Polycarbonate is a popular thermoplastic material used in 3D printing due to its unique properties and benefits. It is a strong and durable material that can withstand high temperatures and has excellent impact resistance. However, printing with polycarbonate can be challenging, and it requires specific settings and techniques to get the best results. In this article, we will explore how to get the best results when 3D printing with polycarbonate.
- Printer Settings
Polycarbonate requires high temperatures to melt and flow correctly, so it is essential to set the printer to the appropriate temperature range. The recommended temperature range for printing polycarbonate is between 260°C and 310°C. It is also crucial to use a heated bed and set the temperature between 100°C and 120°C to prevent warping and ensure adhesion to the bed.
- Filament Quality
When 3D printing with polycarbonate, it is essential to use high-quality filament. Inferior filament can cause issues such as clogging, inconsistent flow, and poor layer adhesion, leading to a low-quality print. It is best to use filament from reputable manufacturers that have high-quality standards.
- Bed Adhesion
Bed adhesion is a critical factor when printing with polycarbonate. Polycarbonate can warp during the printing process, so it is essential to ensure the bed is level and clean. Using a bed adhesive such as BuildTak or Kapton tape can also improve bed adhesion and prevent warping.
- Cooling
Polycarbonate requires slow cooling to prevent cracking and warping. It is recommended to keep the cooling fan off during the printing process or set it to a very low speed. Rapid cooling can cause the layers to contract unevenly and lead to a poor-quality print.
- Post-Processing
Polycarbonate is a robust material that can be difficult to post-process. Sanding and polishing may be necessary to achieve a smooth finish. Using a heat gun or a hot air gun can also help to remove any blemishes or inconsistencies on the surface of the print.
In conclusion, 3D printing with polycarbonate requires specific settings and techniques to achieve the best results. Printer settings, filament quality, bed adhesion, cooling, and post-processing are all critical factors that must be considered. By following these guidelines, 3D printing with polycarbonate can produce strong, durable, and high-quality prints.
