Meltio M600

At Rapid Additive Manufacturing, we've invested in the Meltio M600 - one of the most advanced metal additive manufacturing systems in the world.

This technology allows us to produce fully dense, functional metal components directly from digital design data - faster, cleaner, and more efficiently than traditional machining or casting.

Whether you need prototypes, one-off components, or short production runs, we can now manufacture your parts in stainless steel, titanium, copper, nickel alloys, or aluminium - with exceptional accuracy, strength, and repeatability.

The Meltio M600 Advantage

The M600 is a next-generation metal 3D printer that uses multiple precision lasers to melt metal wire in a controlled inert atmosphere.

This process produces dense, high-integrity metal parts that match or exceed the properties of wrought material — but with far greater design freedom and efficiency.

Key technical benefits

Build volume: up to 300 × 400 × 600 mm
Material options: stainless steel, titanium, Inconel, aluminium, copper
Wire feedstock: safe, clean, and cost-effective (no hazardous powders)
Blue-laser technology: superior energy absorption for reflective metals
Integrated touch-probe and zero-point fixturing: precise, repeatable builds
Hybrid workflow: parts can be machined before, during, or after printing for ultra-accurate tolerances

Real-World Impact for Your Business

Lower part cost for small or complex components that would otherwise require multiple machining operations
Shorter lead times – ideal for urgent spares, R&D, or production bridging
Lightweight, consolidated designs – combine assemblies into a single printed part
On-demand flexibility – print when needed, where needed
Reduced carbon footprint – less material waste and transport compared to conventional machining

In industries like aerospace, motorsport, energy, and precision engineering, these advantages translate directly into time savings, cost reduction, and design innovation.

Is 3D Metal Printing as Good as Machining from Billet?

Machining from billet is the gold standard for accuracy and strength. The Meltio M600 doesn't replace that standard - it extends it. Using wire-laser metal deposition, we build fully dense, structural-grade metal directly from welding wire - the same certified feedstock used for machined components - and finish it conventionally.

The result: the same mechanical integrity and machinability as billet, with dramatically lower waste and faster turnaround.

1. True wrought-equivalent material properties

The Meltio M600 uses solid metal wire (not powder).
Each layer is fused by high-power lasers under controlled shielding gas, producing fully dense metal (>99.9 %) with minimal oxide inclusion or porosity.
Because the feedstock is commercial welding wire (17-4PH, 316L, Ti-6Al-4V, Inconel 625, tool steels, etc.), the printed chemistry is identical to wrought bar.
After standard stress-relief or heat treatment, tensile strength and hardness are typically within ±5 % of billet, and fatigue behaviour is comparable or better due to fine directional grain structure.

(Meltio publishes full mechanical test data confirming this equivalence — we can provide it on request.)

2. Fully machinable surfaces and tolerances

Parts are printed near-net shape, leaving 0.3–1.0 mm of stock for finishing.

Critical faces, bores and threads are then CNC-machined as normal, achieving:

Dimensional tolerances: ≤0.02–0.05 mm after finishing.
Surface finish: Ra ≤ 0.8 µm where required. Because the underlying structure is dense, tool engagement feels identical to wrought metal — no tearing or porosity.

3. Cleaner, safer, and more repeatable than powder-bed printing

Powder systems introduce handling risks, contamination potential, and higher running costs.

The Meltio M600's wire-fed deposition is closed, clean, and traceable:

No combustible dust.
100 % material utilisation (no sieving or recycling losses).
Every layer and melt pool is digitally monitored for consistency.

This gives superior process repeatability and straightforward material certification.

4. Dramatically lower waste and lead time

Machining from billet typically removes 70-90 % of the starting block. Wire-laser deposition builds only what's needed, cutting that waste to under 10 %. That means:

Material savings: often 60-80 % less raw stock.
Machining time reduced by up to 50 %.
Faster delivery - parts can go from CAD to printed blank overnight.

5. Freedom to design and repair intelligently

Because the process can add metal locally, you can:

Build features impossible to machine (internal channels, conformal cooling).
Repair or modify existing parts (tooling, dies, shafts, housings).
Combine printed and machined sections for hybrid manufacturing - using additive only where it adds value.

In summary

Parts produced on the Meltio M600 are chemically identical, mechanically equivalent, and fully machinable to the same standards as billet components — but with less waste, shorter lead times, and more design flexibility.

It's not a replacement for machining — it's a smarter first step.

You still finish-machine the surfaces that matter, but you start from a near-net printed blank instead of a solid block.

That's why leading aerospace, tooling, and precision engineering firms are now adopting wire-laser additive as the new normal for complex steel and titanium parts.

With the Meltio M600, it's the same metal — delivered more intelligently.

Why Choose Metal Additive Manufacturing?

Traditional machining starts with a solid block of metal and cuts away what you don't need.

The Meltio M600 does the opposite: it builds your part layer by layer, using precision laser-wire deposition.

The benefits for you are immediate and measurable:

No tooling or setup costs – perfect for one-offs, replacements, or low-volume production
Less waste, lower cost – we use only the material needed to make your part
Faster turnaround – from CAD file to metal component in days, not weeks
Freedom of design – internal channels, lightweight lattices, and complex shapes that machining can't produce
Fully dense, weldable and machinable parts – same performance as conventional metal, but made smarter
Reduced supply-chain dependency – parts can be manufactured on-demand, without relying on tooling lead times or stockholding
