Overview

The SLM 500 HL is listed as a four-laser Selective Laser Melting (SLM / LPBF) machine with a 500 x 280 x 365 mm (19.7 x 11.0 x 14.4 in) build volume and a choice of laser sets: 4 x 400 W or 4 x 700 W Yb-fiber lasers. The listed build rate of up to 171 cm³/h belongs to the quad 700 W configuration, and no rate is given for the 400 W set.

That choice is the first thing to pin down on any machine offered under this name. Each 700 W laser has 75% more power than a 400 W one, and the difference shows in how thick a layer can be melted at speed. The listed layer range is 20 – 90 µm, the focus diameter 70 – 120 µm and the scan speed up to 10.0 m/s. A machine fitted with the 400 W set should not be planned around the 171 cm³/h figure.

The listed figures also describe the installation. The machine measures 5,400 x 2,670 x 2,710 mm and draws up to 28 kW. It runs under argon or nitrogen with an oxygen level below 0.1%. Powder management is integrated, with automated overflow and return sieving, and the software row names the SLM Build Processor and real-time process monitoring. Listed materials are AlSi10Mg, Ti6Al4V, Inconel 718/625, Stainless Steel 316L, Hastelloy X, CobaltChrome and Tool Steel.

The SLM 500 Quad has the same 500 x 280 x 365 mm (19.7 x 11 x 14.4 in) build volume with 4 x 700 W fiber lasers, at approx. 4,200 kg (9,259 lb).

Strengths & Limitations

Strengths

Four Yb-fiber lasers, listed as 4 x 400 W or 4 x 700 W
Build rate of up to 171 cm³/h in the quad 700 W configuration
Integrated powder management with automated overflow and return sieving
Listed oxygen level below 0.1% under argon or nitrogen
Layer thickness from 20 – 90 µm with a 70 – 120 µm focus diameter

Limitations

The 171 cm³/h build rate applies to the 4 x 700 W configuration; no figure is listed for 4 x 400 W
Listed power consumption reaches 28 kW, so the electrical supply needs sizing for that peak
A 5,400 x 2,670 x 2,710 mm machine needs a large bay and a clear route in
The listed figures include no machine weight, so floor loading must be confirmed separately

Best For

Production parts that fit 500 x 280 x 365 mm (19.7 x 11.0 x 14.4 in) Nickel alloy work in Inconel 718/625 and Hastelloy X Shops that want powder overflow and return sieving automated inside the machine

Frequently Asked Questions

01 What laser options are listed for the SLM 500 HL?

Two: 4 x 400 W or 4 x 700 W, both Yb-fiber. Each 700 W laser has 75% more power than a 400 W one. The listed build rate of up to 171 cm³/h is tied to the quad 700 W configuration, so check which set a particular machine carries.

02 What is the build volume of the SLM 500 HL?

The listed build volume is 500 x 280 x 365 mm (19.7 x 11.0 x 14.4 in). That is the same envelope as the SLM 500 Quad, 500 x 280 x 365 mm (19.7 x 11 x 14.4 in), so part size does not separate the two.

03 What power and space does the SLM 500 HL need?

The listed maximum power consumption is 28 kW and the machine dimensions are 5,400 x 2,670 x 2,710 mm. Inert gas is argon or nitrogen. No weight, gas consumption or supply voltage is listed, so those have to be confirmed for the specific machine.

04 Which materials are listed for the SLM 500 HL?

AlSi10Mg, Ti6Al4V, Inconel 718/625, Stainless Steel 316L, Hastelloy X, CobaltChrome and Tool Steel, processed at layer thicknesses of 20 – 90 µm under argon or nitrogen with an oxygen level below 0.1%.
