WHAT IS SLS (SELECTIVE LASER SINTERING) ?

SLS 3D Printing services

Selective Laser Sintering (SLS) is a powder-bed fusion process where a high-power laser selectively fuses polymer powder layer by layer to form solid parts.

Why SLS for Additive Manufacturing ?

Industrial-Grade SLS Additive Manufacturing for Functional, Production-Ready Parts

At Protofy 3D, Our Selective Laser Sintering (SLS) 3D Printing Services deliver high-strength, isotropic polymer parts designed for functional prototyping, low-volume production, and end-use applications. Using industrial SLS systems and engineering thermoplastics, we manufacture complex geometries with excellent mechanical performance—without support structures and with consistent repeatability.

Built to support both engineering development and series production.

Production-Grade SLS Infrastructure

We operate industrial SLS systems designed for repeatability, dimensional stability, and batch efficiency.

Engineering-Grade SLS Materials

We support a range of SLS thermoplastics, including PA12 (Nylon 12), PA11, Glass-Filled Nylon.Custom material options available on request

SLS Materials We Offer

Selective Laser Sintering primarily uses high-performance nylon powders:

Note: Material selection is guided by load, environment, and surface requirements.

Applications of SLS 3D Printing

SLS delivers strong, accurate, and scalable polymer components for real-world applications.

Automotive Components – Ducts, brackets, covers, and lightweight structural parts
Aerospace & Defense ApplicationsInterior components, tooling, and functional prototypes
Jigs, Fixtures & Tooling Robust manufacturing aids with long service life
Medical & Wearable Devices Custom housings and ergonomic components

Result: high-performance SLS parts that scale seamlessly from prototype to production.

Design Freedom with SLS (DFAM)

Our engineers provide Design Support for SLS Manufacturing to ensure manufacturability and performance.

Support-Free Geometry Internal channels, undercuts, and complex assemblies print without support structures
Integrated FunctionalitySnap-fits, hinges, threads, and moving features built directly into the part
Complex Internal Structures Lattices, lightweight cores, and internal passages at no added cost
Optimized AssembliesMultiple components consolidated into a single printed part

Outcome: lighter, stronger, and more functional designs—ready for production with minimal post-processing.

SLS Quality Control & Process Discipline

Consistent SLS performance is achieved through tightly controlled processes, disciplined workflows, and rigorous quality checks across every build.

Powder Management Controlled refresh ratios and material traceability ensure stable sintering behavior
Machine Calibration Regular laser, optics, and thermal calibration for dimensional accuracy
Process Parameters Optimized laser power, scan strategy, and layer thickness
Post-Build Inspection Depowdering, dimensional checks, and surface quality validation

Result: reliable, high-precision repeatable, production-grade SLS parts with predictable quality and performance.

SLS for Production & Scalability

Selective Laser Sintering is designed for efficient scaling from development to repeat production—without the cost or delays of tooling.

Tool-Free Production Eliminate molds and fixtures, enabling rapid scale-up
High Build Density Optimized nesting lowers cost per part
Batch Consistency Repeatable quality across multiple builds
Parallel Manufacturing Multiple systems support higher volumes
Bridge & Series Production Ideal for low- to medium-volume manufacturing

Result: flexible, scalable SLS production with predictable cost, quality, and lead time.

SLS Surface Finishes & Post-Processing Options

Post-processing enhances the appearance, functionality, and integration of SLS parts for end-use and production applications.

As-Printed (Matte Finish) Uniform, slightly grainy texture typical of SLS parts
Bead Blasting Enhanced smoothness and consistent appearance
Dyeing (Black / Custom Colors) Improves aesthetics and UV resistance
Surface Sealing Reduces porosity and enhances durability
Tumbling & Smoothing For improved touch and cosmetic finish

Result: production-ready SLS parts with the required aesthetic and functional performance.

Validated SLS Manufacturing Capabilities for Enterprise Use

DESIGN VALIDATION TO PRODUCTION READY COMPONENTS

How to Design Parts for High-Performance SLS 3D Printing & Optimization Services

Design parts that fully exploit the power of SLS—complex geometries, superior strength, and consistent quality. Maintain consistent wall thickness, use smooth transitions and fillets to reduce stress, and design features robust enough to withstand depowdering. Allow proper clearances for assemblies, oversize critical holes for accuracy, and include powder escape paths in hollow parts.

Design principles to achieve strong, accurate, and production-ready SLS parts

Wall Thickness & Structural Stability

SLS allows thinner walls than many other 3D printing technologies due to powder-bed support.

Hole Sizes & Internal Channels

Powder removal and sintering behavior affect hole accuracy.

Tolerances & Dimensional Accuracy

SLS offers excellent repeatability for functional parts.

Hollow Parts & Powder Escape

Hollowing parts reduces material usage and cost.

Material-Specific Design Considerations

Most SLS parts are printed in nylon-based materials.

Post-Processing & Finishing Allowances

SLS parts are often bead blasted, dyed, coated, or machined.
