Abstract
A method of strengthening printed components created by a three-dimensional printing technique utilizes cynoacrylate adhesives. The component is first printed in successive layers of calcium sulfate or similar materials on a three-dimensional printer. The component is next submerged in liquid adhesive contained in a vacuum chamber. A vacuum is applied for a time period to degas the voids and interstices in the material of the component. The vacuum chamber may then be pressurized to transfer liquid adhesive into the evacuated voids. The component is removed from the vacuum chamber and the adhesive allowed to polymerize.
Claims13
A method of increasing the strength of a printed component comprising:
- forming a printed component from successive layers deposited by a three-dimensional printing technique;
- submerging the printed component in a liquid adhesive within a vacuum chamber;
- applying a vacuum to the vacuum chamber to evacuate gasses from voids in the printed component;
- pressurizing the vacuum chamber to transfer liquid adhesive into voids;
- and
- removing the printed component from the vacuum chamber and allowing the liquid adhesive to polymerize in the voids.
