Abstract

A method includes placing a first part proximate a second part, disposing a sintering material in contact with both the first part and the second part, and applying energy to the sintering material to join the first part and the second part. An apparatus includes a first part, a second part, and an additively manufactured joint comprising a sintering material that joins the first part and the second part.

Claims (25)

1. A method, comprising:

placing a first part proximate a second part;

disposing a sintering material in contact with both the first part and the second part;

applying energy to the sintering material; and

joining the first part and the second part, wherein disposing the sintering material and applying energy are repeated to create successive layers of sintered material.

2. The method of claim 1 , wherein the sintering material includes titania-silica powder.

3. The method of claim 1 , wherein the sintering material includes titania-silica suspension.

4. The method of claim 1 , wherein the first part and second part are made of glass.

5. The method of claim 4 , wherein the first part and the second part are made of titania-silica glass.

6. The method of claim 1 , wherein applying energy to the sintering material includes laser sintering the sintering material.

7. A method, comprising:

placing a first part proximate a second part;

disposing a sintering material in contact with both the first part and the second part;

applying energy to the sintering material; and

joining the first part and the second part, wherein the sintering material includes titania-silica powder.

8. A method, comprising:

placing a first part proximate a second part;

disposing a sintering material in contact with both the first part and the second part;

applying energy to the sintering material; and

joining the first part and the second part, wherein the sintering material includes titania-silica suspension.

9. A method, comprising:

placing a first part proximate a second part;

disposing a sintering material in contact with both the first part and the second part;

applying energy to the sintering material; and

joining the first part and the second part, wherein the first part and second part are made of glass, wherein the first part and the second part are made of titania-silica glass.
