A.I. Tony shares some design tips to enable designers to get the most from SLS 3D Printing.
What is SLS?
SLS is a 3D printing technology that is often used for prototyping parts that will ultimately be injection moulded in production.
What features can be made using SLS?
When end-use parts are produced with SLS, it’s possible to include features that can’t be injection moulded. These include features such as: internal voids, lattice structures, negative draught angles and hollow spaces.
Print ready-assembled parts using SLS
Another possibility is printing ready-assembled parts. There needs to be clearance for unsintered powder to be removed from between the parts, but it can be a useful technique for some assemblies, particularly if you need a hinge mechanism.
SLS parts can warp
Relatively large parts can be printed, but large flat surfaces or long slender parts can warp due to the thermal distortion during the cooling down of the build.
Watch our video ‘Can SLS parts warp?’ to learn how to minimise warpage.
What about living hinges?
Living hinges can be printed but the life of the hinge will be limited. Typically, it’s best to use off-the-shelf hinges to increase the part’s life.
Can threads be printed with SLS?
Both internal and external threads can also be printed, but it’s best to check with our production team to ensure we can print the desired feature.
