The EchoRap is a simple and robust RepRap designed by Robotic Sequencing in Montrealâ€™s first and only Fab Lab, Ã‰choFab. Itâ€™s a low cost and simplified version of the original RepRap using tubes instead of threaded rods for a different geometry. The design is licensed under Creative Commons Non-Commercial, so if you have acces to a 3D printer, you can print one for yourself or to give to a friend. Files to print parts are available on Thingiverse.
The design allows builders to build it as a RepRap or a RepStrap.
All parts can be printed or cut.
Assembly of the structure is very easy: tubes and simple coupling.
The X Y Z axes can be enlarged using longer tubes and rods.
Current table size allows the use of standard Mendel or Prusa heated beds.
Gen7 Electronics, PrintrBoard rev D has been tested and works well. Other RepRap electronics can also be used. All the sofware is Open-Source.
Overall Dimensions: 510mm x 585mm x 540mm (20.1in x 23.1in x 21.26in)
Weight: 8.18kg (18lbs)
Usable Print Area: 220mm x 220mm x 200mm (7.9in x 7.9in x 7.87in)
Note: REV 1 add stiffness to the X axis by replacing the 2 P4Z Top Mount with 2 extra P3Z with 608zz bearing to add stiffness to the X carriage.
