3D printing with metals

In selective laser melting, metal powder is fused to a solid object. Our systems are always technically up to date and achieve the highest precision of detail. Objects can be made of stainless steel, tool steel, aluminum, Inconel, cobalt chrome, and copper. Our copper is highly electrically conductive and opens up new application areas, for example in the metalworking industry. All 3D-printed metal products are media-dense and have high stability, which qualifies them for industrial use. Depending on the material, you can have wall thicknesses as low as 0.3 mm produced.

Metals for selective laser melting

In the following table you will find some of the metals that we currently offer for selective laser melting (SLM, PBF-LB/M) on protiq.com - including some selected material characteristics.

Please note: The table is not updated automatically and therefore does not necessarily represent the complete or most up-to-date material selection. As we are continuously developing the range on the PROTIQ Marketplace and adding new materials, changes may occur at any time. Please also note that the material characteristics may vary depending on the manufacturing partner.

The binding information and the entire current SLM portfolio can be found in the ordering process after you have uploaded your 3D data on our homepage. The relevant technical data sheets are also available there.

3D data check

The data check is always done automatically. This procedure guarantees a consistently high quality. After uploading your file to our server, the software checks the file for manufacturability. Small errors are repaired automatically. In the case of large errors, you will be informed before printing and asked for approval by means of a preview.

TIP: Upload your file and have it automatically repaired by the software. You will then be able to download the repaired file under the item “File Info.” In addition, the file is saved in your account.
