Effects of Temperature on 3D Printing Filaments: PETG And PLA

When it comes to 3D printing, PLA and PETG filaments are popular choices. However, a crucial part of working with these filaments is knowing the precise temperature requirements. While many 3D printers, filaments, and 3D printing supplies are easily accessible to business owners, perfecting the process requires a deep understanding of how the materials react to temperature changes. Here is a guide to help you understand how to set the ideal PLA and PETG temperature and the common issues encountered due to 3D printing at high and low temperatures.

Common Issues Encountered During 3D Printing!


Warping is the curling of the final print that can make it look disproportionate or unappealing. When the printing temperature for PLA or PETG is set differently at each layer or if the completed layer does not cool down uniformly after extrusion, then warping occurs. For a professional or detailed 3D print, it is best to prevent warping and take appropriate measures.

Heat Creeps

A potential problem that you will encounter while 3D printing is heat creeping. It usually occurs when the heat unfolds on an irregular basis throughout extrusion. The heat creeps up quickly through the hot-end before the filament melting point and causes clogs, early swells, and deformed prints. Hence, it is crucial to regulate PLA and PETG bed temperature and extrusion temperature to ensure that the heat is not set too high.

Droopy or Messy Prints

If your 3D prints appear saggy, then excessive heat is the problem. As with higher PETG and PLA bed temperatures, you should also regulate the extrusion temperature. Alternatively, if the filament layers do not stick to the bed, it means the bed temperature is too low. Top Tips to Perfect PETG And PLA Bed Temperatures!

Working With PLA Bed Temperature

  • Although PLA is easier to work with, when compared to ABS and PETG, you need to experiment continuously to achieve the perfect print temperature. The ideal range for the extruder is between 190 to 220 ℃. However, make sure that the extruder is not too hot as this can make the filament soft and droopy.
  • The best temperature range for the heating bed is between 50 to 70 ℃.
  • While 3D printing with PLA, ensure that you get an enclosure so that external factors don't spoil your print.

Working With PETG Bed Temperature

  • PETG bed temperature will be higher than that of PLA. In general, on the hot end, you should keep the temperature range between 220 to 250 ℃.
  • One of the benefits of working with PETG 3D printer filament is that it does not warp often. However, it is prone to stringing. Furthermore, with excessive cooling, you can delaminate the layers. Hence, ensure that the cooling process is precise, and you store filament in a dry and moisture-free environment.
  • It is ideal to set the heat bed temperature between 55 to 70 ℃.
