TCT show at the NEC this week. 3D printing and processing of metal parts is progressing rapidly... it may actually be the future... hang my hover car won’t start again :D

Can someone 3D print me a new knee?

Very nice indeed, presumably this is in a plastic material ?

Excuse my ignorance.....but is it possible to “Print” in metal?

Could see how lead or Aluminium, with lowish melting points could work, but is it possible with steel or iron ?

Apologies if this is a stupid question :D

It is possible to 3D print i n metal to various standards & grades, but Oh! The expense. . . . .

A chap I know in the States buys up damaged alloy wheels for relative pence (cents?) from the scrapyard and uses them as donor aluminium for casting. Not a bad plan, as I'd have thought it's got to be a pretty decent grade.

This is plastic based, this particular material has short strand carbon in it (it happened to be on the machine already)

Yep, you can print in metal. Have a look at DMLS. It isn't cheap though. This is often done with titanium or stainles steel.

Plastic 3D printing is well within the 'hobbyist' realm now, however metal processes are still more specialist (and expensive)

I think we have about a dozen Ultimakers within the art college now, as well as a couple that do resin based printing (they are a nightmare, and very tricky to get anything out of) as well as much more specialist kit that print in multiple different plastics on the same piece.

The ultimakers are the 'mince and tatties' of the 3D print world, and very handy. The resin casting ones can actually print in materials that can be burnt out for mould making, but as I say, that's a bit hit or miss.

We also have a couple of machines that can print clay or other soft materials, one of which can print up to about 5' tall objects! That's a big garden gnome.

I can just about work one of the basic ones..... :lol:
