We use a 3Doodler Pro+ at work, which I think might be the most expensive one out there? I’ve got to say, it really isn’t any easier to use than the cheapest alternatives on the market… There’s just a horrendous learning curve to these things in general, although if you think of it as any other art form then I guess it’s probably comparable.

On ours, I do really appreciate the wide heat range, the ability to access the dual gear extruder during operation, and the swappable nozzles. What I don’t appreciate is the ridiculous markup, the non-standard nozzle size, and them lying about only being able to use their special proprietary filament (it’s just normal 2.85mm).

I have this pen which is $60 on Amazon. I really like it. Used it with PLA PETG and ABS with no issues. It doesn’t need as high temperatures as 3D printer as the filament comes out much slower.

I bought a cheap pen, maybe the same as the other poster, to help weld things together. Turns out I have no skills, and it looks bad. As a whole for me, 3d pens are annoying to use.
