Abstract
A method for creating an object by consolidating a powder includes providing a composite including a first material arrange to form a porous structure and a second, sacrificial, material surrounding the first material. The composite may be surrounded with a powder and an intermediate objecting may be formed having a dense part bonded to the composite by densifying and bonding the powder to the composite in a single process. The second material may be removed from the intermediate object to from the object, which may include the porous structure and the dense part bonded to the porous structure.

A method for creating an object by consolidating a powder including the following steps:
- a) providing a composite including a first material arranged to form a porous structure and a second, sacrificial, material surrounding the first material;
- b) surrounding the composite with a powder;
- c) forming an intermediate object having a dense part bonded to the composite by densifying and bonding the powder to the composite in a single process;
- and
- d) removing the second material from the intermediate object to form the object, wherein the object includes the porous structure and the dense part bonded to the porous structure.
A method for creating a composite object including a structure including the following steps:
- a) providing the structure by interconnecting or forming a first material;
- b) embedding the structure with a second, sacrificial, material so that the second material surrounds the structure;
- c) surrounding a portion of the structure with a powder or an object;
- d) forming an intermediate object by applying heat and/or pressure so that the portion of the structure is bonded to the densified powder or the object in a single process;
- and
- e) removing the second material from the intermediate object to form the composite object, wherein the composite object includes the structure and densified powder or object bonded to the structure.
