The working principle of the mode that the double-nozzle simultaneously prints two same models is as follows:
referring to fig. 1, when the distance between the two Z-axis systems in the X direction is exactly half of the distance between the entire printing platform, the printer can work in a mode that the dual nozzles print two identical models at the same time. As mentioned above, the distance between the two Z-axis systems can be adjusted by the motor motion of the two Z-axis systems independently. The double Z-axis driving motors run in the same direction in the printing process. The mode can realize the function that two nozzles print the same model at the same time, and the mode can improve the printing efficiency. The method is suitable for the condition of large number of models.
The working principle of the single-nozzle printing mode is as follows:
referring to fig. 4, when one of the Z-axis systems stops at the origin position, and the Z-axis system rises to the highest limit position by adjusting the zero switch, the movement of the Z-axis system is stopped. At this time, single nozzle printing of parts can be realized. In this mode, the stopped Z-axis system does not move to the left or right simultaneously with the operating Z-axis system, but rather one is parked at the zero position. This mode adaptation is used in situations where the printed object is small in volume, does not require water soluble supports, or is inexpensive in material. This mode allows printing of the object with minimal energy consumption.
The working principle of a model mode of double-material co-printing by double nozzles is as follows:
referring to fig. 5, when the two Z-axis systems are stopped together and the positions of the respective Z-direction zero switches are adjusted to the same horizontal height, the two Z-axis system lifting motors are connected in parallel, so that dual-nozzle dual-material printing can be realized. This mode is the primary mode of operation for that model. The operation of printing the same model with two materials can be performed. This mode may also be referred to as a two-material, two-out printing mode, and the printed models are divided into two types: first, the support portion of the mold is printed with an inexpensive material and the body portion of the mold is printed with the desired material. Is beneficial to saving the cost. Second, the support portion of the mold is printed with a water-soluble material and the main portion of the mold is printed with the desired material. The peeling of the model supporting part and the main body part is facilitated.
The working principle of the mode that the double spray heads move in opposite directions to print two same models is as follows:
referring to fig. 6, when the distance between the two Z-axis systems in the X direction is exactly half of the distance between the entire printing platform, the printer can work in a mode that the dual nozzles print two identical models at the same time. As mentioned above, the distance between the two Z-axis systems can be adjusted by the motor motion of the two Z-axis systems independently. The double Z-axis driving motors run reversely in the printing process. The mode can realize the function that two nozzles print the same model at the same time, and the mode can improve the printing efficiency. The method is suitable for the condition of large number of models.
It should be noted that, the lead of the lead screw is an integer, such as 2 mm or 4 mm. The distance between the two Z-axis systems can be determined by the lead of the nut and the lead screw, and the two Z-axis systems are different in distance and are different in adaptive printing modes.
In addition, the model can print a single-color double-material model, can print a double-material water-soluble support model or can print a double-color double-material model under the condition that double materials for double nozzles are printed in a model mode.
To sum up, the utility model provides an independent dual spray three-dimensional inkjet printer 100 of single platform has following characteristics:
