Chapter 7 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 the print is suspended where it is empty, the printed
filament will sag. So when printing, you need to use software to generate support, and
then remove the support after printing. Similar to building a house, the concrete will fall
down because it is fluid. Therefore, it is necessary to lay a stake before building the house.
When the concrete is solidified, the stakes are removed.
Like the construction, The removal of the stake will leave its traces, after printing will
also leave some traces of the support. So if you want to improve the print quality, you
need to avoid the vacant places as much as possible, and you can improve it from the
following two points.
一、
Avoid overhang by changing the print position
