Filaflex 60A TPU Filament is the softest and most elastic filament in the Filaflex range, achieving an impressive Shore hardness of 60A and a breakthrough 950% elongation at break. Designed for professional-grade applications, Filaflex 60A provides unmatched flexibility and elasticity, making it ideal for advanced 3D printing needs. This latest addition to the 'Filaflex' family shares the elasticity and resilience of other Filaflex filaments (70A, 82A, and 95A), returning to its original shape without deforming when its elastic limit is not exceeded.

Due to its high elasticity, Filaflex 60A is not compatible with all-metal hotends and is not recommended for Bowden-type extrusion systems. However, it offers exceptional bed adhesion without requiring a heated bed or additional adhesives, and is resistant to certain solvents and fuels. Being odorless and safe for skin contact makes it particularly suitable for wearable applications, while proper printer configuration remains essential for optimal results.

Printing Parameters

Complete Technical Printing Guide - FILAFLEX 60A PRO

🌡️ 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!

⚙️ 3. Basic Parameters

Unique Characteristics of Filaflex 60A

Unlike rigid filaments, TPU stretches when extruded, producing thinner lines. The line width will be smaller than the nozzle diameter.To ensure proper bonding between vertical walls and perimeters

Nozzle	Layer Height	Line Width	Volumetric Speed	Temperature
0.4mm	0.2mm	0.34mm	2.0 mm³/s	235°C
0.6mm	0.3mm	0.54mm	4.5 mm³/s	235°C
0.8mm	0.4mm	0.74mm	8.0 mm³/s	235°C
1.0mm	0.5mm	0.94mm	12.5 mm³/s	235°C

↩️ 5. Retraction Settings

🚀 IMPORTANT: Set travel speed to the maximum your machine allows (200-500mm/s). Faster movements reduce filament oozing time, minimizing stringing.

Nozzle	Distance	Speed	Z-Hop
0.4mm	1.5-2.0mm	30mm/s	0.2mm
0.6mm	1.5-2.5mm	30mm/s	0.2mm
0.8mm	2.0-3.5mm	30mm/s	0.2mm
1.0mm	2.0-3.5mm	30mm/s	0.2mm

🌡️ 6. Bed Temperature Settings

Bed Temperature:

Small parts: No heating (room temperature)
Large parts: 40-45°C

❄️ 7. Cooling Settings

Cooling Configuration:

General: 0% (fan off)
KEEP FAN ALWAYS: OFF
Force fan speed for overhangs and bridges: OFF
Layers < 10 seconds: 40% fan
First layer: Always 0%

🔧 8. Troubleshooting Guide

Problem	Solution
Irregular extrusion	1. Dry the filament 2. Check extruder 3. Reduce speed
Poor adhesion	1. Dry the filament 2. Use adhesive 3. Adjust first layer
Stringing	1. Dry the filament 2. Adjust retraction 3. Increase travel speed 4. Check temperature

✨ 9. Best Practices

🌡️ Keep filament dry - store properly and dry before use
⚙️ Preferably use direct drive extruder
🔄 Print multiple small parts simultaneously for better results
🚀 Use maximum travel speed to minimize stringing

⚠️ 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.
