SLM, or Selective Laser Melting, is a metal 3D printing process that uses a high power fiber laser to fully melt fine metal powder layer by layer, producing solid, fully dense parts that rival cast or machined metal in strength and finish. At Fabit, SLM is one of the pillars of our in house production. It lets us turn a client sketch into a genuine metal award without moulds, tooling, or the compromises of mass manufacturing. For a high end trophy or a corporate recognition piece that has to feel substantial in the hand and last for decades, SLM offers a level of geometric freedom and material integrity that traditional methods simply cannot match.
How Selective Laser Melting actually works
The process begins with a bed of metal powder, often only twenty to sixty micrometres deep per layer. A laser traces the exact cross section of your trophy across that powder, delivering enough energy to melt the particles completely and fuse them to the layer below. The build platform then lowers by one layer thickness, a recoater blade spreads fresh powder, and the cycle repeats. Thousands of these micro layers accumulate into a finished three dimensional object. Because the metal is fully melted rather than merely bonded, the resulting part is dense, homogeneous, and mechanically sound.
Everything happens inside a sealed chamber flooded with inert gas, usually argon or nitrogen, to prevent oxidation at the moment of melting. This controlled atmosphere is one reason SLM parts show such clean metallurgy. For the reflective, jewel like surfaces our clients expect on a premium award, that purity matters enormously.
Why SLM suits premium trophies and awards
A recognition piece is not a functional bracket hidden inside a machine. It sits on a desk, a mantelpiece, or a stage, and it is looked at closely. SLM answers that scrutiny in several ways. It renders crisp logos, fine lettering, and delicate lattice structures that would be impossible to cast. It produces genuine metal weight, so the object carries the gravitas a serious award should. And because there is no mould, every piece can be different, which is ideal for personalised names, dates, or one off commissions.
We frequently pair SLM with hand finishing. The printed part comes off the platform with a raw, slightly matte texture, and our craftspeople then polish, brush, or coat it to the exact look the client wants. This marriage of digital precision and human craft is the heart of what we do.
Materials we run through SLM
SLM works with a wide family of metal powders. The most common choices for awards include stainless steel for durability and a bright polish, aluminium alloys for lightweight yet rigid pieces, titanium for a premium aerospace association, and precious or precious plated finishes for the most exclusive commissions. Each alloy behaves differently under the laser, and part of our expertise lies in tuning laser power, scan speed, and layer thickness for the specific material and geometry. You can explore the full range on our materials overview.
SLM compared with other metal processes
SLM is a form of powder bed fusion, the same broad family as EBM, or Electron Beam Melting. The key difference is the energy source. SLM uses a laser and works in an inert gas atmosphere, while EBM uses an electron beam in a vacuum and typically runs hotter. SLM generally delivers finer surface detail and tighter feature resolution, which is why it is our preference for intricate award geometry. Compared with binder jetting, which glues powder together and requires a later sintering step, SLM produces a fully dense part in a single thermal process, with no separate furnace cycle needed to reach final density.
Design considerations for SLM awards
- Overhangs and supports: steep overhangs need support structures that are removed afterwards, so we design with print orientation in mind to protect visible surfaces.
- Wall thickness: very thin walls can warp under thermal stress, so we specify minimum thicknesses that keep fine features stable.
- Internal channels: SLM can create hollow or lattice interiors that reduce weight without changing the outer form.
- Surface orientation: the face that matters most is oriented to minimise stair stepping and support scarring.
- Post processing allowance: we leave stock material where polishing or machining will follow.
The Fabit in house advantage
Because our SLM capability sits under our own roof in Antwerp, we control the entire journey from file to finished object. There is no outsourcing, no loss of quality between suppliers, and no waiting on a third party queue. That control is what lets us promise a response within twenty four hours and ship finished pieces worldwide. When a client sends an idea, our team can prototype, refine, and produce without the friction that fragmented supply chains introduce. See how this plays out across our custom trophy service.
From concept to finished piece
A typical SLM commission moves through digital design, a review of printability, the print itself, careful removal from the build plate, heat treatment where the alloy calls for it, support removal, and then the finishing that gives the piece its final character. Throughout, our advisory approach means we guide clients on what will look best and last longest, rather than simply printing whatever arrives. If you want to begin shaping a concept immediately, our online create tool is the fastest starting point.
Frequently asked questions
Is an SLM trophy solid metal? Yes. SLM fully melts the powder, so the finished award is dense metal throughout, not a coating over another material.
How detailed can SLM go? Feature resolution down to a fraction of a millimetre is achievable, which is why fine logos and lettering reproduce so cleanly.
Can each piece be unique? Absolutely. Since SLM needs no mould, personalising names, dates, or entire forms across a series costs no tooling and adds no delay.
How long does an SLM award take? Print time depends on size and complexity, but because everything is in house we respond to enquiries within twenty four hours and move quickly from there.
SLM is more than a manufacturing method for us. It is the technology that makes truly bespoke, museum quality metal recognition pieces possible, and it underpins the craft that defines every Fabit commission.
