Quick photo tour of my RepRap 3D Printer

I thought I’d show some pictures of my current set-up.

Here it is. It's never totally finished, so its appearance has changed and will change in the future.

This is a part mid-print. It is made out of silver ABS and with a setting of 40% infill density. It is printing a tall "skirt" around the part to help prevent part warping. The glass plate is coated in dollar-store hairspray for adhesion, and the bed is heated to 110 C.

This is one of the ends of the X-axis. NEMA 1.7 stepper drive, with a T2.5 belt and pulley. The other end uses a 608 bearing as an idler.

Y-axis drive motor. The other end is another idler bearing.

This shot gives you an idea of how the frame is constructed.

The underside of the Y-axis carriage. LM8uu linear bearings on 8mm drill rod are held by printed parts bolted to a laser-cut MDF plate. Also seen is the bed levelling hardware and heated bed wiring (which needs to be made prettier).

The Z-axis uses plain 8mm threaded rods as leadscrews. This may not be the best solution, but it's very accessible and cheap. The couplers are printed, and the motor shaft is gripped by a bit of clear rubber tubing.

This is the filament spool holder that I am using. It's just some spare threaded rods hooked up with zip ties.

Nothing glamorous, just one of the Z-axis motor mounts.

Electronics. An arduino with a custom sheild, the combination is known as "RAMPS V1.4".

Finally, the power supply. It is a converted ATX PSU from a computer. I originally made it for doing labs when I was in college robotics.. it can provide the amperage required for the hot end and heated bed.
