Overview

The DN Solutions DLX 325 is a single-laser Powder Bed Fusion (PBF) additive manufacturing system that marks DN Solutions' entry into the metal 3D printing space. It's a notable move from a company known primarily for subtractive machining — and it signals their intent to offer complete manufacturing workflows from powder to finished part when paired with their CNC machines.

The build volume measures 325 x 325 x 400 mm (12.8 x 12.8 x 15.7 in), which puts it in the mid-range for industrial PBF systems. That's enough room for most aerospace brackets, medical implants, tooling inserts, and small structural components. The single Yb-Fiber laser comes in 500W or 1000W power options through a 3-axis optical system with an 80-micron focus diameter. The 1000W option significantly speeds up build times for larger cross-sections.

The 3-axis optical system provides consistent spot quality across the full build area, which is important for part-to-part consistency in production environments. An 80-micron focus diameter strikes a balance between detail resolution and build speed — fine enough for detailed features while maintaining reasonable layer times. Advanced scanning strategies with bidirectional recoating help optimize build quality and reduce recoater-related defects.

Exchangeable build containers are a practical feature that minimizes changeover time between jobs or material changes. In a production environment, you can be prepping the next build while the current one runs. The machine runs under argon or nitrogen protective gas atmosphere depending on the material being processed, with a permanent chalk gas filtration system.

Supported materials include aluminum alloys, titanium (Ti-6Al-4V), copper alloys, Inconel, maraging steel, and stainless steels — covering the most common industrial PBF materials. At 4,500 kg (9,921 lb) with a 4,500 x 3,800 mm (177.2 x 149.6 in) footprint, the DLX 325 needs dedicated floor space but isn't massive by industrial standards. It competes with systems from EOS (M 290), SLM Solutions (SLM 280), and Trumpf (TruPrint 2000) in the mid-size single-laser PBF segment.

Strengths & Limitations

Strengths

Exchangeable build containers minimize changeover time between jobs and material changes for production efficiency
1000W laser option significantly speeds up build times for larger cross-sections versus the 500W standard
Wide material compatibility including titanium, Inconel, copper, aluminum, and stainless steels
Comes from a major machine tool manufacturer, so integration with CNC post-processing workflows is a natural fit
80-micron focus diameter balances detail resolution with build speed for most industrial applications
Bidirectional recoating with advanced scanning strategies reduces defects and improves part quality

Limitations

Single laser limits build speed compared to multi-laser systems like the DLX 325 D or competing dual/quad-laser platforms
DN Solutions is newer to additive than EOS, SLM Solutions, or Trumpf — the application knowledge base is still growing
325 mm build area is restrictive for larger aerospace and automotive parts that need 400+ mm platforms
PBF systems require significant ancillary equipment (powder handling, sieving, heat treatment) that adds to total investment

Best For

Manufacturing facilities already running DN Solutions CNC machines who want to add in-house metal AM capability Aerospace shops printing titanium and Inconel brackets, fittings, and structural components Medical device manufacturers producing patient-specific titanium implants and surgical guides Tooling shops creating conformal cooling inserts in maraging steel for injection mold applications R&D departments evaluating metal PBF for production applications with a mid-range build volume

Frequently Asked Questions

01 What does the DN Solutions DLX 325 cost?

New DLX 325 pricing typically falls between $400,000 and $700,000 depending on laser power (500W vs 1000W) and ancillary equipment packages. Total cost of ownership including powder handling, gas supply, and post-processing equipment can push the initial investment to $800,000+.

02 How does the DLX 325 compare to the EOS M 290?

The EOS M 290 has been the industry workhorse for years with a proven track record and extensive material parameter library. The DLX 325 offers a similar build volume (325 x 325 vs 250 x 250 mm) with exchangeable build containers. The DN Solutions machine offers a larger build area but EOS has deeper application expertise and a larger installed base.

03 Should I choose the 500W or 1000W laser?

The 1000W laser significantly reduces build times for parts with larger cross-sections by melting more material per pass. If you're building dense, large-area parts in titanium or Inconel, the 1000W pays for itself quickly through throughput gains. For smaller, detailed parts where resolution matters more than speed, the 500W is sufficient.

04 What post-processing do PBF parts require?

PBF parts typically need stress relief heat treatment on the build plate, wire EDM or band saw removal from the plate, support structure removal, heat treatment for final properties, and CNC machining of critical surfaces. DN Solutions' CNC lineup makes the post-machining step a natural extension of their workflow.
