Do Higher Print Temperatures Produce Better Printed 3D Parts?

Alex DanisMay 09, 2020

Finding the perfect TPU temperature for 3D printing is quite a challenge! If you have wished several times for a standard temperature that you could just set on your printer and wait for the perfect prints, it ain't happening. Finding the perfect temperature for printing can be achieved through a trial and error process only.

However, a research paper has stated that products that have been 3D printed at higher temperatures have smaller air gaps and, hence, are stronger as compared to those that are printed at lower temperatures. To know more about finding the right temperature, read on.

Temperature Ranges for the Hot End

For PLA, there's a range of temperatures that you will have to work with to explore and find the right temperature. In the case of PLA, the range varies from 190 degrees to 220 degrees Celsius. For instance, Proto-pasta's High Temp PLA v2.0 prints with ease but has a potential Heat Deflection Temperature (HDT) of as much as 140C (285F) depending on post-processing. This means parts retain more stiffness and form at higher temperatures.

Here are a few tips to help you handle the hot end to achieve the best results

  • Heat the hot end more if your layers aren't adhering to each other
  • Keep in mind that the extruder should not become very hot. If it does, it will cause your PLA to become too soft. This results in messy and droopy prints
  • If the hot end is too cool, your prints will not stick to the print bed. It will also result in difficulty in making tight corners in your prints

The Best Range for a Heated Bed

Heated beds are extremely important in 3D printing. You may have to explore to find the perfect TPU bed temperature too. Usually, the recommended temperature is 70 degrees Celsius, but do experiment in the 50 degrees to 70 degrees Celsius to find the optimal 3D print temperature.

How To Know if the Heated Bed is at the Right Temperature?

If your prints are not sticking to the print bed, it is a clear indication that your ABS bed temperature or PLA bed temperature is not right. You can slowly adjust the temperatures to make it warmer and allow the plastic to stick.

On the contrary, if your heated bed is too hot, it can result in a defect called the 'Elephant's Foot.' This can be avoided by reducing the temperature of the bed.

What is the Best Way to Find the Perfect Temperature?

The best way to find the perfect filament temperature for 3D printing is to experiment. While you can tell from defects such as the Elephant's Foot and failure of the prints in sticking to the print bed and set the temperature accordingly, you must also keep in mind that different filaments and brands have different printing temperatures. For instance, a spool of blue PLA filament will print best at a different temperature from a spool of black PLA filament.
