3D printing for dental use allows for cheaper and more personalized fittings that take very little time to print and significantly increase patient satisfaction.

Implants and Crowns

Dental implants are made using 3D scanners to create molds accurate to a patient’s mouth. Using 3D printing with castable resins, they can then be made on-site and often on the same day.

Dentures

Using similar techniques, 3D printed dentures can be made to suit an individual patient’s mouth instead of a slightly modified off-the-shelf model. Using specific dental 3D scanners, anyone can get dentures that are a perfect fit without any additional hassle caused by more traditional manufacturing methods.

Retainers and Aligners

Dental 3D printing can be cosmetic too. Just like with dental implants, retainers and aligners can be 3D printed in a matter of hours and be specific to an individual. Using 3D printing in the manufacturing process cuts not only cost and wait times, but also improves comfort and reliability.

Prosthetics

  • Learn More: 3D Printed Prosthetics

3D printed prosthetics are far cheaper and faster to make than their conventionally manufactured counterparts. And with 1 in 1,900 newborns in the US being born with a limb difference and around 2.1 million Americans living with limb loss today, the demand is high.

Limbitless Solutions

Limbetless Solutions specializes in 3D printed prosthetics for children, taking advantage of additive manufacturing techniques to save on money as well as make customizable prosthetic limbs to match the child’s preferences. The files used to model these prints are saved so bigger models can be made as the child grows.

LifeNabled

3d printed prosthetics

LifeNabled makes good use of 3D printing to make effective and affordable prosthetics for the underprivileged people of the Petén. After seeing the dismal conditions in which the free prosthetics clinic in Guatemala was run, founder Brent Wright researched 3D printed prosthetics to create LifeNabled, providing much-needed prostheses to those who otherwise could not afford or access them.

E-Nable

E-Nable, or Enabling The Future, began life as a cosplay piece that caught the attention of an amputee, leading to one of the biggest collaborative 3D printed prosthetics organizations in the world. Designs like the Cyborg Beast and models for functional hand, wrist, and elbow prosthetics are already helping to change the world.

Bioprinting

  • Learn More: 3D Printed Organs

Approximately one-third of organ transplants are lost to rejection, and there are no treatments that guarantee success. But with 3D printed organs, the patient’s own cells are used so there is no chance of the body rejecting it.

With the addition of metal 3D printing to make implantable joints, bone segments, and even entire bone structures unique to a patient’s specifications, bioprinting shows significant promise in the medical field.

Skin

Cited as an ‘easy band-aid’ in 2019, 3D printed skin has come a long way in recent years. Printing functioning follicles for hair growth and working sweat glands and other properties are being achieved and perfected year by year.

Hearts

While 3D printed hearts are still largely theoretical, an exciting breakthrough by the University of Erlangen-Nuremberg in June 2023 showed a lot of promise. The study used human cells and bioprinting to create miniature ventricles that could actually keep rhythm like a human heart.

Kidneys

Kidneys are amongst the most in-demand organs for transplant, and the supply is dwindling to the point where many people are waiting upwards of two and a half years for a donor.

3D printing functional kidneys is no longer the pipe dream it once was, as studies in late 2022 found significant data that cell-based bioprinted kidneys could be the key to complication-free transplants in the near future. 

Livers

Despite their unique regenerative abilities, livers are also amongst the most in-demand organs for transplant. While it is unfortunate that, according to this 2022 study, transplantable 3D printed livers are still a long way off, the upside is that 3D printed livers are already being used to research the causes, effects, and treatments of liver-specific diseases.

Shelters

In the midst of a worldwide housing shortage, the use of concrete 3D printers offers super fast, cheap, and automated house building. They work based on digital CAD files, reducing the need for time-eating design processes or numerous skilled builders.

New Story

Non-profit building company New Story uses 3D printing to construct cheap, sustainable homes in a total of 24 hours over a period of several days using only local and zero-waste materials. They’re a donation-based company, using every penny towards their relatively inexpensive production (~$10,000 per house) in the hopes of putting a sizable dent in homelessness statistics, aiming to have homed 1 million people by 2030.

ICON

3D printed construction companies don’t come much bigger than ICON, a Texas-based construction company using 3D printing to create beautiful, sustainable living spaces like the suburban fantasy Genesis Collection to the affordable Initiative 99. Applications for the latter, which costs less than $100,000 to build, are open now.

Project Olympus

NASA-funded Project Olympus is another ICON project designed to 3D print shelters and even roads for long-term habitation on the moon. Started in 2020 with a budget of $57.2 million, and continues to this day. The plan not only involves building homes for explorers as part of a larger lunar base, but also launchpads and other infrastructure using actual lunar and martian resources.

Vehicles

Additive manufacturing has been used in the automotive industry for quite some time, overtaking traditional manufacturing processes by allowing for low-cost rapid prototyping and 3D printing lighter parts for more efficient vehicles.

High-end fashion designers like Danit Peleg and Julia Daviy have taken to 3D printing to create custom, intricate designs for their lines. They achieve this largely by using flexible filaments that can complement the body’s contours like TPU.

Costumes

2018’s Black Panther featured Wakanda, a utopia that combined traditional African culture with modern-day settings, and they needed the clothing to match. To blend these two looks seamlessly (pun intended), designer Julia Koerner used 3D printing to create many of the more intricate costumes seen in the movie.

Kinematics Dress

3D Printed Dress

The Kinematics Dress was designed to overcome the main challenge of 3D printing clothing, the brittle nature of most filaments. They achieved this by 3D printing a dress made of small interlocking parts that act like small hinges, allowing them to move with the body instead of against it.

Thanks to the capabilities of even low-cost resin 3D printers, anyone can make their own 3D printed jewelry to some extent. Even consumer printers from Elegoo and Anycubic are good enough to create resin molds that can be used for “lost wax casting” to create gold and diamond jewelry. These designs can be saved as custom STL files to be replicated, shared, or sold.

Rapid Prototyping

  • Learn More: What is Rapid Prototyping?

Before 3D printers, prototyping was a lengthy process as testing new prototypes could take days or weeks. With 3D printing, new prototypes could be printed in hours, tested for effectiveness, and then changed and improved in CAD software based on the results.

Heavily used across the car and automotive, engineering, aerospace, and architecture industries, 3D printing for prototyping has significantly sped up development in a lot of important fields.

Food

  • Learn More: 3D Printed Food

Standard FDM 3D printers extrude melted plastics, layer by layer, to create a final 3D object. Therefore, by replacing the plastic extruder with a special paste extruder, food 3D printers can create 3D printed meals in a variety of delicious edible materials, and in custom designs.

Food Ink.

Hipster restaurant pop-ups have appeared across big cities, offering pretty plates of 3D printed food at luxury prices. Food Ink. is one of the more impressive examples, as their flagship restaurant is entirely 3D printed from the furniture to the food.
