10 ways 3D printing is positively impacting the world Additive Manufacturing

by Architecture

For the past several weeks, 3D printing has been making headlines around the world, and primarily in the United States. To the frustration of most of the industry, this significant media attention has been grabbed by the ever-notorious 3D printed gun debate, re-ignited by the U.S. government’s recent decision to legalize the proliferation of 3D printable gun files. “A 3D printed gun is downloadable death,” reads a CNN headline by actress Alyssa Milano. “Newly-legal 3D printed gun blueprints are a looming catastrophe,” reports the Telegraph.

3D printed titanium spinal cages beat PEEK cages in new animal study Medical

by Medical

Stryker’s Spine division today announced the publication of a pre-clinical animal study comparing the performance of spinal implants made from a variety of materials, which illustrated the bone ingrowth and biological fixation capabilities of its 3D-printed Tritanium cages. The study, titled “Bony Ingrowth Potential of 3D Printed Porous Titanium Alloy: A Direct Comparison of Interbody Cage Materials in an In Vivo Ovine Lumbar Fusion Model,” was published in the July issue of The Spine Journal.

NASA 3D-Printed Habitat competition selects top 5 teams Aerospace

by Architecture

Beginning in 2014, the NASA 3D-Printed Habitat Competition has been challenging teams from around the world to propose effective solutions for colonizing the red planet through robotic building systems (which are now generally understood to be different types of 3D printers). After two stages where NASA awarded a total of over $1 million to competitors, the final prize was awarded to the top 5 projects.

Fabrisonic and NASA 3D print interplanetary heat exchangers Aerospace

by Aerospace

In 2014, NASA’s Jet Propulsion Laboratory (JPL) awarded Ohio-based Fabrisonic seed funding to develop its hybrid Ultrasonic Additive Manufacturing (UAM) process for improved metal heat exchangers. With continued support from JPL over the years and with in depth development and testing, Fabrisonic has successfully developed pumped fluid loop heat exchangers which are lighter, more efficient and faster to produce than traditional epoxy tube heat exchangers.
