SLS (Selective Laser Sintering) is a powder-based 3D printing process that uses a laser to fuse layers of nylon material together to create functional prototypes and production parts. It is well-suited to complex geometries, lightweight structures and parts that need strength and durability.

SLS is widely used for functional prototypes, jigs and fixtures, and end-use parts. Its ability to produce complex shapes without the need for support structures makes it ideal for lightweight components, housings, enclosures and assemblies. Because SLS parts are strong and durable, the process is also well-suited to low volume production runs.

Absolutely. SLS parts possess mechanical properties suitable for end-use applications, including high strength, durability, and thermal resistance. They are often used in functional components, housings, and assemblies that require long-term performance.

SLS vs. SLA: While SLA offers superior surface finish and detail, SLS provides better mechanical properties and doesn’t require support structures.

SLS vs. DLP: DLP is faster for small parts with fine details, but SLS is more suitable for larger, functional parts with complex geometries.

SLS is widely used across various industries, including:

• Automotive: For prototyping and producing durable components.
• Medical: Creating custom prosthetics and anatomical models.
• Consumer Goods: Manufacturing complex and customized products.
• Aerospace: Producing lightweight and strong parts for aircraft and spacecraft.

SLS commonly utilises thermoplastic polymers like Nylon 12 (PA12), known for its strength, durability, and thermal resistance.

We offer Matrix PA12 CR – a carbon reduced nylon. To learn more about Matrix PA12 CR, visit our Materials Datasheets page.

SLS is very versatile, but we recommend a minimum wall thickness of 0.7 mm for rigid parts and 1 mm for larger components. Features such as snap-fits, clips and living hinges are possible, but it’s always best to check your design with our team if you’re unsure. We can advise on adjustments to optimise strength, detail and finish.

We offer a range of production speeds to suit your project needs. SLS 3D printed parts can be delivered via our Overnight service, or you can choose from 3, 7, or 12 working day turnaround options depending on your timescales and budget.

Yes. Our online Matrix system allows you to upload your files, get an instant quote and place your order directly for SLS 3D printed parts (as well as for SLA and DLP parts). You can also select your required production speed and finishing options, making it quick and simple to manage your projects.
