Enabling Research Through AM (Authentise Weekly News-In-Review – Week 01)

Hi everyone, welcome back to the new year with a more weekly 3D printing news from Authentise!

Through AM scientists are able to go where traditional manufacturing simply couldn’t take them. NASA is keeping up the pace for the entirely 3D printed rocket by testing more and more components up for the challenge, ROSCOSMOS is planning to add a bioprinter to the ISS’s arsenal and test it at microgravity and, while we’re at it, stem cell research is getting a boost from 3D printing’s ability to create cartilage’s structures.

Are you aching for your daily fix of science with a side of AM? Let’s dig in.

NASA Engineers Test Combustion Chamber to Advance 3-D Printed Rocket Engine Design

Recent tests of a developmental rocket engine at NASA‘s Marshall Space Flight Center in Huntsville, Alabama, produced all the performance data engineers were hoping for, along with the traditional fire and roar. But this engine is anything but traditional. Marshall engineers are designing each of the components from scratch to ultimately be made entirely by AM methods …The series of 12 test firings in late fall brought them a big step closer to that goal, said Andrew Hanks, test lead for the project. The fuel turbopump, fuel injector, valves and other major engine components used in the tests were 3D printed, with the exception of the main combustion chamber.

Russian space agency Roscosmos to 3D print living tissue on ISS

Russian scientists are planning to install and operate a 3D bioprinter aboard the ISS, according to an official source. They believe that microgravity conditions could actually improve the bioprinting process. […] They believe that significant progress in bioprinting can be achieved by placing equipment in microgravity conditions, since the lack of gravity could potentially help to keep deposited cells in place.

Scientists Are Creating New Ears With 3D-Printing and Human Stem Cells

Inspired by the earmouse, doctors at the University of California at Los Angeles and the University of Edinburgh’s Centre for Regenerative Medicine have perfected a new technique to grow a fully formed human ear, using patients’ own stem cells. They begin with a 3D printed polymer mold of an ear, which is then implanted with stem cells drawn from fat. As these stem cells differentiate into cartilage, the polymer scaffold degrades, leaving a full “ear” made of mature cartilage cells. The new approach could “change all aspects of surgical care,” says Dr. Ken Stewart, one of the researchers and a plastic surgeon at the Royal Hospital for Sick Children.

Week in Review: November 22nd to 27th – Collaborations Driving 3D

Hi and welcome to another Week-in-Review!

This week there is a treasure trove of evidence that partnerships and collaborations really do make a difference and show a rapidly maturing industry. This week’s examples go full spectrum: Renishaw and Dassault bang brains together trying to solve AM design and optimization issues, a collaboration between Auburn U and Nasa seeks to push the limits of space exploration even further through AM creating and another collaboration has designed and printed the best golf driver in the world.

Renishaw is collaborating with Dassault Systèmes, a world leading 3D modelling, simulation and industrial operations software provider, as part of its commitment to provide and enhance software for metal additive manufacturing (AM). “The 3DExperience platform coupled with QuantAM enables parts to be produced accurately from the outset, which is of tangible time and cost benefit to users. It marks the beginning of many enhancements we have in the pipeline to improve the AM user experience and streamline the front-end of the manufacturing process” explained Stephen Anderson, Renishaw’s Director of Group Software.

Auburn University and NASA sign Space Act Agreement on additive manufacturing

Lab

John Mason, Auburn’s vice president for research and economic development, recently signed a Space Act Agreement with Patrick Scheuermann, director of NASA’s Marshall Space Flight Center in Huntsville to explore additive manufacturing applications using metals, polymers and ceramics. “Great partnerships like this will help us get to places where we’ve never been before,” Scheuermann says. “We can make rockets like our predecessors did . . . but it’s really important to infuse additive manufacturing so that the Space Launch System is affordable and sustainable for decades to come.”

Race car manufacturer, CRP Group and golfing manufacturer, Krone Golf have combined additive manufacturing and subtractive manufacturing techniques to craft what they believe is the world’s most advanced golf driver. The KD-1 is the first Windform SP 3D-printed driver clubhead with CNC machined titanium hitting surface. It is a composite driver clubhead where the different materials have a specific function and structural competence.
