How It Works
The unit uses two independently controllable chambers, each with separate temperature and humidity settings. The built-in moisture sensor starts the drying process when humidity rises, and the 4-inch touch display provides presets for PLA, ABS and PETG.
When the dryer is not being used for active drying, the chambers can be used as storage boxes. The listing also states that the 4 filament outputs allow flexible installation.
What To Know Before You Buy
Check that your filament is 1.75 mm and that the materials you use match the listed PLA, ABS, TPU or PETG support. If you want to print straight from the box, confirm that your setup suits the stated AMS Lite compatibility and PTFE tube arrangement. Review the 4-spool capacity and the two-chamber layout to make sure it suits your workspace and filament workflow.
