Abstract

A method of making deflection members is disclosed. The deflection members may be 3D objects that may include cross-linkable polymers and may be printed directly onto permeable materials utilizing at least two different printer settings.

First claim

What is claimed is:

1. A method for three-dimensional printing a print material that comprises cross-linkable polymer onto a permeable material, comprising:
printing an under structure that has at least one layer of the print material for a three-dimensional pattern onto a print plate of a three-dimensional printer;
increasing a distance between a print head of the three-dimensional printer and the at least one layer of the print material;
providing a prompt to place the permeable material on the at least one layer of the print material;
printing a bonding layer of the print material for the three-dimensional pattern onto the permeable material at a first printer setting;
printing a build layer of the print material for the three-dimensional pattern onto the bonding layer of the material at a second printer setting, wherein the first printer setting is different from the second printer setting;
curing, via crosslinking, the cross-linkable polymer to form a belt deflection member; and
wherein the first printer setting includes a first material output temperature and the second printer setting includes a second material output temperature, wherein the second material output temperature is different than the first material output temperature.

2. The method of claim 1 , wherein the first printer setting includes a first material flowrate and the second printer setting includes a second material flowrate, wherein the second material flowrate is different than the first material flowrate.

3. The method of claim 1 , wherein portions of the bonding layer of the print material printed directly onto the permeable material flow through holes in the permeable material.

4. The method of claim 1 , wherein the permeable material is a woven fabric.

5. The method of claim 1 , wherein the second material flowrate is at least 5% different than the first material flowrate.

6. The method of claim 1 , wherein the second material output temperature is at least 5 degrees Centigrade lower than the first material output temperature.

7. The method of claim 1 , wherein the permeable material comprises synthetic fibers.

8. The method of claim 3 , wherein the print material bonds with an under structure.

9. The method of claim 4 , wherein the woven fabric comprises woven filaments having a diameter of about 0.20 mm to about 1.2 mm.
