Remember the Jetsons  – that sci-fi cartoon from the early 60’s?  Perhaps the cartoon was best known for flying cars and dinner served with the push of a button.

Today with 3-D printing we’re getting even closer to that reality. With this new technology we are reshaping the way we innovate and build products that even George Jetson would be proud of.

We’ve all seen those early examples of printed objects which ended up looking like tangled spaghetti more than anything else. While it’s true that 3D printing may be merely a fad for the hobbyist,  it has also been used in defense, medicine and yes even for dinner.

So lets jump right in to the evolution of 3D printing. Explore our examples of 3d printing below – many interesting, lots useful, and some even entertaining.


Since 2008 when a the self replicating printer named RepRap was invented, 3-D printing has been on the “up swing” ever since.

Early Examples of 3D Printing

Early examples of 3D Printing

1. RepRap’s Self-Replicating Printer: In 2008 RepRap created a printer, named Darwin, that could print its own parts as well as many other 3D objects. This project opened up 3D printing to many new people and began an open-source movement.

2. Prosthetic Limbs: In 2008, the very first person walked on a 3D printed prosthetic leg. This innovation opened the way for Bespoke Innovations to develop 3D printed coverings for prosthetic legs, customized to match each person’s remaining leg and style.

3. MakerBot’s Cupcake CNC: MakerBot Industry is a New York based company that produces 3D printers for consumers. In March 2009 they began selling their first device, the Cupcake CNC, a highly customizable do it yourself printer that could 3D print objects up to 100 by 100 by 130 mm large.

4. Organovo’s Blood Vessel: In 2009, Organovo produced the first 3D printed blood vessel, one of many medical uses of 3D printing. This example also can be referred to what is called Bio Printing.

5. Organovo’s Human Vein: Continuing to expand the uses of 3D printing for medical purposes, in 2010 Organovo printed a human vein that uses organ cells, built around a printed scaffolding of “bio ink.”

6. Kor Ecologic’s Car: Urbee became the world’s first 3D printed car in 2011, and Kor Ecologic will soon come out with the Urbee 2. Urbee is a 3-whelled hybrid car, with both the exterior and interior made from 3D printed parts. It weighs only 1200 pounds, meaning that it uses fuel very efficiently.

7. Wake Forest’s Kidney Prototype: Scientists at the Wake Forest Institute for Regenerative Medicine, led by director Anthony Atala, created a 3D mold of a human kidney using biocompatible materials combined with human cells. The printed kidney lacked the inner structures of a real human kidney but opened the way for further work that in the future might enable the transplantation of functioning 3D printed organs.

8. University of Southampton’s Robotic Aircraft: Engineers at the university built a robotic, unmanned aircraft in 7 days. They built the plane with elliptical wings, a feature that is expensive to manufacture using traditional methods, for a total budget of only 8,000 US dollars.

 9. imaterialise’s Jewelry: For the first time, a company began using sterling silver and gold as materials for 3D printed goods. Their products included necklaces, rings, and other jewelry. This innovation opened the doors for other jewelry to be manufactured that is inexpensive and highly customized.

10. Instructables First Vinyl Record: A 3-D Printed record of Kurt Cobain Nirvana is printed by Amanda from Instructables – the grooves are 10x wider so one record is about 6 minutes of playtime. The video below demonstrates this record and others which are printed using high resolution file:

11. 3D Systems’ Drum Kit: 3D Systems, a US based company, used a strong form of nylon to print a 5-piece drum kit. The drums feature intricate cut-out designs and have been played as part of a whole 3D printed band.

protocol training shoes34. Protocell’s Running Shoes: A London designer named Shamees Aden created a prototype for an exciting new kind of running shoes. They are 3D printed to precisely fit the user’s foot and can even by dyed any color for the utmost in customization. Even more excitingly, the shoes, called Protocells Trainers, are made of protocells, a kind of molecule that reacts instantly to light, movement, and pressure. This means that as a user runs, the material can instantaneously react to provide extra to support to areas of high impact. After a run, the shoes can be placed into a jar of protocell liquid, which can repair any tears in the material overnight.

flying drone35. Plasticity Production’s Flying Drone: Louis DeRosa of Plasticity Productions used a 3Doodler to create a working hexacopter framed drone.

Some additional notes on 3D Printing

Well we hope you have enjoyed our examples of 3D printing.

As 3D printing becomes ever more popular, we think it will be interesting to see how regulations of intellectual property surrounding this technology might change.

Among the many controversies surrounding 3D printing, one of the most famous is gun control. In 2012, a group in the U.S. called Defense Distributed created a 3D printed plastic gun and published the design online, allowing anyone with a 3D printer to create their own gun.

Currently though, in the U.S. it is legal for individuals to produce their own firearms for personal use (excluding assault weapons and Title II weapons such as machine guns). In most of Europe, it is illegal to produce a gun using 3D printing.

3D printing also poses some complicated challenges to intellectual property and copyright. It is possible, for instance, to create a design based on a physical product that already exists, 3D print it, and sell it yourself.

Many online 3D printing communities, such as Thingiverse and Shapeways, include designs for figurines of movie and TV show characters, for example. Usually, these designs stay up unless a copyright holder asks for them to be removed.

Despite these complications, it seems certain that 3D printing is going to continue growing. Companies such as Organovo, Stratasys, MakerBot, and Shapeways are continuing to find new applications for 3D printing and bringing it to an ever-growing audience.

3D printing is also gathering investments and partnerships from many large names, including NASA, Hewlett-Packard, and Amazon. These companies and individuals everywhere are recognizing the potential that 3D printing has.

Perhaps what is most exciting about 3D printing, however, are the possibilities that we can’t yet imagine. The technology of 3D printing has already come so far. It has helped many people and industries and become increasingly accessible.

Furthermore, it is characterized by enthusiastic and creative people constantly creating new uses for it. It seems certain that 3D printing will continue to surprise us in the future.
