Abstract
Additive manufacturing systems and methods are provided. An additive manufacturing system includes a build volume; a powder disposed in the build volume, the powder occupying at least a portion of the build volume and having an outer boundary; a beam generator configured to generate a beam to irradiate the powder; and a ram defining a passthrough configured to transmit the beam to an irradiation location disposed within the outer boundary of the powder.
Claims20
An additive manufacturing system comprising:
- a build volume;
- a powder disposed in the build volume, the powder occupying at least a portion of the build volume and having an outer boundary;
- a beam generator configured to generate a beam to irradiate the powder;
- a ram insertable into the powder, the ram defining a ram tip and a passthrough that transmits the beam to an irradiation location disposed within the outer boundary of the powder to irradiate powder spaced apart from the outer boundary of the powder;
- and
- a removable cover that covers the ram tip while the ram is inserted into the powder, the removable cover being removed from the ram tip after the ram is inserted into the powder to allow transmission of the beam to the irradiation location.

A method of additive manufacturing, the method comprising:
- providing a powder in a build volume of an additive manufacturing system, the powder having an outer boundary, and the additive manufacturing system comprising a beam generator configured to generate an irradiating beam that transmits through a passthrough of a ram to irradiate the powder;
- inserting the ram into the powder;
- and
- removing a removable cover that covers a ram tip of the ram while the ram is inserted into the powder, the removable cover being removable from the ram such that the irradiating beam is transmitted through an opening in the ram tip to irradiate the powder at an irradiation location disposed within an outer boundary of the powder.
