Selective Laser Sintering - Powder-based technology for strong, functional parts with complex geometries. No support structures required, enabling designs impossible with other methods.
Selective Laser Sintering (SLS) uses a high-powered laser to sinter powdered material (typically nylon) into solid structures. The surrounding unfused powder acts as support, allowing for complex geometries without the need for dedicated support structures.
High-performance nylon powders for demanding applications.
Excellent all-around material with good strength and flexibility.
More ductile than PA12, excellent fatigue resistance. Bio-based.
PA12 reinforced with glass beads for increased stiffness.
Rubber-like flexibility for gaskets, seals, and soft-touch parts.
Leverage SLS's unique capabilities with these guidelines.
Minimum: 0.7mm
Recommended: 1-2mm
Walls under 0.7mm may be too fragile to survive handling.
Overhangs: Fully supported by powder
Bridges: Unlimited
SLS's key advantage: design freely without worrying about support structures.
Min Hole: 1.5mm
Escape Holes: Required for enclosed voids
Enclosed cavities need 3.5mm+ escape holes to remove trapped powder.
Moving parts: 0.5mm minimum
Assemblies: 0.3mm
Print-in-place assemblies and hinges are possible with proper clearance.
Min Feature: 0.8mm
Text: 2mm height minimum
Small details can fill with powder. Design for slightly larger features.
Wall Thickness: 2-3mm
Save: Up to 50% cost
Hollow large parts to reduce weight and cost. Include powder escape holes.
SLS parts are produced in batches for efficiency. Standard lead time is 5-10 business days.
Rush orders subject to availability. SLS requires batch processing for efficiency.
