Oct 25,  · Like the world of Star Wars, which has already been 3D printed, this new age industry will continue to possess a formidable dark side. How we will combat it remains to be seen. May 31,  · It is impossible to predict the dark side of 3D printing. But don’t blame the technology. As with many technologies, 3D printing can be misused, but not because the technology is inherently flawed. People are flawed. Although the size of the problem could be huge, this is only because the technology is so revolutionary and : John Hornick. “From the point of view of 3D printing, complex and difficult products that traditional manufacturing methods cannot carry out can be easily made through 3D printing. On the other hand, mass production and lean manufacturing, where traditional manufacturing have an advantage, are the very weakness of 3D printing technology.

The 3D printer is a double-edged sword. It stands to transform technology and society for the better, but we also can’t ignore the potential negative consequences. But 3D printers are still potentially hazardous, wasteful machines, and their societal, political, economic, and environmental impacts have not yet been studied extensively.

To make sure you aren’t thrown off guard by the conversations to come, we’ve compiled a list of 10 things you need to know about the dangers and potentially negative impacts of 3D printers. When melting plastic with heat or lasers, 3D printers consume about 50 to times more electrical energy than injection molding to make an item of the same weight, according to research by Loughborough University. In , research at MIT’s Environmentally Benign Manufacturing program showed that laser direct metal deposition where metal powder is fused together used hundreds of times the electricity as traditional casting or machining.

Because of this, 3D printers are better for small batch runs. Industrial-sized 3D printers may not be the answer to lessening our use of coal power any time soon. The emissions from desktop 3D printers are similar to burning a cigarette or cooking on a gas or electric stove. The study was the first to measure these airborne particle emissions from desktop 3D printers. While heating the plastic and printing small figures, the machines using PLA filament emitted 20 billion ultrafine particles per minute, and the ABS emitted up to billion particles per minute.

These particles can settle in the lungs or the bloodstream and pose health risk, especially for those with asthma. This potential digital piracy situation is comparable to the way the internet challenged the movie and music industries for copyrights, trademarks, and illegal downloads.

The first successful 3D printed gun is old news, but its ramifications are very important. Engineering firm Solid Concepts has even fired rounds out of the first 3D printed metal gun.

Congress’ Undetectable Firearms Act , which bans guns that can’t be detected by metal detectors or x-ray scanners, was renewed for 10 years. It left a loophole in the law, however: 3D printed guns with a tiny piece of metal aren’t banned by the Act. Legislators are attempting to close that loophole now, after Congress ignored the issue for quite some time, with special requirements for printed guns.

Weapons can be 3D printed. So can safety equipment such as helmets, wheels for bikes, and toys for small children. Of course there is the issue of intellectual property and trademark, but the larger issue involves responsibility. If a person shoots a gun and harms or kills someone, stabs someone with a 3D printed knife, or breaks their neck while riding on a bike with a 3D printed helmet, who is held accountable?

The owner of the printer, the manufacturer of the printer, or the irresponsible person who thought it was a good idea to produce and use an untested product? Assembling chemical compounds on a molecular level using a 3D printer is possible.

A researcher at the University of Glasglow created a prototype of a 3D “Chemputer” that makes drugs and medicine. He wants to revolutionize the pharmaceutical industry by allowing patients to print their own medicine with a chemical blueprint they get from the pharmacy.

Of course, this is a very long way off, but it stands to enable DIY chemists to create anything from cocaine to ricin. A white paper released from the National Defense University highlighted national security risks from 3D printing technology. Since there will be significant legal and economic implications on the business sector and 3D printers offer the ability to produce a wide range of objects that cannot be controlled yet, the paper noted that there are definitely national security risks that need to be analyzed in the near future.

Cornell bioengineers and physicians created an artificial ear that looks and acts like a natural one. Kitchenware is popular to 3D print, but the safety of the materials used is questionable.
