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.

As of 2025, the Factory of the Future 1.0 is the world's largest 3D printer

Housed at the University of Maine, the machine incorporates AI and can utilize bio-based materials to construct homes exceeding 3,000 square feet in size. Homes made from these materials are fully recyclable, as their components can be deconstructed, ground up, and reused as raw materials for printing.

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.

View a timeline of 3D printing technology through 2019

The first working 3D printing device was invented in 1983 and utilized stereolithography, a process in which a laser triggers a chemical reaction that hardens liquid resin. Powder-based laser sintering technology was patented in 1987, with metal-based powders first being used for 3D printing in 1997.

Software subscriptions, licenses, and climate control systems add to 3D printing costs

Although the sharing of designs and reduced manual labor suggested the fabrication of prosthetics would be facilitated by 3D printing, particularly in developing regions, software and hardware requirements have posed hurdles to achieving this goal. While some insurance companies have refused to cover 3D-printed limbs, they are covered by Medicare.

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.

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.

View a gallery of 3D printed clothing

Many 3D printed garments represent wearable art where technology meets couture.

The most common type of 3D printer fabricates objects using plastic

At the consumer level, the most common printing method is fused deposition modeling, which builds objects by melting an extruding thermoplastic filament that is deposited in layers. For industrial applications, selective laser sintering, which uses a laser to fuse particles of polymer powder (e.g., nylon), is preferred.

3D printing has made musical instruments more accessible

Violins fabricated from durable plastic, rather than being built from wood, can cost hundreds of dollars less, allowing children to try them out without financial pressure.

Most custom earmolds for in-ear hearing aids are made using 3D printing

The technology has also been utilized for behind-the-ear and receiver-in-canal hearing aids, allowing for the creation of structures tailored to the patient's anatomy for enhanced effectiveness. 3D printing has also been used to print retinal eye cells and custom eyeglass frames.

Microgravity environments improve the success of 3D bioprinting

Gravity can cause gaps, such as those in the chambers of a 3D-printed heart, to collapse before stem cells, hydrogels, and biochemicals bind together during the bioprinting process. Rather than Earth's surface, some bioprinting is done on the International Space Station, where defective organs are also printed to test treatment methods.

Watch Apple Watch cases be 3D printed from titanium powder

Apple Watch Ultra 3 cases are 3D printed entirely from recycled, aerospace-grade titanium powder using lasers to fuse particles.

Multi-material 3D printing produces filament waste if only one nozzle is used

When swapping between colors or materials in a fused deposition modeling system, a considerable amount of filament is purged from the nozzle before introducing a new filament. Filament extruders can create new filament from purged elements, but the device combines colors and produces filaments of inconsistent diameter.
