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.

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.

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.

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.

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.

Components of the 'ghost gun' allegedly used by Luigi Mangione were 3D printed

Although some "ghost guns" are firearms whose serial numbers have been removed, many others are built from pieces that can be printed using readily available online data files. Federal laws and some states do not prohibit the construction of these DIY firearms for personal use.

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

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. Over 400 metric tons of raw titanium were saved in 2025, with two watches fabricated from the same amount of raw material that would have previously been used to make one.

The Internet Archive is a nonprofit digital library of the Web

Founded in 1996, the Archive promotes open access and the digital preservation of online information and, as of 2026, contains more than 200 petabytes of content, including over one trillion web pages, 56 million books and texts, 13 million audio recordings, 1.3 million software programs, and other digital content.

During Mark Zuckerberg's sophomore year at Harvard, he built a website that allowed users to rank and rate people's pictures from the school's online "facebooks" called Facemash.com, which quickly went viral. He was placed on academic probation for violating the school's rules around data, privacy, and computer usage. Zuckerberg says the website was a prank and he never intended for so many people to see it. FaceMash is credited with being the predecessor to Facebook.
