In this review I’m taking a proper hands-on look at the QIDI Plus4, and I’ll be honest—I had reservations going in because I’d seen a lot of mixed feedback in the community. I’m not here to hammer the safety drama in this video though; I’m focusing on how the printer actually performs day to day. Setup was genuinely painless: a couple of transit brackets, unpack the filter, run through calibration on the touchscreen, and I was printing. From there I put it through real-world jobs, not just a quick benchy and done. I go over the key specs and what they mean in practice: 305×305×280 build volume, CoreXY with dual Z, auto bed levelling plus Z-tilt adjustment, 9mm belts, a thicker 6mm bed, and a high-temp hardened nozzle (up to 370°C) with a chamber that can hit around 65°C. I also show a bunch of prints—PLA, PETG, and even PA-CF—plus functional bits like a rear purge bin. My results were genuinely solid: first layers were spot on with no Z tweaks, pause-and-resume stitched cleanly after a filament runout, and the machine just felt premium and consistent. I do call out a couple of annoyances: the screen can’t tilt, the UI felt sluggish/laggy at times, and the camera looked awful until I manually focused it (then it was properly 1080p). Overall though, for build quality, speed, materials capability, and print results, I think the Plus4 is a brilliant bit of kit—especially if you want to step into bigger, hotter, more capable printing.
