SLS Prototyping for Complex Designs

When it comes to developing prototypes with intricate geometries, functional strength, and durable materials, Selective Laser Sintering (SLS) stands out as an exceptional 3D printing technology. This process enables engineers and designers to create detailed, high-performance parts without the limitations of traditional manufacturing.

Why Choose SLS for Complex Prototypes?

SLS is an additive manufacturing technique that uses a high-powered laser to fuse powdered material layer by layer. One of its biggest advantages is that it doesn’t require support structures, making it an excellent choice for complex and self-supporting geometries that would be challenging or impossible with CNC machining or injection moulding.

Key Advantages of SLS

• Design Freedom: Intricate lattice structures, organic shapes, and internal channels can be printed with ease.
• Strong and Functional Parts: SLS produces durable components suitable for functional testing and end-use applications.
• Efficient for Low-Volume Production: Multiple parts can be arranged within a single build to optimise production costs.
• Fast Turnaround: Since no tooling is needed, SLS allows for quick prototyping and iteration

Common Applications of SLS Prototyping

SLS is widely used across various industries where complexity, strength, and performance are critical:

• Aerospace & Automotive: Strong, lightweight components, such as brackets and enclosures, that need to withstand mechanical stress.
• Medical & Healthcare: Custom prosthetics, orthotics, and medical devices designed to fit individual patients.
• Consumer Products & Electronics: Detailed housings, ergonomic grips, and snap-fit parts ideal for usability testing.
• Robotics & Industrial Equipment: Functional prototypes with integrated hinges, interlocking features, and durable materials.

The Benefits of Matrix PA12 CR

We use Matrix PA12 CR, a sustainable carbon-reduced PA12 material, to enhance the performance of SLS parts while reducing environmental impact. This material offers:

• High strength and durability for robust prototypes.
• Good chemical resistance, making it suitable for industrial applications.
• A reduced carbon footprint compared to standard PA12 options.

SLS Vapour Smoothing

For projects that need a refined finish, our vapour smoothing process enhances the surface quality of SLS parts. This finishing process chemically smooths the outer layer, reducing surface roughness while maintaining part accuracy and mechanical properties.

Key Benefits of Vapour Smoothing

• Improved Aesthetics: Produces a smooth, semi-gloss finish, ideal for visible or customer-facing components.
• Enhanced Mechanical Performance: Helps reduce friction and wear, making parts more durable for moving assemblies.
• Sealed Surfaces: Reduces porosity, which can improve resistance to moisture, chemicals, and bacteria.

Vapour smoothing is particularly beneficial for functional prototypes and end-use parts, ensuring they not only perform well but also look and feel refined.
