How it works

How metal 3D printing with SLM works

Selective Laser Melting builds a part from the bottom up, one thin layer of metal powder at a time, straight from your 3D file.

  1. Prepare the fileYour CAD model is sliced into layers and parts are laid out on the plate. MonoSlice software automates this.
  2. Spread powderA flexible soft blade spreads a thin, even layer of metal powder across the build plate.
  3. Melt the layerThe laser scans the cross-section and melts the powder, which freezes again in milliseconds. Nitrogen or argon keeps oxygen away.
  4. Lower and repeatThe plate drops by one layer and the cycle repeats until the part is finished.
  5. FinishHeat treatment, removal from the plate, support removal and machining or polishing.

FAQ

Frequently asked questions

What is a metal 3D printer?

A metal 3D printer builds parts directly from a 3D file by melting thin layers of metal powder with a laser. No mould or cutting tool is needed.

Which metal 3D printers does Monoline offer?

Six EchoMetal SLM models: DeskMLR H1, MLR-M140C, MLR-M220, MLR-M300, MLR-M420 and MLR-M800, from a Φ100 × 80 mm desktop build volume up to 650 × 650 × 800 mm.

What materials can I print?

Depending on the model: stainless steel, tool steel, titanium alloy, pure titanium, superalloy, aluminium alloy, copper alloy, cobalt-chromium alloy and high-entropy alloy.

Which printer is best for dental or research work?

The DeskMLR H1 and MLR-M140C are aimed at education, scientific research and dentistry, and the MLR-M220 at medical, dental and prototyping work.

Which printer is best for production parts?

The MLR-M300, MLR-M420 and MLR-M800 are industrial machines for mould, electronics and aerospace parts, with dual lasers, 8 lasers, or 4, 6 or 8 lasers on the M800.

How fast does a metal 3D printer build?

Up to 100 cm³/h on the MLR-M300 and up to 240 cm³/h on the MLR-M420 and MLR-M800. Real speed depends on material, layer thickness and part geometry.
