New 3-D Printer Uses Light to Build Objects in Minutes

The next generation of desktop 3-D printers might do away with the excruciatingly slow process that current units use. Researchers have unveiled a printer that replaces the current extruder nozzle that squeezes out melted plastic one layer at a time with light and oxygen. 

The makers of the Carbon3D printer have demonstrated a technique they call continuous liquid interface production (CLIP), which grows 3-D printed parts out of a liquid resin bath. Ultraviolet light and oxygen work to build a stronger part in layers just tens of microns wide. Build times can be reduced from hours to minutes, they say.

Their work builds on the process called stereolithography, an additive manufacturing technique developed in the 1980s that builds parts layer by layer with liquid resin cured by light. 

“By rethinking the whole approach to 3-D printing, and the chemistry and physics behind the process, we have developed a new technology that can create parts radically faster than traditional technologies by essentially ‘growing’ them in a pool of liquid,” said University of North Carolina, Chapel Hill chemistry professor Joseph DeSimone, who coinvented the technique and is also Carbon3D’s CEO.

Octopus Citizen Science!

My labmate, Anne, is categorizing the body patterns of Octopus cyanea for her thesis project. Her work requires photographs and videos of Octopus cyanea. These images will be analyzed to answer questions about body pattern generation. You can help her by either sending her your photos and videos of Octopus cyanea, which is active in the day, and found in the Indopacific (including Hawaii)… or, if you really want to help out, go to the link below and score some octopus body patterns yourself: https://sites.google.com/site/bodypatternsofoctopuscyanea/home/interobserver-bias-scoring It takes a little time to figure out the instructions, but if you want to participate in octopus research, here’s your real opportunity!

Have fun, nerds! Share this with your friends!
