Some of them can do "rubber" (usually flexible TPU) too. As long as you don't want to print very big things, you can get a really good printer for under €500.
As for printing metal, that will probably never come for home printing. Even companies can barely afford these. And it's not just the price of the printer, electrically melting metal is an extremely expensive process.

You don't have to melt melt metal electrically, 6500(!) year old technology is sufficient.
What is new is the way you make the wax shape, using a 3D printer. Apparently it has become fashionable for professional jewellers to use it.
For different purposes, my 3D objects have been made from brass (via lost wax), nylon (hard, slightly flexible), and SLA resin/polymer (high resolution, smooth, inflexible).

Induction furnaces have made melting more different metals practical in a home workshop too

I was wondering what kind of spectrum analyzer it could be.
Maybe it was a bargain, I was pretty sure it's a dongle protected.

That's not really 3D printing metal. I mean the real metal printing that's used to produce things of beauty such as the Titanium brake calipers on the Bugatti Chiron.

It's a TV type unit. It has a 75R input and only 50kHz resolution. Frequency coaverage seems a but segmented too.

TV stuff is always a bit of a show stopper, despite what other features are.
For a moment I thought that maybe I can reprogram it, luckily they went pretty fast.
One other thing, I'm pretty sure I saw different prices when they were available.
Maybe there were different sets, though can't find any now.
First it was so that VAT disappeared and afterwards shipping went up 3x.
