چکیده
Photopolymer composites filled with cellulose nanocrystal (CNC) and/or inorganic nanofillers were fabricated by using digital light processing (DLP) 3D printing. To investigate the effects of different CNC lyophilization concentrations and behaviors particles in photopolymer composites, morphological mechanical properties analyzed. loading levels affected composites. Better dispersion was seen at a lower concentration, highest strength observed 0.25 wt% CNC-filled composite. Furthermore, nano-precipitated calcium carbonate (nano-PCC) nanoclay added to photocurable resins, then effect on evaluated. By analyzing properties, stress transfer mechanism nano-PCC identified related models presented. These supported improved CNC, nano-PCC, nanoclay. This study suggested new approach wood-derived nanomaterials as effective fillers for DLP
