Unmanned aerial vehicle manufacturers such as Honeywell are using 3D laser sintering to make a multitude of parts and subsystems, including engine housings, fuel tanks, and fuselages. The vehicle, its parts, and its payload can be changed quickly for different customers or different missions. Paramount, a 3D Systems company, has made parts for Honeywell's T-Hawk Micro Air Vehicle. The British Army has adopted the T-Hawk MAV for use in Afghanistan, and the US Army is using it for its Future Combat Systems Class I UAV. The parts are made with Paramount's high-temperature laser sintering process. Its materials can be processed at 380 C, are naturally nonflammable, and don't outgas. (Source: Honeywell)
My initial thought about using the prototype materials was the thermal risks; meaning brittleness and prone to shattering in the extreme cold Martian temperatures. But I recalled a recent environmental test done to an SLS prototype housing. It was placed in a cold chamber at -55°C and an impact test was run, simulating a sharp impact at extreme cold. The housing was designed with a 2mm wall thickness, and the SLS didn't even dent, let alone shatter. And while Martian climate can exceed -55°C, that was the lowest limit of our chamber's capability. But I'm convinced; at least for SLS.
Jenn, Contour Crafting's potential blows my mind. I mean, 3D printing whole buildings? It's still under development and started out as a mold-making technology for constructing large industrial parts. The inventor expanded the concept to a method for building quick emergency shelters after disasters, such as Hurricane Katrina or major earthquakes. The website says it can produce structures such as houses or larger multi-unit buildings, and that "embedded in each house [are] all the conduits for electrical, plumbing and air-conditioning." That's amazing enough, but the process is also designed to use naturally occurring local materials like clay or plaster. That's a big one--no expensive engineering-grade plastic needed. Here's the inventor giving a TED talk: http://www.youtube.com/watch?v=JdbJP8Gxqog
Yes Beth, I agree. It seems like a month or so ago we were talking about similar things and now here they are here. It just begs the imagination to think about 2 years from now or 5 or even 1 year. I knew this would be big, but it's blowing up!
Defintely out of this world examples of 3D printing. Very cool that this technology is playing a role in space exploration. It really confirms how far the materials have come in terms of choice and durability/reliability that they are even an option for such serious engineering.
Many of the new adhesives we're featuring in this slideshow are for use in automotive and other transportation applications. The rest of these new products are for a wide variety of applications including aviation, aerospace, electrical motors, electronics, industrial, and semiconductors.
A Columbia University team working on molecular-scale nano-robots with moving parts has run into wear-and-tear issues. They've become the first team to observe in detail and quantify this process, and are devising coping strategies by observing how living cells prevent aging.
Many of the new materials on display at MD&M West were developed to be strong, tough replacements for metal parts in different kinds of medical equipment: IV poles, connectors for medical devices, medical device trays, and torque-applying instruments for orthopedic surgery. Others are made for close contact with patients.
New sensor technology integrates sensors, traces, and electronics into a smart fabric for wearables that measures more dimensions -- force, location, size, twist, bend, stretch, and motion -- and displays data in 3D maps.
As we saw on the show floor this week at the Pacific Design & Manufacturing and co-located events in Anaheim, Calif., 3D printing is contributing to distributed manufacturing and being reinvented by engineers for their own needs. Meanwhile, new fasteners are appearing for wearable consumer and medical devices and Baxter Robot has another software upgrade.
