Comgrow Filament Dryer Box SH02
The Comgrow SH02 model provides dual-spool capacity with two filament holes for PTFE piping, accommodating different extruder positions. It features a 150W PTC heater designed to heat quickly and efficiently, achieving 50°C in about seven minutes and 70°C in roughly 25 minutes. A built-in fan circulates hot air 360° to ensure uniform drying, which helps reduce moisture-related print issues across a range of filaments. The device supports nine filament types and offers a single-key temperature selection for convenient operation. Drying times can extend up to 98 hours for extended moisture control.
Creality 2025 New Filament Dryer Box 2.0
Creality’s 2025 New Filament Dryer Box 2.0 emphasizes rapid heating with a built-in 360° fan for even heat distribution. Users can expect the chamber to reach around 65°C within 15 minutes. The box includes thermal insulation on inner walls to minimize heat loss and protect filaments during drying. A real-time humidity monitor and a countdown display keep users informed about drying progress. It ships ready to use without assembly and encourages storing dried filament in a vacuum bag post-drying to retain dryness and readiness for printing.
Creality Filament Dryer Box Pro
Creality’s Pro version adds enhanced sealing and a 360° hot-air flow system to ensure uniform drying. It supports multiple filament types and diameters, notably 1.75mm and 2.85mm. The unit provides flexible drying time and temperature settings to accommodate differences in filament hygroscopicity and ambient conditions. It is designed to reduce moisture- and heat-related print issues, including poor adhesion and clogging, while offering a straightforward user experience with adjustable parameters for repeatable results.
Creality Space Pi Filament Dryer Plus
The Space Pi Dryer Plus is designed for dual-spool operation, enabling two 1kg spools to dry simultaneously. It uses a 360° heating approach with a dedicated PTC heater and a four-inch touchscreen for easy operation. The unit includes presets for common filament families, making it simple to choose a material type and start drying. This model is positioned as an all-in-one solution for organized filaments and reliable drying, suitable for busy workshops with limited space and multiple printers.
Comgrow 3D Printer Filament Dryer Box
Comgrow’s standalone dryer box offers a large internal capacity capable of storing two spools of 1kg each. It emphasizes keeping filaments dry during printing and provides a user-facing control panel that guides temperature and duration settings. The design aims to prevent entanglement, clogging, and poor adhesion associated with damp filaments, supporting 1.75mm and 2.85mm diameters. While it requires careful operation to avoid automatic shutdown issues, supportive customer service notes help address setup questions and ensure optimal performance.
Official Creality Filament Dryer Space Pi
The official Creality Space Pi model highlights a dual 110W PTC heater arrangement and a 360° hot-air system designed for uniform drying. It offers a four-button LCD touch interface for temperature and time control, with a wide range of preset materials. The device supports various materials and allows switching between Celsius and Fahrenheit. It’s positioned as a robust, user-friendly option for double-spool setups and ongoing filament readiness in professional or educational environments.
Creality Space Pi Filament Dryer (2025)
The 2025 Creality Space Pi model emphasizes upgraded PTC heating with a 360° hot-air system, aiming for uniform drying. The 3.7-inch LCD touch screen facilitates easy monitoring of temperature and time, and it supports multiple filament types. The system is designed to balance speed with consistent drying, offering flexible settings for a variety of printing scenarios, including nylon and carbon-fiber-infused filaments.
Buying Guide: Key Considerations for Healed Filament Dry Boxes
- Filament capacity: Determine whether you primarily dry one or two spools at once and whether you need compatibility with 1.75mm, 2.85mm, or other diameters.
- Heating method and speed: Look for a heater type that provides uniform 360° airflow and a reasonable time to reach target temperatures (e.g., 50–70°C). A faster heat-up typically reduces total drying time.
- Controls and presets: One-key or preset-based operation can simplify daily use. Consider if you need presets for specific materials like PLA, PETG, ABS, nylon, or more specialized filaments.
- Sealing and moisture protection: A robust seal helps keep filaments dry when the unit is not powered. This is important for long-term storage between printing sessions.
- Display and monitoring: An LCD or touchscreen display that shows temperature, time, and humidity helps you track drying progress and adjust settings as needed.
- Space and workflow integration: Dual-spool designs save space and support two printers, while compact single-spool models fit tighter workspaces. Consider whether you need a freestanding box or a compact, integrated unit.
- Material compatibility and safety: Ensure the unit supports the filament types you use (PLA, PETG, ABS, ASA, PA, PC, etc.) and adheres to safety standards for heating devices in home or lab environments.
- Maintenance and support: Look for clear setup instructions, after-sales support, and accessible firmware or part replacements in case of wear or issues.
Choosing the right heated filament dry box involves balancing capacity, speed, and simplicity of operation with the variety of filaments you use. For multi-printer setups, a dual-spool model with a reliable 360° heating cycle offers the most efficiency. For single-printer environments, a compact unit with strong sealing and easy presets can provide consistent results without occupying excess space.
