What Is SLS 3D Printing?

Selective Laser Sintering (SLS) is an industrial 3D printing process ideal for manufacturing end-use parts. In SLS 3D system, a laser selectively sinters polymer powder particles, fusing them together and building a part layer-by-layer. From SLS rapid prototyping to small-batch production, our SLS 3D printing facilities will allow you to produce highly accurate parts, with low cost and high quality comparable to injection molding.

SLS produces functional plastic parts with isotropic mechanical properties that can be used for detailed prototyping or end-use low-volume production.

SLS 3D Printing Design Guidelines

The following table summarizes the recommended and technically feasible values for the most common features encountered in 3D printed parts.

Feature	Recommended Size
Unsuported Walls	1mm(0.040")
Supported Walls	0.7mm(0.030")
Minimum Detail Size	0.25mm(0.010")
Minimum Hole Size	1.0mm(0.040")
Moving Parts	0.5mm(0.020")between moving surfaces
Assembly Clearance	0.4mm(0.016")between mating surfaces
Max Wall Thickness	20 mm (0.8''). Thicker parts must be hollowed with and at least two escape holes for powder removal with a min. diameter of 8 mm (0.3'').

Surface Finishing for 3D Printing

Surface finishing options for 3D printing provide a range of enhancements to the printed parts. Check out these customized finishing options and find one that suits your project.

Name	Description	Materail Compatibility	Color	Texture
Painting	Choose from a wide range of paints and coatings that can achieve the desired look and feel.	Plastics and metals	RAL or Pantone code	Gloss, semi-gloss, flat, metallic, textured
Polishing	Achieve a smooth and glossy surface finish through mechanical polishing techniques. This process removes layer lines and imperfections, resulting in a refined appearance.	Plastics (PLA, ABS)	Raw material	Smooth and glossy
Powder Coating	Apply a durable and protective powder coating to your 3D-printed part. This process involves electrostatic-ally applying a fine powder, which is then cured to create a tough and resistant finish	Metals (Alumium, stainless steel, steel)	Standard and custom options	Gloss or semi-gloss
Bead Blasting	Utilize bead blasting to achieve a uniform and textured surface finish. This process involves propelling small abrasive particles at the surface of the object.	Metals and plastics	N/A	Matte or satin-like
