An independent 3D-printing test bench, run from a real print farm.
Standardized test prints and calipers decide the score — never a spec sheet.
No manufacturer pays for placement or a higher score. Rankings are ours alone.
We run long jobs and record real failure rates, clogs and layer shifts over weeks.
Filament Quarry started in 2021 in a cramped two-car garage in Bend, Oregon, where three overheating printers, a mountain of failed prints, and one very patient spouse convinced us that the 3D printing world needed a source of honest, unglamorous product information. We're not a media conglomerate with a content quota to hit. We're a small team of engineers, hobbyists, and one recovering mechanical designer who got tired of reading reviews that read like press releases.
Filament Quarry was founded by Mara Jensen, a former manufacturing quality engineer who spent a decade inspecting injection-molded parts before falling hard for desktop 3D printing. Her first printer, a budget FDM machine bought on a whim, produced exactly one usable part in its first month — everything else was stringing, warping, or a jammed nozzle. Frustrated by review sites that seemed to praise every product equally, she started keeping detailed notes on tolerances, filament moisture behavior, and real-world failure rates. Those notes became spreadsheets. The spreadsheets became a blog. The blog became Filament Quarry.
Today the team has grown to include Devon Ruiz, an electrical engineer who handles firmware and connectivity testing, and Priya Nair, a materials science graduate who oversees our filament testing protocols. Between us, we've owned or tested more than 140 printers and 300 filament spools, and we've thrown away more failed prints than we care to admit.
We focus on two categories: desktop 3D printers (FDM and resin) and filament, because that's where most hobbyists, educators, and small businesses actually spend their money and hit their frustrations. We don't chase every new gadget on the market. Instead, we prioritize products that readers are actually asking about — through comments, emails, and the small but active Filament Quarry community forum.
Every product that appears on Filament Quarry goes through the same core process, regardless of who sent it or whether it was purchased outright:
Filament Quarry earns revenue through affiliate links, meaning we may receive a small commission if you purchase a product through a link on our site, at no additional cost to you. We also occasionally receive review units directly from manufacturers. In every case, the manufacturer has no input into our conclusions, our star ratings, or our final wording, and we disclose sponsored relationships clearly at the top of any affected article. If a product doesn't perform well, we say so — even if that means an awkward email exchange with a brand's marketing team.
Have a printer or filament you think we should test? Found an error in one of our reviews? We want to hear about it. Filament Quarry is built by people who still get genuinely excited about a clean first layer, and we're always looking for ways to make the site more useful for the next person staring at a spool of filament wondering if it's worth the money.
