| Recently, a startup American company Iro3d announced a beta version of its $ 5,000 ($ 32,000) metal 3D printer, and although there are many desktop plastic printers available for less than $ 200 on the market, the $ 5,000 retail The price is almost unheard of in the 3D printing metal field. The new system from Iro3d enables 3D printing of high-quality metals, especially steel, but the printer does not produce fully formed, solid objects. Instead, the printer uses metal sand and powder to make metal containers or crucibles. From there, In the kiln, only a toughened firing process produces a solid steel object.  In addition, Iro3d printers may be significantly simpler in some key ways than traditional plastic printers, for example, with fans, hot beds and hot ends removed and relied on the head pick-up container and auger to store them, Sand is used as support material to hold the object in place until it is cured.The two sand-based containers correspond to two different particle sizes of metal powder: one for fine powder visible on the outside surface of the print and the other for internal Filled rough powder. Currently, Ir03d sells metal and support powders for about $ 5 a pound, with a minimum thickness of 0.3mm and a system of 'pourer' (or equivalent to hot end) of 1mm with a print time of approximately 24 hours.
