Abstract Scope Additive manufacturing (AM) has shown to provide profound applications in fields of engineering and science by offering design freedom along with versatility in feed-stock material. Polylactic-acid (PLA) is an exceedingly popular biodegradable polymer commonly used in material extrusion printing. As a promising alternative to petroleum based polymers, PLA has found use in several industries due to its bio-compatibility, renew-ability, and good mechanical properties. Several printing parameters in the material extrusion process can alter physical characteristics of a part such as ironing. To date, there is limited information on the effects the ironing process has on 3D printed PLA. This study utilized a fractional factorial design in order to correlate the impact ironing has on the surface morphology and thermo-mechanical properties of 3D printed and ironed PLA. This work reports the surface morphology, surface roughness, and visco-elastic properties, including storage modulus and glass transition temperature, of 3D printed and ironed PLA.
