HT gives best results on a heated build platform, 100 °C to about 120 °C is usually needed for proper adhesion to a glass plate. When this is not enough it’s possible to use buildTak plate for stronger adhesion. To master the HT material you should fine tune the first layer settings in order to prevent warping of printed parts. The suggested 3D print speed is around 30 - 50 mm/s.

When printing colorFabb HT we recommend 0% cooling whenever the model geometry allows for this. Don’t forget to adjust the minimal layertime, around 8/10 seconds should be fine. This will results in parts with optimal layer adhesion and also less chance of warping of the parts.

Due to all the different types of hot-end it's extremely difficult to give a temperature advice. Please consider our tips as a starting point to find the temperatures that work well in your setup. You may have to adjust the temperature settings slightly based on your type of printer.
