What is Annealing?

Annealing is a controlled heating and cooling process that helps reduce internal stresses created during printing.

Benefits include:

• Improved dimensional stability

• Reduced internal stress

• Enhanced mechanical performance

• Increased durability

• Better thermal resistance

• Improved long-term reliability

The FilaDryer E2 allows users to perform professional-grade annealing and drying in a single machine.

Professional Annealing Process

The FilaDryer E2 supports proper annealing procedures through precise temperature control.

Typical workflow:

1. Select the proper temperature for the material.
2. Heat the part evenly.
3. Maintain a stable temperature for the required duration.
4. Allow gradual cooling to reduce internal stresses.

This process can significantly improve the performance of engineering-grade printed parts.

Advanced Drying Performance

Moisture is one of the leading causes of print failures in engineering materials.

The FilaDryer E2 helps:

• Eliminate absorbed moisture

• Reduce stringing and oozing

• Improve layer adhesion

• Enhance surface quality

• Minimize print defects

• Restore filament performance

Its fully sealed chamber helps prevent moisture from re-entering during storage and drying.

Intelligent Safety Protection

Designed for professional operation, the FilaDryer E2 incorporates multiple safety systems.

Safety features include:

• Over-temperature protection

• Automatic temperature cutoff

• Audible alarm system

• Fire-resistant materials

• Intelligent monitoring system

• Thermal recovery protection

If temperatures exceed the preset value by 10°C, the system automatically triggers safety alerts and protection measures.

Dual-Layer Thermal Insulation

The FilaDryer E2 features advanced insulation technology to maintain high internal temperatures while protecting users.

Benefits include:

• Internal temperatures exceeding 100°C

• External touch temperatures below 60°C

• Improved energy efficiency

• More stable drying conditions

• Enhanced operator safety

Optimized Durability

SUNLU redesigned key internal components to improve longevity and reliability.

Upgrades include:

• Enhanced motherboard cooling fan

• High-temperature resistant metal bearings
