Problems solved by technology

Such a process can allow precise deposition to achieve the final three-dimensional shape of the object (e.g., only finishing machining is required); however, the process is slow and requires multiple steps to form the final object, which actually increases the time and cost

Embodiment approach

[0085] Clause 1. A deposition head for additive manufacturing comprising:

[0086] material feeder, which includes:

[0087] depositing a first feed to a first feeder of the growth face; and

[0088] depositing a second feed to a second feeder of the growth face; and

[0089] an electromagnetic energy source directing electromagnetic energy to said growth surface,

[0090] wherein said electromagnetic energy forms a molten pool on said growth surface, and

[0091] Wherein the melting pool includes at least one of a molten first feed and a molten second feed.

[0092] Clause 2. The deposition head of clause 1, further comprising optics to focus the electromagnetic energy.

[0093] Clause 3. The deposition head of clause 2, wherein the optics is linearly movable relative to the source of electromagnetic energy, and linear movement of the optics relative to the source of electromagnetic energy adjusts the size.

[0094] Clause 4. The deposition head of Clause 2, wherein the...

Abstract

The subject of the present invention is a deposition head for additive manufacturing. A deposition head (106) for additive manufacturing may include a material feeder (110) and an electromagnetic energy source (112) that directs electromagnetic energy (114) to a growth surface (120), the material feeder (110 ) includes a first feeder (134) that deposits a first feed (140) onto a growth face (120), and a second feeder (134) that deposits a second feed (142) onto a growth face (120) 136), wherein the electromagnetic energy (114) forms a molten pool (124) on the growth surface (120), and wherein the molten pool (124) may include a molten first feed (146) and a molten second feed (148) ) at least one of.

Description

technical field [0001] The present disclosure relates generally to additive manufacturing, and more specifically, to a deposition head for additive manufacturing capable of depositing structurally distinct and / or compositionally distinct feedstocks. Background technique [0002] Additive manufacturing, or "3D printing," is a manufacturing process in which an additive manufacturing system (eg, a 3D printer) constructs an object based on a three-dimensional model or other digital representation of the three-dimensional object. Additive manufacturing systems construct or print objects by depositing or otherwise shaping component materials in the shape of the object until they are formed. In one common example, successive layers of material representing a cross-section of the object are deposited, and the deposited layers of material are melted or otherwise solidified to build the final object. The final three-dimensional object is sufficiently dense and can include compound sh...
