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 a nanocarbon including a carbon nanotube;
- wherein the coating has a thickness;
- and
- wherein the coating absorbs the delivered electromagnetic radiation at a selected area of the feedstock layer, converts the absorbed electromagnetic radiation to heat, and transfers the heat to the metal compound, thereby heating the selected area 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.
A method of preparing a three-dimensional composite object using a three dimensional (“3D”) printer, comprising:
- dispensing a feedstock comprising a metal compound and a coating thereon;
- depositing a layer of the feedstock on a surface;
- and
- delivering electromagnetic radiation to selected areas of the feedstock layer such that the feedstock and the material of the surface on which it is deposited bond together;
- wherein the feedstock is prepared by:
- dispersing nanocarbons including carbon nanotubes in a solvent to form a slurry without any surfactants, dispersing agents or functional groups, applying the slurry to one or more surfaces of a metal compound, and
- allowing the slurry to dry and form a coating on the one or more surfaces of the metal compound;
- wherein the amount of the slurry applied to the metal compound is sufficient to result in a dried coating having a thickness in the range of 10 nanometers to 100 micrometers.
