A 3D printed, fully legal silver coin [Source: PRINTY] A slovakian 3D print avail has produced silver coins that are actually legal affectionate .
3D printing money has long been a fantasy that people wondered would be potential. But now it ’ mho actually been done : PRINTY has 3D printed a eloquent mint that is legal attendant .
Does this mean PRINTY or others can start producing money ? not very, as there are a number of challenges. I spoke to PRINTY ’ s Radoslav Behul to find out more about this unusual project.

ExOne 160PRO 3D printer used to 3D print silver coins [Source: PRINTY] The caller, which has been around for several years, offers a variety of alloy 3D print services to clients, including use of equipment from Desktop Metal and ExOne. Currently they operate a Desktop Metal Studio System, angstrom well as two ExOne 160Pro systems, with a position to using five units in the future. Their goal is to provide low-cost 3D printing for industries unable to afford the traditional ( and expensive ) metallic 3D impression systems .
This is a commodity scheme, as there are batch of general manufacture operations that require low-volume metallic parts that don ’ triiodothyronine need the high tolerances possible in high-end metallic 3D printing .
recently PRINTY was approached by the Pressburg Mint in Bratislava for a very unusual project : 3D print a ash grey mint. The geometry of these coins was such that the mint could not produce it using traditional methods, and they contracted with PRINTY for aid under a public tender .
This is a rendering of the coin design, and as you can see it is quite building complex :
Design rendering of a complex silver coin. Note blue positions for diamonds [Source: PRINTY] I had not heard of the idea of 3D print in eloquent, but obviously its quite possible to do with the ExOne equipment. Silver, when properly powdered, can be used as a material in the ExOne binder jet equipment. obviously ExOne assisted PRINTY in developing the necessity print parameters, which were obviously highly unusual .
A 3D printed silver coin just after printing, this is a green part [Source: PRINTY] The coins are produced in a multi-stage process. They ’ re inaugural 3D printed with a binder. then a sinter work burns out the binder and fuses the eloquent particles together into a solid object. The then-silver object receives a polish, and last, in this case, diamonds were affixed to the coin, as you can see at top.

A 3D printed silver coin after sintering, but before polishing [Source: PRINTY] The coins are for two countries in the South Pacific : Tokelau, a autonomous dependent district of New Zealand, and Niue, a autonomous island in free association with New Zealand. The 3D print coins are to be legal tender in these areas, but are not intended for actual circulation. The currentness is the New Zealand Dollar .
A 3D printed, polished silver coin, but prior to diamond installation [Source: PRINTY] How unmanageable are the legal aspects of this project ? Behul explained they must provide quarterly reports to the issuing authority, the New Zealand mint. It ’ south not as if anyone can merely print coins ; they must be ordered, tracked and accepted by an actual mint .
I asked Behul about the material, and he explained :

“ 3D printing the coins with fine 999 silver wasn ’ triiodothyronine actually working with the binder fountain process, and we had to change to 925 sterling silver medal ( it ’ s a desegregate of ash grey and seven percentage copper ). This is a standard substantial for jewelry. It ’ s a much harder material, and works better when 3D print. ”

A 3D printed, fully legal silver coin, including diamonds [Source: PRINTY] I realized there could be a unique write out with this process : powder processes typically require a proportion of fresh powderize versus recycled unused powder from former print jobs. In many cases, polymer powderize systems end up trashing some used powder due to these ratios. If this was the character with silver powder, that could be a very expensive street arab token .
Behul cursorily explained that reused silver powder is very expensive, and they ’ ve managed to have “ 99 % recycle. ”
What have we learned here ? First, it ’ s possible to 3D print silver objects, including coins. second, don ’ t throw out used silver powderize ! finally, 3D printing coins is probably not something anyone should undertake unless specifically authorized. Doing so without approval will about surely generate a visit from folks in black vans.
