Choose around the job.
Two rolls need drying together
The Plus is the capacity to compare first. Measure the rolls you actually use and check clearance for loading and routing filament.
Three or four rolls regularly need drying
Compare the four-spool SUNLU S4. More capacity is useful only if you will use it; neither name establishes compatibility with an automatic material feeder.
Your material needs a different process
Follow the filament maker’s drying conditions. Choose another drying method if the required temperature or spool fit falls outside the unit’s specification.
