Method of three-dimensional printing
A sustainable material suitable for three-dimensional printing is disclosed. The sustainable material comprises a resin derived from a bio-based diacid monomer and a bio-based glycol monomer. The resulting sustainable material provides a much more robust 3-D printing material with different properties than conventional materials.
1. A sustainable three-dimensional printing material comprising:
a filament consisting of:
a sustainable resin derived from a bio-based diacid monomer and bio-based glycol monomer;
wherein when the sustainable resin is polybutylene succinate, the weight average molecular weight of the sustainable resin is from about 10,000 grams/mole to about 500,000 grams/mole; further wherein the polybutylene succinate is produced through the reaction of bio-based succinic acid and 1,4-butane-diol as shown by the reaction scheme below:
wherein n is from about 100 to about 100,000;
a colorant; and
an optional conductive material.
2. The three-dimensional printing material of claim 1 , wherein the sustainable resin is derived from about 45 to about 55 percent by mole equivalent of bio-based diacid monomer, and from about 45 to about 55 percent by mole equivalent of the bio-based glycol monomer, provided that the sum of both is 100 percent.
3. The three-dimensional printing material of claim 1 , wherein the sustainable resin has a softening point of from about 120° C. to about 200° C.
4. The three-dimensional printing material of claim 1 , wherein the sustainable resin has a freezing point of from about 20° C. to about 60° C.
5. The three-dimensional printing material of claim 1 , wherein the sustainable resin has a viscosity of from about 200 centipoise to about 10,000 centipoise at 100° C. to about 200° C.
6. The three-dimensional printing material of claim 1 , wherein the sustainable resin has a melting point of from about 75° C. to about 150° C.
7. The three-dimensional printing material of claim 1 , wherein the sustainable resin is present in the sustainable material in an amount of from about 90% to about 99% by weight.
8. The three-dimensional printing material of claim 1 , wherein the colorant is present in the sustainable material in an amount of from about 1% to about 10% by weight.
9. The three-dimensional printing material of claim 1 having a Young's Modulus of from about 0.5 to about 5 gigapascals, and a Yield Stress of from about 10 to about 100 megapascals.
