The 3D Printed Marble Machine by Maher Soft

pinshape

We've created an amazing 3D Printed marble machine on our latest Indie 3D Printer that takes marbles through crazy loops and turns. This incredible marble machine is completely based on rigid bodies, rigid body joints and mechanics, designed in ONSHAPE with precision and care. The assembly has approximately 34 parts printed in ABS plastic, and it can be powered by using DC motors or batteries for a fun and interactive experience. It uses a 1.5 cm diameter steel marble that starts at the bottom, rises to the top, and then returns to the bottom, making this trip about 8640 times in 24 hours.

Inspiration: Daniel Parker Printer: Indie: The Desktop 3D Printer Rafts: Doesn't Matter Supports: No Resolution: 200 micron Infill: 15-20% Notes: We've attached the instruction document along with a spare list and drawing for rod. Please refer to the documentation. NO SUPPORTS NEEDED! Some parts might not fit on a small print bed, we recommend you cut the file in 2 parts and glue later. 15-25% Infill worked best for me. 0.2 mm layer height. Try out the best settings for yourself. Steel ball bearings Go3d How I Designed This Designing was a complex process that required careful planning and tweaking, keeping in mind that all parts had to be 3D printed and support free to avoid any kind of post processing. It took us approximately 2-3 weeks to design the assembly on Onshape and a series of iterations to make a working model of the marble machine. The whole assembly consists of 34 3D printed parts, nuts, screws, and a DC motor to provide a rotary mechanism. The marble starts at the bottom, rises to the top, and then returns to the bottom, making this trip about 8640 times in 24 hours. Each step lifts the marble back up to the top of the slide in a synchronous manner. Here, the entire process starts all over again and continues so long as you keep turning the CAM shaft.
