SLS 3D PRINTING

Selective Laser Sintering (SLS) is a widely used Additive Manufacturing technology and ideal for producing industrial rated, end-use parts on demand

TECHNICAL INFORMATION

We use Formlabs machinery for our SLS (Selective Laser Sintering) production. These top of the range industrial 3D printers are designed for controlled, consistent production of end-use parts. Using powder-based Nylon PA12 material, these machines use the latest technology in environmental control to ensure maximum dimensional stability (± 0.3%) and accuracy (lower limit ± 0.3 mm). 

Combined with our knowledge and advanced finishing techniques, we use the Fuse series machines to produce the best quality SLS 3D prints on the market. See our material properties below or download a data sheet.

SLS FREQUENTLY ASKED QUESTIONS

Selective Laser Sintering (SLS) works by curing powder based material, layer by layer building upon pre-determined geometry.

SLS is well-suited for end-use applications, jigs, fixtures and large scale production runs.

SLS requires no support material and is ideal for complex geometries with overhangs and undercuts.

We have a choice of Black & Grey colours for our PA12 Nylon material, with some colour options available upon request. We also offer media blasting and professional spray painting services. 

Yes, this is entirely possible. We have some tips on common finishing solutions:

Sanding
Try using wet & dry sandpaper of around 400 grit. The black paper can sometimes stain the parts so make sure to use lots of water and change over the paper regularly.

Painting
Our SLS prints come in white as standard, which is great for painting but they come with a powdery texture which needs to be sorted before painting. Always start with primer and sand a little before painting with acrylic paint. We would suggest taking advantage of the free vibro-polishing service before painting your part.

Dyeing
We are specialists in dyeing white SLS parts black, but there are many other colours out there that you can try out. We recommend using rit dye for synthetics and a pressure cooker, though a normal pot should work fine. There is an amazing academic paper on SLS Nylon dyeing from Goldsmiths University.

Glueing
Due to the powdery nature of Nylon prints, it requires a thicker glue to bond parts together. We recommend a 2 part epoxy resin like Araldite or a thick super glue like mitre glue. Standard superglue will not work well as it dries too quickly on the surface of the parts.

Our PA12 Nylon material is biocompatible and can be food-safe under certain conditions. We’re unable to certify it food-safe as SLS parts are porous and require specific post-processing to achieve that standard.

You can specify when placing our order your desired orientation using our order messaging system, otherwise our technical team will automatically orientate your part for you.

To reduce your part costs there are a number of options available. The best way to save money with SLS printing is by using 3D nesting. Geometry dependant, you can group multiple files together to get a cheaper price.
