Researchers have developed a new and more efficient approach to a challenging problem in additive manufacturing - using selective laser melting, namely, the selection of appropriate process parameters that result in parts with desired properties.
The researchers first used a 3D bioprinter to make an agarose (naturally derived sugar-based molecule) fiber template to serve as the mold for the blood vessels. They then covered the mold with a gelatin-like substance called hydrogel, forming a cast over the mold which was then reinforced via photocrosslinks.
Researchers are are unveiling PaperFold, a ground-breaking foldable smartphone. The shape-changing smartphone allows users to fold open up to three flexible electrophoretic displays to provide extra screen real estate when needed.
Soft and cuddly aren't words used to describe the plastic or metal things typically produced by today's 3D printers. But a new type of printer can turn wool and wool blend yarns into fabric objects that people might actually enjoy touching.
