Researchers at Brown University have demonstrated a 3D-printing technique for fabricating “smart” biomaterials that can respond to stimuli, self-heal, and degrade on demand, paving the way for a number of next-generation medical and other applications.
In the researchers’ work, they varied stiffness, but believe other properties like strength, thermal conductivity, or porosity could also be manipulated, as well.
The system, which can either be a mobile unit or fixed to the shop floor, enables a three-step process that recovers any unused material from the printer, screens it and returns it to the machine for immediate reuse or to a container for storage.
Ultrasonic manipulation could incorporate assembly into additive manufacturing, widening the capabilities of current printers, potentially leading to the creation of a printer that could print and assemble whole devices.
Bioprinting of living human cells has gotten a boost with new research out of Sweden that’s generated cartilage tissue by printing stem cells using a 3D bioprinter.
Bone replacements for people that need them may soon become safer and more effective thanks to stronger artificial bones that can be fabricated using a new 3D-printing design.
A research team has developed a security system for additive manufacturing processes to help protect them against possible cyber attacks, as well as to ensure the overall integrity of the components produced by 3D-printing methods.
The President's efforts to promote job growth in the US manufacturing sector are being undermined by his controversial political stances and statements.
Levi Strauss & Co. has become one of the first off-the-shelf clothing companies to explore the use of 3D printing to fabricate its products, though its explorations are in the very early stages.
