PP·GF (Glass Fiber Polypropylene), developed in collaboration with Repsol, represents a breakthrough in engineering-grade 3D printing materials. This composite filament combines lightweight polypropylene's corrosion resistance with glass fiber's exceptional tensile and flexural strength. The result is a high-performance material that delivers superior mechanical properties and durability, featuring a smoother finish than conventional glass fiber products.

Printing Parameters

Complete Technical Printing Guide - PP-GF (Glass fiber)

🌡️ 1. Material Preparation

Filament Drying (CRUCIAL):

📏 Temperature: 50°C
⏱️ Minimum time: 4-6 hours
💡 Proper drying is essential for optimal printing results and to prevent moisture-related issues

⚡ 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 PP-GF

Glass Fiber reinforced Polypropylene (PP-GF) combines the chemical resistance of PP with enhanced dimensional stability and reduced warping thanks to its glass fiber content. This material offers improved mechanical properties, better dimensional accuracy, and reduced thermal expansion compared to standard PP3D.

Nozzle	Layer Height	Line Width	Volumetric Speed	Temperature
0.4mm	0.2mm	0.42mm	4.5 mm³/s	245°C
0.6mm	0.3mm	0.62mm	14.6 mm³/s	247°C
0.8mm	0.4mm	0.82mm	25.9 mm³/s	250°C
1.0mm	0.5mm	1.02mm	40.5 mm³/s	253°C

🚀 4. Speed Settings

⚠️ NOTE: Due to the glass fiber content, lower speeds are recommended compared to standard PP3D to minimize wear and ensure proper layer adhesion. These speeds are calculated based on the volumetric flow rates for optimal fiber orientation and layer bonding.

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

Line Type	Percentage	Speed
External Perimeter	50%	26.79 mm/s
Internal Perimeters	75%	40.18 mm/s
Infill	100%	53.57 mm/s
Top/Bottom	60%	32.14 mm/s
First Layer	30%	16.07 mm/s

0.6mm Nozzle (Volumetric Speed: 14.6 mm³/s)

Line Type	Percentage	Speed
External Perimeter	50%	39.25 mm/s
Internal Perimeters	75%	58.87 mm/s
Infill	100%	78.49 mm/s
Top/Bottom	60%	47.10 mm/s
First Layer	30%	23.55 mm/s

0.8mm Nozzle (Volumetric Speed: 25.9 mm³/s)

Internal Perimeters	75%	59.56 mm/s
Infill	100%	79.41 mm/s
Top/Bottom	60%	47.65 mm/s
First Layer	30%	23.82 mm/s

↩️ 5. Retraction Settings

🚀 IMPORTANT: Due to the glass fiber content, PP-GF requires slightly lower retraction speeds compared to standard PP3D to minimize filament abrasion and prevent grinding. The fiber content also helps reduce stringing, allowing for shorter retraction distances.

Nozzle	Distance	Speed	Z-Hop
0.4mm	0.8-1.2mm	25mm/s	0.2mm
0.6mm	0.8-1.2mm	25mm/s	0.2mm
0.8mm	0.8-1.2mm	25mm/s	0.2mm
1.0mm	0.8-1.2mm	25mm/s	0.2mm

Additional Retraction Recommendations:

Minimum Travel for Retraction: 1.5mm
Maximum Retraction Count: 100
Minimum Extrusion Between Retractions: 1mm
Retract on Layer Change: Yes
Wipe Before Retraction: Yes
Use hardened steel nozzle to prevent wear from glass fiber
Monitor retraction settings and adjust if excessive stringing occurs

🌡️ 6. Bed Temperature Settings

Print Surface Requirements:

Recommended surface: Clean glass bed + PP3D Primer
First Layer Temperature: 40°C with PP3D Primer
