Classic-car air ducting
Side-scoop air ducts with vents designed into the scoop and heat-set threaded inserts added for mounting, plus matching back plates.

SLS holds real weight, in shapes nothing else can make.
Selective Laser Sintering in tough nylon, from powder to finished part.
What It Is
Powder in. Parts out. That's SLS.
SLS fuses fine nylon powder into parts, with no build plate and no supports. That means complex, enclosed shapes, hundreds of parts per run, and strength in every direction. Every part is cleaned and inspected, ready for production use.

- Complex assemblies
- Functional prototypes
Every SLS part, made your way.
Design Freedom: No Supports
The powder supports every layer, so almost any shape is printable, even features sealed inside the part:
- Interlocking & captive parts: links and assemblies printed already joined.
- Enclosed hollows & channels: sealed voids and routed passages inside the part.
- Lattices & lightweighting: internal structures that cut weight, not strength.
- Print-in-place mechanisms: hinges and moving joints printed pre-assembled.
Strong in Every Direction
Fused solid all the way through, so parts hold up under real stress:
- Load-bearing parts: end-use components built to carry real loads.
- Snap fits & clips: housings and latches that click shut and hold, again and again.
- Tough, not brittle: thin sections flex under load and spring back instead of cracking.
Color & Finish
From raw nylon to a finished surface:
- Natural & dyed color: the classic soft, matte grey nylon, or dyed through in a range of colors, including a deep black that stays UV-stable long term.
- Blasted & polished: bead blasted for an even matte finish, or polished to a smooth, glossy surface.
- Painted: primed and painted in any color or finish.
Build In Your Branding
Your identity, built into the part, crisp and consistent from part to part:
- Logos & labels: your logo raised or recessed into the part, plus part numbers, instructions, and markings printed in.
- Branded products: products with your brand designed into the form.
- Surface patterns: textures and patterns worked into the surface.
Example Projects
Robotic parts
Ducting, clamps, and mounts for a robotic cell.
UV-stable black parts
Prototype parts dyed a deep black that holds its color in sunlight.
Advantage
Why SLS changes the game.
01
No Supports, No Limits
Complex geometry with nothing to remove and no support marks.
02
Strong in Every Direction
Fused solid all the way through, with nearly even strength in every direction. Durable nylon built for real end-use under load.
03
Nest for Volume
Pack the full build chamber in 3D; hundreds of parts per run.
04
Consistent & Repeatable
Uniform quality part to part, batch after batch.
05
Fine Detail
Crisp features, thin walls, and living hinges in a single part.
06
No Tooling
One part or thousands, no molds, the same workflow throughout.
SUSTAINABILITY
Strong parts, cleaner footprint.
Powder reuse
Un-fused powder is recovered and run again. About 70% of every build is reused powder, topped up with 30% fresh.
No support waste
The powder holds every part, so there are no support structures to print and throw away.
Nothing wasted
Nesting fills the chamber, so every build runs at its most efficient.
MADE WITH
Material: Powder
Run in-houseOur standard SLS material is Nylon 12 (PA12), a tough, chemical-resistant workhorse. When a part needs something different, we can run a full range of SLS powders, from flexible TPU to glass- and carbon-filled nylon.
