Overview

The GF Machining Solutions DMP Factory 350 Dual combines the production-optimized Factory platform with dual 500 W fiber lasers, delivering the highest throughput configuration in the DMP 350 family for continuous manufacturing operations. This machine represents GF's answer to the growing demand for production-rate metal additive manufacturing with the material quality that aerospace and medical applications demand.

With 2 x 500 W fiber lasers featuring full-field overlap capability, the Factory 350 Dual reduces build times by up to 50% compared to the single-laser Factory 350. Combined with the removable print module for continuous build operations, this creates a production system where high laser throughput meets high machine utilization — the two factors that most directly impact cost-per-part in metal additive manufacturing.

The integrated powder management system operates in the same closed-loop, inert-atmosphere configuration as the single-laser Factory 350, automatically handling powder sieving, recycling, and reloading. The vacuum-based build chamber maintains < 25 ppm O₂ throughout the process, ensuring the material quality that reactive metals like titanium demand at production volumes.

The Factory 350 Dual targets manufacturers who have validated their applications on Flex or single-laser Factory platforms and are ready to scale to production volumes. The combination of dual-laser speed and factory-grade powder management makes it particularly compelling for aerospace structural components, orthopedic implants, and turbomachinery parts where both quality certification and volume economics must be met simultaneously.

Strengths & Limitations

Strengths

Dual 500 W lasers with full-field overlap cut build times by up to 50% in factory configuration
Removable print module enables continuous production without machine idle time
Integrated powder management maintains material quality across production campaigns
Vacuum atmosphere (< 25 ppm O₂) ensures production-grade quality for reactive metals
Highest throughput configuration in the DMP 350 family for series manufacturing
Proven platform scalability from Flex R&D to Factory production

Limitations

Highest capital cost in the DMP 350 family combining dual lasers and factory infrastructure
Taller 3,470 mm frame height requires adequate ceiling clearance
Optimized for dedicated material campaigns — less flexible than Flex variants for material changes
ROI requires consistent production volumes to justify the dual-laser and factory premium

Best For

Frequently Asked Questions

01 How does the Factory 350 Dual compare to the DMP Factory 500?

The Factory 500 offers a much larger 500 x 500 x 500 mm build volume with 3 x 500 W lasers for the largest parts. The Factory 350 Dual has a smaller build envelope (275 x 275 mm) but offers the Factory production infrastructure at a lower price point, suitable for parts that fit within the 350 build plate.

02 Is the Factory 350 Dual the right choice for my first metal AM system?

Generally no. The Factory 350 Dual is best suited for manufacturers who have already validated their applications and are scaling to production. The DMP Flex 350 (single or Dual) offers more flexibility for application development, material exploration, and lower initial investment.

03 Can the Factory 350 Dual run different materials between builds?

Yes, but material changes in a Factory configuration require thorough cleaning of the powder management system. The Factory platform is optimized for dedicated material campaigns rather than frequent changeover. For multi-material flexibility, consider the DMP Flex 350 Dual.

04 What certifications does the DMP Factory 350 Dual support?

The DMP Factory platform supports aerospace (AS9100), medical (ISO 13485), and general manufacturing quality frameworks. The vacuum atmosphere, closed-loop powder management, and full process monitoring provide the traceability and consistency required for certified production.
