3D Printers

I read this article about a 3D printer that was recently unveiled at the Consumer Electronics Show and couldn’t help but get a bit excited.  Sure, as the article points out, at $1300, this “affordable” printer may not be affordable for everyone.  (It’s not for me.)  But it’s getting closer to affordable.

The notion of being able to create or download a 3D image file on my computer, send it to the printer via a USB cable, and have the real object in my hand a few minutes (or a couple of hours) later is pretty amazing — and I’m not even in a business that does any rapid prototyping, nor do I have a burning need for my own custom designed neon ABS plastic chess set, two of the most often cited uses for such a device.

The best part will be watching the prices come down on these.  They are a bit expensive now, but in five years, I could see myself forking over $500 for something like this.  Especially if the media that is “printed” comes down in price as well.

I’m sure, in addition to being a fun, novel tool with which to experiment, I could find more and more uses for it once I had one.  Kids break one part of their favorite toy?  Make another!  This gadget were exactly the same but with a built-in loop for hanging it from a hook?  No problem!  Like something I have?  I’ll scan it and email it to you and you can print one for yourself (almost) instantly!  It’s a pretty exciting future.

Edupunk: Lego Printer

It’s a bit random, but this YouTube video of a DIY Lego printer was recommended to me by a friend.  (Thanks, Lorrie!)  It’s not directly related to ESL, but it would probably give your students something to talk about.  I’ve always enjoyed seeing projects like this ever since building a $50 Interactive Whiteboard.  With the rise of Instructables.com and other open source and DIY sites, it’s amazing what people are able to build for themselves.  Having a team of Lego people “controlling” the printer is a really nice touch.
