Hi, I think I can help you out a bit. I have two FDM printers, a 5 axis cnc and a 3 axis cnc. The FDM printers work great for work holding and making plastic parts for holding you rotary tools and a bunch of other stuff. However, for jewellery they do not have any where near the resolution for smithing.
For that you will need an SLA resin printer. Very Very messy though… Here are my choices…
** Prusa SL1 (First choice but 5 times more expensive)
Trying to figure out how to convince my wife that I need this…
- QIDI Shadow 5.5S (Second Choice)
Elegoo Mars (Third)
Phrozen Sonic Mini (Fourth) (Cheapest in price, but really good resolution.)
Creality LD-002R SLA (Fifth)
As for CNC machines a four axis is a good start but that particular one is pricey for that machine, 900 euros? Ouch!! Sometimes they do not have the resolution needed for a nice clean finish. Depending on your budget you might want to consider the PocketNC there are two versions, I have the V2-50 and I have nothing but great praise for the company and the machine. Excellent support and very personal. One support guy spent four hours with me on the phone on easter long weekend last year helping me out. There are things that you could never do on a four axis that you could on a five.
If you are thinking of the AnyCube LCD Photon, Check out the Phrozen Sonic Mini. They are very comparable and the Phrozen is getting some good reviews. Things to consider is the resolution… HD 1080p vs 4k or 8k resolution. I would go for the 4k resolution if you can, but 1080 is not bad.
Hope this info helps you a bits
