How much does the SLM Solutions SLM 800 cost?
Estimated price range
Our best estimate for a metal additive manufacturing in this class — not a quote from SLM Solutions. Configuration moves it a long way.
Overview
The SLM 800 is a tall-format quad-laser machine: four 700 W lasers over a 500 × 280 × 850 mm build volume, with a build rate of up to 171 cm³/h. Its plate area matches the SLM 500 Quad, which builds in 500 x 280 x 365 mm (19.7 x 11 x 14.4 in) with 4 x 700 W fiber lasers. What the 800 adds is height: 850 mm of Z, more than twice the 365 mm of the SLM 500 Quad.
That makes it a machine for long parts built upright, or for stacking several tiers of smaller parts in one job so the machine runs unattended for longer. Laser power is the same as on the SLM 500 Quad, so the extra height does not come with extra melting capacity. A full-height build is simply a long one, and the gain is in part length and parts per job.
Layer thickness runs from 20 – 90 µm. Accuracy is stated as ±0.1 mm or ±0.1%, whichever is greater, which means the percentage term takes over on large dimensions and the tolerance band widens with the part. Plan finishing stock on long features accordingly. Listed materials are titanium alloys, nickel superalloys, aluminum alloys, stainless steel, tool steel and cobalt-chrome.
The machine weighs approx. 8,500 kg, about double the approx. 4,200 kg (9,259 lb) of the SLM 500 Quad, so foundation and rigging need checking early.

Strengths & Limitations
Strengths
- 850 mm of build height on a 500 × 280 mm plate, more than twice the 365 mm Z of the SLM 500 Quad
- Four 700 W lasers with a build rate of up to 171 cm³/h
- Stated accuracy of ±0.1 mm or ±0.1%, whichever is greater
- Layer thickness from 20 – 90 µm across titanium, nickel, aluminum, stainless, tool steel and cobalt-chrome alloys
Limitations
- Approx. 8,500 kg machine weight, about double the approx. 4,200 kg (9,259 lb) of the SLM 500 Quad
- Plate area stays at 500 × 280 mm, so the extra capacity only helps parts that can be oriented or stacked in Z
- Accuracy loosens with size: the ±0.1% term governs on large dimensions
- The table gives no footprint or utility figures, which have to come from SLM Solutions before site planning

Frequently Asked Questions
01
Build height and machine size. Both use 4 × 700 W lasers on a 500 × 280 mm plate. The SLM 800 has 850 mm of Z and weighs approx. 8,500 kg, while the SLM 500 Quad has 365 mm of Z (500 x 280 x 365 mm, 19.7 x 11 x 14.4 in) and weighs approx. 4,200 kg (9,259 lb).
02
SLM Solutions states ±0.1 mm or ±0.1%, whichever is greater. On small features the fixed ±0.1 mm applies. On large dimensions the percentage is the larger number, so the tolerance scales with the part. Critical faces on long parts are normally left with stock for machining.
03
Titanium alloys, nickel superalloys, aluminum alloys, stainless steel, tool steel and cobalt-chrome, at layer thicknesses from 20 – 90 µm. The table names alloy families, not grades, so confirm the specific grade and its parameter set with SLM Solutions.
