Space Pi Filament Dryer Plus - Dual Spool 360 Hot-air Dehydrator

Our review of the Space Pi Filament Dryer Plus finds it best suited to hobbyists and makers who run two printers or need to keep two spools ready at once; the defining reason to buy is the dual-roll capacity combined with true PTC hot-air circulation that aims to deliver uniform drying. The unit is practical and easy to use, with a bright 4-inch touch screen and presets for many materials, and it addresses common filament moisture problems without forcing users into complex setups.

Key Features

• Two Rolls Capacity Design: Holds two 1 kg spools and routes filament out through four holes with PTFE pipes so two printers can draw filament while both spools stay dry.
• Double PTC 360 Hot-air Heating: Built-in fan circulates warm air all around the spools for more even drying than surface heating alone, reducing moisture-related print failures.
• Advanced PTC Heating Technology: An 80W PTC heater provides steady, energy-efficient warmth that aims for consistent drying across the storage chamber.
• LCD Touch Screen: A 4-in touch display simplifies monitoring and changing settings so operators can track drying progress without guessing.
• Fast Filament Selection: Twelve preset material profiles cover common and composite filaments and allow temperature adjustment between 45C and 70C for flexible use.
• Power-off Memory: The dryer remembers material and temperature after a power interruption so long drying sessions resume without reconfiguration.

Who It's For

The Space Pi Dryer Plus is aimed at serious hobbyists, small workshop owners, and makers who regularly print with moisture-sensitive materials and want to maintain two spools or feed two machines. It works well for users who value automated presets, a clear touch interface, and the convenience of PTFE feed tubes so prints can continue while drying is in progress.

Those who should look elsewhere include single-spool users on a strict budget who rarely print with hygroscopic filaments, and users who need industrial-scale drying capacity for many spools simultaneously, as this model focuses on two-spool convenience rather than large-scale storage.

Pros & Cons

Pros

• Dual-spool layout and four feed holes enable drying and simultaneous feeding to two printers.
• 80W PTC heater plus 360-degree fan circulation promotes more uniform drying than typical pad heaters.
• Easy operation with a 4-in touch screen and presets for up to 12 filament types.
• Memory function restores settings after power loss for uninterrupted long drying cycles.

Cons

• Does not include filament spools and is intended for 1 kg sizes only, so users must supply compatible spools.
• Some users report mixed overall filament quality or clogging with certain filaments, which is outside the dryer but worth noting when troubleshooting prints.

Specifications

Our Verdict

The Space Pi Filament Dryer Plus is a smart choice for makers who need to keep two spools dry and ready, offering consistent drying thanks to an 80W PTC heater and 360-degree airflow, plus convenient presets and a clear touch interface. For its price and feature set it delivers solid value to dual-printer setups and frequent users of moisture-sensitive filaments, though filament quality issues from third-party spools can still affect results.

Frequently Asked Questions

Can it run two printers at once?
Yes, the unit includes four filament outlets with PTFE tubes so two printers can draw filament while spools remain inside the dryer.

What filament diameters are supported?
The dryer supports both 1.75 mm and 2.85 mm filament diameters as indicated in the product details.

Will it remember settings after a power cut?
Yes, the power-off memory function restores the previous material and temperature settings so drying can resume without reconfiguration.
