Damage Behavior in Additive Manufacturing based on Infill Pattern and Density with Carbon Particle Filled PolyLactic Acid (CF-PLA) Polymer Filaments
摘要
Polymer bulk materials are used in Material EXtrusion (MEX) based 3-D printing. This additive manufacturing method is well established with a so-called slicing step, where the layer-upon-layer construction is prepared as deposited filaments. Relatively long manufacturing time has lead to an innovative infill density commonly exploited by 3-D printer users. The choice of infill pattern and density is justified for weight reduction but the consequences are often discarded or unknown. Herein, we discuss about damage modeling depending on the infill pattern and density by means of an experimental analysis conducted on Carbon particle Filled PolyLactic Acid (CF-PLA) polymer filaments.
