Why can't I print the whole part when printing resin?


#1

Have you tried to find that some parts of the model are not printed after resin printing? Do you know the reason?

Today we will discuss the causes and solutions of this problem.

We can discuss several aspects.

Sometimes during the printing process, it may be found that some small or thin parts of the model are missing. When this happens, the simplest solution is to appropriately increase the layer exposure time around 0.5-1s, as shown in the figure below In the Eiffel Tower, the details of the railing on the left are missing, and the details are printed successfully after increasing the layer exposure time.

The model bottom plate is printed successfully, but the support connecting the bottom plate is not printed successfully, as shown in the figure below.

It may be that the support is too thin or too little, which causes the model not to be pulled; or the lifting speed is too fast or the lifting distance is not enough, causing the model to fail to release.

In order to save material and reduce the weight of the model when printing the model, the model will be shelled, which causes the shell wall to be too thin, which leads to the loss of the model. In this case, the model needs to be reprocessed to increase the thickness of the shell. It is recommended that the thickness of the shell is more than 1.5mm.

If it is determined that it is not the problem of the model, please check whether there are dead pixels on the printer screen. If so, please replace the printer screen.

The peeling of the model and the release film is not good and the resin is underexposed. This situation usually occurs on large printed models. As shown in the figure below, the first half of the model is printed well, but some supports suddenly disappeared in the second half.

There are two solutions to this situation, one is to replace the release film of other brands, and the other is to slightly increase the layer exposure time from 0.5s to 1s according to actual needs.

If neither of the above two methods can improve the missing condition, you need to slice the model again. Pay attention to finding the best angle during the slicing process, and reduce the contact area between each layer of the model and the release film as much as possible to reduce peeling The purpose of force.

5.Large-size model printing is missing

Possible reasons: the release film is loose and the layer is underexposed.

Solution: Replace the release film or increase the exposure time of 0.5s~1s layer depending on the specific situation.

The figure below shows that the problem of missing model is solved after increasing the exposure time of 1s layer under the condition that the release film is normal.

6.Faults in printing of large-size models

Possible cause: Underexposed layer.

Solution: increase the exposure time of 0.5s~1s layer depending on the specific situation.

The picture below shows that the fault problem of the model is solved after the 1s layer exposure time is increased.
