Gebhardt 3D - up and working ...and almost finished!
Description
One day this might be a my big and mighty 3D Printer :)
I chose the same concept as ultimater and scaled it a bit up. This can be done without laser cutter, but easily with jigsaw.
first i decided to build a reprap mendel. but printing all the parts and assemble the 500screws also take a lot of time. and i don't like the design of reprap. it doesent look very aesthetic in my optinion.
so i considered to make my own design i could made within a few hours that is stable and covers the power supply boards and cables. the wooden pieces were precut by the local store. the rest was done with a jigsaw and a portable screwdriver. for material i chose beech multiplex and i broght them precut in 8 pieces:
2x 32*46 (sides)
1x 46*44 (back)
3x 30*44 (bottom mittle and top)
1x 9*44 (front-top)
1x 12*44 (front-bottom)
> about 1 sqm material, beech multiplex (about 25eur)
the parts for the building surface are made of waste from the cut-outs of the other parts. the whole box was build in 3 hours.
i dont know the effective build volume yet, but it could be up to 30l*20w*20h cm i think. btw this was another reason for designing my own case: making bigger things. tomorrow i will get the rods :)
electornics: gen7 with opto endstops / pololu stepper drivers/ usb breakout board / nema 17 steppers

awesome printer concept.
love those pictures you make from printed objects but
you cant get a good sense of size and relation in such extreme photos
Nice. I'm thinking of something similar. Do you have any design files? You mentioned full sized printable drawings. Can you upload them?
Files plox!
It looks very interesting! have you made any progress since then?
definitly! last days i assemblend the gen7 board so that i can drive the steppers now: http://reprap.org/wiki/Gen7_Bo...
currently i am working on the gantry system and extruder mount. i will make a big update with drawings and files as soon as i finished the mechanical parts. this should be within the next two weeks.
After building a Prusa Mendel, I can definitely see the advantages to building the structure in wood.
Have a look at http://makeyourbot.org/mantis9... - one of the projects from http://mtm.cba.mit.edu/
There's some good advice there re 'match drilling'.
All the best with your project.
Excellent update, looking forward to more info and print quality! Are you going to be using the same electronics makerbot uses? What about mechanical endstops?
no, not the same as makerbot. next week i'll get a gen7 kit (http://reprap.org/wiki/Generat... ). 1 board, 1 layer layout.it also includes heatbed and hotend controlling. only 4x pololus needed for the steppers. it comes with opto endstops (http://reprap.org/wiki/Gen7_En... ).
Interesting! What's the expected build volume that it'll be able to do?
I do love the idea that it can be mad by hand. Are you using all one wood thickness/type, or does it vary some? About how heavy is it right now?
Also, what's your projected build platform size? I'm assuming that the piece in the last picture is the build platform.
Do you have a fablab nearby? Stuff like this needs a CNC router (or lasercutter), not only for the precision, but also for being able to reproduce it. Handwork is a lot harder to reproduce.
looks a lot like that cubevector design actually.
Do you have any design drawings?
I disagree, I think having a design made for production by hand is great. I live in an area with a population of a couple of million people and I do not have access to a CNC router or Laser that is not a commercial venture with high prices. But with a full size printable template and some glue I can have ten exact copies of this for the price of a jigsaw blade. And from personal experience I can say that a skilled builder can build a highly precise machine with hand tools.
nice, that will be more stable and straight than the typical reprap, when it comes to the cartesian bot.

it works! but i still have to work on the extruder.. it stops sometimes :'(
That's awesome! I can't wait to see files put up and that you get a bunch of the bugs worked out.
