Tetrahydrofurfuryl methacrylate (THFMA) is derived from renewable resources and is obtained by chemical modification of furfural produced from hemicellulose. THFMA was used as a biobased reactive diluent that reduces the viscosity of AESO in DLP 3D printing. According to stress relaxation tests, THFMA was found to be a suitable monomer in the UV-curing of HPPA and AESO because the formed dynamic networks could rapidly undergo thermoactivated network topology rearrangements. The addition of THFMA to the resins contributed to weldability, repairability, shape memory, and reprocessability properties[2].
