You’ve probably heard a lot about 3D printing lately. Some people even call it the ‘3D Industrial Revolution.’ But what exactly is 3D printing, and how might it change our future? Let’s break it down. Imagine a regular printer that puts ink on paper. A 3D printer does something similar, but instead of ink, it uses materials like plastic, metal, or even concrete to build three-dimensional objects. It works by stacking layers on top of each other to create complex shapes.
Think of 3D printing like making a loaf of bread, but in reverse. You start with one layer, then add another on top, and keep going until the object is complete. If you’ve lost or broken something you can’t buy anymore, you can create or download a design online and print it yourself. Want a unique gift for someone? You can print it! For example, GE has a Tumblr page called ‘3Dprintmygift.tumblr.com’ where they offer custom 3D-printed gifts for the holiday season.
If your design needs moving parts, the printer can leave gaps or use a special gel that can be washed away later. This allows for highly customized objects made just for you. Imagine furniture, shoes, or appliances designed to fit your lifestyle perfectly. Even prosthetic limbs can be tailored specifically to the person who needs them, rather than being generic products.
Need something small and detailed? Most 3D printers create layers about 100 micrometers thick, but some advanced machines can print layers as thin as 16 micrometers. To give you an idea, a typical bacterial cell is between 1-10 micrometers wide. This precision has led to the creation of 3D-printed medicines, like Ibuprofen, where tiny molecules are arranged perfectly to achieve the desired effect.
Feeling hungry? In the future, you might be able to ask a virtual assistant to 3D print a meal just for you. One of the most exciting possibilities is using living cells, or bio-ink, to print 3D structures. Instead of plastic or metal, imagine printing tissue to replace damaged skin or even entire organs. This could mean no more waiting for organ donors; you could print an organ based on your own genetics. This technology is already being developed!
For example, if someone has a burn or scrape, a scanner can create a personalized map of their skin. The printer then lays down cells layer by layer until the wound is covered. Printing organs is more complex because of their size and the need for blood vessels and other structures. A scanner takes detailed images of a patient’s organ, like a kidney, and the printer reproduces it layer by layer, customized for that person.
While these advancements are still in development, they promise to revolutionize medicine. Although it might be a while before you have a 3D printer at home, when it happens, the world will be a very different place. If you’re eager to see 3D printing in action, GE celebrates 3D Printing Day on December 3rd, or ‘D3 for 3D.’ They offer customized 3D-printed gifts to their fans. You can visit 3dprintmygift.tumblr.com, choose a prototype, and tweet for a chance to receive a printed gift shipped to your home in time for the holidays!

We’ve all heard the buzz surrounding 3D printing—some refer to it as the 3rd or ‘3D Industrial Revolution.’ But what exactly is 3D printing, and how significant will its impact be on our future? The concept is quite simple: much like a traditional printer applies ink to a page, a 3D printer deposits material—whether plastic, metal, or even concrete—to create a three-dimensional object. Instead of printing one layer, as ink does, multiple layers are stacked upon each other to form complex 3D structures.
Think of it like making sliced bread, but in reverse! After placing one layer down, another is built on top, and so on, until the entire loaf is complete. Lost or broken something that you can no longer purchase? No problem—create or download the design online and 3D print it! Have a specific or personalized gift idea for a holiday and can’t find it? Print it! In fact, GE’s Tumblr page ‘3Dprintmygift.tumblr.com’ is doing just that for the holiday season—we’ll include a link in the description.
If your design requires moving parts, the printer can leave gaps in the right places or use a special gel that can be dissolved or rinsed off afterward. Speaking of design, 3D printing allows for incredibly customized objects, made on demand to fit your requirements. This means furniture, shoes, and appliances tailored to your lifestyle, as well as prosthetic limbs that can be completely customized rather than being generic mass-produced products.
Need something small and intricate? Typical 3D printers create layers approximately 100 micrometers thick, but some high-end machines can print as small as 16 micrometers. To put this in perspective, a typical bacterial cell has a width of between 1-10 micrometers. This advancement has opened the door to using molecules for ink, leading to successful 3D-printed pharmaceuticals, such as Ibuprofen. The tiny molecules are organized perfectly to create the desired drug effect.
Hungry? In the future, you might be able to ask a virtual assistant to 3D print a meal tailored to your taste. Perhaps the most significant application is creating 3D structures from living cells, or bio-ink. Instead of using plastic or metal, imagine 3D printing tissue to replace damaged skin or even reproducing entire organs from scratch. Instead of needing an organ donor, you could print one based on your genetics. Remarkably, this technology is already being developed.
For burns or scrapes, a scanner is used on a patient’s wound to create a personalized skin map. The printer then lays down cells one layer at a time until the area is covered. Organs are much more complex due to their size, vascular networks, and interactions with the body. A scanner takes X-ray images of, for example, a patient’s kidney, capturing intricate details. Just like any other object, these organs are reproduced layer by layer, specifically designed for each individual.
Though these advancements are still years away from being fully functional, they will undoubtedly have a significant impact on the medical community. While it may be a while before you have a 3D printer at home, you can be sure that by the time it happens, the world will be a different place. If you can’t wait that long, GE is celebrating 3D Printing with its own holiday on December 3rd—it’s ‘D3 for 3D’! To celebrate, they’re 3D printing and giving away customized gifts for their fans all day. All you need to do is visit 3dprintmygift.tumblr.com to choose one of the prototypes and tweet for a chance to receive one printed and shipped to your home in time for the holidays!
