Hi,
since I occasionally do 3d printing workshops I thought about getting a 3d printing pen, so I looked around an ali and banggood and they start at 30$ which is fine, but I also remembered some negative reviews about those pens from 1-2 years ago. I dont know if they have gotten so much better that even the cheap ones are usuable.
So has anyone made some good experiences with a cheap 3d printing pen?
Cheers
