Abstract With the expanding use of polymers in additive manufacturing, sustainable resins for vat photopolymerization are required to reduce their environmental impact. One promising approach achieve this is incorporate biobased fillers that replace acrylates photopolymer as ‘green’ alternatives. In study, composites consisting a methacrylate resin with varying calcium carbonate powder content between 0 and 50 wt.% were investigated. A digital light processing technique was used fabricate tensile test specimens mechanical testing. Good printability, dimensional accuracy, good interlayer adhesion observed composite formulations incorporated up wt.%. Green parts subsequently washed exposed ultraviolet radiation at various post-cure temperatures 20 80 °C. Specimens tested on an Instron universal testing machine evaluate stress–strain characteristics, which included Young’s modulus, ultimate strength, yield strength 0.2% offset, resilience, toughness, percent elongation break. Elevated higher demonstrated modulus values, reaching 4297 MPa post-cured temperature °C, indicating increased stiffness resistance elastic deformation under load compositions filler content.
