Integration of soft tooling by additive manufacturing in polymer profile extrusion process chain
Abstract
Integrating additive manufacturing (AM) into polymer extrusion offersprocess chain flexibility and design freedom. It reduces the need fortime-consuming iterations and trial-and-error in the die design process.Consequently, polymer AM of extrusion (i.e., soft tooling) allows for ashorter product development cycle and cost-effectiveness forsmall-scale production and highly customized products. In this study,carbon fibre (CF)-polyether-ether-ketone (PEEK) dies were manufacturedusing the fused filament fabrication (FFF) AM process, employing astreamlined die design achieved through freeform transition planes.Calibration slides were produced using masked stereolithography (MSLA),FFF, and conventional manufacturing techniques (i.e., machining) topreserve the final product’s cross-section during the cooling process.The dimensional and surface characteristics of these calibration slideswere evaluated to assess the dimensional accuracy and surface topographyof various materials and manufacturing processes. The dimensionalevaluation reveals that MSLA-printed parts exhibit deviation from thenominal dimension closer to the conventionally manufactured part. Theintegrated soft tooling in the polymer extrusion line was tested withpolypropylene (PP) and acrylonitrile butadiene styrene (ABS) as extrudedmaterials. The surface topography of the CF-PEEK die displaysdistinctive ripple features resulting from the FFF process, identifiedby relatively flat peaks and deep valleys. The overall surface textureparameter values of CF-PEEK were higher due to the presence of deepvalleys. Considering that the areas around the peaks interacted morewith polymer molecules during the extrusion, the surface textureparameters of the extrudates were closer to the value observed in 90 µmregion areas around the peaks. Notably, extrudates of AM calibrationslides have lower surface texture parameters than extrudates ofconventionally manufactured calibration slides, even though surfacedefects in the form of dimple sink marks were observed in extrudedmaterial of PP from extrudates using AM calibration slides.
