Some of the Coolest Things You Can 3D Print

• Camera And Lens You can 3D print a fully-functional SLR camera in 15 hours. Assembly, with instructions, takes just one hour. The camera is capable of taking quality pictures and is compatible with any photographic lens. If it's too tantalizing to have a near-complete 3D printed camera, you can actually print a lens, too. The picture quality isn't great, but then again it can give you some really cool effects.

• Custom Busts With that new 3D printed camera and lens, you'll be able to take some stunning portraits. But 3D printing lets you up the ante: you can print accurate busts and figurines of yourself, your family, and your friends.

• Bike Hacks(Bottle Mount, Valve Cap) If you're into bike customization, 3D printing is a goldmine. Here are some highlights: a mount to make a plastic bottle fender, abike carrying handle, or personalized valve caps. And the imagination needn't stop there.

• Musical Instruments They aren't exactly professional quality, but the fact that we can 3D print instruments at all is astounding. So far, we've seen flutes,violins, and guitars. In addition, the MIT researchers who printed the flute have bigger dreams: designing and 3D printing previously unfathomable instruments, like a multi-pipe trumpet.

• Gadget Upgrades Another plethoric realm of 3D printing is gadget accessorization. There are countless examples, but here are a number of beauties: clever iPad stands, multi-purpose iPhone cases, an iPhone wall mount for charging, andgear wraps for your malicious, ever-tangling cords.

• Phone Amplifiers(Megaphone, Amplifier) No one actually enjoys the sound quality of their phone's built in speaker. Sure, it can come in handy for sharing videos with friends, but as an actual attempt to listen to music it tends to only come out in dire situations, like overnight camping or power outages. But you can change that with amplification, as these 3D printed upgrades do. There's a classy megaphone or this more directed amplifier, and the accompanying video demonstrates the difference that it makes.

• Flying Things(R/C Sailplane, Quadcopter, Gliders) Paper airplanes are passé: Print out some gliders and go to the biggest field you can find, and give them a whirl. If you're looking for something with a little more firepower, you can print out the body for a crazy remote-controlled sailplane.

• Vacuum Forming Machine You can 3D print necessary parts for a vacuum former. And a 14-year-old designed it. This product would allow you to create molds of practically anything, then fill them with chocolate (or urethane). Just imagine the power.
