3D printing is pretty darn cool. We know it can print makeup, furniture and more, but did you know it can also save lives? Dr. Glenn Green, associate professor of pediatric otolaryngology at the University of Michigan, recently saved a baby鈥檚 life by creating a tracheal splint out of a biopolymer that held open the baby鈥檚 collapsed bronchus so he could breathe. According to the LA Times, the splint is made to grow along with the child, and over time, as the cartilage in the area grows stronger, the splint will dissolve naturally, like biodegradable stitches.

Innovation is certainly inspiring. And you can actually meet Dr. Glenn Green, a true medical hero, at this year鈥檚 Re:Make in SF, where he鈥檒l be talking about 3D printing and medicine. Get your tickets here and read about 10 3D printing medical innovations that are changing the world today.

printed skin

1. Printed skin: Printed skin can be useful for cosmetic purposes, but it can also save lives. An engineering team at the University of Toronto took home the James Dyson Award last year for creating a 3D bioprinter called the PrintAlive that can print large, continuous layers of tissue, down to follicles and sweat glands, onto a hydrogel, to make painful skin grafts a thing of the past. Using the subject鈥檚 own cells, so that the body won鈥檛 reject the sample, the printer may be the answer for burn victims. (via PSFK)

touchable memories

2. Touchable Memories: A 3D printer recreates dimensional versions of a person鈥檚 old photographs and helps blind people see and feel their past again. Touchable Memories is a project started by Spanish creative agency Lola, who wanted to reflect on the human condition using 3D printing technology. According to their site, they are conducting 鈥渁 social experiment where [they] give technology an innovative application鈥 to achieve incredible results鈥 Because wonderful things can be achieved when technology is for all of us.鈥 (via Pirate3D)

cast

3. A Cast that Cuts Healing Time: According to an article by TechCrunch, this cast was created by a Turkish student using 3D printing. The honeycomb shape is one of the sturdiest structures found in nature, and the openings allow for ultrasonic drivers 鈥 which are said to increase the rate of healing 鈥 to be placed directly on the skin. The inventor says that this can heal some breaks up to 80 percent faster. (via TechCrunch)

Prosthetics

4. Prosthetics: Leon McCarthy is one lucky kid. He first made headlines in 2013 when his father printed Leon a 鈥渃yborg鈥 (that鈥檚 what his friends called it!) prosthetic hand for about $10. Leon was born without several fingers, and when his father first heard about 3D-printed prosthetics, he reached out to some of the pioneers of the field and found an incredible at-home solution that would change his son鈥檚 life forever.

pills

5. Printed Pills: Studies have shown that the shape of a pill can actually determine the rate at which medication is released into a patient鈥檚 body. Some may need rapid release, while others may need it to be distributed gradually. There are several shapes that are nearly impossible to make traditionally, and currently, pills only come in a handful of shapes and sizes 鈥 and that鈥檚 where 3D printing comes in. 3D-printed pills can be engineered to take any shape to help better treat illness.

opthalmicdocs

6. Affordable Retinal聽Cameras: Retinal cameras are crucial to preventative eye care and are much needed around the world, but they can cost upwards of $20,000 for one device. Dr. Chiong of OphthalmicDocs and his team found a way to use a 3D-printed apparatus and few lenses to turn any smartphone into an retinal camera for about $33. They also made the design open source and free to download for users around the world. (via 3D Printing Industry)

jaw

7. Jaw Implant: South African doctors managed to successfully use 3D-printed jaw bone implants to reshape the faces of two men. 3D printers are excellent for printing bone implants, like ankle replacements, because the are extremely sturdy (they鈥檙e made with titanium powder!) and are perfectly customized to the patient. (via Health24)

eyes2

8. Prosthetic Eyes: Eye cancer can be extremely fast moving and fatal. Thus, treatment often involves removal of the affected eye. Unfortunately, prosthetics can be extremely expensive, costing up to $15,000. Dr. David T. Tse of the University of Miami is aiming to create a fast and affordable solution with 3D-printed prostheses for those who can鈥檛 afford the steep price tag. (via Brit + Co)

bones

9. Bone Cancer Treatment: In a study published earlier this year, scientists found a way to 3D print custom, biodegradable implants to aid in more effectively treating bone infections and bone cancer. The most exciting part is that this groundbreaking finding was created using very basic desktop 3D printers. (via 3D Printing Industry)

Heart

10. Perfectly Fitted Heart Implants: Dr. Igor Efimov, PhD at the School of Engineering & Applied Science at Washington University in St. Louis and his team found a way to create an elastic silicon membrane that is precisely the shape of a patient鈥檚 heart and can adhere to the surface. The membrane is covered with 3D printed sensors that measure various heart markers and can even deliver a pulse of electricity in cases of irregular heartbeat to save a person鈥檚 life. Science is ah-ma-zing. (via Mashable)
