News & information about the fast-moving world
of digital manufacturing, modeling & simulation
April 02, 2012
Rebecca’s Vette is Fixed!
You may recall that back in December, I wrote about the challenges facing me and my beloved Corvette. I was in dire need of a relatively simple part – a tray that secures the engine computer had broken and I was at a loss finding a replacement for my vintage beauty. In my grief, I wondered out loud why there wasn’t anyone out there that did made-to-order parts using direct digital manufacturing or alternatively, if there were, why couldn’t I find them?
I received an outpouring of support; most responses sympathized with my plight and shared their own challenges of procuring outdated parts. How many people really need a window crank handle these days? But, alas, our readers couldn’t point me to anyone out there that could scan and build one-off parts as a service. There must be a need for this. I know there’s a need for this because I had a need for this.
It’s one thing when a car breaks down, when it throws a rod or you score a piston or something serious happens. But my noble steed was off the road because of a tray. And there was nothing I could do to fix it. The knowledge that spring’s coming early to DC loomed. Missing out on prime, top-down, cherry-blossom convertible season because of a tray? It was heartbreaking.
Enter Stratasys, Inc.
Stratasys, located in Eden Prairie, MN is a builder of 3D printing machines that use additive manufacturing technology to build functional prototypes and production parts layer-by-layer using industrial-grade thermoplastics.
Noah Zehringer, a Senior Application Engineer at Stratasys, reached out to save the day: while their AE team doesn’t offer a reverse engineering service per se, they often help customers with engineering challenges. To my delight, their machines are able to accommodate almost any size, geometry or complexity in printing parts. Noah asked that I send him the broken part and he would see what could be done.
Back at the lab, they redesigned the part in 3D CAD software to create a printable file. Then they sent the file to their Fortus 400mc 3D Production System. In just a few hours, my tray was complete, built in Ultem, a material with high resistance to heat and chemicals, plus high tensile and flexural strength – perfect for what I needed – a custom-made part with no tooling, no machining, no hassles. My heroes.
I don’t particularly enjoy the whole “damsel in distress” role this broken part for my beloved chariot put me in. But honestly? I am not ashamed to say that Stratasys, and particularly Noah, came to my rescue – my Knights in shining (3D Printed) armor. Were it not for this talented team and their state-of-the-art technology in direct digital manufacturing, I would still be trapped in the tower rather than enjoying the purr of my classic piece of American history.

Aircraft Mock-ups Emerge from Gulfstream’s 3D CAVE
Simulations may be increasingly taking advantage of HPC to become more and more sophisticated, but the way those mountains of data are displayed don’t always keep up in terms of staying on the cutting edge. But one avenue for reviewing digital designs, called a cave automatic virtual environment (CAVE), looks to be making up for this trend by combining engineers’ modeling information with virtual reality.

Understanding Fluid Flow in Microchannels
The ability to control fluid streams at microscale is of great importance in many domains such as biological processing, guiding chemical reactions, and creating structured materials. Recently, it has been discovered that placing pillars of different dimensions, and at different offsets, allows fluid transformations to “sculpt” fluid streams.

Floodgates Open for the Industrial Internet
So far, the story surrounding the industrial Internet has been centered around GE, and their plans to infuse their factories with thousands of sensors that will bring big data to manufacturing. But after record-breaking floods from Hurricane Sandy took their toll on New York and New Jersey, environmental and civil engineers have found a new application for the Internet-connected sensor system.

Short Takes
3D-Printed Airway Saves Life
May 23, 2013 |
In the wake of plastic gun stories, a unique use case for 3D printing helps demonstrate that the additive manufacturing technology's potential to save lives deserves its own place in the spotlight. Now, doctors at C.S. Mott Children's Hospital in Ann Arbor have combined medical expertise with 3D printing's flexibility to save a three-month old.

MIT Improves Carbon-Fiber Composites
May 22, 2013 |
While advanced carbon-fiber composites have been used in the recent years, researchers are searching for materials that are even stronger and lighter. Composites made with carbon fibers coated with carbon nanotubes are being considered because they can be hundreds of times stronger than steel and only one-sixth the weight.

NASA to 3D Print the Future of Food
May 22, 2013 |
NASA has awarded a $125,000 grant for a project intended to 3D print food for astronauts in space. The printer will mix together basic nutrients such as oil and protein powder to create the food. It will also allow the user to input their sex, age, and weight so that it can make the food based on the individual's own nutritional needs.
