The print does not adhere to or only partially adhered to the platform during the printing process. Non-adhesion occurs when the print or parts of the print fail to adhere to the platform at the start of the first layer of printing.
The most common problems are listed below about the models are not adhered during the printing process:
Completely non-adhesive: the model is completely not on the platform, and there is a piece of cured resin at the bottom of the resin tank.
Partially non-adhesive: the base of the model seems to be separated from the platform.
The model falls into the resin tank completely, leaving nothing on the platform.
The following any one or more of the factors may cause the model not to adhere:
Without supports during the printing process.
The first layer curing time is too short to withstand the peeling strength.
Debris/turbidity/damage in the resin tank
The screen of the printer is contaminated
The height of the platform needs to be adjusted
The primary task of successful troubleshooting is to determine the potential causes. The following list can be used to identify and solve the model problems. It includes finding out all kinds of possible reasons, from the most possible reasons to the most impossible reasons.
Step 1: add supports during the printing process
Because the bottom of most models are uneven, the model should not be printed without supports added at the bottom as far as possible.
Step 2: check the surface area of the model
If you print directly on the platform, please pay attention to the surface area of the first layer of the model.
If the surface area of the first layer is too small, the force generated by the peeling process will separate the printing layer from the platform. At this time, please adjust the printing angle.
Step 3: check the resin tank
Any debris, turbidity and/or damage in the resin tank will hinder ultraviolet light transmission, thereby limiting the printer's ability to fully cure the resin.
The spatula in the post-processing kit can be used to check if there is any debris in the resin tank. If so, the spatula can be used to remove all debris and cured resin in the tank, or the resin can be filtered.
It is very important to keep the resin tank clean and in good condition for successful printing.
Step 4: Check the height of the platform
If the space between the platform and the resin tank is insufficient or too large, the printer cannot fully compress the first layer to ensure a good adhesion between the curing layer and the printing platform. At this time, you need to readjust the height of the platform.
