Question 1

What is SLS 3D printing?

Accepted Answer

SLS, or selective laser sintering, is an additive manufacturing process in which a laser fuses polymer powder layer by layer into a three-dimensional part. The process generally requires no additional support structures, which makes complex geometries and functional components possible.

Question 2

What is SLS 3D printing used for?

Accepted Answer

SLS is used for functional prototypes, technical components, housings, brackets, production aids, spare parts, small batches and certain end-use products.

Question 3

What is the difference between SLS, FDM and SLA 3D printing?

Accepted Answer

In SLS a laser fuses polymer powder into a solid polyamide part with good mechanical properties and high toughness. FDM builds parts by depositing molten filament and suits simpler, lower-cost models. SLA cures liquid resin and achieves a very smooth surface with fine detail, which makes it a common choice for visual models. SLS generally needs no support structures, so it particularly suits complex geometries and functional parts that carry mechanical load.

Question 4

When is SLS a better choice than injection moulding or CNC machining?

Accepted Answer

SLS generally makes sense at lower quantities, for complex geometries, and while a design is still changing, because it needs no mould. Injection moulding becomes more economical at higher volumes, once the tooling investment is spread across many parts. CNC machining suits cases needing very tight tolerances or materials SLS cannot produce. We assess the crossover point against part size, geometry and quantity.

Question 5

Can SLS also produce end-use parts?

Accepted Answer

Yes. With the right design, material and application requirements, SLS is also used for small batches and certain end-use functional parts, with no conventional production tooling.

Question 6

What files do you need for a quote?

Accepted Answer

We need a suitable 3D model to produce a part. For a quote you can upload a supported CAD or mesh format, for example STEP or STL. For unusual formats, please check compatibility before submitting.

Question 7

Where are you located and where do you deliver?

Accepted Answer

Our production is in Hrastnik, Slovenia, where parts are built, finished and prepared for dispatch. We deliver across Slovenia and to European Union countries. The delivery date is confirmed together with the quote.
