builds with consistent material properties across production volumes.

Frequently Asked Questions

01 Why does the DMP Factory 350 use a vacuum chamber instead of inert gas purge?

Most LPBF machines use argon or nitrogen gas flow to displace oxygen. The DMP Factory 350 evacuates the chamber and backfills with inert gas, achieving oxygen levels below 25 ppm vs 100-1,000 ppm in conventional systems. This dramatically reduces oxide inclusions in reactive metals like titanium, producing parts with properties closer to wrought material.

02 What medical applications use the DMP Factory 350?

The DMP Factory 350 is widely used for FDA-cleared medical devices including orthopedic implants (spinal cages, acetabular cups, tibial trays) and dental prosthetics in CoCr and titanium. The vacuum process ensures material purity required for implant qualification and biocompatibility testing.
