INCREASED INTERLAYER ADHESION OF THREE-DIMENSIONAL PRINTED ARTICLES

Technologies are generally described to increase interlayer adhesion of a 3D printed article. A printhead of a 3D printing system may include an extrusion nozzle configured to deposit one or more polymer layers onto a substrate to form the 3D printed article. A microplasma source may be coupled to t...

Zusammenfassung:	Technologies are generally described to increase interlayer adhesion of a 3D printed article. A printhead of a 3D printing system may include an extrusion nozzle configured to deposit one or more polymer layers onto a substrate to form the 3D printed article. A microplasma source may be coupled to the extrusion nozzle and may be configured to treat a surface of the substrate or a surface of the deposited polymer layers with plasma from the microplasma. The plasma may include at least one reactive species that may oxidize the surface of the substrate or the surface of the deposited polymer layer upon treatment in order to increase the interlayer adhesion of the 3D printed article.
