Medical imaging allows 3D printers to create patient-matched devices

With imaging data on a person's anatomy, external prostheses and implants, such as cranial plates or hip joints, can be custom-printed to better match a patient's body. Fabrication of porous structures can promote bone growth, leading to longer-lasting implants.

Prosthetics and orthotics have been 3D printed to improve the lives of animals

Shells for hermit crabs, wheelchairs for guinea pigs and dogs, and horseshoes for improved running performance have been created using 3D printers. Other artificial body parts made using this technology include a jaw for a loggerhead turtle, a beak for a toucan, and a tail for an American alligator.

About 2,000 US babies are born annually without some portion of their limbs, potentially leading to a lifetime of pricey prosthetics.

Listen to the evolving economics of prosthetics

Amputees must navigate the challenging medical and economic aspects of limb support and replacement, but advances in technology and research may reduce these costs. A below-knee prosthetic typically costs $15,000 to $20,000—not counting all the rehab costs.

3D printing has made musical instruments more accessible

Massive 3D printers have been used to build homes by stacking layers of 'concrete toothpaste,' a fire-resistant material that effectively insulates against outside noise.

3D printers can create nearly any object that can be digitally designed

Limited only by the size of the printer and the properties of the materials used for printing, fabrications, including household items, toys, props, cases, prototypes, and models, can take anywhere from fractions of an hour to several days to make, depending on design complexity, size, color changes, and printer settings.

Explore a library of data files for 3D printing

Data files are organized by category, including gadgets, learning, and fashion, with most available in .stl format, which is native to computer-aided design software, and presliced. Some files are also available in .3mf, an open-source file format developed as a universal standard for high-fidelity 3D printing.

The first 3D printing patent was filed in 1967

Wyn Swainson, an English literature graduate student, filed a patent in Denmark for a system that scans an object and uses the scanning data to rebuild it using lasers that harden light-sensitive plastic. However, he never developed a working prototype. The idea originated from wanting to produce recreations of sculptures.

Chip-based 3D printers can be pocket-sized and involve no moving parts

Researchers have demonstrated a proof-of-concept version of a chip-based 3D printer that emits visible light onto light-sensitive resin to construct solid shapes. The technology may provide a portable, low-cost solution for future, small-scale fabrication needs.

Watch the engineering challenges overcome in turning a 3D printer into a tattoo machine

The DIY project required reprogramming the printer to operate on a curved, 2D surface rather than making flat layers in 3D, editing replacement firmware to bypass temperature safety checks, and developing a rapid system to stop the tattoo in case of an emergency. The final product printed "LEG" on a volunteer's leg.

Additive manufacturing consists of seven different process categories

Although 3D printing has become synonymous with the term, objects can be fabricated without filaments of hot plastic or light-sensitive powders. For example, during sheet lamination, ultrasonic waves—high-frequency vibrations—can join metal sheets by creating molecular bonds through friction.

In 2015, the FDA approved the first 3D-printed prescription tablet

Spritam, an epilepsy medication, had been too large and difficult to swallow, particularly due to its inability to dissolve easily. The new pill was designed with porous layers to enhance its dissolvability, paving the way for future 3D printing of drugs.

The benefits of 3D printing batteries, from safety to sustainability

Rather than using the liquid electrolyte commonly found in lithium-ion batteries, 3D-printed batteries would use a solid layer, which can be custom-built into different shapes, deliver higher energy density by building thinner layers, and be fabricated with fewer raw materials compared to injection molding.

Objects can be 3D printed with light by projecting 2D computerized tomography (CT) scans onto rotating cylinders of resin, which solidify upon exposure.

Watch the iterative process of successfully printing a slice of vegan cheesecake

3D printing food requires integrating ingredients with a variety of properties, which may not all resist the physical stress of stacking. This means successful 3D printing of food may require rethinking how ingredients are layered and modifying ratios of each, potentially sacrificing taste for structural integrity.

Primary care doctors are converting into membership-based concierge practices

Subscription-based practices sometimes don't accept insurance and they also require annual membership fees which can add up to thousands of dollars per year. In return, patients are promised more personalized care and round-the-clock access to medical providers. As doctors transition to concierge care, this retainer-based medicine model is forcing people to choose between searching for new primary care providers or paying hefty fees.

AI data center growth has created shortages and price hikes in computer parts

Similar demands for the computer memory used in storage drives are expected to keep shortages from easing through 2028.

Fungal diseases cost the US around $19B annually

Estimates derived from health insurance claims, death certificates, and hospitalization data suggest that fungus is a significant medical issue. Each year, fungal diseases kill some 7,300 people—roughly the same number of deaths attributed to motor vehicles striking pedestrians. Around 130,000 people are hospitalized with fungal diseases, and the total national cost from fungal diseases is estimated to be about $19B—a figure that roughly matches Jamaica's entire gross domestic product.
