CPC Class B33Y

A composite filament includes a core particle comprising a styrene/acrylate polymer resin, and a shell comprising a styrene/acrylate ionomer resin, wherein the styrene/acrylate ionomer resin comprises a metal ion acrylate monomer, and methods of making thereof. Various articles can be manufactured from such composite filaments.

The invention describes methods for producing a biphasic nanocomposite scaffold comprising custom polymer-based core-shelled nanospheres by the physical and chemical attachment of two disparate polymeric materials whose composition can be readily modified with tissue-specific nanomaterials and products created using such methods. The custom nanospheres are constructed via co-axial wet electrospraying and can be employed to deliver compounds to the polymeric materials.

The present invention relates to an article fabrication system having a plurality of material deposition tools containing one or more materials useful in fabricating the article, and a material deposition device having a tool interface for receiving one of the material deposition tools. A system controller is operably connected to the material deposition device to control operation of the material deposition device. Also disclosed is a method of fabricating an article using the system of the invention and a method of fabricating a living three-dimensional structure.
