Powder bed fusion is a family of 3D printing processes that build parts by spreading thin layers of powder and using a focused energy source, a laser or an electron beam, to fuse selected regions of each layer together, stacking those fused cross sections into a complete, dense object. It is the technological heart of Fabit’s award production. When we speak of Selective Laser Melting and Electron Beam Melting, we are naming specific members of the powder bed fusion family. Understanding the family as a whole explains why this approach delivers the detail, density, and design freedom that a truly premium recognition piece requires.
How powder bed fusion works
Every powder bed fusion process follows the same elegant logic. A recoater spreads a very thin, even layer of powder across a build platform. An energy source then scans the exact cross section of the part, fusing the powder in those regions to itself and to the layer beneath. The platform lowers by one layer thickness, fresh powder is spread, and the cycle repeats, often thousands of times, until the finished object emerges from the powder bed. Surrounding unfused powder supports the part as it builds and is recovered and reused afterward.
The energy source is what distinguishes the variants. A laser working in an inert gas atmosphere defines laser powder bed fusion, the category that includes SLM. An electron beam working in a vacuum defines electron beam powder bed fusion, which is EBM. Both fully melt the powder to produce dense metal, and both share the layer by layer discipline that gives the family its precision.
Why powder bed fusion suits premium awards
Powder bed fusion is our chosen path for fine metal awards for compelling reasons. It resolves extraordinarily fine features, so logos, names, dates, and delicate lattice structures reproduce with crisp fidelity. It produces fully dense metal, so the finished piece carries real weight and lasting strength. And because the part is defined purely by a digital file, every single object can differ from the last, which makes personalisation effortless and one off commissions entirely practical.
These qualities align exactly with what a recognition piece must be. It is examined closely, handled, displayed, and expected to endure. Powder bed fusion answers all of those demands in one process, and the hand finishing our craftspeople add afterward elevates the result to museum quality.
The powder bed fusion family
- SLM, Selective Laser Melting: a laser fully melts metal powder in inert gas, giving fine detail and dense parts, our default for intricate awards.
- EBM, Electron Beam Melting: an electron beam melts powder in a vacuum, favouring low stress titanium and thick sections.
- Laser sintering variants: related processes that fuse polymer or metal powders, sometimes without full melting.
You can see the finished materials this family enables on our materials overview, from stainless steel to titanium and premium finishes.
Powder bed fusion compared with other methods
Against binder jetting, powder bed fusion melts rather than glues, so it reaches full density in a single thermal process without a separate sintering step, and it delivers a finer surface. Against directed energy deposition, powder bed fusion works in a controlled bed rather than feeding material through a moving nozzle, so it achieves far finer detail, though it cannot build the very large parts DED handles. Against material jetting, powder bed fusion produces genuine dense metal rather than photopolymer, so the result is a lasting object rather than a visual model. Each comparison points to the same conclusion for our work, that powder bed fusion is the right foundation for durable, detailed metal awards.
Design considerations
Designing for powder bed fusion rewards a few disciplines. Overhangs may need support structures, so we orient the part to protect its most important faces. Minimum wall thicknesses keep fine features stable against thermal stress. Internal lattices can reduce weight without altering the visible form. And we leave allowance where polishing or machining will follow. Because we handle design and production together in house, these decisions are made holistically rather than passed between disconnected suppliers.
The Fabit in house advantage
Owning our powder bed fusion capability in Antwerp is what lets Fabit promise both quality and speed. There is no outsourcing, no quality drift between vendors, and no waiting in someone else’s queue. We can prototype, refine, produce, and finish under one roof, respond to enquiries within twenty four hours, and ship completed pieces worldwide. This integration is the practical engine behind our custom trophy service.

A powder bed fusion award begins with an idea, which our team then shapes into a printable, beautiful, and durable object. To start that conversation immediately, open our online create tool and begin bringing your concept to life.
Frequently asked questions
Is powder bed fusion the same as SLM? SLM is one member of the powder bed fusion family, specifically the laser based, fully melting variant we favour for detailed awards.
Does powder bed fusion make solid metal parts? Yes. The melting variants fully fuse the powder, producing dense metal throughout.
Can each piece be personalised? Yes. Since the part is defined by a digital file with no mould, personalising every object costs no tooling and adds no delay.
What happens to the leftover powder? Unfused powder supports the part during the build and is recovered and reused afterward.
Powder bed fusion is the quiet, precise foundation beneath every fine metal award we make, and understanding it explains why the results feel so substantial and so exact.
