Frequently Asked Questions

filament will tend to separate from the build platform as it cools.
This is an important fact to keep in mind as you print your first
layer. If you notice that the layer seems to stick initially, but later
separates from the print bed as it cools, it is possible that your
temperature and cooling settings are to blame.
Many printers that are intended to print high-temperature
materials like ABS include a heated bed to help combat these
problems. If the bed is heated to maintain a temperature of 110℃
for the entire print, it will keep the first layer warm so that it does
not shrink. So if your printer has a heated bed, you may want to try
heating the bed to prevent the first layer from cooling. As a
general starting point, PLA tends to adhere well to a bed that is
heated to 60-70℃, while ABS generally works better if the bed is
heated to 100-120℃. You can adjust these settings in Cura by
clicking on “Edit Process Settings” and then selecting the
Temperature tab. Choose your heated build platform from the list
on the left-hand side and then edit the temperature set point for the
first layer. You can just double-click on the value to change it.
If your printer has a cooling fan, you may also want to try
disabling that cooling fan for the first few layers of your printer so
that the initial layers do not cool down too quickly. You can do
this by clicking “Edit Process Settings” and going to the Cooling
tab. You can adjust the fan speed setpoints on the left-hand side.
For example, you may want the first layer to start with the fan
disabled and then turn on the fan to full power once you reach the
5th layer. In that case, you will need to add two setpoints into that
list: Layer 1 at 0% fan speed, and Layer 5 at 100% fan speed. If
