FAQ

Common Questions Before Starting an SLS Project

Content reviewed: 11 September 2026

What is selective laser sintering (SLS)?

Selective laser sintering (SLS) is a powder-bed fusion process that uses a laser to fuse polymer powder layer by layer. The surrounding powder supports the build, so many complex geometries can be produced without separate support structures, subject to wall thickness, escape holes, orientation, material, and finishing requirements.

When should engineers choose SLS 3D printing?

SLS is a practical option for functional prototypes, complex nylon geometries, and low-volume parts when avoiding dedicated support structures and injection tooling is valuable. It may not be the best choice when the project requires a mold-grade cosmetic surface, a material unavailable for SLS, or economics that favor established high-volume tooling.

How should PA12, PA11, and glass-filled nylon be selected?

Select the material from the application requirements, then compare the current grade data and relevant printed-part tests. Review stiffness, ductility, impact behavior, moisture exposure, temperature, surface finish, orientation, and inspection needs. Material-family names alone are not enough to confirm performance for a specific design.

What quantities can TPM3D review?

TPM3D reviews both prototype and batch RFQs. The practical quantity for one project depends on part size, build nesting, material, inspection, finishing, schedule, and target cost. Send the expected quantity or quantity breaks so the engineering team can confirm capacity and project-specific pricing.

How long does an SLS project take?

Lead time is confirmed after reviewing file readiness, quantity, material availability, nesting, machine schedule, cooling, post-processing, inspection, and destination. Include your required delivery date in the RFQ; TPM3D will confirm a project-specific production and shipping schedule rather than applying one timing claim to every order.

What information is needed for an SLS quote?

Send a CAD file such as STEP, STL, or OBJ together with quantity, material preference, surface finish, critical dimensions or tolerances, inspection requirements, application conditions, shipping destination, and target delivery date. If a material or tolerance is uncertain, identify the functional requirement for engineering review.
