Adhesion of standard filament materials to different build platforms in material extrusion additive manufacturing
Abstract
MaterialextrusionorFusedFilamentFabrication(FFF)isacommonadditive <br/>manufacturingtechnology,whereafilamentismoltenanddepositedonthebuild <br/>surface according to a CAD-defined contour. After each layer the build platform moves <br/>one layer height down, so that the next layer can be deposited. A decent amount of <br/>studies has been investigated on the strength of the interlayer cohesion. However, nearly <br/>no study has dealt with the adhesion of this first deposited layer on the build platform, <br/>although it is a very critical step, as the print cannot be finished in a proper way, if the <br/>part detaches during the print. The present work aims at understanding and optimising <br/>the adhesion of different filaments (poly(lactic acid) and acrylonitrile butadiene styrene) <br/>on two commercially available build platform materials(glass and polyimide). The <br/>adhesion forces are measured by means of a self-constructed adhesion force testing <br/>device, in which printed strands are sheared-off and the maximum adhesion force is <br/>recorded, as a function of the build platform temperature. Additionally, contact angle <br/>measurements and investigations of the surfaces of the sheared-off strands complement <br/>the results. It was found that best adhesion is given, when the temperature of the build <br/>platform is slightly higher than the glass transition temperature of the deposited polymer. <br/>Furthermore, the investigations show that solely the surface tension and topography of <br/>thecontactpartnersarenotsufficienttofullydescribethecomplexadhesion <br/>mechanism in FFF. Especially for the development of novel materials, the knowledge <br/>gained in this work is essential to improve the reliability or optimise the printing process.
