Abstract
A composition useful in forming a structure in the form of a substantially interconnected vascular network. The composition includes a powder including a carbohydrate powder and an anti-caking agent, where the powder: has a granular form, and has a specific energy of less than 6 millijoules per milliliter (mJ/mL).
Claims20
A method of forming a substantially interconnected vascular network, comprising:
- solidifying a powder by fusing with an energy beam to form a filament network;
- wherein the filament network comprises a plurality of filaments and defines a void space, and the plurality of filaments is capable of dissolving or degrading in water;
- backfilling the void space of the filament network with a matrix material;
- and
- removing the filaments to form the substantially interconnected vascular network comprising fluidic channels,
- wherein the powder includes a carbohydrate powder and has a granular form and a specific energy (mJ/g) multiplied by the powder's conditioned bulk density (g/mL) of less than 6 millijoules per milliliter (mJ/mL).
3 more elements
A structure comprising a substantially interconnected vascular network, comprising:
- a matrix material through which a structural material is disposed;
- wherein the structural material is capable of dissolving or degrading in water and is formed from a powder that is fused into a solid when irradiated with an energy beam, wherein the powder comprises a carbohydrate powder and has a granular form and a specific energy (mJ/g) multiplied by the powder's conditioned bulk density (g/mL) of less than 6 millijoules per milliliter (mJ/mL).
