Those are some fun ideas Starhalo.
Realistically though, I suspect the accuracy won't quite be good enough for pretty trinkets. Layers of 0.1-0.2mm are very small and no problem for functional parts, but they are surprisingly visible. Of course I'll certainly try such things.
The repraps are pretty good and they can be had for about $500 + a lot of work. Then there are a few kits of various qualities up to $2500 and then you enter the bottom of the commercial market and go from $3000 upwards.
I don't think there's enough interest (or application) here for me to justify the $3K machines but I'm also not going to go bottom of the range.
For about $1500-$2000 I have in mind a machine that can also handle extremely light milling. Of course we're talking extremely light duty. Less than 1mm^3/s for aluminium, so it takes at least 8 hours (probably even double that) to mill out a cavity for an 18650 cell. Not fast, but if it's CNC then I'm hoping to just walk away and let it be. Also, the accuracy on the milling is much better than the printing. So you could make trinkets that way. I'm more thinking of making PCBs since I hate making them by hand and every other option costs a fortune (either in time or money).
Yes that's right. I'm willing to spend $1500 on a printer to save $50 on professionally made PCBs.
