Understanding print bed adhesion
I was unsure whether to include this section or not, as it is a bit advanced for a beginner who wants to jump straight into printing, but on the other hand, it can be a lifesaver for many real-world scenarios.
The core of this section is how to improve the bond between the print bed and our part. As you may expect, if the printed part partially or fully detaches from the build platform while being printed, it becomes garbage in no time.
You may be wondering what may cause part detachments. The reason is pretty simple: thermal expansion (or shrinkage)! That’s why we have to understand the temperature distributions inside a printed part a bit better.
Thermal expansion and shrinkage
There is a key concept behind all the options we are about to discuss: every material on the planet shrinks and expands when cooling or heating occurs.
When printing a part, we never have a constant temperature on our part:
