Abstract
The present invention relates to volumetric additive manufacturing (3D printing) through holograms for manufacturing high performance components with high mechanical properties at low cost and with low environmental impact from a wide variety of different materials, including but not limited to metallic materials, ceramic materials, polymeric materials and/or combinations thereof. The invention further relates to the apparatus used, and to the printed components.
Claims50
A method for the additive manufacturing of components, in particular a method for the volumetric printing of components through holograms, comprising the following steps:
- Step 1:
- providing a powder bed comprising at least one layer of powder;
- Step 2:
- exposing at least part of the powder bed to radiation to consolidate only part of the powder in the powder bed;
- Step 3:
- optionally, providing an additional layer of powder adjacent to the previously consolidated or at least partially consolidated layer of powder to form successive powder layers of the powder bed;
- Step 4:
- optionally, repeating step 2;
- Step 5:
- optionally, repeating steps 3 and 4 until the component is completely additively manufactured;
- and
- Step 6:
- separating the consolidated or partially consolidated powder from the unconsolidated powder in the powder bed.

A method for the additive manufacturing of components, in particular a method for the volumetric printing of components through holograms, comprising the following steps:
- Step 1:
- providing a slurry bed comprising at least one layer of slurry;
- Step 2:
- exposing at least part of the polymer bed to radiation to cure only part of the layer of slurry in the slurry bed;
- Step 3:
- optionally, providing an additional layer of slurry adjacent to the previously cured or at least partially cured layer of slurry to form successive layers of the slurry bed;
- Step 4:
- optionally, repeating step 2;
- Step 5:
- optionally, repeating steps 3 and 4 until the component is completely additively manufactured;
- and
- Step 6:
- separating the cured or partially cured slurry from the uncured slurry in the slurry bed.
(canceled)
An apparatus for the additive manufacturing of components, in particular an apparatus for the volumetric printing of components through holograms, the apparatus comprising:
- a chamber in which a three-dimensional component is additively manufactured;
- a powder holder for holding a powder bed,
- at least one radiation generator;
- and
- at least one radiation applicator per generator.
