2. Material Properties (TDS)
(Note: Values rounded to the nearest integer where applicable, excluding percentages).
| Property | Standard | Typical Value |
|---|---|---|
| Density | ISO 1183 | 1.15 g/cmΒ³ |
| Water Absorption | ISO 62: Method 1 | 0.4% |
| Melting Temperature | ISO 11357 | 168Β°C |
3. Recommended Printing Conditions
To achieve optimal adhesion and print quality, start with these baseline settings and adjust based on your specific printer and environment.
| Parameter | Recommended Setting |
|---|---|
| Nozzle Temperature | 260-280Β°C |
| Build Plate Temperature | 70-90Β°C |
| Print Speed | 30-120 mm/s |
| Cooling Fan | OFF |
| Retraction Distance | 0.6-2 mm |
| Retraction Speed | 1800-3600 mm/min |
- Nozzle
- 0.4-1.0mm. Hardened steel nozzles (or higher grade wear-resistant nozzles) are recommended, alongside a heating block thickness of at least 12mm.
- Build Surface (Adhesive)
- Proper bed preparation is crucial to prevent warping. We strongly recommend coating your build plate with Siraya Tech Grip for optimal first-layer adhesion. PVP solid glue may also be used as an alternative.
4. Recommended Support Settings (Slicer)
Configuring your slicer correctly is critical for easy support removal and clean surfaces.
| Parameter | Recommended Setting |
|---|---|
| Support Infill | 15%-20% infill ratio |
| Dense Support Layers | 3-5 |
| Top and Bottom Z-Distance (Vertical Offset) | 0 mm |
| Horizontal/XY Distance | 0.3-0.6 mm |
| Support Wall Loops/Outlines | 0-1 |
| Raft Separation Distance | 0 mm |
5. Handling and Usage Guidelines
Moisture Management (Critical)
Support PET readily absorbs moisture from the air. Damp filament will cause oozing, bubbling, and rough surface extrusion, which can lead to print failures or difficult support removal.
Storage: Store the filament in a dry box with humidity below 15% immediately after opening. When not in use, reseal it in its original foil bag with desiccant.
Drying: If the material absorbs moisture, restore it by drying in a filament oven or dehydrator at 80-100Β°C for 4-6 hours before printing.
Bed Adhesion
Achieving a solid first layer is vital for successful dual-extrusion prints. Always apply an even layer of Siraya Tech Grip to your build surface prior to printing. This ensures both the main material and the Support PET anchor securely to the bed throughout the duration of the print.
Post-Processing and Annealing
Removal: Wait for the print to cool completely before removing the support material. It should peel away manually like tearing paper.
Annealing: If the main body material (like ABS or PET) requires annealing for strength, leave the Support PET attached during the thermal treatment. It will act as a physical scaffold, minimizing shrinkage and dimensional deformation. Remove the support only after the part has fully cooled.
