Abstract
The present disclosure concerns a digital fabricating method for constructing 3D structures, comprising the following steps: (a) precursor consist of monomers and photo-initiator is introduced into reaction cell; (b) exposing the precursor to the DLP projector for several times to gain an inhomogeneous sheet; (c) swelling the sheet in solvent to gain 3D structure. The disclosure provides a simple and easy way to produce precise 3D structure.
Claims10
A method for constructing 3D polymer structures with digital light patterning technology, comprising the following steps:
- (a) introducing photo-curable precursors comprising monomers and photo-initiators into a flat reaction cell;
- (b) using a DLP-type projector to illuminate and cure the precursor locally and cumulatively, getting a heterogeneous 2D polymer sheet;
- (c) swelling the 2D polymer sheet in a certain solvent or heat the sheet until reaching a equilibrium 3D structure.
