Constructing A RepRap: Part 1

RepRap stands for Replicating Rapid Prototyper and is also the name of the group aiming to create an open source machine that can do just that. Find out more at RepRap.org. This is our (Me, Scott, and Joel) experience creating that machine.

Step 1 Project Planning

The very first thing we decided to do was create the frame. Wood is cheap and plentiful, and since we scavenged a bunch of loft wood from the dorms last we had tons. We needed to decide on how our design would be set up. After drawing up some pictures, and discussing it for a while, we decided to split the stages into two parts. The top of the machine would be the X stage which would hold the print head, and the bottom part would hold the YZ stage.

Our linear stages would be using smooth rod scavenged from a broken copy machine to hold the stages. We made the inner dimensions of our frame the same as our rods, although now I would suggest making them an inch or so smaller so you dont need to add extra boards to mount the rods on. As for height its not too important, but we used something like 3 feet.

Shouldn't this be called a RepStrap considering the lack of printed materials?

Ooohh .. I follow this ible.

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.

I have never seen a reprap done with wood, but hats off. The simpler materials, the better. Then we will all be building things at home again.

Have a good one,
