Every PETG brand prints differently. A temperature tower test quickly identifies the optimal settings for your specific filament, preventing hours of failed prints and wasted material.
What Is a Temperature Tower
A temperature tower prints identical sections at increasing temperatures — typically 220°C to 260°C in 5°C increments. Examining each section reveals which temperature produces the best results for your specific filament.
What to Look For
Check each temperature zone for: stringing (too hot), poor layer adhesion (too cold), surface quality, overhang performance, and bridging. The best zone balances all factors.
Running the Test
Download a standard temperature tower model. Configure your slicer to change temperature at each section height. Run the print unattended. Total print time: approximately 30-40 minutes.
Interpreting Results
The ideal temperature zone shows no stringing, excellent layer adhesion, smooth surfaces, and clean overhangs. If no single zone is perfect, choose the temperature closest to the best overall quality.
Document Your Results
Record optimal temperatures for every filament brand and color you use. Build a settings database over time. This small upfront investment prevents countless failed prints.
