The team uses pre-op CT scans to create 3D models of the kidneys, which are then transferred to the printer. The kidney is then printed out of two different materials so that the tumor and vasculature stand out from the rest of the organ. This allows the surgeons to initially see the tumor and vessels that will be much harder to spot during actual surgery.
This is pretty fabulous. I want to see a 3D print extrusion head on a fully mobile robotic arm, though.
Really great article about how 3D printing will compliment other manufacturing techniques, and what it’s really good for.
Never before have we had a technology where we can so freely translate our ideas into a tangible object with little regard to the machinery or skills available. Yet just as the microwave didn’t replace all other forms of cooking as initially predicted, 3-D printing will not replace other manufacturing technologies let alone industrial-scale ones for a variety of reasons. It will complement them.
The RepRap project was how I first learned about 3d printing. It has the remarkable mission, in that I’m remarking about it, of printing all of the parts to make another printer. Wow. Well, in principle, all of the circuits can be replaced with pneumatic ones. And also, you know, it might make a cool theme for a sci-fi flick. Just imagine a 3d printer printing with a background of hydraulic valves, pumps and hoses. Generate a pressure difference with steam and you’ve made a steam punk wet dream.
Anyone interested in a $300 3D printer? How cheap can one of these get?
The Printrbot Simple is an exercise in 3d printing minimalism. It includes only what is needed to get started in the world of 3D printing. At $299, we think you will agree that it is both tiny…and a really big deal.
This looks great, but screams “vaporware” to me. Mixing PLA after it’s melted to achieve different colors? Auto-leveling build plate? Built in support for PVA dual-extruder supports? It’s all technically possible, but way, way non-trivial.
But maybe! I’ll keep an eye on this one.
Insects Au Gratin looks for new ways of consuming insects and debates the nutritive and environmental aspects of insects as human food. One of the aspects that deters people from eating insects not only has to do with cultural background, but also with the aesthetics of the dishes themselves.
A project that takes insects, renders them into a sort of “flour” and then 3D prints edible objects with them. Watch the video to see the process in action.
Neat! The ability to visualize and handle 3D models of living animals internal organs and such could be a huge boon to surgeons, and make “exploratory” surgery much less common. I’ve not clue the risk/return comparison to be had between a CT scan (tons of radiation) and exploratory surgery, but I can imagine an overlap somewhere where this is preferred.
The idea to print skeletons from CT scans came from Evan Doney, an engineering student working in the lab of Matthew Leevy, who runs the biological imaging facility at the University of Notre Dame. ”At first I didn’t really know what the killer app would be, I just knew it would be really cool,” Leevy said. But he began to see new possibilities after striking up a conversation with an ear, nose, and throat specialist during an office visit for a sinus problem. “I actually got out my computer and showed him some slides, and by the end of it we were collaborating.”
Doney used several freeware programs to convert data from CT scans into a format that could be read by a 3-D printer. As a proof of principle, he and colleagues printed a rat skeleton in white plastic and printed a removable set of lungs in green or purple.
Color me highly skeptical of this endeavor, given the touchy nature of today’s 3D printers. All of the printers I’ve seen require a human operator for routine maintenance and mucking about with leveling/settings/print bed issues that would seem to me to preclude the sort of reliability that you’d need to make an actual vending machine work out. But more power to these guys if they can make it work.
Combining the hyper-local convenience of Redbox with cutting edge technology, Dreambox is a vending machine that aims to fuel the 3D-printing revolution from the bottom up.
Dreambox was created by co-founders David Pastewka, Ricard Berwick and Will Drevno, who all met in a mobile application development class and competition at the University of California, Berkeley. Frustrated by their lack of accessible, on-campus 3D printing options and the two- to four-week lead time for online 3D printing services, the trio came up with the idea for a more ubiquitous option.
