Thermal Break Performance of Zirconia
Ceramic Support Columns on Dragon Ace™ and Orginal Dragon hotend
To experiment the replacement of thin-walled stainless steel metal support tubes with zirconia ceramics on Dragon Ace™ and Orginal Dragon hotend under the same conditions and observe the temperature change of the hotend body. To see which solution has a better thermal insulation effect.
Hotend: Dragon Ace™ (figure 1) Orginal Dragon (figure 2)
Mounting method:Trianglelab®DDE-RD (figure 3)
Cooling Fan:Noctua NF-A4x10 5V (figure 4)
Nozzle Temperature:260 ℃
Ambient temperature:28 ℃
Temperature measurement method: HIKMICRO K09 Thermal Imaging Camera
Zirconia ceramic support column:OD 2.3mm Length 7.5mm (Fig. 5)
Stainless steel support tube:OD 2.3mm Wall thickness 0.15mm Length 7.5mm
After installing the experimental setup, set the nozzle temperature to 260 degrees Celsius. Leave it for more than 20 minutes, wait for the temperature of all parts to stabilize, and use a thermal imaging camera to measure and record the temperature of the upper end of the hotend body. After replacing the support column of this hotend with a zirconia material one (figure 6), the temperature was again observed and recorded using the same method. Compare the temperature changes recorded on both occasions to verify if using a zirconia ceramic support column is a better solution.
