SLS 3D Printing
SLS uses a laser to fuse polymer powder into strong components. Unfused powder supports the build, allowing complex geometries, internal channels, nested parts, and moving assemblies without conventional support structures.
Engineering nylons provide a useful balance of strength, impact resistance, temperature performance, and long-term durability for prototypes and production components.
Efficient build packing makes SLS particularly effective for mixed batches and repeat production where consistent function matters more than mould tooling.
340 × 340 × 600 mm build volume
Industrial capacity for individual large components or densely packed production batches.
No support structures
Powder supports the part during manufacture, enabling channels, lattices, and interlocking assemblies.
Durable engineering nylons
PA11, PA12, glass-filled, and carbon-filled options cover rigid and impact-resistant applications.
Production-ready consistency
Well suited to functional prototypes, bridge production, customised products, and repeat batches.

SLS 3D printing FAQs
Why does SLS not need supports?
The surrounding unfused powder supports overhangs and internal geometry throughout the build, so dedicated support structures are unnecessary.
Is SLS suitable for production?
Yes. SLS is widely used for repeatable end-use nylon parts and production batches without mould tooling.
What surface does SLS produce?
Raw SLS has a uniform, lightly textured matte surface. Dyeing, tumbling, smoothing, coating, and painting can be considered.
Can SLS print moving assemblies?
Yes. Properly designed clearances allow hinges, chains, interlocking parts, and selected mechanisms to be produced in one build.
How does SLS compare with FDM?
SLS offers more uniform mechanical behaviour and fewer geometric restrictions, while FDM is often faster and more economical for simple one-off parts.
