Page 25: Start Slicing
Step 2 Start slicing The MD-400D is an independent dual nozzle 3D printer that can be switched between three modes on the machine. They are duplicate mode, mirror mode and free mode. During the process of using MINGDA CURA, users will have four different usages: duplicate mode, mirror mode, print support, and print dual color. - Page 26 Mirror Mode X * Y * Z: 170 * 400 * 400mm Printing size: Mirror mode printing process: Slice a single nozzle, select Mirror mode on the machine, and then print. Note 1: When selecting mirror mode, the sliced model can only be located on the left side of the red line, with a size of 170mm.

Reminder: When performing support printing, Extruder 1 uses the materials required for the model, while Extruder 2 uses the supporting materials matched with the model materials. - Page 28 The type of support and platform attachment can be specified according to one's own needs, which print head to use. Select print head 2 here...
- Page 29 Click Slice, click Preview, select material color As can be seen, the wine red area is the main body of the model, which will be printed by Print Head 1, while the purple area is the support and bottom valve, which will be printed by Print Head 2. Print head 1 and print head 2 can set different printing parameters such as printing temperature and printing speed to achieve the application of water-soluble support and easily peelable support.

Page 33: Tips For Printing Support And Dual Color Models
Tips for printing support and dual color models 1. Import the model to be printed, right-click on the model, select Extruder 1 to print the model, start the support, and select Extruder 2 to print the support. 2. Adjust the "standby temperature" in the "Material" interface. Standby temperature: The unprinted nozzle will drop to the set temperature during the printing process For example, suppose the left nozzle is in an idle state when printing, but due to the high... - Page 34 3.You can select the type of base plate attachment in the "Print Platform Attachment" tab. Additional types of base plates include Raft, Brim, and Skirt. Raft prints several layers of valve body similar to the base structure before printing the model. This function can enhance the adhesion between the model and the printing base plate, reducing the risk of model warping;...
- Page 35 4. Double extrusion: Start the filling tower Due to the fact that there is always a printer in standby mode during the printing process, it is easy to cause defects such as wire drawing and material leakage. After starting the loading tower, the extruder will print on the loading tower before each printing, printing any material leakage on the printing head on the tower, effectively avoiding the phenomenon of material leakage when replacing the extruder.
