How to print core sheath filaments and adhesives

摘要

The present disclosure provides a core sheath filament.The core sheath filament comprises an adhesive core and a non cohesive sheath, and the sheath shows a melt flow index of less than 15 grams per 10 minutes.The present disclosure also provides a method of printing an adhesive.The method includes: a) melting the core sheath filament in the nozzle to form a melt composition and (b) distributing the melt composition onto the substrate through the nozzle.Steps a and B are performed one or more times to form the printed adhesive.The core sheath filament comprises an adhesive core and a non adhesive sheath.In addition, a manufacturing device having one or more processors receives a digital object containing data defining the article and using a manufacturing device, using a core sheath filament by an additional manufacturing process, based on a digital object A method is provided including generating a printed adhesive.One or more processors, which use a core sheath filament to create a physical object of an article containing a printed adhesive on a 3D printer, according to a display that displays a 3D model of the article and a 3D model selected by the user; Systems are also provided.
