Got Loose Change? 104 Pennies Help This Simple 3D-Printed Toy Walk

Invented in 1981 by John W. Jameson, the Walking Gyro is a simple toy that relies on a spinning flywheel and centrifugal forces to take tiny, but steady, steps. Mattel patented the design, but never actually put it into production. And now that its patent has expired, there’s a free 3D-printable version that anyone… » 7/17/15 11:22am 7/17/15 11:22am

A New 3D Printing Support Filament Easily Dissolves Away in Water

When 3D printing a particularly complex object, you often need to incorporate additional support structures into its design, given how the layer by layer additive process works. And with 3D systems new water soluble filament, those unwanted support structures can easily be dissolved away with a little H2O. » 7/14/15 11:50am 7/14/15 11:50am

The Only Way To Describe This 3D-Printed Mechanized Toy Tank Is Amazing

If there’s one thing a plastic resin 3D printer is good at, it’s making custom toys. And Michael Sng’s Machination Studio has created the ultimate example of what 3D-printed toys can be with the HMC Boudicca; a 20-inch tall walking mechanized tank with more detailed animated features than even R2-D2 has. » 7/02/15 9:27am 7/02/15 9:27am

3D-Printed Flutes Can Produce Notes that Regular Flutes Can't

3D Printing has been around long enough for playable 3D-printed instruments to exist, but most musicians will still opt for one made using traditional methods. That could soon change, however, as researchers have found a way to design and 3D print musical instruments capable of producing unique notes that traditional… » 6/18/15 6:40pm 6/18/15 6:40pm

These Impossibly Twisted 3D-Printed Faucets Somehow Actually Work

Besides being able to produce prototypes quickly and efficiently, 3D printers are also able to create complex shaped pieces that are impossible to make using traditional manufacturing techniques. That’s why American Standard has embraced 3D-printing for its new line of twisted faucets that seem physically impossible. » 6/18/15 3:40pm 6/18/15 3:40pm

Watch how 3D printers 3D print 3D printer parts to make more 3D printers

Like how some animals can regenerate limbs or like how humans can, uh, make babies, 3D printers can 3D print the 3D printer parts necessary to make more 3D printers. Thankfully, they still require some living person to put these parts together because if they didn’t, they could just start eliminating us one by one as… » 5/27/15 12:55pm 5/27/15 12:55pm

3D-Printed Eggs Can Even Fool Wild Birds Into Thinking They're Real

Maybe you’re familiar with the asshole behavior of cowbirds. Known as “brood parasites,” cowbirds lay eggs in another bird’s nest and trick the host bird into raising cowbird offspring at the expense of her own. Like I said, assholes. But birds can learn to recognize imposter eggs. That’s where 3D printing comes in. » 5/26/15 1:40pm 5/26/15 1:40pm

3D Tissue Engineering May One Day Solve Both Impotence And Miscarriage

A study published last week in the journal Biofabrication describes a new technique to build replacements for damaged three dimensional human tissues. The researchers running the study are trying to make an eardrum. But their technique, if successful, might also one day create replacements for complex reproductive… » 5/14/15 6:50pm 5/14/15 6:50pm

This Goo Accurately Paints Patterns on Your 3D-Printed Creations

If you try to describe 3D printing to someone, you can’t help but channel a little science fiction. “You put designs in this machine, which then just like...makes it.” I’m convinced that its the great-great-great-grandfather to the oft-referenced Star Trek replicator. Luckily, I already like my tea Earl Grey and hot. » 5/13/15 6:40pm 5/13/15 6:40pm
