Overview

The GF Machining Solutions DMP Flex 350 Dual is a dual-laser variant of the DMP Flex 350 platform, doubling the laser power with 2 x 500 W fiber lasers to reduce build times by up to 50% compared to the single-laser model. This configuration bridges the gap between R&D flexibility and production-level throughput, making it the preferred choice for shops transitioning from prototyping to serial metal additive manufacturing.

Both lasers operate at 1,070 nm wavelength and can simultaneously process any area of the 275 x 275 x 420 mm build volume. The full-field overlap capability means both lasers can work on the same layer without restricted zones, maximizing parallel processing efficiency regardless of part geometry or build layout. This is a meaningful advantage over competitive dual-laser systems that assign each laser to a fixed portion of the build area.

The DMP Flex 350 Dual shares the same vacuum-based atmosphere management (< 25 ppm O₂) that distinguishes the entire DMP platform. Combined with dual-laser productivity, this delivers both the material quality benefits of oxygen-free processing and the throughput improvements needed for small-series production of flight-critical aerospace parts, medical implants, and high-value industrial components.

Layer thickness adjustability from 5 µm to 90 µm carries over from the single-laser model, as do the 200 µm minimum feature size, 150 µm minimum wall thickness, and 60 µm positional repeatability. The Dual configuration adds build speed without sacrificing the resolution and accuracy that make the DMP platform suitable for demanding end-use applications.

Frequently Asked Questions

01 How much faster is the Dual compared to the single-laser DMP Flex 350?

GF Machining Solutions reports up to 50% build time reduction with the Dual configuration. Actual speed improvement depends on part geometry and build layout — densely packed builds with large cross-sections see the greatest benefit from parallel laser processing.

02 What does full-field overlap mean for dual lasers?

Full-field overlap means both lasers can access any point across the entire 275 x 275 mm build area. This contrasts with split-field systems where each laser is restricted to one half of the build plate, which limits parallelization when parts straddle the boundary.

03 Are dual-laser parts the same quality as single-laser parts?

Yes. The dual-laser system uses the same optical path quality and calibration standards as the single-laser model. The overlap zones where both lasers work are carefully stitched to avoid density or property variations at the seam boundaries.

04 Can I run the DMP Flex 350 Dual with just one laser?

Yes. The system can operate in single-laser mode when applications require it — for example, when building very small parts where dual-laser parallelization provides minimal benefit, or for specific process development work.
