Printing tips
The principle of the FDM type 3D printer determines its printing characteristics. Only
by mastering these characteristics can the ideal graphics be printed better. The main
conclusions are as follows:
7.1
Flat bottom
When printing, select the bottom side to be flat.
Since printing starts from the bottom and prints
layers, the bottom layer determines the print
quality of the object, Therefore, printing the
bottom layer is the most important. Choose a flat
bottom as the underlying print is a key to the
success of the print.
7.2
Avoid overhang
Since the filaments spilling out of the nozzle during printing are fluid, they will droop
under the influence of gravity, if there is any overhang in the printed image, the filament
will drop down, therefore, we need to use software to form a support when print, and
remove it after print is done. It is same as building a house, because the concrete is fluid
which will drop down, so we need stake it off, and remove the wooden stakes after the
concrete is consolidated.
Same as construction, after removing the wooden stakes, it will leave the stake marks.
So after print finish, the support mark will be there. So if you want to improve the print
quality, you need to avoid overhang as much as possible to improve, the following two
aspects must be done:
一、
Avoid overhang by changing the print position
Overhang appears which red arrow
points to in the right image.
