Examining the Relationship between Forces During Stereolithography 3D Printing and Geometric Parameters of the Model

MATEC Web of Conferences, 2016
In the case of stereolithography 3D printing technology, detaching formed model from the tank with photopolymer is a lengthy process. Forces, which appear during removing of solid photopolymer layerformed in stereolithography 3D DLP printer, can destroy ...

MODELING OF PHOTOPOLYMER CURING

PNRPU Mechanics Bulletin
The paper considers the process of curing a photopolymer material. The effect of light on a photopolymer material triggers a reaction that leads to the conversion of polymer chains, which leads to the release of heat and an increase of temperature, solidification or an increase of stiffness of the material, and is also accompanied by a volumetric ...
