Recreus PET-G is a high-flow filament engineered for optimal printing performance and exceptional mechanical properties. This versatile material combines excellent printability with superior impact resistance, even at low temperatures, making it ideal for both industrial applications and functional prototypes. Its high-flow characteristics allow for up to 25% faster printing speeds while maintaining precise detail and dimensional accuracy.
Designed for professional use, this PET-G filament offers an excellent balance of flexibility and pressure resistance. Its enhanced flow properties not only improve print quality but also enable significantly faster production times without compromising strength or durability. The material's unique formulation provides outstanding layer adhesion and minimal warping, perfect for creating both technical parts and finished products that require reliable performance.
Note about the "Blue Food Grade" color: This color uses a food-contact-approved pigment that is detectable by optical sensors. The base PET-G material is exactly the same as in all other colors, only the pigment differs, offering improved traceability in industrial applications.

Complete Technical Printing Guide - PETG HIGH FLOW
🌡️ 1. Material Preparation
Filament Drying (CRUCIAL):
- 📏 Temperature: 55°C
- ⏱️ Minimum time: 1 hour
- 💡 Proper drying is essential for optimal printing results
⚡ 2. Understanding Print Speed
Volumetric vs. Linear Speed
- 🌊 Volumetric Speed (mm³/s): Like water through a hose - measures how much plastic flows per second, regardless of nozzle size.
- 📏 Linear Speed (mm/s): Like walking speed - how fast the printer head moves across the print area
- 🔑 Key Formula: Linear Speed = Volumetric Speed / (Line Width × Layer Height)
✨ The Magic: When you set a volumetric speed limit in your slicer, it automatically calculates and adjusts all linear speeds (perimeters, infill, etc.) based on your current nozzle size and layer height. This ensures consistent material flow regardless of your print settings!

✨ 9. Best Practices
- 🌡️ Storage & Material Care:
- Keep PETG in a dry environment (humidity < 50%)
- Use a dry box or sealed container with desiccant
- If needed, dry at 65°C for 4-6 hours
- 🔧 Hardware Recommendations:
- Use hardened steel nozzle for long-term printing
- PEI or glass bed surface recommended
- Enclosure helpful but not mandatory
- ⚙️ Print Setup Tips:
- Use Z-offset slightly higher than PLA (+0.05mm)
- Enable "Avoid crossing perimeters" to reduce stringing
- Consider using "Wipe while retract" option
- Enable "Slow down for small perimeters"
- 🎯 Quality Optimization:
- Print outer walls slower for better quality
- Use minimum layer time of 30 seconds for small parts
- Enable cooling gradually after first layer
- Consider using "Extra Prime Amount" after retraction
⚠️ PLEASE NOTE: These printing parameters are initial recommendations based on our experience. They may need adjustment depending on your specific 3D printer, environmental conditions, and the geometry of the part you are printing. Use these settings as a starting point and fine-tune them according to your specific needs.
