Structure–Processing–Property Relationships of 3D Printed Porous Polymeric Materials

Abstract: Imparting porosity to 3D printed polymeric materials is an attractive option for producing lightweight, flexible, customizable objects such as sensors and garments. Although methods currently exist to introduce pores into 3D printed objects, little work has explored the structure–processing–property relationships of these materials. In this study, photopolymer/sacrificial paraffin filler composite inks were produced and printed by a direct ink writing (DIW) technique that leveraged paraffin particles as sacrif… Show more

“…3D printing is a recently developed technology to create materials with predesigned structures, and this strategy is also employed to prepare customized POPs, 220–224 especially printing customized POPs for biomedical applications. Previously, 3D printing technology has been reported to have limitations to fabricate porous polymer structures with pores in the sub-micrometer scale.…”

“…Capsule shell fusion provides a new route to transform a powder into a monolith, which can enable handling of the liquid as a solid and is relevant for integration of liquids into applications that require dry feedstock . Additionally, these dynamic capsules could also find use as feedstocks for producing composites by additive manufacturing (e.g., direct ink writing , ), without the use of high temperature, high pressure, or UV irradiation. Alternatively, shell destruction can be used to release capsule contents.…”

“…The ink is then solidified to form the desired object. 10,11 Particle fillers have previously been demonstrated to impart the necessary rheological properties to Newtonian liquids such as photopolymer resins 12,13 and polymer solutions 14 to prepare DIW inks. In this manner, the selection of polymer liquids and particle filler can be tuned to achieve desired functionality and performance of printed objects.…”
