HP announced a partnership with Legor to enable 3D printing of precious metals, including gold and silver.
A Slovakian 3D print service has produced silver coins that are actually legal tender.
New research seems to have developed an incredibly effective method of 3D printing speciality filters to extract specific metals from waste material.
Could any 3D print service print in precious metals like gold, silver or platinum? Not unless special steps are taken.
