Journal ArticleDOI
Three-Dimensional (3D) Printing of Polymer-Metal Hybrid Materials by Fused Deposition Modeling.
TL;DR: Investigations show that while FDM printing allows for producing objects with mechanical properties similar to the original materials, metal-polymer blends cannot be used for the rapid manufacturing of objects necessitating mechanical strength.
Journal ArticleDOI
Increasing adhesion of 3D printing on textile fabrics by polymer coating
Lena Unger,Marvin Scheideler,Pia Meyer,Julia Harland,Andreas Gorzen,Martin Wortmann,Axel Dreyer,Andrea Ehrmann +7 more
TL;DR: In this article, a method to improve the adhesion of a 3D printed object on a textile fabric by previously coating the latter with a polymer layer was proposed, without changing the bending stiffness and haptic properties of a fabric.
Journal ArticleDOI
Electrospinning on 3D Printed Polymers for Mechanically Stabilized Filter Composites.
TL;DR: Although the adhesion between both materials is insufficient in the case of a common rigid printing polymer, nanofiber mats show strong adhesion to 3D printed scaffolds from thermoplastic polyurethane (TPU), paves the way to a second approach of combining 3D printing and electrospinning in order to prepare mechanically stable filters with a nanofibrous surface.
Journal ArticleDOI
New Polymers for Needleless Electrospinning from Low-Toxic Solvents.
Martin Wortmann,Natalie Frese,Lilia Sabantina,Richard Petkau,Franziska Kinzel,Armin Gölzhäuser,Elmar Moritzer,Bruno Hüsgen,Andrea Ehrmann +8 more
TL;DR: A series of new polymers that are applicable for electrospinning from DMSO, including poly(vinyl alcohol-co-ethylene) (EVOH), and acrylonitrile butadiene styrene (ABS) as water-insoluble polymers were found to be suitable for the production of nanofibers.
Journal ArticleDOI
Stabilization of polyacrylonitrile nanofiber mats obtained by needleless electrospinning using dimethyl sulfoxide as solvent
Lilia Sabantina,Lilia Sabantina,Michaela Klöcker,Martin Wortmann,José Rodríguez Mirasol,Tomás Cordero,Elmar Moritzer,Karin Finsterbusch,Andrea Ehrmann +8 more
TL;DR: In this article, the authors used polyacrylonitrile as a base material for thermochemical conversion into carbon nanofibers, and especially nanofiber mats, produced by electrospinning, are of interest to create carbon nanoribers.
