Numerical and experimental evaluation of SLA polymers adhesion for innovative bio-MEMS

Polymer stereolithography is well known additive process already used in bio-MEMS and labs-on-chip applications. The same polymerization process is used in this paper to replace traditional adhesives and to provide fast, reliable and transparent joint with different materials as PMMA in microfluidic devices. The properties of adhesion between resin and transparent covering layers are characterized with mechanical peeling tests which are also used to validate numerical models based on cohesive approach. The influence of process parameters on mechanical properties of the joint are also analyzed. (C) 2018 The Author(s). Published by Elsevier Ltd.
