Now we can 3D print ceramics
Despite being able to build just about anything with 3D printing, until now items have been limited to polymer plastics, a handful of metals and glass. However, researchers at HRL Laboratories have announced a significant advancement in additive manufacturing: the ability to print ceramics. The trick, the HRL team figured out, was to not heat ceramic powder. Doing so generates too many microscopic flaws that can lead to cracks and fractures. Instead, the team developed a material they're calling "preceramic polymers" that convert to ceramic when heated. Essentially, the HRL team prints out the 3D design using these preceramic polymers and then fires the resulting item (like in a kiln) to harden the material into ceramic.
Shapeways Glazed Ceramics make 3D printed objects you can eat off of
We've seen them spit out fancy glass vases and tiny white strandbeests, and now the 3D thingy makers are pumping out cutesy salt and pepper shakers. Those hyper-glossy white rabbits pictured above are some of the first spawns of Glazed Ceramics, the newly minted food-safe material available from Shapeways. Glazed Ceramics are fired in an oven or kiln like traditional ceramics and are then coated with a lead-free non-toxic gloss -- the result is food-safe, recyclable, and heat resistant up to 1000 degrees Celsius. The new material is now available to Shapeways designers and will be until August 12th, at which point the company will decide whether its worth keeping around. For now you can sate your appetite for 3D printed shiny white dishes by clicking the source link below.
Nendo's ceramic circuit board speaker gives the rest of the audio world body image issues
We've seen slick hand-crafted ceramic speakers in the past, but this one millimeter-thick collaboration between potter Mitsuke Masagasu and design firm Nendo is in a different league. An entirely different league. The set is result of the so-called Revalue Nippon Project, created by Japanese footballer Nakata Hidetoshi to revive traditional Japanese art forms. Nakata selected five curators -- in this case the director of the 21st Century Museum of Contemporary Art in Kanazaw -- who were then tasked with pairing a ceramicist and designer to collaborate on a one of a kind form. Not satisfied with simply being 31 times thinner than the emaciated Mythos XTR series as a sole basis for artistic impact, the speaker's ravishing circuit design is also made without a human touch. Instead, a computer-controlled process cuts thin slices from a ceramic substrate slab, fixes them with mercury vapor, and then mounts them via a robotic arm. Amazingly, sound quality is still also touted as being top notch. There are no plans however for these speakers to ever be mass produced, so if you were hoping to snag one as the ultimate accessory for your über-modern flat... well, let yourself down easy, alright champ? %Gallery-108170%
Pixel casting machine creates pixelated vases for our pixelated flowers
We're going to give it to you straight: if we had the room for this beast, we'd totally kill for one. It's a pixel casting machine, meaning that it creates beautiful, pixelated ceramics -- like the ones you made in grade school, only way, way more awesome. Hit up the source link for creator Julian Bond's website where you can see many more photos.
World of WarCrafts: Cross-faction goblet
World of WarCrafts spotlights art and creativity by WoW players, including fan art, cooking, comics, cosplay, music and fan fiction. Show us how you express yourself; contact our tips line (attention: World of WarCrafts) with your not-for-profit, WoW-inspired creations. What happens when you combine an art class degree requirement with a WoW player who's been locked out of the game due to the school's unresolved router issues with Battle.net? For Hurbz of US Sargeras-A, you get "WoW on the brain," plus this classy faction goblet. "This was my first real experience with pottery," he admits, "and though I had done some projects earlier for the class, this was my first time using the potters wheel." We'd say this guy deserves an A -- and a clear path through his school network's Battle.net issues. Let the guy get his game on so he's not throwing WoW into every project he gets his hands on, hmm? More details from Hurbz on how his creation came together, after the break.
NC State gurus develop new material to boost data storage, conserve energy
We've all assumed that anything's possible when dabbling in the elusive realm of spintronics, and it seems as if a team at NC State University is out to prove just that. While using their newfound free time on Saturdays (you know, given that the football team has quit mid-season), Dr. Jagdish Narayan and company have utilized the process of selective doping in order to construct a new type of metallic ceramic that could be used to create a "fingernail-size computer chip to store the equivalent of 20 high-definition DVDs or 250 million pages of text." The material could also be used (in theory, anyway) to create a new generation of ceramic engines that could withstand twice the heat of normal engines and hit MPG ratings of 80. Granted, this all sounds like wishful thinking at the moment, but we wouldn't put it past the whiz kids in Raleigh to bring this stuff to market. Too bad the athletic director doesn't posses the same type of initiative. [Thanks, Joel]
Piggy speakers are so cute they make us wish we were still vegetarians
We've seen enough little portable speakers in our day, and we're pretty hard to impress at this point. Now, we're not saying that we're "impressed" with the little ceramic pig speaker that you see in the image above, but... there's something somewhat special about it. While we don't have any specs on this one, we can say with a reasonable amount of certainty that this little speaker's not going to impress even the beginner audiophile, but still, we think it's cute enough to warrant a place on our desk, right between our Fender Mini-Deluxe amp and the tiny reproduction Parrothead visor we made for our Chihuahua. These little porkers (which can be plugged into your favorite PMP for maximum blasting of "Margaritaville" on-the-go) seem to be available in Japan only for the time being, and they run ¥4,725 (about $50). They also come in several different colors -- a photo of the other options is after the break. [Via Technabob]
Far Infrared HandStrap: Mysteries of the Unknown
This exotic wrist strap claims to make use of bio-ceramics, a composite of lead-free minerals, to douse your arm with far infrared rays and help with blood circulation. Though "far infrared rays" might sound sinister if you're not familiar with them and their uses, they are supposedly quite healthy.You can't see far infrared rays in the sun's light, but you can feel their warmth absorbed into your skin. In addition to their blood circulation benefits, these miracle beams are also said to naturally reduce inflammation, decrease pain, and revitalize skin cells. All that for only 780 yen (approximately $6.33)!
