Cost optimization, improved productivity, high definition printing, great freedom of design… these are some of the advantages of SLS (selective laser sintering) 3D printing. But, did you know that, by working with laser sintering printing equipment of the “open” type, Solaxis provides great freedom in the choice of materials used? This opens the door to the production of various types of parts, regardless of the sector of activity. Discover the properties of the materials that can be used for SLS 3D printing and start planning the production of your next parts!
Although many materials can be used for designing parts with SLS 3D printing, all have a common characteristic: they are easily shaped. Through systematization, the use of the following thermoplastics makes it possible to print parts with complex geometries, in a reproducible manner, whether it is about designing a prototype or answering production challenges.
A common thermoplastic used in injection molding, polypropylene is also a material of choice for SLS 3D printing. In fact, it stands out for its characteristics:
Thanks to its properties, polypropylene is a great material for manufacturing parts such as tools or industrial equipment, ventilation ducts or containers dedicated to the storage of various products, especially chemicals. This material works perfectly for hinges and clips, economical and functional prototypes.
At Solaxis, we print various parts in polypropylene, especially for the healthcare, electronics, automotive, and specialized transport sectors.
Nylon PA 11, a popular thermoplastic for short and medium series, makes it possible to design parts manufactured by SLS 3D printing with the following specificities:
Nylon PA 11 is therefore recommended for the design of critical parts, that is those frequently subjected to significant physical stresses. We prefer this material for the SLS 3D printing of medical equipment, automotive parts, medical orthotics, or various components used in the defence and security sector. This thermoplastic is effective for functional prototypes, replacement parts, and low-volume production that can be subjected to average loads.
Loaded with carbon fiber, Nylon PA 11 CF gives SLS-printed parts exceptional mechanical properties:
Nylon PA 11 CF is an excellent material for manufacturing parts that must present outstanding rigidity and solidity. Among others, we take advantage of the properties of this thermoplastic when it comes to designing automobile parts, light structure components, replacement parts for metal components, partially electrically conductive parts using SLS additive manufacturing.
Although Nylon PA 11 ESD obviously has characteristics similar to PA 11 Nylon (high tensile strength, important elongation), it also stands out for its specific properties:
Thus, this thermoplastic offers a multitude of possibilities for the electronics sector. To this end, in recent months, we have also completed various mandates focused on SLS 3D printing of electronic casings. ESD-safe materials, such as PA 11 ESD, are mainly used in electronics manufacturing, where thousands of electronic components are produced every day, requiring various components, jigs, tooling and custom fixtures.
SLS 3D printing allows the use of many materials with various characteristics. The manufactured parts can therefore meet mechanical, physical and/or aesthetic requirements as well. As a result, SLS 3D printing finds its place in different sectors of activity.
