All resins showed excellent printability (Figure ), and we further used them to print cylindrical specimens for compression tests. The compression properties displayed similar trends in MW-modulus relationship compared to the tensile test results, and no substantial difference was observed between the BAPO-PEG and BAPO/NVP systems (Figure ). The compression modulus reached 80 MPa with the PEGDMA 6k, while the value for PEGDMA 2k was only about 10 MPa (Figure ). Similarly to the tensile test results, the 3D printed product from PEG 700 was brittle and much weaker than the high MW polymer networks.
