NASA aborts testing of 3D printed space shuttle engine
A team from NASA’s Stennis Space Center rocket testing facility in Mississippi has aborted tests of its Aerojet Rocketdyne RS-25 space shuttle engine – manufactured using SLS. The test intended to run for a flight duration of 500 seconds to evaluate the performance of a new main combustion chamber (MCC), however, an early cut was issued at 319 seconds due to a “facility issue.”
Nevertheless, according to Stennis Space Center, the objectives of the engine test regarding fuel propellant conditions were achieved before the early cut of the launch. Another test will take place in September.
In other news, Autodesk has partnered with NASA’s Swamp Works laboratory in Florida, to develop 3D printed human-habitable structures made from lightweight regolith, a sediment found on Earth and the Moon.
“Additive manufacturing technology has the potential to revolutionize the way we do construction here on Earth,” said Massimiliano Moruzzi of Autodesk’s computational science research group.
“If we can repurpose plastic pollution and use readily available natural resources to robotically print houses on Mars, we can use the same approach to sustainably build streets, sidewalks, and even playgrounds here at home.”
3D printed bus shuttle Olli arrives at University at Buffalo
“We are pleased to partner with the University at Buffalo and the State of New York to implement and customize Olli for their mobility testing and sustainability strategies,” said Matthew Rivett, Executive Vice President of Local Motors.
“This partnership showcases how campuses, states, and others can invest in and explore the future of transportation. Local Motors looks forward to assisting UB and future partners on practical solutions and research opportunities for mobility challenges.”
ZARE installs Italy’s first 3D Systems ProX SLS 6100 3D printer
3D Systems has announced that ZARE, an Italian service bureau, is the first in the country to install its ProX SLS 6100 3D printer. This printer is designed to produce heavy-duty prototypes and production parts from a range of industrial-grade nylon materials.
ZARE expanded its CNC machining services with additive manufacturing in 2009, and now solely offers additive manufacturing solutions to its customers. After viewing the ProX SLS 6100 at the Formnext 2017 exhibition in Frankfurt, Germany, ZARE worked with 3D Systems’ Italian channel partner 3DZ on the purchase and installation.
“The ProX SLS 6100 is a perfect solution for businesses like ZARE that need to produce highly accurate parts with excellent surface finish that can withstand the rigors of daily use,” said Andrea Simeoni, CEO at 3DZ.
PyroGenesis reveals powder performance results from undisclosed OEM
PyroGenesis, Canadian manufacturers of spherical metal powders for 3D printing, has announced that its TI-6AL-4V grade 23 titanium powder has “met or exceeded rigorous properties requirements under intensive chemical and mechanical analysis” carried out by an undisclosed 3D printer OEM.
The undisclosed OEM, whose name remains confidential for competitive reasons, is now discussing commercialization strategies with PyroGensis. This may lead to the OEM becoming an approved supplier of the TI-6AL-4V grade 23 titanium powder for its end-users.
“This is indeed an incredible milestone and achievement when considering the short amount of time from when PyroGenesis announced it was re-entering the powder production business,” said Massimo Dattilo, Vice President Sales of PyroGenesis.
“Of note, this is not the only printer OEM we are in discussions with. We have made significant inroads to being approved on other printer types as well, and we look forward to making additional announcements as events unfold.”
CGTrader 3D model marketplace accumulates 1.5 million members
CGTrader, a 3D model marketplace based in Vilnius, Lithuania, has reached 1,500,000 members, a six-fold increase since 2015. CGTrader has attributed this milestone to the increasing amount of Fortune 500 companies and 3D designers joining its community on a daily basis.
“With each day we are becoming a massive force that is changing the 3D industry for the better. We strive to be the most designer-friendly 3D marketplace in the world for designers, while at the same time we are attracting customers from over 180 countries,” said CGTrader in a recent post.
Renishaw graduate scheme gains national recognition
The Graduate Scheme is a two-year program which trains students in eight different divisions of the company, including additive manufacturing. The graduate employees then have the option to take on a permanent position at the end of the scheme.
“Renishaw’s graduate scheme is a challenging, rewarding opportunity that offers the potential for rapid progression,” explained Sam Bishop, Learning and Development Advisor at Renishaw.
“The company’s CEO, Will Lee, joined Renishaw as a graduate in 1997. A position at Renishaw can take you almost anywhere in the world, working in industries as diverse as neurosurgery to additive manufacturing.”
Renishaw was also ranked 42nd overall in the top 100 graduate schemes across all sectors.
3D printing applications
Researchers on the MAS Digital Fabrication team at ETH Zurich, who created an experimental metal facade using 3D printed sand molds, have fabricated an 80m² lightweight concrete slab using the same process. Dubbed by its creators as the “Smart Slab”, this 80m2 lightweight concrete block is said to be the world’s first full-scale architectural project to use 3D sand printing for its formwork.
In other news, artist and architect Tobias Klein has published a research paper titled “Augmented Fauna and Glass Mutations: A Dialogue Between Material and Technique in Glassblowing and 3D Printing” which explores digital and traditional craftsmanship.
Betatype, additive manufacturing technology developers based in London, and Progressive Technology, CNC machining specialists based in Berkshire, have produced 384 automotive headlight components within a single build using metal laser powder bed fusion (LPBF).
In its case study, Betatype demonstrated its optimization technology to produce cost-effective automotive part while drastically reducing lead times from 444 hours to 34 hours.
