Limonene dioxide (LDO) was purchased from Symrise (Holzminden, Germany). Epoxidized soybean oil (ESO) and epoxidized linseed oil (ELO) were obtained from Brenntag (Lachine, QC, Canada).
Trimethylolpropane triacrylate (TMPTA), phenylbis(2,4,6-trimethylbenzoyl) phosphine oxide (BAPO),
acrylated epoxidized soybean oil (AESO), bis(4-methylphenyl) iodonium hexafluorophosphate (4-Phenylthiophenyl) diphenylsulfonium triflate (PAG) were purchased from Sigma-Aldrich (Mississauga, ON, Canada) and used as received. Irradiation was realized with a mercury lamp Dymax 2000 (Torringto, CT, USA) flood lamp. The lamp was calibrated with a spectroradiometer and was found to deliver an irradiance of 49 mW/cm
2 centered on the wavelength λ = 300 nm. The 3D printer was a Voxelab Polaris 2K Color LCD Resin 3D Printer (Jinhua City, China) equipped with a 405 nm lamp. It has a nominal resolution of 0.047 mm, and a print speed which can be adjusted between 10 to 50 mm/h.
