Abstract

A method of manufacturing a three-dimensional lens comprises inputting a lens template into a controller, depositing a first layer of lens material onto a work surface according to the lens Template, and successively depositing additional filamentous layers of the lens material onto the first layer. The deposition of layers of lens material is done according to the lens template in order to build the three-dimensional lens with a particular transmission scattering profile for transmitted light.

First claim

What is claimed is:

1. A method of manufacturing a three-dimensional lens for a luminary using an additive manufacturing process, the method comprising:
inputting a lens template into a controller of a printer;
depositing a first filamentous layer of transparent polyamide material onto a work surface according to the lens template; and
successively depositing additional filamentous layers of the transparent polyamide material onto the first filamentous layer according to the lens template to build the three-dimensional lens
wherein the lens template stipulates a nozzle diameter and a raster angle of the printer to achieve a transmission scattering profile for transmitted light.

2. The method of claim 1 , further comprising at least one post-printing process.

3. The method of claim 1 , wherein one or more fillers are added to the transparent polyamide material in order to control softness of the transmitted light.

4. The method of claim 3 , wherein the transparent polyamide material is tinted a color.

5. The method of claim 1 , wherein the three-dimensional lens comprises one or more smooth surfaces.

6. The method of claim 1 , wherein at least a portion of the three-dimensional lens is built on a support material, and wherein the support material is removed after the depositing is completed.

7. The method of claim 1 , wherein the first filamentous layer and the additional filamentous layers are substantially parallel to each other.

8. A method of manufacturing a three-dimensional lens, the method comprising:
inputting a lens template into a controller of a printer;
depositing a first layer of lens material onto a work surface according to the lens template; and
successively depositing additional layers of the lens material onto the first layer according to the lens template to build the three-dimensional lens, wherein a transmission scattering profile for transmitted light is part of the lens template, and wherein the lens template stipulates a nozzle diameter and a raster angle of the printer to achieve the transmission scattering profile.

9. The method of claim 8 , wherein the lens is for a luminary.

10. The method of claim 8 , wherein the lens material is a transparent polyamide material.

11. The method of claim 10 , wherein one or more fillers are added to the transparent polyamide material in order to control softness of the transmitted light.

12. The method of claim 11 , wherein the transparent polyamide material is tinted a color.

13. The method of claim 8 , further comprising at least one post-printing process.

14. The method of claim 8 , wherein at least a portion of the three-dimensional lens is built on a support material, and wherein the support material is removed after the depositing of the lens material is completed.

15. The method of claim 8 , wherein the first layer and the additional layers are substantially parallel to each other.
