Symptom: The first layer of your print is not printing at a consistent thickness. In most instances, getting that first layer to adhere is 90% of the battle. An unleveled bed is the first and most common cause of first layer curling. Raising the feed rate and z offset can decrease the hot filament's tension at the nozzle's tip and the surface layer . Firstly, the bed needs to be parallel to the plane the nozzle traverses when moving in X and Y. Continue leveling around all the corners. At first I had inconsistencies between and within prints. The first layer looks horrible, and all other layers are fine. 3. help Reddit coins Reddit premium. If your filament is being squished until it is paper-thin, to the point that it sometimes does not come out or appears pulled, you are probably too close, so increase your distance (a little at a time). Check out how Simplify 3D makes the first layer thin to ease the brim removal process. Three of the most popular topics in 3D printing are bed leveling, first layer thickness, and Z-offsetand for good reason. That "squish" helps the first layer adhere better as the filament is force downwards instead of printing as a full bead. Some notes and hardware troubleshooting tips are still Voron specific, however. Join. A higher temperature will allow the plastic to melt better and adhere to the bed, so try bumping up the nozzle and bed temperatures by around 5 C each. This distance creates a small "squish" in the first layer of printing. The reason 3D prints stick to the bed too much is because there is a strong bond between the two materials, mixed in with the temperature. Other options are Elmer's glue stick, a glue stick specified for a 3D printer bed, or hair spray. In the world of 3D printing, PETG has often been touted as representing the best of both worlds of the top two most popular filaments, PLA and ABS. . 1. General Principles.
