Porous Metal Spine Implant Heals Bone
News 7/19/2012 14 comments A lumbar spine implant made with Zimmer's tantalum-based Trabecular Metal Technology, a highly porous metallic substance with characteristics similar to the spongy type of bone, helps foster new bone growth to speed healing.
Video: 3D Printer Cooks Up Blood Vessels
CAD/CAM Corner 7/17/2012 9 comments A bioengineering team from the University of Pennsylvania has put the RepRap open-source 3D printer to work, making templates of blood vessel networks out of sugar as part of its work in regenerative medicine.
3D Materials Expand Design Options
Engineering Materials 7/12/2012 15 comments New rigid and rubber-like digital materials for Objet's Connex 3D multi-material printing systems offer improved toughness, more shore scale values, and resistance to heat.
A new service lets engineers and orthopedic surgeons design and 3D print highly accurate, patient-specific, orthopedic medical implants made of metal -- without owning a 3D printer. Using free, downloadable software, users can import ASCII and binary .STL files, design the implant, and send an encrypted design file to a third-party manufacturer.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
