Optimizing properties of additively manufactured "biodegradable papertronics" dictates the fine balance of laser settings to maximize the sintering of nanoparticles and minimize damage to substrates. In this study, molecular dynamics is utilized to understand the sintering of silver and copper double-nanoparticles at different temperatures. The effects of nanoparticle size, nanoparticles’ size ratios, misorientation angle (including both twist and tilt), sintering temperature, and material type on the double-nanoparticles’ sintering characteristics such as neck size and center-to-center distances are quantified. Moreover, the evolution of particle shape and defect contents during the sintering process are captured. The changes in neck size in different case studies are compared to and improved upon, existing mathematical models.
