This project started with my son when i started to learn him how recycling and fixing are important for his future and the earth. 3d printer is for me a formidable machine that can contribute for a responsible consummation. It can contribute to the development of imagination and is a good approach to mechanical, programming, electronics, engineering ... My specifications : A compact design. Easy to move and use. The print area is 10 cm x 10 cm x 10 cm. Filament roll stored in the machine (250g spool). Compatible with regular nema17 steppers and GT2 belt. Modular head. The must important : use a maximum of scavenged components and 3d printed parts with PLA (biodegradable). However, i don't want a poor machine, it must have good prints. So i had to buy some parts like bearings because i didn't find better solution. All parts i bought are cheap but do their job. I chose the coreXY arrangement because it corresponds to my specifications and it need only one motor for the Z axis. I designed all the parts except a remix of the bowden extruder (by Schlotzz https://www.thingiverse.com/thing:275593) and the clamp for linear bearings (by Dagoma https://www.thingiverse.com/thing:1754185). As you can see in the picture the first user is my son. In the first photo you can see everything the machine printed (tests and fails comprise). The machine can print with 0.15mm resolution and the longer print i do was 3 hours (motors are very small so they heat faster than the classic nema 17). All the steps are in my Instructable https://www.instructables.com/id/Green-Core-XY-a-3D-Printer-With-Recycled-Component/. Best regards.
