Abstract
This disclosure relates in general to three dimensional (“3D”) printers having a configuration that prepares a three-dimensional object by using a feedstock comprising a metal or a polymer compound and a carbon coating formed on a surface of the compound. This disclosure also relates to such feedstocks and their preparation methods. This disclosure further relates to 3D composite objects prepared by using such printers and feedstocks. This disclosure also relates to carbon containing photocurable formulations and methods for their preparation. This disclosure further relates to electrically conducting 3D polymer composites prepared by using such carbon containing photocurable formulations.
Claims33
A method of preparing a three-dimensional composite object using a three dimensional (“3D”) printer comprising:
- dispensing a feedstock;
- depositing a layer of the feedstock on a surface;
- delivering an electromagnetic radiation to selected areas of the feedstock layer;
- and
- preparing a three-dimensional composite object;
- wherein the feedstock comprises a metal compound and a coating formed on a surface of the metal compound;
- wherein the coating comprises nanocarbons including carbon nanotubes;
- wherein the G/D ratio of the nanocarbons in the coating is approximately the same or higher than the G/D ratio of the nanocarbons in their initial state;
- wherein the coating has a thickness;
- and
- wherein the coating absorbs the delivered electromagnetic radiation at the selected areas of the feedstock layer, converts the absorbed electromagnetic radiation to heat, and transfers the heat to the metal compound, thereby heating the selected areas of the feedstock layer and causing the feedstock to bond to each other and the surface on which it is deposited, and thereby forming a bonded feedstock layer.

- delivering an electromagnetic radiation to selected areas of the feedstock layer;
- and
- preparing a three-dimensional composite object;
- wherein the feedstock comprises a metal compound and a coating formed on a surface of the metal compound;
- wherein the coating comprises a dried-slurry dispersion comprising nanocarbons including carbon nanotubes;
- wherein the coating is substantially free of surfactants, functional groups, and dispersing agents;
- wherein the coating has a thickness in the range of 10 nanometers to 100 micrometers when dry;
- and
- wherein the coating absorbs the delivered electromagnetic radiation at the selected areas of the feedstock layer, converts the absorbed electromagnetic radiation to heat, and transfers the heat to the metal compound, thereby heating the selected areas of the feedstock layer and causing the feedstock to bond to each other and the surface on which it is deposited, and thereby forming a bonded feedstock layer.
