This field is about to EXPLODE!! Seriously, explode like a bomb. It's going to be equivalent to like the smartphone. Why do I think this? Well, imagine being able to create almost anything you ever dreamt in a matter of a few minutes. Want a new cutting board? Go print it. Oh no! Your phone case broke? Go print it. The handle on your toilet snapped off? Go print it. Seriously, anything you would ever need could be printed right in the comfort of your own home.
Here's one now. Look at its beauty! You can see that this one just finished printing a toy car. Just look at it for a minute. What do you think its made of? Well, there are actually a lot of different methods out there. They usually lay down successive layers of liquid resin or metal, powder, or sheet material successively so that that each layer will form a small bit of whatever you're printing. Now, what's really cool is how it knows what you want to print. You go into a computer program and design your object and simply upload it into the printer, and bam! You now have yourself whatever you want printed.
These wonders aren't just restricted to solid plastic objects, they can actually go as far as to print food. Yes, food. You may not be able to print like a whole turkey yet, but something like chocolate? That's easy. Put some melted chocolate into the printer and have it print a bunny. Maybe in a few years you'll get your turkey, but what you can do so far is still pretty sweet.
So, why hasn't the market exploded with these printers? Simple. There are key patents out there that restrict them from being produced cheaply, but there's some good news! Those patents will expire in 2014, so like I said earlier, they will EXPLODE!! So my suggestion? Go to the stock market and invest in major 3D printing companies before the turn of the year. Hopefully, you'll make some big dollars!
