Thermally Assisted Electrohydrodynamic Jet High‐Resolution Printing of High‐Molecular Weight Biopolymer 3D Structures

Abstract: High‐molecular biodegradable and bioresorbable polymers are widely used in tissue engineering applications. In this work, a high‐resolution 3D printing technique, thermally assisted electrohydrodynamic jet (TAEJ) printing, is developed for patterning high‐molecular weight biopolymer 3D structures. Boiling point graded polyvinylpyrrolidone (PVP) and PVP/polycaprolactone biopolymer inks are prepared. The resultant effects of electrohydrodynamic force and thermal field are applied on these polymer ink, to form a … Show more

“…The scaffolds must be made porous to ensure cell migration during cultivation, as well as the transport of nutrients and the removal of metabolic products. Various additive technologies are used for forming scaffolds: inkjet printing, [ 94 ] electrohydrodynamic printing, [ 240–242 ] stereolithography, [ 243,244 ] and multiphoton lithography. [ 245–249 ]…”

“…A higher MVTR would cause wound dehydration and generate a scab, while low WVTR may result in wound maceration and inflammation . In this regard, many researchers engineered bilayer wound dressing integrating W&B nanofibrous membranes with hydrophilic material to obtain optimal breathability . Yang et al .…”

“…During the EHD printing process, the solution on the nozzle tip is polarized by applying a high voltage potential, and this leads to an intense electric field around the pendent drop, deforming it into a cone‐like shape (i.e., the Taylor cone) from whose vertex a fine jet is ejected. Previous work demonstrates the compatibility of EHD printing with a wide variety of inks, ranging from quantum dots, OLED, proteins, silver nanoparticles, and many others, and various 2D and 3D high‐resolution structures smaller than 1 µm have been printed.…”
