Fused Deposition modelling creates 3D geometries in various shapes. Using FDM, it is possible not only to print on even surfaces; it is possible to print onto uneven substrates like textiles. The work at hand investigates the penetration of polymer into textiles. Whereby, the resulting geometry of the polymer within and on top of the textile is studied. The textile (woven textiles) is modelled at meso-scale (yarn-level). The G-code for the FDM machine is parsed, analysed and converted by means of a self-implemented Python algorithm. The trajectory of the nozzle is used to calculate and, subsequently, simulate the areas where the polymer gets in contact with the textile. The shape of the resulting polymer structure is meshed and can be utilized for analysis of the penetration behaviour of the polymer into the textile.
