Abstract Scope Biocompatible stimuli-responsive materials are extensively utilized in tissue engineering and drug delivery systems. The objective of this study is to characterize rheological properties of UV photocurable resin for vat photopolymerization additive manufacturing of porous 4D biocompatible multi-materials, that change their properties as function of time when exposed to certain stimuli. The system contains Soybean Oil Epoxidized Acrylate, Polyethylene Glycol Diacrylate, and different amounts of titanium dioxide or titanium precursor. Results show that, without any ceramic phase, the viscosity levels were in the range of 3.5 - 1.5 Pa.s, while highly loaded resin with TiO2 solid content of 5.0 – 0.5 wt% reveals viscosity levels of 4.5 – 0.7 Pa.s. However, the addition of the ceramic precursor up to 2% did not alter the viscosity of the system. This study provided initial insights into determining the rheological processing window to prepare photocurable resin with nanofillers and to create a stimuli-responsive system.
