SLS 3D printer
Detailed components, complex geometries and maximum material diversity - without support structures.
SLS stands for Selective Laser Sintering. In contrast to the SLA process, no liquid mass is hardened here, but polymer powder is fused in very fine layers. A major advantage of this technology is that no support structures are required.
SLS 3D printers are suitable for companies that want to manufacture customer-specific products or require functioning prototypes. With the excellent mechanical properties of the materials, ready-to-use finished parts can also be produced - whether for industry, product development or model making.

No support structures required
SLS 3D printers build complex shapes freely in the build space - without any additional support materials. Instead, the component is stabilized by the surrounding powder during the entire printing process. This reduces post-processing, saves time and lowers material costs.
High resolution and precision
With layer thicknesses from 75 µm and an impressive level of detail, even the finest structures can be printed - ideal for prototypes, small series and complex geometries.
Wide choice of materials and sustainability
SLS 3D printers support a wide range of materials, including PA12, PA11, TPU and fiber-reinforced polyamide. Unmelted powder can be reused directly for the next printing process. This results in less material waste and keeps production costs low.
Challenges when using SLS 3D printers
The entry into SLS technology offers many advantages, but also brings with it specific challenges. From powder handling and the right infrastructure to converting from FDM or SLA - here is an overview of the most important points.
Cost-intensive purchase
The investment in an SLS 3D printer is usually higher than for FDM or SLA systems. In the long term, however, the costs are amortized through material savings and the robust design.
Powder handling and storage
Handling fine powder requires a clean environment and special storage. Residual powder can be recycled and reused.
Space requirements and infrastructure
An SLS 3D printer offers professional printing results, but also requires a well-equipped production environment. This includes secure storage areas and efficient material processing.
Conversion from FDM or SLA to SLS
Many entry-level printers are based on FDM or SLA technology. Switching to SLS requires a rethink in terms of material handling - but offers significantly more options and greater precision
Video: Understanding SLS 3D printing - using the Lisa X workflow as an example
How does selective laser sintering actually work in practice? In this video, you will see step by step what a complete SLS printing process looks like - from file upload and printing to powder recovery and post-processing.
The process is demonstrated using the Lisa X system, including cleaning and material preparation. You will gain a realistic insight into:
- How an SLS printer works
- Handling powder and components
- The most important steps for a clean, efficient workflow
- Options for material recovery and process reliability
Ideal for anyone who wants to get to know and better understand the SLS process.
Post-processing & accessories - clean results, efficiently implemented
After printing, the component is embedded in the powder bed. To be able to use it, the excess powder must be removed - coarse and fine.
The complete SLS workflow also includes sieving the powder, cleaning the machine and recovering and reusing the material. These steps not only ensure print quality, but also reduce material costs.
In many cases, this is followed by a sandblasting process that removes loose particles and ensures clean, dimensionally stable surfaces.
SLS accessories - For a smooth workflow after printing
From powder handling to surface finishing: for professional SLS printing, it's not enough to just have a good device - the accessories also need to be right.
With the right setup, you can ensure clean processes, less material loss and consistently high component quality. The right components for printing, cleaning and powder management make all the difference.
Available as an accessory:
- Powder handling station - powder recovery and preparation
- Powder sieve - For optimum recycling
- Vacuum cleaner (ATEX-certified) - safety when vacuuming and cleaning
- Tool set - For safe and clean handling of the printed parts
- Sandblaster - For finishing and improving the surface quality
- Machine frame - For more order and flexibility in the working environment
- Print preparation software - For seamless operation and job management
Ideal for anyone who wants to map their SLS printing process professionally and economically.
