Finding the right temperature settings for PLA printing can be a bit tricky. PLA is a versatile material and is generally forgiving when it comes to temperature, but different colors and brands of PLA may require different settings. In this guide, we’ll cover the ideal temperature range for both the hot end and the print bed, as well as common signs that the temperature needs to be adjusted.
For the hot end, the general range for PLA is between 180-220°C. If your layers aren’t sticking together, heating up the hot end can usually fix the issue, but be careful not to overheat the extruder, as this can cause the PLA filament to become too soft and result in messy or droopy prints. Signs that the hot end is too hot include difficulty with bridging (horizontal printing to connect two raised parts of a model) and prints not sticking to the bed. Experimentation is key to finding the ideal temperature for the specific filament you’re using.
For the print bed, the recommended temperature is around 60°C, but the best range for PLA is between 55-70°C. If your prints aren’t adhering to the bed, it’s likely the bed is too cold and needs to be heated up. However, be careful not to overheat the bed, as this can cause “elephant’s foot”, a distortion caused by the first layers of the print melting and then being squished by the weight of the print. Additionally, part cooling is also an important consideration, as it can help prevent distortions caused by the filament staying soft as it cools.
Another important factor is the layer height and print speed. Lower layer heights and slower print speeds can result in better quality prints, but they also increase the overall print time. Experimenting with different settings and observing the results can help you find the right balance between print quality and speed.
Finally, proper calibration of your 3D printer is essential for achieving good results with PLA. This includes proper leveling of the print bed, proper alignment of the nozzle, and proper calibration of the extruder. It is also important to check for any mechanical issues or jams that can affect the print quality.
In conclusion, finding the best PLA bed and print temperature settings takes a bit of trial and error, but with the right approach and attention to detail, you can achieve high-quality prints with PLA. Remember to keep in mind that different brands and colors of PLA may require different temperature settings and that proper calibration and maintenance of your 3D printer are essential for achieving good results.
