When 3D printing was first introduced over 30 years ago, few could have imagined how widespread its applications would become today. Among the many uses of 3D printing technology, I've selected what I consider to be the most fascinating seven applications. Let’s take a closer look at them.
First, 3D printed cars.
Back in 2013, Volkswagen announced a project involving 3D printed vehicles that could reach speeds of up to 100 miles per hour. More recently, a local automaker tested a 3D printed car called Stradi. In fact, the first 3D printed car ready for road use is set to enter mass production soon and will be sold through the company.
Second, 3D printed houses.
The size of a 3D printed object depends on the printer itself. The UAE's National Innovation Commission recently announced plans to build the first 3D printed office building, complete with 3D printed walls and furniture. The 2,000-square-foot structure will be built using a 20-foot-tall 3D printer. Engineers estimate it can be completed in just a few weeks, reducing labor costs by 50% to 80%, and construction waste by 30% to 60%.
Third, 3D printed drugs.
Although 3D printed medications aren’t entirely new, the U.S. FDA recently approved the first 3D printed drug. This approval could benefit up to 3 million adults and children suffering from epilepsy. It may also pave the way for creating more personalized, easier-to-use, and cost-effective medicines. According to The Washington Post, in the future, your doctor might give you an algorithm instead of a prescription, allowing you to print your medication at home—your own personalized 3D printed medicine.
Fourth, 3D printed tools and parts for space stations.
When NASA sent the first 3D printer to the International Space Station, the goal was to use it to create parts for repairs. By transferring 3D printed files between modules, astronauts were able to build tools and even print parts of the printer itself. They successfully created 14 projects without major issues.
Fifth, bioprinting.
If you lose an ear, you might think you’ve stepped into a Van Gogh painting—but now, that’s no longer something to fear. In a recent science article titled “Science Can 3D Print 3 Organs for Your 3D Printing,†the ear was listed as the first item. With a 3D scan of your ears, bioengineers can create molds using CAD software, then print them using bio-gel materials and reattach them after incubation in a lab.
Sixth, 3D printed food.
NASA has even considered whether astronauts could one day enjoy a pizza made with a 3D printer. Typical 3D printing materials include dough, cheese, and sauce, making it possible to create customized meals in space.
Seventh, nano 3D printing materials.
While large 3D printers are used for buildings, nano-scale 3D printing materials have a broader range of applications. They are used in electronics, currency (especially for security features), passports, and even artwork. These tiny but powerful technologies are shaping the future in ways we’re only beginning to understand.
