DN Solutions DLX 450 D

The DN Solutions DLX 450 D combines the largest build volume in this group of metal additive machines, 450 x 450 x 470 mm (17.7 x 17.7 x 18.5 in), with two Yb-fiber lasers rated at 500 W or 1,000 W each. DN Solutions' current lineup listing does not include it, so it may be an older model; treat the figures as a reference and check availability with the manufacturer.

On a plate this large, laser count governs output. A 450 mm square holds many parts, and with one beam each of them waits its turn in every layer. Splitting the work between two beams is what makes a full plate practical as a production run. The single-laser DLX 450 has a 450 x 450 x 450 mm (17.7 x 17.7 x 17.7 in) volume and suits lighter loading.

Build height is 470 mm (18.5 in). Tall builds are long builds, so the machine may run unattended across several shifts, and anything that interrupts it, from gas supply to filter capacity, becomes a planning item. The listed protective gases are argon and nitrogen. Gas filtration is given as "Permanent Chalk", and the table does not explain the term or state a service interval.

Both lasers have an 80 micron focus diameter. As on any two-laser machine, parts that cross from one scan field into the other rely on the alignment between the beams. That alignment is not described in the table and is worth a demonstration part before acceptance.

The machine measures 4,600 x 4,100 x 2,800 mm (181.1 x 161.4 x 110.2 in) and weighs 5,500 kg (12,125 lb). Electrical supply, powder handling, layer thickness and materials are not in the table.
