Just because you have a 3D printer doesn't mean you're going to make anything remarkable. It doesn't even mean you're going to wind up with what you set out to produce. Believe it or not, 3D printing requires some skill. And when you don't have it, things go delightfully askew.

While there are plenty of possibilities with a 3D printer, there's also just about as much room for human error. You can't let the printer get too hot. But it must be hot enough! And you don't want it to work too quickly. But it has to work quickly enough! You're going to mess up. But you're not alone. Here are some of great examples of some pretty egregious 3D printing failures:


Whistles that can't even whistle should be called something else.

This botched bust is supposed to be Walt Disney. Squint hard, and maybe you can kind of see it. (You can't).

Definitely don't try to use this 3D-printed glass as a glass if you have any desire to use it for drinking.

Here you see the makings of a starfish. Unfortunately, the machine ran out of material.

Bonus round: This iPhone shoe abomination isn't technically a failure, we're going to include it as a reminder of what NOT to do with a 3D printer. Because seriously, what the hell?
