Dosimetric characterization of 3D printed bolus at different infill percentage for external photon beam radiotherapy

•High infill percentage corresponds to high density and high homogeneity within bolus material.•Modelling bolus as a homogeneous material is satisfying for infill percentages >20%.•Measured dose profile with PLA boluses are more comparable to the TPS calculated profiles.•Discrepancies between cal...
