A brief history of 3D printing

A brief history of 3D printing

On that evening, more than three decades ago, when he invented 3D printing, Chuck Hull called his wife.

She was already in her pyjamas, but he insisted that she drive to his lab to see the small, black plastic cup that he had just produced after 45 minutes of printing.

It was March 19, 1983. Hull was then an engineer working at a U.S. firm that coated furniture with a hard plastic veneer. As part of his work, he used photopolymers — acrylic-based liquids — that would solidify under ultraviolet light. Hull thought the same sort of process might be used to build a three-dimensional object from many thin layers of acrylic, hardened one after another, with targeted UV light from a laser beam.

Hull pursued his research on nights and weekends until finally sharing his eureka moment with his wife, Anntionette.

“I did it,” he told her simply.

Chuck Hull, inventor of the 3D printer

Hull took out a series of patents on his invention and went on to co-found a company, 3D Systems, that remains a leader in the field. Last year, the 75-year-old was inducted into the National Inventors Hall of Fame.

Hull’s invention launched a wave of innovation. Design engineers embraced 3D printers as the answer to their prayers: Instead of waiting weeks or months to have new parts produced, they could design them on computers and print prototypes the same day.

3D printers have since evolved and can now use all kinds of materials, including metals, ceramics, sugar, rubbers, plastics, chemicals, wax and living cells. It means designers can progress rapidly from concept to final product.

Advances in the printers’ speed, accuracy and versatility have made them attractive to researchers, profit-making firms and even do-it-yourselfers.

The cost of the machines has also dropped dramatically, which means it’s easy for home inventors to enter the field. Home Depot sells a desktop version for $1,699 while Amazon.com markets the DaVinci Junior 3D printer for $339.

The machines have been used to print shoes, jewellery, pizza, cakes, car parts, invisible braces, firearms, architectural models and fetal baby models (based on ultrasound images).

The wave of innovation triggered by the 3D printer is only now beginning to crest in the field of medicine. Researchers are racing to engineer implantable livers, kidneys and other body parts with the help of 3D printers.

In Canada, scientists are using 3D bioprinters as they work toward creating new limb joints made from a patient’s own tissue, and implantable skin for burn victims.

Ford Launches Online 3D Printed Model Car Shop – Print Your Favorite Ford Car or Truck Today

The automobile industry has long been known to be one of the most aggressive when it comes to using 3D printing technology. In fact, car manufacturers were some of the very first businesses to utilize 3D printing in order to rapidly prototype various automobile parts and designs. This has been going on literally for decades, but in recent times, we have begun to see car manufacturers take the idea of 3D printing a few step further. There have been car parts which have been completely 3D printed, entire cars — in the case of Local Motors — that have been printed in plastic, and various other innovations going on within the automobile industry. 3D printing certainly has its place not only in current car manufacturing but in the future as well.

Today, Ford Motor Company has informed 3DPrint.com that they are taking things to a whole new level when it comes to 3D printing. No, they aren’t 3D printing an entire car, nor are they allowing people to 3D print replacement parts, but what they are doing will certainly appeal to both fans of the company as well as car enthusiasts and collectors in general.

“Just in time for Father’s Day! Today Ford announced that it is the first automaker to open a one-stop 3D digital shop – the Ford 3D Store,” Ford Motor Company tells 3DPrint.com. “Now, with the help of Turbosquid, Ford fans can use advanced technology to make their own models of Ford vehicles or opt to purchase a 3D digital file from a growing library of more than 1,000 Ford vehicle images.”

Available to order models include the new Ford GT, F-150 Raptor, Shelby GT350R, Focus ST, and Fiesta ST with plenty more models coming in the very near future. These models are printed at 1:32 scale in plastic and are priced at $39.00. However, if you own a 3D printer yourself, or have access to one, you can purchase the 3D design files for a measly $4.99. This allows you to scale the car to whatever size you wish and print it out yourself.

“3D printing at home is a growing trend, and it makes sense for us to offer our customers a chance to make their own 3D Ford models,” explained Mark Bentley, licensing manager of Ford Global Brand Licensing. “At Ford, we’re using 3D printing every day to rapidly prototype parts, and now we want to share that fun with our fans.”

So what exactly spurred Ford into making these incredibly detailed and accurate replicas available to 3D print? Seemingly it is the fact that researchers are predicting that sales of desktop 3D printers will exceed 1 million units within the next 3 years, over twenty times the number sold last year.

The Ford 3D Store website has been built by Turbosquid, a company that specializes in selling 3D models and stock images. They have extensive experience when it comes to selling similar models which are capable of being 3D printed, so they have a clear understanding of IP laws and various methods of securing files. When users purchase a 3D model, they must agree not to distribute it elsewhere.  This has the potential of bringing up an issue which certainly has been looming for the 3D printing space for the past few years. It should be interesting to see how companies like Ford and Turbosquid ultimately deal with such IP conflicts that may arise if people begin to freely share these files, without providing Ford with any royalties.

“TurboSquid already allows customers to purchase more than 1,000 unique, licensed digital images of Ford products ranging from the Model T to the all-new Ford GT,” said Bentley. “We’re at the forefront of licensing 3D automotive images, and it made sense that TurboSquid help us complete that connection to the consumer.”

Without a doubt, this is huge news for the 3D printing space. The idea that individuals can now purchase 3D printed models of licensed replicas, or the design files for these vehicles and then print them out themselves, is something that no other car manufacturer has yet to do. It should be interesting to see how well this business model works, and we will certainly be keeping an eye out for future models which are released to the Ford 3D Store.

What do you think about this announcement? Will you be downloading and printing your own Ford vehicles anytime soon? Should other car manufacturers contemplate doing the same thing as Ford has? Discuss in the Ford 3D Store forum thread on 3DPB.com.
