Abstract
A manufacturing method which manufactures articles which have hollow areas inside them which are subject to their own internal vacuum. A 3-D printer can be located inside a vacuum chamber and the article(s) can be 3-D printed, thereby the hollow area inside each such article is subject to its own vacuum. When removed from the vacuum chamber, the article's hollow area remains subject to its own internal vacuum.
Claims20
A method, comprising:
- providing a 3-D printer in a vacuum chamber;
- causing a vacuum state to be formed inside the vacuum chamber;
- causing the 3-D printer to print an article while the vacuum state is maintained inside the vacuum chamber;
- and
- removing the article.

A method, comprising:
- providing a 3-D printer in a vacuum chamber;
- causing the 3-D printer to print an article on the 3-D printer which is complete but for a hole on the article;
- causing a vacuum state to be formed inside the vacuum chamber;
- and
- causing the 3-D printer to fill in the hole in the article.

A method of printing an object, comprising:
- providing a 3-D printer in a vacuum chamber;
- causing the 3-D printer to print a first layer of the object comprising a plurality of first hollow objects with a plurality of respective first holes, each of the first holes being located in a respective first hollow object;
- causing a vacuum state to be formed inside the vacuum chamber;
- causing the 3-D printer to fill in the plurality of first holes;
- deactivating the vacuum state inside the vacuum chamber;
- causing the 3-D printer to print a second layer of the object comprising a plurality of second hollow objects with a plurality of respective second holes, each of the second holes being located in a respective second hollow object, the second layer being adjacent and attached to the first layer;
- causing a vacuum state to be formed inside the vacuum chamber;
- and
- causing the 3-D printer to fill in the plurality of second holes.
