A spool of TPU that has taken on moisture prints with stringing, bubbling and clogging, and a dryer that only warms the outside leaves the core damp. That is the job the best filament dryer for tpu is built for: a box that circulates hot air for even drying and feeds filament straight to the printer.

What the listings tell you, and what they leave out
The five listings state temperature, heater power and spool capacity in different ways, and some figures need a closer look. Only the Sovol SH02 states a safety cutoff, at over 130°C with resume below 90°C. None of the five listings states a warranty term with a concrete unit: the SUNLU listing gives only a bare figure of 1, so its warranty is Not stated here. The Polymaker listing states no temperature range and no heater wattage. Temperature for the Space Pi Plus runs from 45°C to 70°C, for the Sovol SH02 from 40°C to 70°C, and for the SUNLU S2 from 35°C to 70°C, while the Space Pi X4 reaches up to 85°C.

How does a filament dryer work?
A dryer circulates hot air around the spool to remove moisture, with a fan for even heating. The Space Pi Plus and the Sovol SH02 both circulate hot air 360° with a built-in fan.
Why do I need a filament dryer for TPU?
TPU is listed for all five dryers here. The Polymaker listing links moisture to stringing, bubbling, clogging and layer inconsistency.
Do I need a filament dryer for PLA?
PLA is listed for all five dryers here. The SUNLU listing notes that filaments absorb moisture from the air, especially in humid places.
Which dryer has a safety cutoff?
The Sovol SH02 has PTC cutoff over 130°C, resume below 90°C, and a fan-stop alarm. The other dryers state no safety cutoff.
