👉🏻 In this video, I am fully explaining why 3D prints actually warp. Most people think it is the bed adhesion issue, but that is not the main reason why 3D prints warp. The true reasons are too low chamber temperatures and excessive print cooling. While it sounds simple, this goes way deeper when we compare amorphous and semi-crystalline materials, so make sure to watch the whole video. All the information in this video was based on my experience, testing, and scientific articles.
