tips to properly adhere the first layer

The adhesion of the first layer is essential in the 3D printing process because it secures the quality and success of the print.

In this article, you will find a list of procedures and tips that will help you get the print to adhere correctly to the build plate. With these tips you will avoid different problems that occur in the first layer.

What are first layer problems and why do they occur?

Mainly, there are three types of first layer problems: warping, elephant foot, and incorrect Z-axis calibration.


Warping is the partial lifting of some areas of the piece from the printing surface. This can be caused by a violent contraction of the material or a wrong calibration of the Z-axis.

This phenomenon can be differentiated when the first layer is not sufficiently attached to the printing surface or the piece "curves" after a while.


Elephant's foot refers to an excess of material in the first layer, commonly caused by a poor Z-axis calibration, as the hotend does not have the proper distance to extrude the material.

You will detect this problem if when you print the first layer you see that the material is very stuck and has a translucent appearance.

 

How to ensure the correct adherence of the piece

1. Calibrate the Z height of both heads

Make sure the nozzle distance is right by calibrating the Z height, go to Utilities / Calibration / Printer Calibration, and follow the steps that the screen shows. These articles will help you get it in the sweet spot:

2. Choose the right adhesive

choosing the right adhesive for each application

 

Every material is different and has different properties, this also translates to adhesive compatibility. For example, Magigoo Original works great for PLA and ABS, but it's not so good at sticking on PA. Check out each filament tutorial to find the right adhesive for each filament.

PLA ABS PAHT CF15
PVA PA PP GF30
PET-G PP  
TPU    
Tough PLA    
BVOH    

3. Make sure the printing surface is hot enough

Some materials will need a certain temperature in order to stick on the printing surface. Check that the printing surface is at that temperature. As a tip, let the printing surface heat up about 5 minutes before printing to ensure the build plate has an even temperature.

Recommendations:
General

Increase the temperature of the build plate gradually in steps of 5ºC to improve the filament adhesion.

Materials

 

Tough PLA

PLA

It is not recommended to exceed in more than 5ºC the temperature of the build plate due to possible deformations in the material

4. Some materials need a warm environment to be printed

ABS, PA, PP, and PPGF30 have a high contraction ratio, this makes them likely to warp up if they are cooled unevenly. This generates the need of an enclosed build volume. 

 

Recommendations:
Materials  

PP GF30 | PP

PAHT CF15

PA | ABS

Preheat the build plate at least 10 minutes before starting to print to make sure that the entire printing chamber is properly heated

Make sure to avoid any air current around the printer and that the room temperature is between 15ºC and 30ºC.
