The speed, geometry and quality assumptions are superior to advanced manufacturing processes related to the reliability of their product-based reassurance, says new researchers at UC Berkeley have been developed for printing items 3D.
Instead of building a level on its & # 39; cover, the Berkeley AM mode will print all points within a 3-dimensional item by copying; illustrate the smooth measurement of illustrated material with lightning changing patterns. (Click here to read a story The Progress Report posted to a "all-at-one" 3D printer that was developed at the Lawrence Livermore National Laboratory.)
According to Berkeley's researchers, the methodology, Complicated Axial Spelling (CAL), which allows us to go to # 39; synchronization of accurate geometry strictly through photopolymerization. "
The CAL engineer, with the "Replicator" with the engineers, can selectively optimize energy within a dimension. Light energy is delivered to measure material as a set of 2-layer images. Each projected image will move through the material from a different area. The increase of exposures from multiple angles gives enough 3-dimensional energy dishes to strengthen the material in the geometry needed. CAL is also capable of larger tweed sizes, and a number of commands of size are reported faster than the sidewalks.
With CAL, researchers can print features as low as 0.3 millimeters in acrylate polymers, as well as to print soft structures with a laptop with a smooth, using gelatin to hydrogel stacking.
3D printing structures are about the strong components that are already possible by Replicator as well, and the crew has the printer used to create a series of items, including a small model of "The Thinker" Rodin and a normal jawbone model. At present, the device can make up to 4 inches of diameter.
The technology is capable of converting the design and production of products, from insects to eyeglass lenses, which researchers say.
"I think this is a way to be able to convert more issues to a greater degree, whether they are strokes or running shoes," said Hayden Taylor, a professor engineering engineering at UC Berkeley and a senior paper author who describes the printer. "Given that you can take a metal part or something from another manufacturing process and add to the current geometry, I think that can change the way the products are designed," said Taylor.
