Industrial Additive Manufacturing
SLS 3D Printing Services
RapidPrintParts provides industrial Selective Laser Sintering (SLS) 3D printing services for manufacturing functional prototypes, complex durable nylon parts, and low-volume production components. Operating from our facility in Shenzhen, China, our engineering team focuses on producing industrial parts that are built to be used in demanding mechanical environments.
Overview of Selective Laser Sintering (SLS)
SLS is a powder-bed additive manufacturing process that uses a laser to sinter polymer powder layer by layer. Because the unfused powder acts as a natural support structure during the build process, SLS is highly effective for complex geometries, internal channels, and interlocking parts that would be difficult or uneconomical to produce with traditional manufacturing.
We operate 10 dedicated SLS machines in-house, allowing us to support everything from initial engineering validation builds to bridge production and low-volume end-use manufacturing.
Key Process Advantages
- 1 No support structures required for complex internal geometries
- 2 High design freedom for interlocking and moving parts
- 3 Excellent material properties for functional end-use components
- 4 Scalable from prototyping to low-volume production
SLS Materials
SLS is well-suited for parts requiring durability, impact resistance, and flexibility. Our typical SLS materials include:
PA12 (Nylon 12)
A versatile engineering polymer used for durable mechanical parts, housings, and brackets.
PA11 (Nylon 11)
Provides higher ductility and impact resistance for snap-fits and rugged components.
TPU
An elastomeric material ideal for flexible parts, seals, grips, and vibration dampening components.
Manufacturing Capabilities and Tolerances
Our SLS production is scaled to support industrial hardware development, machinery builds, and MRO (Maintenance, Repair, and Operations) requirements.
Note: Guaranteed tolerance requires engineering review based on part geometry, material selection, and post-processing requirements.
Functional Applications
SLS 3D printing is widely utilized by machinery OEMs, robotics integrators, and contract manufacturers to avoid tooling costs and compress lead times.
Robotics and Automation
End-of-arm tooling (EOAT), grippers, sensor brackets, and assembly aids.
Industrial Machinery
Custom guards, ducts, housings, and routing fixtures.
Product Development
Functional prototypes and engineering validation parts (EVT/DVT/PVT).
MRO and Spare Parts
Urgent low-quantity replacements for obsolete or discontinued OEM parts.
Bridge Production
Low-volume end-use parts required before injection molding tooling is completed.
Post-Processing and Finishing
Because SLS parts naturally have a slightly porous and powdery surface finish, we offer multiple secondary operations to meet your operating requirements.
Quality Documentation
Our engineering and quality team supports industrial part sourcing by providing the necessary documentation for your supply chain.
- First article inspection (FAI)
- Dimensional inspection reports
- Material documents
- Certificates of conformity (CoC)
- Shipment reports
