Yeah, 3D printing has really come a long way. I like that there are more useful things now instead of just novelty items. I'm actually looking into getting my own printer at some point. The LED one is my favorite as well and yes the screwdriver works quite decent in the tool pen.
SLS printing seems to be something that is becoming kinda affordable at home.
Read somewhere a few k$??
No idea about operating costs.
I was a bit detached from the 3D market segment for many years, but got a spark of interest again last weekend when I went to see the works by fashion designer Iris van Herpen. She uses quite a bit of 3D printing techniques in her creations. Actually, that was the reason for me to go and see her collection 🙂
Yeah, here in the US you can get a pretty decent model for around $1500. Depends on how fancy you want to get.
