Claim 19:
20. A method of forming a part via additive manufacturing, the method comprising the steps of:
filtering hollow salt micro-spheres via two sieves so that the filtered salt micro-spheres have a diameter within a range based on the two sieves;
mixing the filtered salt micro-spheres with an additive manufacturing material to form an additive manufacturing material mixture;
depositing the additive manufacturing material mixture onto a build platform;
curing the additive manufacturing material mixture above at least 270 degrees Fahrenheit via a curing device so as to create a structure having pores formed by the filtered salt micro-spheres; and
flushing the filtered salt micro-spheres from the pores via warm water.
