A 3D-printed house? What about a store that 3D prints you a custom shoe? And will we be able to, one day, 3D print our way to Mars? It's all possible!

3D printers have to be one of the coolest pieces of technology affordable enough to have in your home. While 3D printers have been around since the 1980s, it wasn't until the last 10 years that one could find affordable 3D printers to own.

And while many of the 3D prints that made our list require industrial-quality 3D printers, many could be reproduced by anyone with an at-home 3D printer.

How does a 3D printer work?

So how is it possible to make all of these incredible things? Briefly, a 3D printer uses a "sliced" design to print objects in 3 dimensions. The slices are essentially thin slices of an object that the 3D printer creates by extruding heated plastic filament that is then cooled and hardened. All of these slices combine, layer by layer, to create something cool.

If you're looking for more information, we encourage you to check out our 3D printing FAQs, where we dive deep into what makes 3D printers tick.

We've been building the cars the same way since Ford first put workers on an assembly line more than 100 years ago. There are still thousands upon thousands of tiny parts that come together to make a driving machine. But does it need to be that way?

Strati 3D printed car

Nope! At least not according to Local Motors CEO Jay Rogers, who has made a completely drivable 3D printed car known as the Strati, using an industrial-grade 3D printer. These city cars could end up costing as little as $5000, which makes them very affordable.

3D printed food
Pinterest

If you're a fan of Star Trek, then you'll remember the replicator they would use to make just about any food dish instantly. Many of us thought that that future was way off, but it's not. It's here. Well, it's almost here.

3D printed food
Pinterest

The attempts at 3D printing food are still...well...sometimes less than appetizing. But the potential this has is hard to fathom. Imagine the ways that 3D food printers could work to solve world hunger. It's pretty incredible.

3D printed soup

Some of the best attempts at 3D printing food we've seen have been with recipes that are naturally blended, like soups or plates of pasta. Some gastronomy experts are doing some pretty aesthetically (and tasty) things with the very modern cooking method, like this beautiful split-pea soup.

3D printed drone

If drones are the future (and we suspect they are), then drones that are easily reproducible and cost-effective will change the way explore our environments. And yes, we think that a science-fiction future full of drones and other cool things isn't too far away!

3d printed mini drone

Make your own

There are loads of schematics available for 3D printed drones on Thingiverse, such as this mini 3D printed drone. You'll obviously need some other parts to make the drone come to life, like a power supply and a video transmitter. You also have the option to customize the schema to your liking!

3D printed prosthetic leg
Pinterest

When innovation fulfills a need for those in society faced with difficulties, then something extraordinary can occur. Prosthetic limbs can cost tens of thousands of dollars, and many people struggle to afford them. 3D printing allows open-sourced, low-cost alternatives to traditionally pricey prosthetics.

3D printed prosthetic arm and hand

One such nonprofit is Enabling the Future, which offers free or low-cost 3D printed designs for upper-limb prosthetics to those in need. There are also various easily customizable, free designs available on Thingiverse.

3d printed theatre set
Pinterest

It's not over until the 3D printer sings! 3DWasp recently designed a set used in the opera Fra Diavolo at the Opera Theater in Rome, Italy. Once the basic backdrop was printed and set up, the lighting engineers simply projected images throughout the production to mirror the changes in the scene. We think the results are pretty incredible and really show how innovative you can be with 3D printing!

3D printed medical equipment
Pinterest

We've seen recently how shortages of life-saving medical supplies can happen quickly. Hospitals and medical supply companies are looking for new, innovative ways to make supplies quickly when a disaster strikes. 3D printing might be the solution, allowing hospitals and other facilities to 3D print a piece of equipment when supplies are low.

ReFabDar Design Contest

The Nonprofit organization, ReFab Dar, is hoping to use 3D printing to create vital medical supplies in Africa and other developing countries. They've recently run a contest that challenged African designers to create medical-based designs that would make use of the recycled bottles piling up at a nearby plant. We can't wait to see what other innovative things can be done with recycling once it becomes more cost-effective.

RepRap project self-replicating 3D printer

This one might make your head spin! But what if you could 3D print a 3D printer, and then 3D print another 3D printer with that one. Would the universe implode?! Maybe.

self-replicating 3D printer

While many 3D printers are capable of self-replicating in theory, like the Prusa i3 we've reviewed, one of the most famous projects to make this happen is the RepRap project. The project, out of the University of Bath, aims to find innovative ways to self-replicate 3D printers.

