In the process of using LCD 3D printer, many customers will encounter the phenomenon of fault. We must find the problem and solve it. We may not carefully check some steps in the process of use. So we need to check some of our operations.

The model is broken or cracked during printing. The main reasons are as follows:

1. During slice operation, there are abnormalities at the fracture layer, including missing edge, the slice layer disappears, and the slice shape is inconsistent with the model.

2. The model is interrupted in the printing process, and the crack layer is disturbed, including consumables and impurities, lack of support or the model slice separated from the support falls off and walks away at the printing position. It is just in the slice position to truncate the model.

3. The layout of printing model and the area size are extreme. There will be more fractures. When a large model is placed together with a slender model, the fault rate of the slender model will be relatively high. Because under the same conditions and printing time. The large model is easier to form than the small model, so the thickness of each layer of the large model is later than that of the small model.

4. It is also possible that the position of the fixed platform and chute is not checked during printing, resulting in a little shaking of the platform or chute.

After printing time. When the cumulative thickness of large model and small model increases gradually, it is possible that the small model is disconnected in one layer. Failure to print later.

resolvent:

1. Check whether there is a problem with the slice. If there is a problem, please use professional software such as magics to repair the STL file or remake the print file.

2. Use the material tray cleaning function of the printer to clean the material tray first and then. Filter the impurities of consumables again, and check the forming platform to keep the flatness of the forming platform. Print again.

3. Printing large objects and small slender objects separately is the best solution. If you must print together, first adjust the printing time. The length of time is based on small slender objects. (example: large models are formed in 8 seconds and small models are formed in 12 seconds, which must be printed in 12 seconds). However, in the case of overexposure, large models may cause shrinkage deformation or increase and thickening of size deviation.

4. Before printing, be sure to tighten the screw positions of the fixed chute and platform to prevent shaking during printing.
