Abstract

Origami-based engineering creates products that solve problems inherent in other designs. For example, they can compress into smaller volumes, achieve new and unique motions, and lessen or mitigate numbers of welds, fasteners, or other joining methods. However, a weakness of these designs is the necessity of folding them and seams that result from that folding. If viable, 3D printing these designs would eliminate the need for complicated folding machinery or adhesives to close the seams. Since origami is, by its nature, dynamic, this research aims to help designers predict fatigue lives (number of cycles until failure) of thin, printed PLA walls for origami designs.
