Selective Laser Sintering (SLS) 3D printing is a widely used Additive Manufacturing technology, ideal for producing industrial rated, end-use parts on demand
Below is a list of our standard materials for SLS 3D printing. To instantly compare material prices, upload your parts to our online platform
Well-suited for large production runs, without effecting quality
Parts are isotropic and have similar mechanical properties to moulded parts
Our materials perform at operating temperatures up to 171°C
Nylon PA12 has excellent chemical and weather resistance
Nylon PA12 is biocompatible certified & sterilisable
SLS 3D printing is well-suited for end-use applications, high performance prototyping, jigs, fixtures, tooling and low volume production runs
We operate a parallel costing structure for our SLS 3D printing service, where you simply upload your 3D files to our instant quote tool. We either charge a rate of £0.11 per CM3 bounding box or £0.61 per CM3 volume, whichever is cheapest. Plus we offer competitive price breaks for quantities from 2 to 1000+
Selective Laser Sintering doesn't require support structures because unsintered powder surrounds the parts during the printing process and is simply brushed / blasted away when post-processing the parts. SLS 3D printing can produce complex geometries (such as interlocking and moving parts, parts with interior compartments / channels) that are unsuitable for other additive manufacturing processes such as; FDM or SLA
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 (vapour smoothing)
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 Grey 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.
Dyeing We are specialists in dyeing Grey 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..
