SLS 3D PRINTING

IN-HOUSE PROFESSIONAL SLS 3D PRINTING SERVICE, IDEAL FOR LOW-VOLUME PRODUCTION

Selective Laser Sintering (SLS) 3D printing is a widely used Additive Manufacturing technology, ideal for producing industrial rated, end-use parts on demand

TECHNICAL INFORMATION

We use Formlabs 3D Printers for our SLS 3D printing service. 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 3D prints on the market. See our material properties below or download a data sheet.

SLS 3D PRINTING - FREQUENTLY ASKED QUESTIONS

What applications can SLS 3D printing be used for?

SLS 3D printing is well-suited for end-use applications, high performance prototyping, jigs, fixtures, tooling and low volume production runs

How much does SLS 3D printing cost?

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+

Does SLS 3D printing need support material?

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

Are SLS 3D printed parts food-contact safe?

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)

Can I hand finish SLS 3D printed parts?

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..
