Scientists 3D print cartilage to repair damaged windpipes
Believe it or not, scientists aren't yet finished discovering new ways to 3D print body parts. A team at the Feinstein Institute for Medical Research has developed a 3D printing technique that lets them produce cartilage for repairing damaged tracheas, better known to you and I as windpipes. They use an off-the-shelf 3D printer (in this case, a MakerBot Replicator 2X Experimental) to create a scaffold for the cartilage out of the same PLA filament you'd use for everyday 3D printing projects. After that, they cover the scaffold in a mix of chondrocytes (healthy cartilage cells) and collagen, 'baking' it in a custom bioreactor to make sure the cells grow properly.
The Daily Roundup for 01.16.2013
You might say the day is never really done in consumer technology news. Your workday, however, hopefully draws to a close at some point. This is the Daily Roundup on Engadget, a quick peek back at the top headlines for the past 24 hours -- all handpicked by the editors here at the site. Click on through the break, and enjoy.
MakerBot Replicator 2X eyes-on
You might remember that way back in September Makerbot took the wraps off its next generation of Replicators. Sadly, when the company invited us out for a sneak peak, the cutting edge Replicator 2X was no where to be seen. Thankfully Bre Pettis decided to swing through CES with the dual-extruding, ABS optimized version of its 3D printer in tow. Aesthetically there's not much different about the 2X -- it's the same black body and a Stepstrudder that form the heart of the device. Though, there's quite a number of tweaks to the basic feature set here. For one, instead of PLA (the corn-based plastic manufactured by MakerBot), the 2X goes for the ABS plastic favored by most other additive manufacturing devices. Since it has a tendency to crack and warp when exposed to extreme temperature fluctuations, the Brooklyn startup has brought back the heated build platform. The gaps in the frame have also been filled with clear plastic, and a pair of coverings have been added to the top and front to help keep the temperature inside stable. MakerBot also announced an update to its MakerWare package that enables dual-color printing and the addition of an API to its Thingiverse. The new developer tools will allow customers to tweak and produce completely unique products on their desktop. The Replicator 2X should, hopefully, be available soon for $2,799.

MakerBot showing off Replicator 2X 3D printer later today
The year of 3D printers? It's sure looking like it from where we're sitting. There are more companies at CES 2013 promoting consumer versions of the technology than ever before. Of course, MakerBot's not going to sit idly by and watch this all go down. The Brooklyn-based company is set to show off its Replicator 2X Experimental 3D Printer -- the dual-extruding "big brother" to its recently released second-gen printer -- at a press conference tomorrow. Hopefully pricing and available will be arriving on with it.
MakerBot Store tour (video)
After the news-filled event MakerBot held, just down the street from the Atlantic Terminal in Brooklyn, we found a fleet of cars ready to ferry us back to Manhattan. The cars weren't there to return the press to their various offices, instead they shuttled us en-masse to the brand new MakerBot Store that opened today in NOHO. The small shop sits on Mulberry St., just half a block north of Houston -- number 298 to be specific. Out front is a small discreet sign that reads "MakerBot." What will really draw people inside is the six-foot tall 3D-printed track that guides giant ball bearings through a maze of curves and spirals in the window. Step inside and the sculpture becomes interactive. You spin a large wheel (also printed) and a magnet slowly moves the orbs up the wall before depositing them at the starting point and sending them hurtling through the multi-track course (video after the break). Almost everything in the shop, down to the posts and locks on the display cases, is also printed out on the company's flagship product, the Replicator 2. In addition to buying the printers and compatible spools of plastic, you can also pick up trinkets created with them, such as the MixTape. If you want a less expensive example of the Replicator's wares, there's a gumball-style vending machine that dispenses toys when you insert a $5 token and give the knob a satisfying twist.

MakerBot unveils Replicator 2, 2X and launches retail store, we go eyes-on
The Replicator may have just been pushed off this writer's Christmas list. (Note to self: send updated letter to Santa.) But, this isn't a loss for MakerBot Industries, because it's being replaced by the Replicator 2, the newest model of 3D printer from the company. This is a big boy version of its previous devices that were aimed more at tinkerers than serious designers, and that's reflected in the $2,199 price. The build plate is significantly bigger, with the ability to spit out creations that measure 11.2 x 6.1 x 6.0 inches (410 cubic inches). That's a full 37 percent larger than the original Replicator, but the machine itself is the same exact size. The frame is no longer assembled from laser-etched wood, instead there's a powder-coated steel frame with PVC plastic sides to help shield the various moving parts and lend an air of professionalism to the affair. The extruder is designed specifically for use with MakerBot PLA, a new plastic material based on corn, that Bre Pettis claims wont expand when exposed to the heat -- which means it wont contract when it cools, leading to smoother printed objects and less cracking. The new printer has a resolution of 100 microns, by comparison, the original Replicator had a layer resolution of 270 microns. Now each layer of plastic is as thin as a sheet of copy paper, resulting in smooth printed prototypes. In a departure from previous models, the Replicator 2 is shipped fully assembled. You need only lift it out of the box and plug it in to get started. And one of our biggest complaints about the setup process, leveling the build plate, has been addressed. The new model now has a simplified three-point leveling system, what should eliminate some of the opportunity for error in the four-point system of its predecessor. The Replicator 2 even comes in an experimental dual-extrusion model for those that like life on the cutting edge, called the Replicator 2X, that retails for $2,799. To run all this there's a new software tool, called MakerWare that greatly simplifies the act of printing objects. You can even drag and drop multiple models into a virtual build platform, scale them and tweak them (either independently or simultaneously) before sending them to the Replicator 2. Perhaps, most interesting of todays announcements is the MakerBot Store -- an actual physical shop -- in NOLA NOHO. The company believes this will help expose people to 3D printing who might otherwise be confused by the concept. You can order the Replicator 2 now direct from MakerBot. But, be warned, there's a four to six week lead time on deliveries. Edgar Alvarez contributed to this report.
