Combining two different polymer forms can switch manufacturing of silicone parts from molding, casting and spin coating of simple forms to 3-D printing of complex geometries with better mechanical characteristics and better biological adhesion.
Much as a frame provides structural support for a house and the chassis provides strength and shape for a car, a team of engineers believe they have a way to create the structural framework for growing living tissue using an off-the-shelf 3-D printer.
A new technique by which to 3D print metals, involving a widely used stainless steel, has been show to achieve exception levels of both strength and ductility, when compared to counterparts from more conventional processes.
By using laser-generated, hologram-like 3D images flashed into photosensitive resin, researchers have discovered they can build complex 3D parts in a fraction of the time of traditional layer-by-layer printing.
Researchers introduced a new 3D printing platform that works using living matter. The research-ers developed a bacteria-containing ink that makes it possible to print mini biochemical factories with certain properties, depending on which species of bacteria the scientists put in the ink.
Engineers have developed a new desktop 3-D printer that performs up to 10 times faster than existing commercial counterparts. Whereas the most common printers may fabricate a few Lego-sized bricks in one hour, the new design can print similarly sized objects in just a few minutes.
