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.
The assessment was based on results from a number of chemical analyses of selected materials printed by the 3D printing techniques Fused Deposition Modeling (FDM), Stereolithography (SLA) and Selective Laser Sintering (SLS).
A team of researchers has developed a way to use 3-D printers to create objects capable of expanding dramatically that could someday be used in applications ranging from space missions to biomedical devices.
Using the principles behind the formation of sandcastles from wet sand, researchers have achieved 3-D printing of flexible and porous silicone rubber structures through a new technique that combines water with solid and liquid forms of silicone into a pasty ink that can be fed through a 3-D printer.
A group of researchers has discovered ways for manufacturers to turn the tables on thieves by deliberately embedding hidden flaws in CAD files to thwart intellectual property theft. In a new study, they show how certain intentionally induced defects can disappear when the part is printed under a very specific set of conditions.
