3D Bioprinting Saved by Vitamins

Researchers developing techniques to 3D print extremely small objects for medical purposes have had a problem. To fuse material at the nano scale, a “two photon” technique is used. The material becomes solid when exposed to the targeted photons.    However, bio material is not typically fusible, so researchers often print a scaffold on which… Continue reading 3D Bioprinting Saved by Vitamins

3D Printed Horseshoes Opens Up Human Possibilities

Researchers at Australia’s CSIRO have 3D printed metal horseshoes – but there’s a lot more to this story.    The titanium shoes were produced for a particular horse: its hooves were 3D scanned in detail with a handheld scanner. The 3D capture was used to engineer new horseshoes that fit the horse perfectly. Four shoes… Continue reading 3D Printed Horseshoes Opens Up Human Possibilities

Measured: 3D Printing is Indeed Green

A report from Michigan Tech details the results of a study that attempted to determine the “greenness” of 3D printing. Their result: 3D printing is apparently significantly less energy-absorbing than conventional mass production.    You wouldn’t think so at first, because mass production is clearly a more efficient process due to the economies of scale.… Continue reading Measured: 3D Printing is Indeed Green

Big Step to Reduce Materials in 3D Printing

One of the reasons 3D printing remains expensive is because so much material is required to create a structurally sound part. Soon, 3D prints might be getting cheaper due to a new technique that enhances a part’s structure while reducing material.   A paper written by researchers at the University of Science and Technology of… Continue reading Big Step to Reduce Materials in 3D Printing
