AI Technical Summary
In traditional 3D printing processes, insufficient interlayer bonding strength and high internal porosity make it difficult for existing temperature control methods to achieve deep interlayer molecular fusion at the microscale, resulting in poor print quality.
An ultrasonic rolling temperature-controlled nozzle is used, combined with an ultrasonic rolling mechanism and a temperature control component. Ultrasonic vibration and temperature control are carried out simultaneously to ensure that the material is formed under the optimal process parameters.
It significantly improves the interlayer bonding strength and surface quality, and achieves material densification and efficient forming.
