Technology Overview

What’s New in SLS 3D Printing?

SLS is a polymer powder-bed-fusion process in which a laser selectively sinters regions of a powder layer according to the sliced CAD geometry. The platform repeats powder recoating and laser scanning until the full part is formed inside the powder cake.

For industrial buyers, current system selection increasingly focuses on build utilization, laser architecture, thermal control, material compatibility, powder refresh strategy, closed-loop powder handling and production repeatability.

Why use selective laser sintering?

Support-free complexity inside the powder bed

  • Unsintered powder supports the part during the build.
  • Multiple parts can be nested throughout the available chamber volume.
  • Functional nylons, flexible polymers and reinforced materials can be evaluated.
  • High-temperature SLS systems extend the process to advanced polymers.

Why Consider SLS?

Why Manufacturers Are Evaluating SLS 3D Printing



Manufacturing Requirement How SLS Can Address It
Complex parts without tooling
Build geometry directly from a digital model and avoid dedicated mould tooling for every iteration.
Support-intensive geometries
Surrounding powder supports the part, allowing many geometries to print without dedicated support structures.
Multiple parts in one build
3D nesting can use more of the available chamber volume for mixed or repeated components.
Functional polymer prototypes
Engineering polymer powders can support fit, function and application testing when appropriately selected.
Low-volume production
Digital production can reduce dependence on conventional tooling for smaller production quantities.
Advanced polymer requirements
High-temperature SLS platforms can extend material capability to PEEK, PEKK and PPS-class applications.

Your Questions Answered (FAQ)

Frequently asked questions for industrial buyers evaluating SLS polymer additive manufacturing.
1. What is SLS 3D printing?
Selective Laser Sintering is a powder-bed-fusion process in which a laser selectively sinters polymer powder layer by layer to manufacture a three-dimensional part.
2. Does SLS require support structures?
Dedicated support structures are generally not required because the surrounding unsintered powder supports the parts during the build.
3. Which TPM3D system is suitable for compact R&D use?
CF200 + PPS200 and S260 are logical starting points where compact professional use, research or education is central to the requirement.
4. Which systems are intended for larger parts and batch production?
S480, P550DL and S600DL provide larger build chambers. P550DL and S600DL use dual-laser configurations for production-oriented workflows.
5. Which SLS printers are designed for high-temperature materials?
S150HT and S320HT are high-temperature platforms. S320HT is positioned for advanced polymers including PEEK, PEKK and PPS.
6. What polymer materials can be considered for SLS?
Depending on machine configuration and qualified material availability, SLS workflows may include PA11, PA12, TPU, PP, reinforced nylon formulations and selected high-performance polymers.
7. What happens to unused SLS powder?
Unsintered powder is removed from the part, recovered and handled according to the material-specific refresh, sieving and reuse strategy.
8. Can SLS be used for low-volume production?
Yes. SLS is commonly evaluated for functional prototypes and low-volume polymer manufacturing because multiple parts can be nested within the build chamber.
9. What information should I share before requesting a system recommendation?
Provide the part drawing or dimensions, material, expected quantity, functional requirements, operating environment and any post-processing constraints.
