Cold chamber, warped first layers, a print that curled off the bed before layer five. You've been blaming the filament. It's the room temperature. The Elegoo Mini Heater uses PTC heating to push your print chamber up to 25°C fast, so PLA and PETG lay down flat and consistent. A 10,000 RPM fan moves that heat evenly across the build area — no hot spots, no cold corners. Real-time temperature feedback keeps you in the loop without guessing. Built-in air filtration means the fumes don't just sit there. You get the heater, filters, mounting hardware, an IEC mains cable, and a 24VDC 5A barrel-plug power supply. Plug it in, mount it, print
