Seems like this cold-printing 3D pen is doing just great! Maybe the time for this tech has finally come, what do you think? BTW if you still want to get one as an early bird - u’d better hurry up

@Future_Make you’re welcome, didn’t expect you would have time to notice such a small post, that’s nice 
Love to have a add on for my kossel using the same resin.
I hope they actually produce pens. That would be a neat technology
