Abstract
A method for producing a metal shaped article having a porous structure includes a mold formation step of forming a mold having a plurality of columnar structures extending from a substrate by performing a resin material supply step of supplying a liquid containing a resin material to a plurality of places of the substrate at intervals in two directions crossing each other, and a curing step of curing the liquid, a sintering target material supply step of supplying a sintering target material to the mold, a removal step of removing the substrate, a degreasing step of degreasing the columnar structures, and a sintering step of sintering the sintering target material.
Claims8
A method for producing a metal shaped article having a porous structure, comprising:
- placing a substance on a stage;
- forming a mold having a plurality of columnar structures extending from the substrate by:
- ejecting a liquid from a head as a liquid droplet containing a resin material to a plurality of places of the substrate at intervals in two directions crossing each other, and
- curing the liquid;
- supplying a target material to the mold, the target material being one of:
- magnesium (Mg), iron (Fe), cobakt (Co), chromium (Cr), aluminium (Al), titanium (Ti), copper (Cu), nickel (Ni);
- or
- a mixture containing one or more of the magnesium (Mg), iron (Fe), cobalt (Co), chromium (Cr), aluminium (Al), titanium (Ti), copper (Cu), and nickel (Ni);
- removing the substrate from the stage;
- degreasing the columnar structures with an external heating device;
- and
- sintering the target material with the external heating device to produce the metal shape article.
