Overview
The DN Solutions DLX 325 D is the dual-laser version of the DLX 325 PBF additive manufacturing system, doubling the laser count to significantly boost build speed and throughput. The "D" stands for dual laser — two Yb-Fiber lasers working simultaneously across the 325 x 325 mm build area, each capable of reaching any point on the platform.
Build volume measures 325 x 325 x 420 mm (12.8 x 12.8 x 16.5 in), with a slightly taller Z-height than the single-laser DLX 325 (420 vs 400 mm). Both lasers can work independently on separate areas of the same layer or focus on the same region for faster processing of dense cross-sections. Available in 500W or 1000W per laser, the fully-loaded configuration delivers 2000W of total laser power on a 325 mm platform — serious processing speed.
The 3-axis optical system maintains consistent spot quality for each laser across the full build area, with an 80-micron focus diameter matching the single-laser model. Advanced scanning strategies coordinate the two lasers to minimize heat buildup and warping while maximizing throughput. Bidirectional recoating completes the picture for efficient layer processing.
Exchangeable build containers carry over from the single-laser model, keeping changeover times short. The machine processes the same broad material palette: aluminum alloys, titanium (Ti-6Al-4V), copper, Inconel, maraging steel, and stainless steels under argon or nitrogen atmosphere. Permanent chalk gas filtration handles the increased volume of condensate and spatter from dual-laser operation.
At 4,500 kg (9,921 lb) with a 4,500 x 3,800 mm footprint, the DLX 325 D matches the single-laser model's physical specs. The dual-laser configuration typically adds 30-70% build speed improvement depending on part geometry and nesting — not a full 2x due to scan strategy coordination overhead, but a meaningful productivity gain that shortens the business case for production AM. Competes with the SLM 280 2.0 dual-laser and EOS M 400 in the multi-laser mid-size segment.

Strengths & Limitations
Strengths
- Dual lasers deliver 30-70% faster build times versus the single-laser DLX 325 depending on part geometry
- Both lasers can reach the entire build area, enabling flexible scan strategies for optimal throughput and quality
- 420 mm Z-height gives 20 mm more build depth than the single-laser model for taller parts
- Exchangeable build containers maintain production efficiency during changeovers and material switches
- 2000W total laser power (with 1000W option) provides serious throughput on dense cross-section parts
- Same footprint as single-laser model — no additional floor space needed for the productivity upgrade
Limitations
- Significant price premium over the single-laser DLX 325 — ROI requires sufficient production volume to justify dual lasers
- Dual-laser coordination adds software complexity and requires more parameter development for new materials
- Higher consumable costs from increased laser operating time and more frequent optical component replacement
- DN Solutions' additive application team is still building depth compared to EOS and SLM Solutions
- Stitch zone quality between laser fields needs careful parameter tuning to avoid visible seams in production parts

Frequently Asked Questions
01
New DLX 325 D pricing typically ranges from $600,000 to $950,000 depending on laser power configuration and ancillary equipment. The dual-laser premium over the single-laser DLX 325 is roughly $200,000-$250,000, which needs volume to justify.
02
Real-world speed improvement ranges from 30% to 70% depending on part geometry and nesting strategy. Parts with large cross-sectional areas benefit most because both lasers can work simultaneously across more of each layer. Small, sparse builds see less improvement because there's less area for the second laser to work on.
03
Stitch zones where the two lasers' scan areas overlap require careful parameter development to avoid visible seams and property differences. DN Solutions' advanced scanning strategies address this, but initial parameter validation for new materials should include stitch zone testing and mechanical property verification.
04
The DLX 325 and DLX 325 D aren't upgrade paths — they're separate machines. If you know your production volumes will require dual-laser throughput within 1-2 years, buying the D upfront avoids purchasing two machines. If you're exploring AM or running lower volumes, the single-laser DLX 325 reduces initial investment risk.
