The Meltio M600 — Industrial Metal Additive Manufacturing, 24/7
The Meltio M600 is an industrial metal 3D printer based on LMD (Laser Metal Deposition) wire-laser technology. It melts standard metal wire using 9 blue diode lasers (450 nm, 1,000 W total) to deposit material layer by layer inside a fully inert chamber, ensuring optimal mechanical properties across a wide range of materials — stainless steels, titanium, nickel alloys, copper, aluminium, bronze, and precious metals (gold, silver).
Designed for continuous operation in industrial environments, the M600 is aimed at workshops looking to produce near-net-shape blanks and reduce their dependency on foundry lead times and raw stock inventories.
Blue laser technology for superior efficiency
Blue diode lasers (450 nm) offer a significantly higher absorption rate than traditional infrared lasers on highly thermally conductive metals such as copper or aluminium. The result: lower energy consumption per part, a more stable process, and superior material properties — particularly on difficult alloys.
The ideal complement to your CNC machining centres
The M600 rapidly produces near-net-shape blanks, eliminating foundry supply delays and minimising machined material waste. It integrates directly into existing manufacturing workflows thanks to its zero-point clamping system, compatible with standard workholding fixtures used on machining centres. Part transfer from the M600 to the CNC requires no re-referencing.
This complementarity delivers several concrete benefits:
Ecological
Less swarf, less wasted material, and an energy-efficient process driven by high-efficiency blue lasers.
Economic
Break free from traditional blank supply chains, reduce stock commitments and supplier lead times, and generate strong added value on small and medium production runs.
Logistical
Compact, wheeled machine that can be shipped in a container and deployed close to operational sites: mining platforms, vessels, defence bases, remote industrial facilities.
Built for industrial reliability
The M600 incorporates a full set of technologies focused on process stability and reduced operator intervention:
- Closed-loop control — Advanced sensors monitor the melt pool in real time and continuously modulate the laser and wire feed, ensuring part repeatability and consistency.
- Fibre-free deposition head — Eliminates the need for manual laser alignment before each print. An automated laser alignment system is available as an option for even faster calibration.
- Boosted wire feeding system — Designed for smooth, consistent wire delivery — a critical factor in melt pool stability.
- Long-endurance wire drums — Compatible with standard BS300 spools or external drums of 100+ kg for extended production runs without interruption.
- Oversized motion system — Linear servo motor axes with absolute encoders on all axes, engineered for maximum service life under intensive use.
- 3-stage filtration — Particulate and chemical filtration included as standard. The chamber continuously monitors O₂ and humidity levels to ensure process integrity, particularly on reactive materials such as titanium.
Options and accessories
- Hot Wire — Programmable power supply that preheats the wire before deposition, significantly increasing the deposition rate and reducing print times.
- Dual Wire — Sequential printing with two different materials and fast automatic wire switching. Ideal for bi-material structures or functionally differentiated zones.
- Quad Wire — Up to four materials in a single print, with automatic switching. Opens advanced possibilities for material gradients or multi-functional structures.
- Laser Alignment System — Automated calibration of the multi-laser deposition head before each print, with no manual intervention required.
- External wire drum — Connector for industrial spools of 100+ kg, enabling long production runs without interruption or reloading.
Software — Meltio Horizon
The M600 is driven by Meltio Horizon, Meltio’s proprietary 3-axis slicer, designed specifically for the wire-laser process. It offers predefined profiles covering a wide range of geometries and materials, simplifying setup for the operator and reducing print preparation time.
