SLM 3D printers are expensive, but we can use 3D printing services. In this video three different 3D printed materials are tested: stainless steel, tool steel and aluminum. From tool steel a 13mm diameter twist driss is printed too, which will be tested for drilling into aluminum and regular steel.
