ReliefRep V.1

Here pictured is the first version of my large-format RepRap-oriented, Arduino-based, 3D printer, paintstruder, and plotter designed and built from scratch back in 2014. Printable / plottable area is almost 3 feet. 80/20 aluminum extrusion is used for the frame and most connective parts were 3D printed on my other bots. A 1/2 inch sheet of glass serves as the printbed.

Power supply, RepRap Arduino MEGA Pololu Shield (RAMPS), Y-axis motor, X-axis motor and carriage, 1 of 4 manual Z-axes knobs, and skateboard bearings. The X-carriage can fit various modular extrusion / plotting attachments.

X and Y axes belts.

Whatever works.

Rather fortunately placed pipe thanks to East Coast old building boiler heating infrastructure.

Custom X-carriage pen holder attachment pictured.

Custom 3D printable syringe-based paintstrusion system. Fits 60ML syringes and is designed to be quick-release, so that I may prepare many syringes with acrylic paint and swiftly switch them out as print-paintings are in-progress.

Example of initial paintstrusion attempts with the paint consistency mixed akin to frosting.

Experimenting here with "plotted-pourings". Instead of plunging paint via syringes, I decided to instead mix paint with a specific viscosity to drip at a flowrate that matched the feedrate of the printer.
