3D Metal Printing

Researchers at Harvard have come up with a way to use LASERs to anneal silver nano-particle liquid into wire that’s thinner then a human hair.  This process allow them to eject the silver liquid through a needle and have a laser solidify it instantly to print 3 dimensional wire objects.  The video above is fun to watch.  Like all current 3D printing systems, this will have a few years of refinement needed before it’s ready for prime time, but it does usher in newer smaller more curvy electronic devices.  That sounds cool doesn’t it?

DIY Cheap 3-D

Stereoscopic images are a basic way to give you brain a perception of depth from a single 2-d photo.  However, it’s usually pretty difficult to get working without super expensive cameras and setups.

Well, Mathieu Stern discovered a cheap adapter called a Stereax on eBay for only $30.  With alittle modification to get the adapter to mount to a modern lens, he was able to make some pretty neat 3-D images with just his regular slr.  Now, stereoscopic images are supposed to be best viewed with crossed eyes, but most people are bad at doing that, so the other way of using PhotoShop to make an animated gif works to.  You get the depth perception there, and that’s usually good enough to get the idea.

3-D Printed Home

3D printed room

It’s coming.  At least in The Philippines anyway.  The Lewis Grand Hotel in Angeles City Pampagna has constructed a 1500 square foot 2 bedroom villa as an addition to their hotel.  Lewis Yakich, thw owner, is a material science engineer, and has spent many hours coming up with the processes necessary for this first of its kind endeavor.  The entire printing process took 100 hours, but was not continuous as you would expect from a typical 3-D printing process.  This is partly because plumbing and electrical components needed to be installed, but also because they were ever changing the and upgrading the machine as time went on.

Construction of the machine itself took 2 months, but now that all the kinks are worked out, he thinks it will only take a few weeks.  He even hopes to use his technology to 3-D print 2,000 rooms within 2 years.  With the efficiency of the technology getting better with each subsequent use, this is something that is not completely out of the question, but it is a lofty goal.

Check out the video of the machine in action:

I do think this is a cool process.  I like the idea, I think it could be improved upon though.  The rippled walls I’m not a fan of, but those can be stuccoed over, or sheet rocked, or something.  I think this entire process could be very useful for creating fallout shelters.  And radiation proof holdings.  You could fill them with water and make filters for some secret time-travel device.  If this technology progresses, I could see it being in use in a certain bunker that may or may not end up existing underneath some land that I may or may not end up owning in a state in the US in the future.  Hypothetically of course.
