Abstract
A fabrication process includes: 1) forming an object by 3D printing; 2) smoothing the object by applying a gel to the object to coat at least a portion of the object with a film of the gel; 3) subjecting the object coated with the film to vacuum; and 4) curing the film to yield the object coated with the cured film.
Claims20
A fabrication process comprising:
- forming an object by 3D printing having a first rms surface roughness;
- smoothing the object by applying a gel to the object to coat at least a portion of the object with a film of the gel;
- subjecting the object coated with the film to vacuum;
- and
- curing the film to yield the object coated with the cured film,
- wherein the cured film has a second root mean square (rms) surface roughness that is 100 nm or less and wherein the first rms surface roughness is at least 10 times greater than the rms surface roughness of the cured film.
3 more elements
An optical device comprising:
- an object;
- and
- a polymer film coating the object and having a root mean square (rms) surface roughness of 100 nm or less,
- wherein the object is an object having a rms surface roughness of at least 10 times greater than the rms surface roughness of the polymer film and
- wherein the optical device comprises a reflective lens, a refractive lens, an optically smooth mirrored surface, or a combination thereof.
