Overview
The GF Machining Solutions DMP Factory 350 is the production-optimized variant of the DMP 350 platform, designed for continuous, high-throughput metal additive manufacturing in factory environments. While the DMP Flex 350 emphasizes application flexibility and material changeover, the DMP Factory 350 adds integrated powder management and continuous build capability for 24/7 production operations.
The Factory configuration features the same single 500 W fiber laser and 275 x 275 x 420 mm build volume as the Flex 350, but adds a removable print module that enables one build to be depowdered and post-processed while the next build is already running. This overlap capability dramatically increases machine utilization compared to batch-mode systems where the machine sits idle during part removal and chamber preparation.
The integrated powder management system automatically handles powder sieving, recycling, and reloading in an inert atmosphere, maintaining the < 25 ppm O₂ environment that is critical for reactive metals like titanium. This closed-loop powder handling reduces operator exposure to metal powders and ensures consistent material quality across production campaigns.
The taller machine frame (2,370 x 2,400 x 3,470 mm versus 2,869 mm for the Flex) accommodates the additional powder management infrastructure. For manufacturers running dedicated material campaigns in production quantities, the Factory 350 delivers higher overall equipment effectiveness (OEE) than the Flex variant through reduced changeover time and continuous build operations.

Strengths & Limitations
Strengths
- Removable print module enables continuous build operations with minimal machine downtime
- Integrated closed-loop powder management maintains material quality in inert atmosphere
- Same build precision and material quality as DMP Flex 350 in a production-optimized package
- Reduced operator exposure to metal powders through automated handling systems
- Higher OEE than batch-mode systems through overlapped build and depowdering cycles
- Vacuum-based atmosphere (< 25 ppm O₂) critical for production-grade reactive metal processing
Limitations
- Single-laser configuration limits build speed compared to Dual Factory variant
- Taller machine frame (3,470 mm) may require ceiling height considerations
- Less flexibility for material changeover compared to DMP Flex 350 — optimized for dedicated campaigns
- Higher capital cost than Flex variant for the integrated powder management infrastructure

Frequently Asked Questions
01
The Factory 350 adds a removable print module and integrated powder management for continuous production operations. The Flex 350 emphasizes material changeover flexibility for R&D and multi-material environments. Both share the same laser, build volume, and part quality specifications.
02
The removable print module allows one completed build to be extracted for depowdering and post-processing while a fresh module is loaded for the next build. This eliminates the machine downtime normally required for part removal and chamber preparation, increasing overall equipment utilization.
03
While it can handle R&D work, the Factory 350's value proposition centers on continuous production. For shops primarily doing R&D, prototyping, or frequent material changes, the DMP Flex 350 offers better value and operational flexibility.
04
The integrated system automatically sieves used powder, separates oversized particles, recycles acceptable powder back to the hopper, and maintains the entire process under inert atmosphere. This closed-loop system reduces waste, ensures consistent powder quality, and minimizes operator exposure to metal powders.
