What do TPM3D SLS prototyping services include?
TPM3D SLS prototyping services cover CAD and DFM review, material selection for PA12, PA11, or project-specific alternatives, SLS printing, cleaning and post-processing, agreed inspection, packing, and delivery. The exact scope, quantity, finish, tolerance checks, and schedule are confirmed from the RFQ before production.
What quantities can be reviewed for SLS production?
TPM3D handles quantities from a single piece up to 1,000 pieces. Practical capacity and pricing within that range depend on part size, nesting, material, inspection, finishing, and schedule. Provide the expected quantity or quantity breaks for a project-specific assessment.
How is SLS production lead time confirmed?
Typical lead time is 4–5 days. The exact schedule is confirmed after file review and depends on file readiness, quantity, material availability, nesting, machine loading, cooling, post-processing, inspection, and destination. Include the required delivery date in the RFQ so production and shipping timing can be checked for that project.
Which file formats are accepted?
TPM3D accepts STEP, STL, OBJ, and common CAD exports. STEP files and dimensioned drawings are useful when assemblies, critical dimensions, tolerances, or inspection criteria matter. Mesh files should be watertight and use clearly stated units.
Can SLS be used for functional end-use parts?
SLS can be suitable for functional nylon parts when the selected grade, geometry, orientation, finish, loading, environment, and validation plan match the application. Suitability is not determined by the process name alone; safety-critical or regulated uses require project-specific engineering evidence and approval.
When is SLS not the best manufacturing process?
SLS may not be the best fit when the required material is unavailable for powder-bed fusion, a mold-grade surface is mandatory without added finishing, critical tolerances exceed the validated process capability, or established high-volume tooling provides better economics. The decision should be made from the actual CAD and requirements.
What post-processing options are available?
Available options can include bead blasting, dyeing, smoothing, polishing, painting, threading, inserts, and assembly preparation. Compatibility depends on the polymer grade, geometry, color, surface target, quantity, and end-use environment. Confirm the required finish and acceptance criteria before quoting.
What is the maximum build size for SLS parts?
Our in-house build envelope is up to 600 × 600 × 800 mm. If your part exceeds a single build, include the dimensions in your RFQ so our engineers can confirm the best approach.
What does an SLS 3D printing service include, and how is pricing set?
Pricing is set per project; there is no fixed price list. Quotes are based on DFM review, material, quantity, finishing, and inspection requirements, with cost drivers itemized in the quote. The service includes CAD and DFM review, material selection, printing, cleaning and post-processing, agreed inspection, packing, and global delivery.
When does SLS prototyping beat injection moulding for low volumes?
When you need single pieces or small batches, complex geometries, or parts where no mould tooling cost can be spread across volume. See also the companion answer on when SLS is not the best process.
