Greg Zumnwalt’s Second-Technology Choose-and-Place Marblevator Is Hypnotic to Watch



Maker and 3D printing fanatic Greg Zumnwalt has put collectively a second-generation “Marblevator” marble run based mostly on a pick-and-place system — and that includes a crank-turning smiling robotic for good measure.

“‘Marblevator, Choose and Place, Model 2’ is my second ‘choose and place mechanism’ based mostly Marblevator,” Zumnwalt writes of his newest totally 3D-printed construct. “On this mannequin, I’ve changed the magnetic marble gripper utilized in my earlier choose and place mannequin with a hybrid PLA/TPU gripper which, thus far, has operated over 72 hours with a marble drop!”

Your entire marble run is designed in Autodesk Fusion 360 and printed in PLA on an Ultimaker S5s 3D printer, bar just a few needed off-the-shelf parts: TPU rubber pads, a single DC motor, two AA batteries for energy, a switched battery pack, and some wires — plus, after all, the steel marble that the crank-turning robotic retains whizzing across the monitor.

“This can be a excessive precision print and meeting mannequin utilizing at occasions very small components and in very tight areas,” Zumnwalt warns. “Previous to meeting, take a look at match and trim, file, sand, and so forth. all components as needed for clean motion of shifting surfaces and tight match for non-moving surfaces.”

“Relying in your printer, your printer settings, and the colours you selected,” Zumnwalt continues, “kind of trimming, submitting, and/or sanding could also be required. Fastidiously file all edges that contacted the construct plate to make completely sure that each one construct plate ‘ooze’ is eliminated and that each one edges are clean. I used small jewelers information and loads of endurance to carry out this step.”

A video of the Marblevator in motion is offered on Zumnwalt’s YouTube channel, whereas anybody keen to construct their very own can discover the STL information and directions on Instructables.
