Tensile Properties of a Hot Melt Adhesive using Material Extrusion Additive Manufacturing

ASTM D638-14 type-V tensile bars of Technomelt PA 6910 were printed with an Ultimaker 3 fused filament fabrication (FFF) printer. FFF is a thermally-driven form of material extrusion additive manufacturing. Print conditions are given in the "Sample Names and Print Conditions" PDF. Technomelt PA 6910 is a semicrystalline flexible thermoplastic polyamide-based hot melt adhesive from Henkel. Filament with a diameter of 2.85 ± 0.06 mm was extruded from strand-cut pellets of Technomelt PA 6910 using a Dr. Collin single screw extruder (COLLIN Lab & Pilot Solutions GmbH).
