Researchers introduce a polymer made entirely from biomass that can easily and inexpensively be used in 3D printing. Objects produced in this way are of high quality, easily recyclable, and highly solvent-resistant.
Researches are hard at work around the world trying to develop viable, transplantable replacement organs using 3-dimensional printing as a way to solve the shortage of donor organs, whether it's lungs, heart, kidneys or any other organ that can fail.
The temporary structures, which can be degraded away with a biocompatible chemical trigger, could be useful in fabricating microfluidic devices, creating biomaterials that respond dynamically to stimuli and in patterning artificial tissue.
Scientists are investigating the entire 3-D printing process, including the material properties of the metal powders and how the laser melts and shapes those powders into the desired components, to discover both how defects form and methods to avoid them.
Researchers present a new approach for selective laser melting of copper materials. In the future, it should offer users the first cost-effective method for 3D printing components made of pure and highly conductive copper.
A diverse scientific collaboration has developed vascularized 3-D bioprinted liver tissue constructs, providing more precise drug toxicity testing and possibly providing tailored testing samples using a patient's own cells.
