What is SLS?
Selective Laser Sintering (SLS) is a powder-based 3D printing technology. It makes use of a high powered laser that selectively scans a thin layer of powder and sinters the small powdered plastic particles together to form 3D object, layer by layer.
Benefits of Industrial SLS 3D Printing
Unlike most other additive manufacturing technologies, SLS does not require any form of support as the leftover unsintered powder acts as self-supporting material. Thus, extremely complex geometries are made possible.
The technology is a great choice when 3D printing functional prototypes as SLS printed parts are robust and will not become brittle over time. In fact, the durability of parts created with SLS technology is on par with those produced through traditional manufacturing methods such as injection moulding.
In comparison to MJF, SLS also has more material options.
Benefits of GF & PA 12 in 3D Printing
When it comes to 3D printing materials, the synthetic thermoplastic known as Nylon (PA) is commonly used. Able to be 3D printed using SLS technology, industrial nylon SLS enables the creation of complex architecture models and prototypes that are strong, tough, and have good thermal loading capabilities.
- Glass Filled Nylon in 3D Printing
Glass filled nylon is a 3D printable nylon composite material. As glass filled nylon 3D printing consists of 30% glass fibers, it can be fabricated by SLS 3D printing technology to produce industrial parts with high strength and stiffness over standard nylon, simultaneously achieving low abrasive wear and complex geometries.
- PA 12 in 3D Printing
Like glass filled nylon, PA 12 is a solid material that does not require structural support. Compared to PA 11, PA 12 is a 3D printable nylon that possesses the suitable mechanical properties necessary for the creation of functional prototypes. There is a full range of other materials you can explore if you’re interested in PA12 3D printing. PA 2200, like PA 2201, PA 2241 FR, and more, are variants of polyamide 12. PA 2200 meets the industry standard for high-end 3D printing due to its strength, rigidity, and chemical resistance. An affordable material, PA 2200 SLS 3D printed parts are extremely versatile and are a high-performance alternative to other less durable plastics.
3D Printing Processes
Short for Fused Deposition Modeling, FDM is one of the most commonly adopted additive manufacturing technologies today due to its low cost and efficiency.
Great for products that require a smooth finish and high accuracy. SLA is also a popular choice for creating prototypes for clear parts, including bottles.
Capable of printing multiple materials from flexible to rigid in one part. 3D prints at a high speed, with extremely high accuracy and a smooth surface finish.
SLS is a powder-based 3D printing technology suitable for building parts that require high durability and complex geometries as it does not need any form of support.
Similar to SLS, Multi Jet Fusion also utilises powder to 3D print objects. One advantage is that parts produced by MJF are stronger and more precise compared to SLS.
