SLS 3D Printing Overview
Industrial SLS 3D printing for
strong, functional parts
in Nylon and TPU.
No support structures are required, enabling efficient production of With
complex geometries and small batches.
Strong • Flexible • Accurate • Cost-Effective
Production Specifications
SLA Surface Finishing Options
Deburr / As-Printed
Deburring is our standard finish. Parts cleaned of loose powder and sharp edges.
PA Black Dye
Parts cleaned of loose powder and sharp edges. Appears more grey to dark grey rather than deep black.
PA Colour Dye
Fastest and most cost-effective way to colour white SLS parts to different Pantone/RAL colours.
PA Black (Deburr)
Parts cleaned of loose powder and sharp edges. Appears more grey to dark grey rather than deep black.
PA Black (Smooth)
Smooth finish may result in a lighter grey appearance while improving surface uniformity.
PA12 GF Deburr
Parts cleaned of loose powder and sharp edges. Notably rougher and more grainy than unfilled PA12.
PA12 GF Black Dye
Glass-filled additives makes achieving deep black colour difficult. Expect colour variations.
PA12 GF Smooth
Smoothing reduces surface roughness. Residual texture may remain due to glass-filled additive.
TPU Polishing
TPU parts can be chemical polished to produce a smoother, more glossy surface finish.
TPU White (Deburr)
Parts cleaned of loose powder. Leaves a natural white and slightly granular matte surface.
TPU Black (Deburr)
Parts cleaned of loose powder. Leaves a natural white and slightly granular matte surface.
PA White (Vapour Smoothed)
Smooths and seals the surface and enhances elongation at break and fatigue resistance. Ideal for parts with intricate details.
PA Black (Sand Smoothed)
Smooths the surface and may result in a lighter grey appearance while improving surface uniformity. Some graininess may remain.
PA Black (Vapour Smoothed)
Smooths and seals the surface and enhances elongation at break and fatigue resistance. Can result in a high gloss finish.
Advantage and Drawbacks of Accuro Rapid SLS printing
Advantages of SLS
No Support Structures: Unsintered powder naturally supports complex geometries.
Wide Material Range: Nylon, glass-filled nylon, TPU, PEEK and other engineering powders available.
Good Mechanical Performance: High strength & toughness for functional end-use parts.
Limitations of SLS
Rough Surface:Grainy as-printed surface, blasting/polishing required for smoothness.
Limited Fine Features:Poorer micro-detail resolution compared to SLA.
Powder Cleanup Required:Residual loose powder needs removal during post-processing.
Design Guidelines for SLS
To achieve high dimensional accuracy, reduce warping and successful prints, it is important that you design for the process. See the SLS design guidelines below.
