RepRap EMaker Huxley Build


Introduction: RepRap EMaker Huxley Build

About: Currently pursuing a degree in Mechanical Engineering. contact: jamesrpatrick(at)

This is a compilation of time lapse videos from my Reprap build. Hopefully this will give you an idea of the time and, energy, and equipment involved in constructing a 3D printer.

This was first published on my blog.

Step 1: Day 1: Frame, Heatbed

The frame is constructed from threaded rod and printed ABS vertexes, in the traditional RepRap fashion.
The heatbed uses a shorted-out length of nichrome wire as the heating element. This has proven unreliable and I'm considering upgrading to a PCB heatbed.

Step 2: Day 2: Extruder, Circuit Board

The circuit board that I used is a Sanguinololu with Pololu A4983 stepper drivers(older version of A4988). This board is specifically designed for RepRaps and is contains everything on a single chip. 

Step 3: Day 3: Wiring

I have since rewired the machine and replaced numerous components. I also put the Sanguinololu PCB in a ventilated enclosure, which is mounted to the side of the Huxley. 

I highly recommend that you mount the circuit board before you ever cut a wire. It would have made this step a hell of a lot easier.

Step 4: Print!

This is my first successful print, made with PLA. It's pink because I was marking the filament with a pink sharpie to monitor the feed system.

    What I want to see is how the whole process of connecting the printer to the PC is done in terms of how it's connected and all the software needed to drive it etc. etc etc.

    everyone's instructables never seem to go into any of this at all.

    I mean is there just a printer driver, or do you need a whole laptop set up between the PC and the printer, or what's the deal?

    and the simple house number block - what did you use to design it, and how did you send the design to the printer - etc etc.

    I would also like to find an inexpensive way to make one of these. I will eventually want to increase the bed size for making automotive plastic parts that can be used, or molded.

    I am thinking about building one. What would be an good estimate on the price involved and where can you buy the parts?

    Kits can range anywhere between $300 and $1300 among different designs. Considering the shipping charges involved with sourcing parts from the many suppliers, a kit is likely the cheapest route. These usually don't come with any extra parts, so it helps if you have basic electronics equipment already. The Printrbot is probably the best bet for noobs(it's the cheapest and easiest to assemble). In any case, you'll need a good understanding of PCB assembly, heat management, and some very basic programming.

    It's important to consider that these are not consumer products, and they require lots of tuning and maintenance. 

    You can't order Printrbots yet tho, can you?

    I think they've done one run so far. There's usually a lead time for these things.
