| Abstract Scope |
Incorporating thermoplastic materials with shape memory properties into the fused filament fabrication process enables what is commonly referred to as 4D printing. When the blends are composed of one or more materials with inherent shape memory properties, the tailoring of critical parameters such as shape recovery temperature can be realized. Previous work by our group demonstrated the creation of shape memory polymer blends where one component was elastomeric. The following work entails the development and characterization of rigid polyester blends that are biocompatible and biodegradable in addition to having shape memory properties. Dynamic mechanical analysis (DMA) was used to determine the critical deformation and recovery temperatures. The effect of print raster patterns on the DMA results was also evaluated Micro-tensile testing was used to characterize the physical properties of the materials at elevated temperatures. Finally, scanning electron microanalysis was used to examine the fracture surfaces of spent tensile specimens. |
