What Makes Our SLM 3D Printing Different
Most SLM metal 3D printing Australia shops pair the process with a full parallel explanation of DMLS on the same page, which tells you they're really running one metal-printing operation with two names on it. We do run both processes, but we treat them as genuinely different tools for genuinely different jobs, and this page exists because SLM earns its own answer:
Full-density, near-wrought parts:
SLM fully melts the powder rather than sintering it, so the parts that come off our machines carry real mechanical strength, not just the shape of a metal part.
Structural metals through to precious metals:
stainless steel 420 and aluminium AlSi10Mg for industrial, structural work; brass, bronze, copper, silver, platinum and gold for precision or decorative pieces, all on the same process.
A manufacturability check before anything prints:
wall thickness, support strategy and tolerance risk get reviewed by an engineer, not discovered after the part's already built.
Custom SLM 3D printing Australia manufacturers rely on:
a single replacement part or a full production run, quoted and handled identically, no minimum order quantity.
5–6 working days
on most SLM jobs, depending on part size, geometry and material.
National, not city-bound:
quoted and shipped to every state and territory, with the same material access and process regardless of where you're based.
Private by default:
files and project details stay confidential, with standard purchase-order terms and no lock-in contract.
What Is SLM 3D Printing?
SLM (Selective Laser Melting) is a metal additive manufacturing process that builds solid parts directly from a CAD file: a high-powered laser fully melts fine metal powder, layer by layer, inside a sealed, oxygen-controlled chamber, fusing each layer into the one beneath it until the part is complete. Because the laser fully melts the powder rather than only fusing it at the edges, SLM parts come out dense and structurally sound, close to the mechanical properties of the same metal in wrought form, without a mould, a cutting tool, or a six-week lead time standing between the file and the finished part.
As an SLM 3D printing company Australia engineers and procurement teams turn to for selective laser melting Australia work, Quantix 3D Printing runs SLM 3D printing service jobs in stainless steel, aluminium and precious metals, quoted online and shipped Australia-wide.

How Selective Laser Melting Works
- 1
A thin layer of metal powder
rolls out across the build platform, sealed inside a chamber and purged with inert gas to keep oxygen out.
- 2
A laser traces the part's cross-section
into that layer, fully melting the powder along the path it follows.
- 3
The platform drops slightly
and a new layer of powder is spread on top.
- 4
The laser repeats the pass,
fusing the new layer to the one underneath, and the cycle continues until the full part exists inside the powder bed.
- 5
The part is removed, and any support structures and loose powder are cleared,
ready for finishing where the job calls for it.
The oxygen-controlled atmosphere matters more than it sounds: without it, metals like aluminium and stainless steel would oxidise mid-build and the part would come out brittle or porous. That controlled environment is a large part of why SLM machines, and SLM parts, cost more than plastic 3D printing.

