1Object-affected harmful factors
If the drying unit temperature is controlled to a set temperature based on low-heat resistance printing material, then low-heat resistance material is protected from damage, but high-heat resistance printing material dries slower
Solution Approach 1:
The drying unit temperature is made dynamically adjustable based on the heat resistance characteristics of the printing material being used. The control section receives information about the printing material type and automatically adjusts the drying temperature to match the material's heat resistance, enabling optimal drying speed without damage risk.
Solution Approach 2:
The drying temperature parameter is changed according to the printing material type. The system stores multiple temperature settings corresponding to different printing material heat resistance levels and selects the appropriate temperature parameter based on the material being processed, allowing efficient adaptation to various materials.
