EVALUATING THE IMPACT OF 2-HEMA AND TMP(15EO)TA ON BIOCOMPATIBLE PHOTOPOLYMER 3D PRINTING MATERIALS

In traditional photopolymer 3D printing materials, most diluent monomers exhibit toxicity, making them unsuitable for biomedical applications.Previous research identified 2-Hydroxyethyl Methacrylate (2-HEMA) as a biocompatible diluent monomer, though its single photopolymerizable functional group results in suboptimal curing performance.Literature suggests that Trimethylolpropane Ethoxylate Triacrylate (TMP(15EO)TA), with its three photopolymerizable functional groups, offers both biocompatibility and enhanced curing.This study investigates the effects of 2-HEMA and TMP(15EO)TA diluent monomers on 3D printing materials.Results indicate that TMP(15EO)TA-containing materials exhibit improved side roughness, aiding in stereolithography, increased viscosity, reduced hardness, and over 80% cell viability, demonstrating good biocompatibility.These findings provide a basis for the development of 3D-printed biomedical materials, which could significantly advance tissue engineering and other medical applications by providing safer and more effective materials.
