How to Print ABS Filament Successfully
ABS is a versatile thermoplastic known for its strength, heat resistance, and post-processing flexibility. However, it can be tricky without proper prep. Follow this guide to maximise print quality and minimise warping.
1. Dry the Filament
- Before printing, ensure your ABS filament is thoroughly dried at 60°C for 4+ hours using a filament dryer or oven.
- Moisture leads to bubbles, weak layer adhesion, and poor surface finish.
2. Preheat the Printer
- Preheat your printer for at least 30 minutes before starting the print.
- This stabilises internal temperatures and reduces thermal shock, especially inside enclosed chambers.
3. Prepare the Print Surface
- Apply a liberal layer of glue stick to the build plate while it’s warm.
4. Print Settings
- Nozzle Temperature: 250–270°C
- Bed Temperature: 100–110°C
- Cooling: Turn off fans or set them very low—ABS needs gradual cooling to prevent warping.
- Print Speed: Moderate (40–60 mm/s recommended)
5. During the Print
- Avoid airflow around the printer—no open windows or fans.
- Monitor for corner lifting; add brim for extra layer of adhesion.
6. Post-Print Handling
- Once the print finishes, allow it to cool completely before removing it from the bed.
- Removing it too early risks cracking due to ABS shrinkage as it cools.
