How much does the SLM Solutions SLM 800 Quad 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 Quad is listed as a large-format Selective Laser Melting (SLM / LPBF) machine with four 700 W Yb-fiber lasers and a build volume of 800 x 400 x 500 mm (31.5 x 15.7 x 19.7 in). The listed build rate is up to 171 cm³/h.
On a plate this size the lasers have to share the area, and the listed software reflects that: the SLM Build Processor with MultiBeam zone management. How the zones overlap, and how a part that straddles two of them is stitched, is worth asking about for any large single part. Gas flow is listed as bidirectional, high-velocity and laminar, which matters more as a plate gets longer because fume has further to travel before it leaves the melt area.
Powder logistics are built in. The listed figures give 185 kg of integrated powder storage, with automated powder management and recoating. The process runs under argon or nitrogen at an oxygen level below 0.1%, with layers of 20 – 90 µm, a focus diameter of 80 – 120 µm and scan speeds up to 10.0 m/s. Listed materials are Ti6Al4V, Inconel 718/625, AlSi10Mg, Stainless Steel 316L, Hastelloy X, Maraging Steel and CobaltChrome.
This is a big installation. With its powder station the machine measures 8,900 x 4,100 x 3,400 mm, and the listed maximum power consumption is 35 kW. The SLM 800 has the same 4 × 700 W laser power and weighs approx. 8,500 kg. No weight is listed for the 800 Quad, so confirm floor loading for the specific machine.

Strengths & Limitations
Strengths
- Listed 800 x 400 x 500 mm (31.5 x 15.7 x 19.7 in) build volume with four 700 W Yb-fiber lasers
- 185 kg of integrated powder storage with automated powder management and recoating
- MultiBeam zone management in the SLM Build Processor software
- Bidirectional high-velocity laminar gas flow
- Oxygen level listed at below 0.1%, with argon or nitrogen as the inert gas
Limitations
- Listed maximum power consumption of 35 kW
- Occupies 8,900 x 4,100 x 3,400 mm with the powder station
- The listed build rate of up to 171 cm³/h has to cover a large plate, so full builds run long
- No machine weight is listed

Frequently Asked Questions
01
The listed build volume is 800 x 400 x 500 mm (31.5 x 15.7 x 19.7 in). Confirm it against the documentation of the individual machine before committing a large part, since the envelope decides everything else about the job.
02
The listed figures give 185 kg of integrated powder storage, with automated powder management and recoating. Whether 185 kg covers a full-height build depends on the density of the alloy and how much of the volume is filled, so work that out per job.
03
8,900 x 4,100 x 3,400 mm including the powder station, with a listed maximum power consumption of 35 kW. No weight is listed. The 3,400 mm height needs checking against the building and against any crane used to place the machine.
04
Four Yb-fiber lasers, listed as 4 x 700 W, with a focus diameter of 80 – 120 µm and scan speeds up to 10.0 m/s. The software row lists MultiBeam zone management, which by its name deals with how the plate is divided between the beams. The listed build rate is up to 171 cm³/h.
