An SLS printing service is well worth considering if you need durable parts with detailed designs. In this additive manufacturing process, a high-powered laser fuses powdered material together to build your part one layer at a time. This results in a strong, functional component that you can use for prototypes, as well as for end-use applications.
Here’s a closer look at how selective laser sintering can help you create strong, complex parts.
Powder bed fusion technology
SLS is a type of powder bed fusion technology. During the printing process, a laser selectively fuses fine thermoplastic polymer powder layer by layer until the finished part is complete.
You can choose SLS to make strong, functional components, since it uses materials with excellent mechanical properties.
Strong, durable material options
A good SLS printing service offers several material choices, with PA 12 (nylon) being one of the most commonly used. The material gives your part a great balance of strength with durability and affordability, as well as ease of processing.
If your project has more specific performance requirements, materials such as glass-filled PA 12 can increase stiffness and improve thermal performance. It may even provide better wear resistance.
No support structures needed
With SLS 3D printing, you don’t need to design support structures for overhangs and complex features to keep them stable during production. Your part stays surrounded by unsintered powder throughout the entire process, and that powder naturally supports every section as it's being built.
This makes it possible to produce anything from intricate internal channels to interlocking parts and complex lattice structures — features that you’ll have difficulty producing or be impossible to achieve with many other manufacturing methods.
Reliable strength throughout the part
You’ll also appreciate the excellent layer bonding of SLS 3D printing.
Unlike some other 3D printing technologies where parts can be much weaker between layers, an SLS printing serviceproduces components with strength that's much more consistent in every direction. So, you can use it to make prototypes that you’ll subject to functional testing.
