Building an oversized Huxley

I am writing this blog to document my progress building the experimental Huxley RepRap. After looking at other people’s attempts i decided to make a oversized Huxley as it gave the best of both worlds – a decent sized build platform and a reduced cost compared to Mendel.

I am a postgrad at Nottingham University and am lucky enough to get limited access to a Stratysis Dimention 3D printer, which served as a source for the original parts i needed.

Below is a screen shot of my initial print bed. It contains the parts needed to make the frame, y-axis, z-axis, and x-axis. I chose not to print an extruder carriage as this is an area which is constantly evolving, and i chose to wait until the last minute to print it!

I chose to use MarcusWolschon’s hollow mini-mendel files as a base as i needed to reduce the build volume of the parts. Once the parts were printed i filled the shelled parts with casting resin which gave the parts excellent mechanical properties.

I replaced a few of the standard parts with some which simplified things:
Whosawhatsis designed some nice parts: y-bar clamps , Z-leadscrew clamp & Idler pulleys
Nophead's improved stepper motor pulleys

Below is a filled part (y-axis idler bracket)
