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.
A flashlight review that begins with the promise “I’m about to hike through a remote canyon to an abandoned mine, and I gotta tell you there’s a storm raging outside” should end on an interesting note, and this one does. [via] Disturbing, strange sounds. That’s exactly what I caught on video while filming and documenting […]
Reflectacles, the hyper-reflective Ray Ban-style $75 glasses frames that Scott Urban is Kickstarting have a new feature: now you can get ones doped with materials that reflect the infrared light that CCTVs kick out to let them capture images in low light, which blind cameras’ sensors. Cool!
Typewriter historian Martin Howard (previously) writes, “I was able to pick up a rare and exquisite Waverley typewriter (1896) this summer in Scotland and have just the other day posted it to my website all cleaned and ready to show.”
Loot Crate is a totally different kind of subscription service that mails subscribers monthly boxes filled with curated geek, pop culture, and gamer paraphernalia. Its cult following awaits a box every month filled with everything from bobble heads to T-shirts to special edition collectibles. But nothing gets Loot Crate fans as excited as the limited […]
The ARMOR-X Mini Flexible Phone Tripod is a smartphone tripod that is designed with flexible legs to rest on virtually any type of surface. Other tripods have proved useless unless I conveniently have a flat surface in front of me, which is why this particular tripod was appealing enough to try out. The ARMOR-X is compact and easy […]
You don’t need to get an advanced degree and take out massive loans to become a coder. This bundle of 10 courses was designed to teach anyone to code at home for less than it costs to go out for dinner. I was particularly impressed with this new 2017 bundle because it includes courses on […]
