  • Patent number: 11192182
    Abstract: A substrate for 3D printing using a cold spray technique. The substrate of the present invention has a porous surface with the size of pores smaller than approximately 24.4 times the mean particle size of feedstock powders for cold spray processing and larger than or equal to approximately 6.84 times the mean particle size.
