Selective Laser sintering (SLS) is a powder bed technology that uses polymer powders. A laser beam allows particles to be selectively fused within a temperature-controlled chamber in such a way that the powder is self-supporting and there is no need for support structures. This technology offers excellent finishes with almost no post-processing. The optimal balance between properties and price has made SLS technology the most demanded technology in the industry.
Prior to manufacturing, it is crucial to nest the parts to achieve high volume densities in the build. The SLS printing process begins by heating the chamber just below the melting temperature of the polymer. Then, a compacting roller spreads the fine powder particles on the surface of the platform so that a laser can selectively sinter each layer of the part. When the layer is sintered, the entire platform is lowered a few microns to repeat this process over and over again until the parts are finished.
– Send us your 3D file ready to print.
– If you do not have the file, send us the item and we will create the CAD file.
– If you need a design from zero, our designers will gladly prepare a quote for you.
– We will create the process file adapted to the technology and materials that will be used to produce your item.
– We prepare and condition the printer to guarantee optimum quality.
This step is key when meeting your requirements, and it is one that we are highly specialised in.
The removal of the printing support structures, heat treatments, and surface finishes (blasting, polishing, tooling) are some of the most common post processes.
SLS 3D printing has great potential for application in the industrial sector due to the quality of its parts. In addition, it is one of the most suitable 3D printing technologies for the production of short series, being more cost-effective than conventional technologies for batches of hundreds or even thousands of units.
This service is available in the following materials. Take a look and decide which one best suits your needs.
We design conformal cooling channels for plastic and aluminium injection inserts. With our inserts the cycle time is improved in addition to the quality of the injected item.
