Abstract

Method of three-dimensionally printing an article onto a surface comprising a composition, the composition comprising: a binder and a mixture. The mixture comprises nanoparticles in at least two groupings of size ranges.

Claims

1. A method of three-dimensionally printing an article, the method comprising:

providing a surface comprising a composition, the composition comprising;

(i) a binder, and

(ii) a mixture of nanoparticles in a range from 80 wt. % to 99.9 wt. %, based on the total weight of the composition, wherein 10 wt. % to 50 wt. % of the nanoparticles have an average particle diameter in a range from 2 nm to 200 nm and 50 wt. % to 90 wt. % of the nanoparticles have an average particle diameter in a range from 60 nm to 400 nm, and wherein the ratio of average particle diameters of nanoparticles having an average particle diameter in the range from 2 nm to 200 nm to average particle diameters of nanoparticles having an average particle diameter in the range from 60 nm to 400 nm is in a range from 1;

1 to 1;

200; and

three-dimensionally printing the article onto the surface.

2. The method of claim 1, wherein the nanoparticles include modified nanoparticles.

3. The method of claim 1, wherein the mixture of nanoparticles is in a range of from 85 wt. % to 95 wt. %, based on the total weight of the composition.

4. The method of claim 1, wherein the surface has a haze in range from −

1.0 to 1.0 as determined by the Haze Test.

5. The method of claim 1, wherein the article has an accuracy rating of not greater than 1 as determined by the 3-D Printing Accuracy Test.

6. The method of claim 1, wherein the surface has a less than 100 degree of water contact angle.

7. The method of claim 1, wherein the surface has a greater than 8 nm of surface roughness as determined by atomic force microscopy.

8. The method of claim 1 further comprising curing reactive resin to provide the binder.

9. The method of claim 1 further comprising curing radical reactive acrylate to provide the binder.

10. The method of claim 1 further comprising curing a mixture comprising in a range from 80 wt. % to 90 wt. % radical reactive acrylate and 20 wt. % to 10 wt. % of non-radical reactive acrylate, based on the total weight of the mixture, to provide the binder.

11. The method of claim 7, wherein the curing includes actinic radiation.

12. The method of claim 1 further comprising plasma treating the surface prior to three-dimensionally printing the article onto the surface.
