My name is Constantine I'm 19 and I have a lot of experience in 3d printing (not just for my age). Our highschool had one and there was almost never a time when I wasn't printing something out. I design and print often. along with my age comes a limited amount of money and this was too good to pass up. I also think the printers system is revolutionary and will soon be copied, modified, upgraded and become very prevalent in this community.
