Printing Parameters

Complete Technical Printing Guide - FILAFLEX 95A

🌡️ 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 95A

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	0.38mm	4.5 mm³/s	245°C
0.6mm	0.3mm	0.58mm	10.1 mm³/s	245°C
0.8mm	0.4mm	0.78mm	18.0 mm³/s	248°C
1.0mm	0.5mm	0.98mm	28.1 mm³/s	250°C

🚀 4. Speed Settings

0.4mm Nozzle (Volumetric Speed: 4.5 mm³/s)

Line Type	Percentage	Speed
External Perimeter	50%	29.61 mm/s
Internal Perimeters	75%	44.41 mm/s
Infill	100%	59.21 mm/s
Top/Bottom	60%	35.53 mm/s
First Layer	30%	17.76 mm/s

0.6mm Nozzle (Volumetric Speed: 10.1 mm³/s)

Line Type	Percentage	Speed
External Perimeter	50%	29.01 mm/s
Internal Perimeters	75%	43.52 mm/s
Infill	100%	58.02 mm/s
Top/Bottom	60%	34.81 mm/s
First Layer	30%	17.41 mm/s

0.8mm Nozzle (Volumetric Speed: 18.0 mm³/s)

Line Type	Percentage	Speed
External Perimeter	50%	28.85 mm/s
Internal Perimeters	75%	43.27 mm/s
Infill	100%	57.69 mm/s
Top/Bottom	60%	34.62 mm/s

1.0mm Nozzle (Volumetric Speed: 28.1 mm³/s)

Line Type	Percentage	Speed
External Perimeter	50%	28.67 mm/s
Internal Perimeters	75%	43.01 mm/s
Infill	100%	57.35 mm/s
Top/Bottom	60%	34.41 mm/s
First Layer	30%	17.20 mm/s

↩️ 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	1.8-2.5mm	40mm/s	0.2mm
0.6mm	1.8-2.5mm	40mm/s	0.2mm
0.8mm	2.0-3.0mm	40mm/s	0.2mm
1.0mm	2.0-3.0mm	40mm/s	0.2mm

🌡️ 6. Bed Temperature Settings

Bed Temperature:

Small parts: No heating (room temperature)
Large parts: 50-55°C

❄️ 7. Cooling Settings

Cooling Configuration:

General: 0% (fan off)
KEEP FAN ALWAYS: OFF
Force fan speed for overhangs and bridges: OFF
Layers < 20 seconds: 50% 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.
