There is an unmet need for a consistent set of tools for the evaluation of 
3D-printed constructs. A toolbox developed to design, characterize, and evaluate 
3D-printed poly(propylene fumarate) scaffolds is proposed for vascularized 
engineered tissues. This toolbox combines modular design and non-destructive 
fabricated design evaluation, evaluates biocompatibility and mechanical 
properties, and models angiogenesis.