There are even options designed for self-watering and draining. We've certainly come a long way since the days of clay.

3D printed heart organ

What if you could 3D print a custom heart to save someone's life? We're getting remarkably close to that. Studies have shown promise when it comes to 3D printing human tissue. The process is known as 3D bioprinting and is currently being used to print capillaries and other smaller parts of organs.

3D printed skin graft

Another organ that's showing promise in the 3D bioprinting industry is skin. (Yes, the skin is an organ!) The ability to 3D print a full skin graft could save the lives of thousands of individuals who wait for a skin graft. It's seriously amazing!

3D printed Boat
Pinterest

Behold the 3Dirigo—the world's largest 3D printed boat! The project, backed by government funding, was designed and executed by the University of Maine. Construction of the boat was made possible with a custom large-scale 3D printer, with a volume of 30 x 6.70 x 3 meters and a speed of 227 kilos per hour.

3D printed Bicycles
Pinterest

This award-winning 3D printed mesh bicycle frame was designed by James Novak and made as part of his Ph.D. thesis. The material used is called mammoth resin and is strong enough to hold the weight of most riders. It's very lightweight and easily reproducible. The future likely looks bright for 3D printed bicycles, particularly using metal 3D printing.

So maybe adults don't need a 3D printed book, but certainly, children love the tactile experience of 3D! (We're thinking about pop-up books now.) We foresee a future where children can design their own stories and print them to make them come to life. We can't wait to see what else can be done with a blend of traditional page printing and 3D printing.

3D printed necklace
Pinterest

Can you 3D print metal? You bet! Many at-home jewelry designers are taking advantage of the print-on-demand benefits when it comes to jewelry. A jewelry-maker has two options when it comes to printing jewelry. They can choose to print the cast for the jewelry pieces and fill it with liquid metal. Or they can direct-print the jewelry with the 3D printer.

A special 3D printing is used called direct metal laser sintering (DMLS) or selective laser melting (SLM), and a huge array of metal-types can be printed. You can also print plastic jewelry for certain designs, as well.

3D printed ballet shoes
Pinterest

Dancing en pointe can be brutal on a dancer's feet. If the shoes are not perfectly fit, then injuries can occur throughout the feet and ankles. Designer Hadar Neeman had this in mind when she created a project for her final year in art school aimed at helping with this issue. Her 3D printed ballet shoes are made from scans of a dancer's feet so that the fit can be perfect. Her 3D design is called, fittingly, the P-rouette.

Braille 3d printed

Another beneficial thing a 3D printer can provide is the ability to print various items in braille. Many things like signs, books, and labels can be 3D printed easily to give access in big new ways to those who are blind.

What is braille?

Braille is the 3D writing that consists of a series of patterned, raised bumps, which someone who is blind can follow with their fingers to read.

3D printed Rubik's Cube

And if you think even further outside of the box, think of what other 3D printed items can be made to give access to those who are blind. Besides this 3D printed Rubik's cube, we've seen 3D printed braille maps, board games, and multiplication tools.

inMoov robot

Please don't make every science fiction nightmare come true by 3D printing an entire army of robots like this open-sourced robot from inMoov, a French engineering company. Most of the parts can be entirely printed on an at-home 3D printer with various tutorials available to make it all come together.

Kengoro robot

Another cool 3D printed robot is Kengoro, the sweaty workout robot. This robot was designed to do various workout moves like pushups and situps. It even sweats after the workout gets more intense! This is totally something we would make over at Howchoo!

3D printed headphones

Headphones have been become expensive pieces of electronics to own, particularly the large, over-the-head headphones. For a fraction of the price, some people are printing their own custom headphones like these, which require just a few extra parts like small nuts and bolts to make happen. We can't vouch for the sound quality, but it's a pretty impressive design and 3D print.

But can't you pick one of these up at the store!? Sure. The nice thing about 3D printing a letter board is that you can choose how many and which letters you need to print. (It's also going to be much cheaper.) And if you need a particular letter later on, you simply 3D print that specific letter. No more running out of Es or As!
