Slideshow: 3D Printing Multiple Materials, Colors & Textures Gets Closer
10/1/2013

The prototype Vista 3D inkjet print head can print metals, plastics, ceramics, biological cells, and enzymes. This ability is due to the print head's droplet ejection motion, which can print large particles of 50 microns and above, as well as viscous and volatile fluids. It is currently used in 2D printers and being adapted to 3D printers.(Source: TTP)

The software part as well as the adding up of materials seems more or less to be a solved issue.

What still remains a challenge is how to make diferent materials stay together with strong bonds. Probably there will not be a single universal "glue" capable of joining an organic tissue with a metal or with a polymer, and maybe that's were much of the future research (what "glue" and how to implement it on a 3D machine) will be directed to.

At first I thought that statement was hype. But since I began covering this subject in more depth, I agree with it. Actually, I think we're in a period where there's a lot of interaction and convergence among multiple technologies that have "evolved" to a certain point, combined with much more communication among people globally enabled by internet platforms like Kickstarter and Dragon Innovation, as well as partnerships between industry and university labs at MIT, Harvard, Caltech and Stanford, among others. It reminds me somewhat of the mid to late 90s when wireless plus handheld consumer electronics plus the Web were converging, but more so because of entrepreneurs and Kickstarter.

Yes, I agree, Ann, the technology itself is fascinating enough, but the potential for it is even more amazing. When people talk about 3D printing as potentially being as disruptive as the Internet, I think they may be on to something.

Since I'm not designing products, I think the main thing that still attracts me is the magic box "wow" aspect, and that's been true since I saw photos of the first SLA demo by 3D Systems back in 1988. But I'm also intrigued by what all this can do for design engineers and manufacturing OEMs.

Haha, your enthusiasm for the technology is contagious, Ann. I feel the same way, even though I've never experienced it up close and personal, and I wish I had the money and technical knowhow to take advantage of some of these new innovations!

Chuck, interesting idea.

Totally, TJ! At least that's sure true right now. A lot of today's wild and crazy tech was first dreamed up back when it seemed so unlikely to ever be realized. Makes me think many more sci-fi fans have been engineers than I ever dreamed, don't you think?
And didn't you mean replicators? :)

I agree, TJ. This might be one of the those rare situations in which technology migrates up, instead of trickling down.

Great slideshow, Ann. It's pretty incredible how quickly this technology is moving ahead.

The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team 100 to make (about $161 US).
A tiny humanoid robot has safely piloted a small plane all the way from cold start to takeoff, landing and coming to a full stop on the plane's designated runway. Yes, it happened in a pilot training simulation -- but the research team isn't far away from doing it in the real world.
Some in the US have welcomed 3D printing for boosting local economies and bringing some offshored manufacturing back onshore. Meanwhile, China is wielding its power of numbers, and its very different relationships between government, education, and industry, to kickstart a homegrown industry.
