First layer non-adhesion is one of the most common problems in 3D printing. Just as the foundation of a house is not stable when it is built, when the first layer of the print is not successfully adhered to the glass plate, the printing task will probably fail.
¶ Possible Causes
-
The calibration is done improperly.
-
There is dust or stain on the surface of the glass plate.
-
There is filament residue on the nozzle.
-
There is foreign object on the heated bed surface.
-
The printing parameters are improper.
-
The quality of filaments is not up to standard.
¶ Solutions
- Recalibrate the heated bed.
a) On the touchscreen, tap Calibration > Heated Bed Leveling to recalibrate the heated bed.
b) After the leveling is completed, tap Calibration > Calibration Check, and print the calibration model to check whether the calibration is successful. If unsuccessful, repeat the previous step.
-
Clean the glass plate (refer to Cleaning the Glass Plate).
-
Clean the nozzle (refer to Cleaning the Nozzle).
-
Clean the heated bed (refer to Cleaning the Heated Bed).
-
Reset the following printing parameters on the Snapmaker software:
a) Set the Heated Bed Adhesion Type as Brim. Brim can effectively improve the first layer adhesion. Also, you can increase the line count to improve adhesion.
b) Lower the Initial Layer Print Speed.
c) Increase the Initial Layer Height.
d) Increase the Initial Layer Line Width.
e) Set a proper Heated Bed temperature as required by each filament.
f) Set a proper orientation and angle for the model to maximize its contact area with the glass plate.
-
Check whether the filaments have quality problems such as moisture (refer to Filament_Library). If any, dry the filament or replace it with a new filament and try again.
-
If poor adhesion persists, apply a thin layer of liquid glue on the glass plate before printing. For the purchase link for liquid glue (type the keywords in the search box), as well as the reasons why we recommend using liquid glue instead of glue stick, please visit our online store.
