A University of Washington engineering professor has come up with a new goop for his 3D printer that costs 1/30 - 1/50 of the authorized goop, using a mix of clay, sugar and nutritional supplements, then open sourced their formula. Basically, these guys are the inkjet cartridge refillers of the 3D era:
About five years ago, Mark Ganter, a UW mechanical engineering professor and longtime practitioner of 3-D printing, became frustrated with the high cost of commercial materials and began experimenting with his own formulas. He and his students gradually developed a home-brew approach, replacing a proprietary mix with artists' ceramic powder blended with sugar and maltodextrin, a nutritional supplement. The results are printed in a recent issue of Ceramics Monthly. Co-authors are Duane Storti, UW associate professor of mechanical engineering, and Ben Utela, a former UW doctoral student.
"Normally these supplies cost $30 to $50 a pound. Our materials cost less than a dollar a pound," said Ganter. He said he wants to distribute the free recipes in order to democratize 3-D printing and expand the range of printable objects.
Glitzy three-dimensional printers have become common in the industrial world, churning out fast 3-D prototypes of everything from airplane parts to running shoes. But the machines also are becoming popular among artists, hobbyists and educational institutions.
The Good Junk (@thegoodjunk) is a blog which posts a beautiful gadget a day. Not all of them are 40-year-old Braun or B&O appliances, either! (A lot of them are.) Pictured above is the Casio XW-PD1 performance synthesizer, which was made in 19A5. Below is a MINITEL terminal.
Super Retro-Boy is a compact, minimal reimplementation of Nintendo’s classic Game Boy with the look as well as the tech. It plays real cartidges, including those from the full-color Game Boy Advance—presumably this is why there are four buttons. It gets 10 hours on a charge, and will come with a 10-in-1 game from Retro-Bit […]
A T-Mobile customer in Florida drove her SUV into the store, smashing through the front window and coming to a stop deep in the showroom. Then she emerged from her disabled vehicle, hefted a broken window frame, and smashed a display. “What is wrong with her?” calls out an unseen observer. According to witnesses who […]
