SLS
no supports, free geometry
Selective Laser Sintering. A CO₂ laser fuses nylon powder layer by layer, and the unfused powder cradles every overhang — so geometry is free, supports don’t exist, and whole interlocking mechanisms print pre-assembled.
PRINTS ITS OWN SCAFFOLDING.

01 Why use it
the good bits
- Total design freedom: the powder bed is the support, so undercuts, lattices and internal channels cost nothing extra.
- Print assemblies pre-assembled: hinges, chains and ball joints come out of the machine moving.
- Tough, proven nylon parts with decades of production heritage.
- Dense nesting: pack the build volume in 3D for efficient short runs.
- A natural sibling to MJF: we route your part to whichever bed wins on cost and finish.
02 Ideal volumes
how many?
- 1–5,000 parts: functional prototypes through short-run production.
- Best for one-piece mechanisms and complex ducting.
- For higher volume or finer grain, MJF usually takes over; for cosmetic surfaces, SLA.
