I would like to get together with people in the Los Angeles area to start a RepRap group. I have some interesting ideas on how we can utilize these machines to bring awareness to the project and work on solving some serious social issues.
fascinated by this whole idea.
not building one yet, (too lazy), but keen to get involved with the discussion, and hoping to add a little bit of my mass to the project.
four things came to mind.
the supports, and general hardware for the device could be made internally.
could you print hollow tubes? maybe fill them with mud or clay for mass and ridgidity.
do you think there would be any use in looking at "expanding foam filler", (the stuff that comes out of a can, hardens on contact with moisture), as a rather coarse, but quick curing, printing material. this could print large parts very quickly.
any value in printing "upside down". bee's and wasps do it when printing their hives.
could it print a cheap photo voltaic cell?
would love to have this kind of conversation in company, possibly in the pub.
i live on the westside of LA. My only experience would be woodwork, (but all my tools are in england), and motorcycle maintanance, valve adjustment, servicing etc.
i did look into building a telescope once, and i can tell you there is already a lot of experience out there with amateur builders and highly precise computer control systems for telescopes with stepper motors.
