Desktop Metal Production System P-50

The Desktop Metal Production System P-50 is a binder jetting metal printer sized for volume work: a 490 x 380 x 260 mm (19.2 x 15.0 x 10.2 in) build box, a maximum build rate of 12,000 cc/hr (732 in3/hr) at 65 µm layer thickness, and Single Pass Jetting as its print technology.

Print direction is bi-directional, so the carriage does productive work on passes in both directions instead of returning empty. The binder jetting module carries 8 piezo-electric printheads with 16,384 nozzles and a native resolution of 1,200 dpi. Layer thickness is adjustable from 30 µm to 200 µm in the green state. The headline build rate is quoted at 65 µm, so a job run at thinner layers for finer detail will build more slowly than that maximum, and a job at thicker layers trades surface detail for output.

Part tolerance is listed as ± 0.5%. A percentage means the absolute deviation grows with feature size, which is the point to weigh for larger parts: critical fits on long dimensions should be given machining stock. The material platform is open, with third party MIM powders named, so powder sourcing is not tied to a single supplier. The chamber runs under CDA or nitrogen inerting at less than 2% oxygen.

This is a factory-floor machine. External dimensions are 1,900 x 5,000 x 1,900 mm (74.8 x 196.9 x 74.8 in) and it weighs 4,751 kg (10,476 lb). Power is 380 - 480 V, 50/60 Hz, 3-phase, 4 wire at 60 Amp, and operators work from a 24-inch touchscreen display. Desktop Metal's table for the P-50 covers the printer only and gives no figures for the equipment that follows printing, so the rest of the line has to be planned and quoted separately.
