This page will document OSE's attempts to build the metal frame for the D3D without welding or cnc. Instead, we try to use metal strips glued together with epoxy.
Benefits
If someone building a D3D printer can make the frame with epoxy, then they won't need a cnc machine or welder. That makes the machine much more accessible to a wider audience, further spreading the distributive economy enabled by this machine.

Issues
The quick-set epoxy that we used (60-second handling time) was supposed to set in 5 minutes and be fully hardened within 1 hour.
After 1 hour, however, Marcin pointed out that the epoxy was still relatively soft. It could be the brand that we used. We simply went to the local hardware store and bought the only quick-set epoxy that came with two tips. It was a brand called "Devcon home." Perhaps we would have had a better experience with jbweld. And User:Abe pointed out that a marine epoxy may work better too.