SLM 3D Printing Materials We Work With
SLM at Quantix 3D Printing runs across two material groups: structural metals for industrial and engineering parts, and precious metals for precision or decorative work.
| Material | Typical Use | Max Build Size | Tolerance |
|---|---|---|---|
| Stainless Steel 420 | General industrial, structural parts | 760 × 390 × 390mm | ±0.2mm/100mm |
| Aluminium (AlSi10Mg) | Lightweighting: aerospace & automotive components | 270 × 220 × 320mm | ±0.2mm/100mm |
| Brass, Bronze, Copper, Silver, Platinum, Gold | Precision, decorative & bespoke components | Up to 89 × 89 × 100mm | ±0.2mm/100mm |
Need titanium, stainless steel 316L, nickel alloys or cobalt chrome? Those run on DMLS, our other metal process. See our full metal materials range → for the complete metal catalogue across both processes, or see all 45+ 3D printing materials → for plastics and resins too.
Is SLM the Same as DMLS?
No, though the two get used interchangeably online more often than they should. SLM fully melts the metal powder into a continuous structure; DMLS sinters the powder, fusing it without fully liquefying it. In practice that means SLM tends to suit larger, denser structural parts, while DMLS suits finer, more complex geometries in materials like titanium.
If your part could go either way, or you're not sure which one it needs, read the full SLM vs DMLS comparison on our metal 3D printing page →, or send us your file and we'll tell you directly, free, before you're quoted anything.
SLM 3D Printing Across Australian Industry
SLM suits applications where strength-to-weight, corrosion resistance or complex geometry matter more than tooling cost, across both structural and precision work:
Aerospace & Automotive:
lightweight aluminium AlSi10Mg brackets and structural components, and stainless steel 420 parts where strength-to-weight outweighs the cost of machining.
Engineering & Manufacturing:
jigs, fixtures, functional prototypes and structural parts with geometries that casting or machining can't produce in one piece.
Mining & Resources:
replacement parts for legacy or obsolete equipment, produced faster than sourcing through a traditional supply chain.
Jewellery & Precision Goods:
bespoke pieces and fine components in brass, bronze, copper, silver, platinum or gold, built directly from a CAD file rather than cast.
Robotics & Electronics:
precision brackets and lightweight structural components for prototypes and low-volume assemblies.
Whatever your industry, our SLM 3D printing service adapts to your material, tolerance and volume requirements, from a single part to a full production run.
What Drives SLM 3D Printing Cost in Australia
SLM 3D printing cost Australia splits into two very different tiers before anything else is factored in. Stainless steel 420 and aluminium AlSi10Mg sit in the structural tier: priced by part size, geometry and machine time, with the oxygen-controlled build environment built into that cost rather than added on top. Brass, bronze, copper, silver, platinum and gold sit in a different tier entirely: raw material cost dominates, and it isn't subtle, gold and platinum in particular cost dramatically more per gram than the powder feeding a structural build. Inside either tier, heavier support structures, post-processing and order quantity all move the final number, with per-part cost dropping as volume increases and no minimum required to get there. There's no published rate card, because none of that holds still long enough for one. Send your file for an online SLM 3D printing quote and get a number that's actually yours.

SLM 3D Printing: Frequently Asked Questions
What is SLM 3D printing?
SLM (Selective Laser Melting) is a metal additive manufacturing process that fully melts fine metal powder with a high-powered laser, layer by layer, inside an oxygen-controlled chamber, building a dense, solid part directly from a CAD file.
Is SLM the same as metal 3D printing in general?
Not exactly. Metal 3D printing is the broader category; SLM is one specific process within it. Quantix 3D Printing also runs DMLS, a related but different metal process, for materials like titanium.
What's the difference between SLM and DMLS?
SLM fully melts the metal powder into a continuous structure; DMLS sinters it without fully melting it. SLM tends to suit larger, denser structural parts, while DMLS suits finer, more complex geometries. See our metal 3D printing page for the full comparison.
What materials can you SLM print?
Stainless steel 420 and aluminium AlSi10Mg for structural and industrial parts, plus brass, bronze, copper, silver, platinum and gold for precision or decorative work. Titanium, stainless steel 316L, nickel alloys and cobalt chrome run on DMLS instead.
Will an SLM part actually hold up under load?
Yes. SLM fully melts the powder into a dense structure, with mechanical properties close to the same metal in wrought form, which is why it's used for structural aerospace, automotive and industrial engineering parts.
How much does SLM 3D printing cost?
It depends heavily on material: stainless steel and aluminium are priced by size, geometry and machine time, while precious metals are priced largely on raw material cost, which varies a great deal between, say, brass and gold. Upload your file for an exact figure.
How long does an SLM job take?
Most SLM jobs ship in 5–6 working days, though complex geometries can extend that; we'll confirm timing at quote stage.
What's the biggest part you can SLM print?
Up to 760 × 390 × 390mm in structural alloys like stainless steel 420; precious-metal builds are smaller, up to 89 × 89 × 100mm. Send your file and we'll confirm it fits before you commit to anything.
Is there an SLM 3D printing service near me?
Quantix 3D Printing runs as an online, Australia-wide service rather than a single local shopfront, so instead of searching for SLM 3D printing near me, you can send your file and have parts shipped to you anywhere in the country.
