Researchers investigated a new combination of 3-D printed microfiber scaffolding and hydrogels. The composites they tested showed elasticity and stiffness comparable to knee-joint tissue, as well as the ability to support the growth and cross-linking of human cartilage cells.
Manufacturing researchers at the National Institute of Standards and Technology (NIST) have scoped out the missing sections in current guidelines for powder bed fusion, the chief method for printing metal parts.
Researchers have whittled the cost of printing to ten cents per kilogram - down from $30 per kilogram. They made this leap by recycling plastic that had already been printed, using a recyclebot and plastic resin codes developed by the team.
A UC Berkeley research team unveiled the first and largest powder-based 3-D-printed cement structure built to date. The debut of this groundbreaking project is a demonstration of the architectural potential of 3-D printing.
The 3-D printing scene, a growing favorite of do-it-yourselfers, has spread to the study of plasma physics. With a series of experiments, researchers at the Princeton Plasma Physics Laboratory have found that 3-D printers can be an important tool in laboratory environments.
Scientists at VTT in Finland have developed a prototype of a tree that harvests solar energy from its surroundings - whether indoors or outdoors - stores it and turns it into electricity to power small devices such as mobile phones, humidifiers, thermometers and LED light bulbs. The technology can also be used to harvest kinetic energy from the environment.
