We not too long ago explored how System 1 has embraced 3D printing to manufacture automobile components, check prototypes, and even information regulatory selections. Suffice to say, F1 and AM are actually tightly intertwined. Youtuber Indeterminate Design (ID) is taking that relationship to a different degree together with his absolutely practical 3D printed F1 gearbox.
Over a collection of movies, ID particulars the prolonged means of designing, printing (300+ hours), and assembling the 1:1 scale mannequin. Within the first video, he describes the technical difficulties an F1 gearbox has to beat, like managing the torque of 1,000 horsepower and 15,000 RPMs, all inside the house of 180mm. He additionally demonstrates the meeting of the principle gear clusters and the gear selector barrels. By the second video, he dives into the motors and electronics; an RC motor is used for the principle drive shaft and Nema 17 stepper motors (generally discovered on 3D printers) actuate the gear shifts. The third video focuses on his efforts in getting the shifting to work electronically and testing the max RPMs. Half 4 is devoted to the software program and management methods he created to run the gearbox as properly the housing that matches the entire electronics. And the printed F1 fashion steering wheel with paddle shifters actually ties the mission collectively. By the fifth video, he places all of it collectively and reveals the paddle shifters wirelessly shifting the gears with the motor working. It’s fairly wonderful.
Sequential gearboxes are engineering marvels, particularly the type utilized in F1 the place every little thing needs to be packed into such a tiny house. The tolerances are extremely tight and there’s little room for error. ID printed the entire components on a easy DIY 3D printer and many of the components had been printed in PLA so the success of the mission is a testomony to the engineering expertise of ID.
Within the collection he shares a pair methods to assist with tolerances of printed components, akin to making use of tremendous glue to tough areas after which sanding them easy, or wrapping a layer of packing tape round shafts to scale back friction on the gears.
ID has completed a implausible job of demonstrating that cheap 3D printers and supplies will be employed to create extremely advanced assemblies.
