Within all 3D printing processes that exist we chose as the first technology that is known as DLP (Digital Light Processing or Digital Light Processing). Basically it works as follows: A Cuba with a liquid polymer is exposed to light of a projector, and where the projector illuminates the liquid hardens.
But … what is that liquid that hardens light? How does that happen? My experience in dealing with this issue tells me to understand this we must go to the foundation, then see how the polymers are from the chemical point of view.
