Constructing A RepRap: Part 1

Step 2 Build the frame

First we cut four boards to length for the vertical posts, then we cut 8 boards for the sides. We essentially just created a box frame. Assemble the side boards into two rectangles, making sure that you keep them square. Next, attach the vertical boards on the inside of each rectangle. Keep making sure that your boards are square... this will really help things out later. Finally attach the second rectangle to the assembly, and you will be nearly done. Once we had it assembled, it was a bit wobbly, so we added diagonal cross bracers. After that it was rock solid and very sturdy.

Next, you will want to mount some boards where you want the YZ stage to go. Mount this about halfway up the frame, as they will protrude below the mount when the Z stage is all the way down. You can always adjust the height once you get the whole thing assembled.

If you want, you can optionally pimp out your lovely box with some wheels to help you move it around. These simply get screwed to the bottom of the posts and definitely give your RepRap some street cred.

Now you have the frame assembled, and its time to create the linear stages!

what is a reprap

[chiok]

RepRap is a real clever idea that they're pioneering at the University of Bath. The idea comes from rapid prototypers (those 3D printer things that make objects by adding layers together). The concept is about making an entire rapid prototyper with the machine, essentially cloning itself. This would allow you to essentially duplicate one yourself for only the cost of power and materials, and then use it to make whatever else you want (as long as it's plastic). If there was one in each home, then everyone could make alot of things they'd normally buy which could result in all sorts of economical breakdown, but it's still a neat idea. I saw some of the RepRap stuff but didn't get a chance to work on it when I was in the department. I've never heard of a third-party trying it out though, so I'd be very interested to hear how it works out. I'd love a rapid prototyper.
