Overview

The DN Solutions DLX 450 is the larger single-laser PBF system in the DLX lineup, stepping up to a 450 x 450 x 450 mm build volume that opens the door to bigger aerospace structures, larger tooling inserts, and multi-part build nesting that smaller platforms can't handle. It's a meaningful size increase over the DLX 325 — nearly double the build area — which makes it suitable for parts that simply don't fit on a 325 mm platform.

The build volume of 450 x 450 x 450 mm (17.7 x 17.7 x 17.7 in) is a perfect cube, which simplifies build planning and nesting. The single Yb-Fiber laser comes in 500W or 1000W options with the same 3-axis optical system and 80-micron focus diameter as the DLX 325. The larger build area means longer scan times per layer, making the 1000W option especially valuable for maintaining reasonable build times on larger parts.

The optical system has to cover a 90% larger area than the DLX 325 with the same focus quality, which is a real engineering challenge. DN Solutions addresses this with their 3-axis galvanometer system that maintains consistent spot characteristics from center to edge. Bidirectional recoating handles the wider powder bed efficiently, and advanced scanning strategies optimize laser pathing for the larger build field.

Exchangeable build containers are even more valuable at this scale — swapping a fully-built 450 mm container to start a new build takes minutes rather than waiting through a full cooldown and unload cycle. The machine runs the same material palette: aluminum, titanium, copper, Inconel, maraging steel, and stainless steels under argon or nitrogen atmosphere.

At 5,500 kg (12,125 lb) with a 4,600 x 4,100 mm (181.1 x 161.4 in) footprint, the DLX 450 is about 20% heavier and 10% larger than the DLX 325. It competes with the EOS M 400, Trumpf TruPrint 3000, and SLM Solutions SLM 500 in the large-format single-laser segment.

Strengths & Limitations

Strengths

450 x 450 mm build area is nearly double the DLX 325, enabling larger parts and more efficient multi-part nesting
Cubic 450 mm build volume simplifies build planning for parts of various orientations
Exchangeable build containers are especially valuable at this scale, minimizing downtime between builds
1000W laser option is essential for keeping build times manageable on the larger platform
Same material compatibility as the DLX 325 — no compromise on material options with the larger format
Consistent optical system quality from center to edge across the full 450 mm build area

Limitations

Single laser on a 450 mm platform means layer times are significantly longer than dual-laser alternatives
Larger build volume means more powder inventory, higher material cost per build, and more powder management overhead
5,500 kg weight and larger footprint need more floor space and foundation support than the DLX 325
Longer build times per layer increase thermal management challenges and potential for residual stress
Newer AM platform from a company primarily known for subtractive — material parameter library may be less mature

Best For

Aerospace manufacturers printing larger structural brackets, housings, and components that don't fit on 325 mm platforms Tooling companies building large conformal cooling mold inserts in maraging steel Service bureaus that need to nest multiple medium-sized parts efficiently in a single build Production environments printing larger titanium or Inconel components for aerospace and power generation Facilities that need a larger build volume but don't require the throughput of a dual-laser system

Frequently Asked Questions

01 What does the DN Solutions DLX 450 cost?

New DLX 450 pricing typically ranges from $550,000 to $900,000 depending on laser power and options. The larger build volume commands a premium over the DLX 325, and the 1000W laser is almost essential at this platform size to keep build times reasonable.

02 How much longer do builds take on the DLX 450 vs the DLX 325?

For the same part at the same parameters, build time is roughly the same because you're only melting the part geometry. But layer recoating time increases with the wider powder bed, and if you're filling the build plate with more parts, total build time scales with total melted area per layer. The 1000W laser helps offset the longer scan paths on larger cross-sections.

03 Should I choose the DLX 450 or the DLX 325 D for higher throughput?

It depends on your parts. If you need the larger build area for individual parts over 325 mm, the DLX 450 is your only choice. If your parts fit on a 325 mm platform and you need faster build speed, the dual-laser DLX 325 D will outperform the single-laser DLX 450 on throughput for same-size parts.

04 How much powder does the DLX 450 use per build?

Powder consumption depends on part geometry, nesting density, and build height. The 450 x 450 mm powder bed requires significantly more powder inventory than the 325 mm platform — expect to maintain 300-500 kg of powder in circulation minimum, depending on material. Material cost is one of the biggest operational expenses in PBF.
