Custom nylon parts for functional testing, complex assemblies, and low-volume production.
TENGHUI provides selective laser sintering services to help you turn CAD designs into practical plastic components. Produce housings, brackets, ducts, and other complex parts without dedicated tooling, with support for material selection, design review, and finishing.
| Item | Project Considerations |
|---|---|
| Materials | PA12 and PA11, subject to grade availability |
| Part size | Reviewed against material, equipment, and usable build space |
| Dimensional requirements | Confirmed from your drawing and critical features |
| Wall thickness | Reviewed for strength, handling, and distortion risk |
| Surface appearance | Typically matte with a slightly textured finish |
| Lead time | Confirmed after file review and finishing selection |
Every SLS sintering build requires precise review of component geometry, orientation, and thermal balance to ensure structural integrity and tight tolerances.
• 2D Drawing Requirements: Please provide a 2D drawing for critical dimensions, fits, and inspection requirements.
• Geometry DFM Review: Large flat surfaces, thin features, and long components may require additional design review to prevent warping.
Selective laser sintering, or SLS, builds parts by selectively fusing polymer powder with a laser. Surrounding powder supports the part during printing, so separate support structures are generally unnecessary.
This makes SLS useful for shapes that are difficult to manufacture through conventional methods. Enclosed spaces and internal passages must still allow access for powder removal.
Choose your material based on stiffness, flexibility, operating conditions, and the way your part will be used.
A versatile option for general functional parts, offering a useful balance of strength, stiffness, and chemical resistance.
Typical Applications: Equipment housings, mounting brackets, ducts, covers, and assembly prototypes.
An option for applications that prioritize ductility and impact performance. Material grade and part design should be reviewed for features that flex or experience repeated loading.
Typical Applications: Clips, snap-fit components, protective parts, and flexible functional assemblies.
Material Specification Note: Material availability, colors, and grade-specific properties are confirmed during quotation. Please identify any temperature, chemical exposure, or certification requirements before ordering.
Accelerate product validation and bridge the gap to volume production with direct powder bed laser sintering without mold commitments.
Produce intricate components without investing in a mold. SLS supports design changes during development and provides a practical route to smaller production quantities.
Evaluate fit, assembly, and performance using engineering thermoplastics. Final suitability depends on the selected material, geometry, loading conditions, and environment.
Combine suitable features into one printed component to reduce assembly work and simplify your overall product design.
Order development parts or repeat batches without committing to injection-molding tooling. Pricing depends on part size, quantity, material, and finishing requirements.

Accessible surfaces and cavities are cleaned after printing[cite: 19]. Internal features should be designed to allow effective powder evacuation[cite: 19].
Create a more uniform black appearance for compatible nylon materials[cite: 19]. Surface texture and geometry can affect the final result[cite: 19].
Specify your target color and cosmetic requirements for review[cite: 19]. Surface preparation and coating thickness should be considered for mating features[cite: 19].
Smoothing may be available for selected materials to reduce surface texture[cite: 19]. Compatibility, dimensional effects, and appearance are reviewed by project[cite: 19].
Add metal threads where repeated fastening is required[cite: 19]. Insert type, hole design, and installation method should be planned before printing[cite: 19].
Engineering Note: Finishing availability depends on the material and geometry[cite: 19]. Sealing performance must be validated for the intended application[cite: 19].
Design consideration directly impacts sintered accuracy, thermal warp prevention, and depowdering ease. Follow these engineering practices to optimize your CAD models.
Add accessible openings to hollow sections. Multiple openings can improve cleaning access, while long or curved passages may require a different design.
Thin features can be fragile, and broad flat surfaces may distort. Consider ribs, curved transitions, and more consistent wall sections where practical.
Provide suitable gaps between mating or moving components. Clearances depend on feature size, orientation, surface finish, and cleaning access.
Mark important holes, sealing faces, mating surfaces, and tolerances on your drawing. This helps establish a realistic manufacturing and inspection plan.
Need DFM Guidance? Our engineers review CAD wall thicknesses, thermal stress risks, and depowdering routes prior to sintering.

Get a QuoteSLS is often selected for functional nylon components. SLA is often selected for fine details and cosmetic prototypes.
The best choice depends on mechanical requirements, surface appearance, and application.
Yes, where the selected material and process meet the application requirements.
Validate parts under representative operating conditions before production use.
Do not assume untreated SLS parts are watertight. Discuss the fluid, pressure, temperature, and required sealing performance before choosing a material or finish.
Yes, provided the geometry allows powder removal. Fully enclosed cavities retain powder, and narrow passages can be difficult to clean.
Please send your 3D CAD file, quantity, preferred material, finishing requirements, and delivery target.
Include a 2D drawing for critical dimensions and inspection requirements.
