From small to large scale – Pharma-grade filament manufacturing & thermal analysis of the printing process – Presented by Julian Quodbach, HHU

From small scale to large scale – Pharma-grade filament manufacturing and thermal analysis of the printing process – Presented by Julian Quodbach, Heinrich Heine University Düsseldorf at The 3D Medicine & Pharmaceutical Printing Conference which will take place on  Feb 01, 2017 at MECC Maastricht in The Netherlands.

Pharmaceutical fused deposition modeling requires feedstock material based on pharma-grade polymers. In literature, either non-pharma-grade polymers are chosen due to their easy processability and/or small-scale extruders were used for filament production that cannot produce substantial amounts of feedstock material. In this presentation, large scale fabrication of Eudragit RL based, drug loaded filaments with a continuously running twin-screw-extruder is presented. The mechanical properties of these filaments are compared to commercial specimen. In a second part, a thermal imaging analysis of the printing process is shown. It is demonstrated that the thermal load is significantly lower than process settings suggest.
