PP3D Polypropylene, developed in collaboration with Repsol, represents a breakthrough in 3D printing materials. This high-quality thermoplastic polymer benefits from Repsol's extensive expertise in polyolefin manufacturing, delivering exceptional fatigue resistance, high toughness, and low friction coefficient. Each spool comes with a specialized adhesion primer that enables strong bed adhesion at just 40°C on glass surfaces, effectively eliminating warping issues.

What sets PP3D apart is its injection-molding-like finish that minimizes visible layer lines, resulting in professional-grade parts with exceptional surface quality. The material is non-toxic, autoclavable, and food-safe, making it perfect for end-use applications. Its outstanding chemical resistance and mechanical properties make it ideal for functional prototypes and industrial components that require reliability and durability.

PP3D Printing Guide

PP3D Applications

Printing Parameters

Complete Technical Printing Guide - PP3D

🌡️ 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 PP3D

Polypropylene (PP3D) is a semi-crystalline polymer known for its excellent chemical resistance, fatigue resistance, and good electrical insulation properties. Its low density and high flexibility make it ideal for living hinges and durable parts.

Nozzle	Layer Height	Line Width	Volumetric Speed	Temperature
0.4mm	0.2mm	0.42mm	5.0 mm³/s	240°C
0.6mm	0.3mm	0.62mm	16.2 mm³/s	242°C
0.8mm	0.4mm	0.82mm	28.8 mm³/s	245°C
1.0mm	0.5mm	1.02mm	45.0 mm³/s	248°C

🚀 4. Speed Settings

⚠️ NOTE: PP3D benefits from consistent speeds to maintain uniform crystallization and prevent warping. The following speeds are calculated based on the volumetric speeds listed in the basic parameters section.

0.4mm Nozzle (Volumetric Speed: 5.0 mm³/s)

Line Type	Percentage	Speed
External Perimeter	50%	29.76 mm/s
Internal Perimeters	75%	44.64 mm/s
Infill	100%	59.52 mm/s
Top/Bottom	60%	35.71 mm/s
First Layer	30%	17.86 mm/s

0.6mm Nozzle (Volumetric Speed: 16.2 mm³/s)

Line Type	Percentage	Speed
External Perimeter	50%	43.55 mm/s
Internal Perimeters	75%	65.32 mm/s
Infill	100%	87.10 mm/s
Top/Bottom	60%	52.26 mm/s
First Layer	30%	26.13 mm/s

0.8mm Nozzle (Volumetric Speed: 28.8 mm³/s)

Line Type	Percentage	Speed
External Perimeter	50%	43.90 mm/s
Internal Perimeters	75%	65.85 mm/s
Infill	100%	87.80 mm/s
Top/Bottom	60%	52.68 mm/s
First Layer	30%	26.34 mm/s

1.0mm Nozzle (Volumetric Speed: 45.0 mm³/s)

Line Type	Percentage	Speed
External Perimeter	50%	44.12 mm/s
Internal Perimeters	75%	66.18 mm/s
Infill	100%	88.24 mm/s
Top/Bottom	60%	52.94 mm/s
First Layer	30%	26.47 mm/s

↩️ 5. Retraction Settings

🚀 IMPORTANT: PP3D requires precise retraction settings to prevent stringing while maintaining consistent flow. Lower retraction speeds help prevent filament grinding, while Z-hop helps prevent nozzle marks and improves overall print quality.

Nozzle	Distance	Speed	Z-Hop
0.4mm	0.8-1.2mm	30mm/s	0.2mm
0.6mm	0.8-1.2mm	30mm/s	0.2mm
0.8mm	0.8-1.2mm	30mm/s	0.2mm
1.0mm	0.8-1.2mm	30mm/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

🌡️ 6. Bed Temperature Settings

Print Surface Requirements:

Recommended surface: Clean glass bed + PP3D Primer
First Layer Temperature: 40°C with PP3D Primer
Removal Temperature: 85°C
Chamber Temperature (if available): Room temperature with no drafts

How to Use Recreus' PP3D Primer

Step-by-Step Application Guide:

Step 1 - APPLY

Open PP3D Primer bottle
Apply directly to print area
Ensure even coverage

Step 2 - DRY

Wait minimum 5 minutes
Allow primer to dry completely
Avoid touching prepared surface

Step 3 - HEAT

Set bed temperature to 40°C
Maintain this temperature during printing
Do not exceed 40°C to prevent deformation

Step 4 - REMOVE

After print completion, heat bed to 85°C
Remove part carefully
Let bed cool before next application

Cleaning & Maintenance

Clean residue with Sanytol or acetone
Store primer bottle tightly sealed
We recommend to use a dedicated buildplate for Polypropylene printing

❄️ 7. Cooling Settings

Cooling Configuration:

Base Fan Settings:

First Layer: 0% (fan off)
General Printing: 0% base fan speed
Layers < 10 seconds: 30% fan speed
Minimum Layer Time: 10 seconds

Advanced Settings:

Keep Fan Always On: OFF
Force Fan Speed for Overhangs: OFF
Bridge Fan Speed: 30%
Maximum Fan Speed: 30%

Layer Time Goals:

Minimum Layer Time: 10 seconds

Critical Considerations:

PP3D requires minimal cooling for optimal layer adhesion
Only use cooling for bridges and overhangs
Gradual fan speed introduction helps prevent warping
Enclosed chamber helps maintain consistent temperature

Temperature Control Tips:

Keep printer in draft-free environment
Use enclosure if available to maintain stable temperature
Monitor first few layers closely for proper adhesion
Adjust fan speed based on part geometry and size
