FIRST LAYER ADHESION PROBLEMS!!!

FIRST LAYER ADHESION PROBLEMS

This problem refers to a condition where the first layer of the print does not stick to the bed. This is one of the most common problems in 3D printing encountered by 3D printer users. 

The following is a list of 3D printing troubleshooting actions you can take to resolve the layer adhesion problems:

• Check the Bed Levelling

Before starting any print, it is important to check the bed levelling. If the bed is not levelled appropriately then the first layer may not stick to the plate.

• Check Bed Temperature

Check the temperature of the bed while starting the print. Some materials require a heated bed to ensure that the print sticks to the bed. The bed temperature can be easily controlled through all slicing software.

• Set Optimum Print Speed

Set the print speed to the optimum level. The print speed can significantly affect the layer adhesion. Faster the speed, lower the bed adhesion. The print speed settings can be found in the slicing software.

• Set the Fan Speed

Check the fan speed of the print. It is recommended to keep the fan speed low for the first few layers and in case of ABS switch off the fan completely.

• Adjust Nozzle Height

Nozzle height can also affect the layer adhesion. This is mostly a one-time adjustment where the nozzle height from the bed is adjusted to an optimum level. If the nozzle is too high from the bed then the deposited layer will not stick or even fall at the desired location. If the height is too low then the nozzle itself may scrape the deposited material.

• Use External Adhesive Agents

If layers are not sticking to the bed, then one solution to ensure proper layer adhesion is to use external adhesive agents like tape, glue or ABS slurry. All these can augment the layer adhesion property of the bed for the initial layers. This is a widely used method and almost always solves the problem.

• Use Bed Adhesion Tools

Slicing software also provides solutions to this dreaded common problems in 3D printing. Tools like ‘Brim’ and ‘Raft’ can significantly improve the adhesion properties of the part. These tools are found in all slicing software and using them can solve the adhesion issues to a far extent.
