A 3D printer to turn waste plastic into composting toilets, rainwater harvesting systems #3dthursday
WOOF, the first winners of techfortrade’s 3D4D Challenge, proposed using giant 3D printers for the developing world, a project I first saw in progress at Metrix:Create Space in Seattle — where the team was at work building a giant ramshackle printer capable of making objects out of HPDE harvested from used plastic milk jugs.
The three undergraduates won to form a company that will work with partners in Oaxaca, Mexico.
Matthew Rogge, a mechanical engineering grad student, proposed to use giant 3-D printers to create composting latrines that are lightweight and use less energy to manufacture than concrete toilets.
The machine would also make rainwater catchment components that are specifically designed to fit to rain barrels, unlike current systems where joining available plumbing parts cause leaks and frequent failures.
Judges also were impressed by research the students conducted to prove their concept. In July the students printed a boat from more than 250 milk jugs and then entered it in a Seattle race. That proved they could create objects from recycled plastic and was a test run for their custom-built giant printer, also built from salvaged parts.
“With small-scale printers, the extruders can clog easily,” said Brandon Bowman, who also attended the competition. The huge printer that the students built, named “Big Red,” can not only create larger objects, but it also allows them to print with materials that are not perfectly clean.
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has thrilled us at Adafruit with its passion and dedication to making solid objects from digital models. Recently, we have noticed that our community integrating electronics projects into 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you take considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless EL Wire and LED projects that are possible when you are modeling your projects!
The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you have a cool project you’ve made that joins the traditions of 3D printing and electronics, be sure to send it in to be featured here!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
