Today, Selective Laser Sintering (SLS) provides higher performance than filament deposition for additive manufacturing, or 3D printing. The latter, a cheaper technology that tends to be used for personal 3D printers, presents difficulties regarding adhesion between layers.
“This is where SLS proves to be a game changer, because it enables us to maintain adhesion between all layers and mechanical performance is superior,” says Elodie Seignobos, technical leader for the Sinterline project at Technyl®.
The advantage of using SLS is that you can produce a small number of parts cheaper than injection moulding and with more design freedom. You can incubate all parts in one batch, control the heat, and the system is inert, making it better adapted to industrial applications.
This facilitates functional prototyping, which allows you to do several designs in one batch for comparison, both visually and by testing performance in a demanding environment. You can also modify designs from one production batch to the next.
In fact, because the product performance is close to injection moulding, 3D printing can be used to produce parts on demand, eliminating the need to store spares.
The advantage of using Technyl® powders for SLS is that, with our material, you can use it in more demanding environments and it is easy to process. Technyl® PA6 powder, for example, is better adapted to applications requiring a high degree of stiffness, strength and heat resistance.
“Our product is particularly popular in automotive prototyping applications,” says Seignobos. “We get good customer feedback on the ability to control temperature and processability using PA6. Our powder is well adapted, and the parts obtained are of high quality, thanks to improvements made in the latest 3D printers, which are better adapted for heat regulation.”
