Light powers faster 3D printing

Light powers faster 3D printing

Science
Jan. 11 (UPI) -- Scientists have developed a new technique for faster, more efficient 3D printing. Instead of building objects layer by layer, the new method uses light to solidify 3D shapes from a vat of liquid. Traditional 3D printing methods don't make sense for small-batch manufacturing jobs with a quick turnaround time. The new technique, which uses a pair of light beams to control which bits of liquid resin become solidified and which remain in fluid form, could allow manufacturers to turn around small batch projects in a couple of weeks. Whereas traditional 3D printers build three dimensional objects using additive techniques, combining 1D lines or 2D cross sections, bit by bit, the new device relies on a phase change to build a 3D object with a single shot. "It's one of the first...
Copper nanoparticles, green laser light cost beneficial in circuitry printing

Copper nanoparticles, green laser light cost beneficial in circuitry printing

Science
Sept. 13 (UPI) -- Printing electronic circuitry with copper nanoparticle ink and green laser light can be more cost beneficial and efficient, according to a study. Researchers at Soonchunhyang University in South Korea studied the thin-film printing technique instead of the conventional methods, based on laser power, scanning speed, pre-baking conditions and film thickness effects. Their findings were published this week in the journal AIP Advances. Nanoparticles in metallic inks have an advantage over bulk metals because of their lower melting points in the circuitry manufacturing. Originally the researchers, led by Kye-Si Kwon, tested silver nanoparticle ink but found it is costlier. Then, they studied studied copper, which is derived from copper oxide. Although copper's melting point ...

Shutterstock photo3D printing promises no less than the possibility to treat the physical world of atoms like the virtual world of bits, allowing users to "email" all sorts of physical objects - that is, they can send validated specs to be 3D printed by a recipient with one click. In 3D printing, or "additive manufacturing," successive layers of material are added to create the desired object, which can be of almost any shape or geometry. There's still a perception that 3D printing is an expensive and overhyped way to manufacture cheap plastic toys, but the reality is that today's 3D printers can process a wide and increasing range of materials and complex designs.With comparatively low manufacturing costs - and no shipping costs - 3D printin...
