Getting perfect prints can sometimes be a frustrating task. Several variables impact your 3D print quality. I like to lock down these pesky variables. Then I work through these variables. When I’m satisfied with the print quality I can begin printing. The first thing I look at is the hot-end temperature. Improper temperature can result in stringy filament or even oozing.
Temperature Calibration Tower
You can print a temperature calibration tower to help identify the optimal hot-end temperature. A temperature tower is a series of horizontal bridges that are printed between two columns. Each bridge has the temperature embossed on it. The bridge temperature corresponds to the temperature set within the G-Code. The hot-end temperature changes at each level of the tower.
To calibrate the filament observe how the print looks at each stage of the tower. Then select the temperature that give the best results. And note that the “Manufacturer’s Recommended” temperatures may not correspond to your optimal settings. Let the results speak for themselves.
Please be aware that this is filament specific. Even different color filament of the same series filament may have different ‘optimal temperatures’. This would require running this calibration for each color as well. This ensures the filament is at the correct temperature setting up the print to have the best chance of being successful.
