Historical note

How it all began? First, I wanted to replace a small part in a model. A trak segment, perhaps - I do not remember. I used couple of approaches, and at some point, after I got another ugly failure, that haven't had a single straight line, I thought "if only I had a 3d printer!"

Then, just out of curiocity, I looked up models and prices in the Internet.

I expected prices to start at 50 K... Well... There are printers that cost that much. However, the "entry level" prices began at 200. Dollars, not thousands. And I suddenly realized, that I want one of those toys for myself.

And yes, it looked complicated at the beginning. But few weeks later I was able to make improvements, and it was (and still is) fun.

Reprap Pyramid

Building instructions for Reprap Pyramid 3d printer

3d printer with increased size of print area.

Prusa i2 could be called a "perfect" reprap if not for its limited height of a printing area: it only has 20x20x12(up to 15 if you try really hard) cm.
Reprap Pyramid was designed by me with this limitation in mind - and it allows to print parts that are up to 30 cm tall.

Reprap Next

Building instructions for Reprap Next 3d printer

Cost efficient way to double your i2's printing area's height.

The idea is to alter the Reprap Prusa i2 at an absolute minimum cost, in order to get 21-24 cm of print height. Note, that, unlike in Reprap Pyramid, we are not going to purchase longer smooth rods: we'll reuse the 30 cm ones. We are only going to need some (not all) new plastic parts and new threaded rods ($3-4 on a local construction market). The rest: hardware, electronic components etc. - is the same.
