| Abstract Scope |
Employing polymer additive manufacturing for rapid prototyping and fabrication has resulted in huge advantages for short project timelines. Printing large structures is more challenging than small parts due to their long print times and increased material use. This leads to fabricating a mostly hollow structure using infill percentages <10%. These low infill parts can be great in applications such as molding, where minimal strength is required, but can be concerning if the structure is expected to carry load. Ideally, these structures could be tested and modeled, nullifying the “rapid” advantage. To circumvent this, large structures were built with a low percentage gyroid infill and backfilled with a strong and light epoxy-based syntactic foam material. Parts were mechanically tested to determine strength and mode of failure. The mechanical property, time to completion, and cost trade space for low infill parts, solid infill parts, and syntactic foam filled parts is discussed. |
