3D Printing Steel

Notes

Iron-based alloy designed to simulate the properties of conventional steel while being used in a 3D printing process. This is not a standardized material: different 3D printing service providers use different proprietary blends. However, since the goal of the material is to simulate a specific set of properties, properties values for different formulations are similar.
