EchoRap Rev1

thingiverse

The EchoRap is a low-cost, simplified version of the original RepRap 3D printer designed by Robotic Sequencing in Montreal's Fab Lab, ÉchoFab. It uses tubes instead of threaded rods for a unique geometry and is available under a Creative Commons Non-Commercial license, allowing you to print one yourself using a 3D printer and files provided on Thingiverse. The EchoRap can be built as either a RepRap or a RepStrap, with all parts able to be printed or cut, and assembly is easy thanks to its tube and simple coupling design. You can also expand the X, Y, and Z axes using longer tubes and rods, while standard Mendel or Prusa heated beds are compatible with the current table size. Gen7 Electronics and PrintrBoard rev D have been tested and work well, and all software is open-source. The EchoRap has overall dimensions of 510mm x 585mm x 540mm and weighs 8.18kg, with a usable print area of 220mm x 220mm x 200mm. Revision 1 of the design added stiffness to the X axis by replacing two P4Z Top Mounts with two extra P3Z units with 608ZZ bearings. To build your EchoRap, you'll need structure materials like Y and Z-axis tubes, top tube handle bars, joints, and specific parts such as NEMA 17 mounts, bearing holders, and extruder mounts. You'll also require moving parts like 12mm rods, LM12UU bearings, and pulleys, along with hardware for assembly. Electronics include NEMA 17 stepper motors, PrintrBoard rev D, a Wade extruder, J-Head hotend, PCB heated bed, and an ATX power supply. Don't forget the cables! Documentation and software are available on GitHub and the EchoRap Wiki (in French). Get ready to print and create with your very own EchoRap RepRap 3D printer.
