Durable, High-Performance Parts with no need for Support Structures.

Selective Laser Sintering (SLS) is a trusted and highly versatile 3D printing technology, ideal for producing strong, functional prototypes and end-use parts with complex geometries. By using a laser to fuse powdered nylon materials layer by layer, SLS creates parts with excellent mechanical strength, heat and chemical resistance, and consistent performance under load.

At Paragon Rapid Technologies, we use SLS to produce parts that are both tough and accurate—perfect for mechanical assemblies, housings, brackets, ducting, and more. With no need for support structures, SLS allows for intricate designs, nested builds, and faster iterations, making it ideal for product development and low-volume production across sectors such as automotive, aerospace, industrial, and medical.

  • High-Strength Functional Parts SLS delivers robust, impact-resistant parts with excellent load-bearing and thermal performance—suitable for demanding real-world applications.
  • Freedom of Design With no need for support structures, complex internal geometries, interlocking parts, and enclosed assemblies can be printed in one build.
  • Efficient Batch Production SLS allows for densely packed build volumes, enabling multiple parts to be printed simultaneously—ideal for short production runs and rapid prototyping.
  • Reliable Nylon Materials Most commonly printed in PA12 or PA11, offering durability, flexibility, chemical resistance, and long-term stability for both prototyping and end-use applications.

Produce strong, accurate nylon parts for functional prototypes and low-volume production.

Selective Laser Sintering (SLS) is an advanced 3D printing technology that produces durable, high-performance parts without the need for support structures. Using a high-powered laser to fuse layers of nylon powder, SLS creates complex, functional components with excellent mechanical properties and dimensional accuracy. At Paragon Rapid Technologies, our SLS 3D printing service is trusted by engineers and manufacturers across the automotive, aerospace, medical, industrial and consumer sectors for rapid prototyping, bridge manufacturing and end-use production parts.

High-Strength Nylon Parts

SLS is ideal for manufacturing functional prototypes and production-ready components that can withstand demanding environments. Parts are manufactured using engineering-grade nylon materials, including PA12 and PA11, delivering excellent strength, impact resistance, heat resistance and chemical resistance. Whether you’re validating a new product design or producing end-use components, SLS provides reliable performance without compromising on quality.

Design Freedom Without Support Structures

Unlike many additive manufacturing technologies, SLS requires no support structures during the printing process. This allows engineers to create intricate geometries, internal channels, lattice structures, enclosed assemblies and moving parts in a single build. Greater design freedom means fewer manufacturing constraints and reduced post-processing, helping accelerate product development.
