3D printing crossed from hobbyist-novelty to genuine practical tool around 2023. By 2026 the printers themselves work — Bambu Lab and Prusa both ship machines that print reliably without becoming the hobby — and the bottleneck has shifted to the software, the materials, and knowing what's worth printing. This page is for someone who wants to use 3D printing as a tool (and occasionally as a creative practice) without joining the 'every weekend is calibration' culture, organized by what each part of the practice requires: the printers worth buying in 2026, the software ecosystem, the materials and their actual tradeoffs, and the communities and references for finding what to print and how. One deliberate omission: SLA/resin printing is not covered — that's a more specialized practice with different ergonomics and safety considerations.
