Support Edifice for Three-Dimensional Printing

An object prior to sintering prepared by three-dimensional printing comprising:

• (I) a main object body, and
• (II) one or more support edifices,
• (i) wherein said main object body (I) comprises:
• (Ia) one or more mold layers, and
• (Ib) one or more corresponding crafting medium layers,
• wherein each of the one or more mold layers (Ia) substantially contains a corresponding crafting medium layer (Ib) of the main object body;
• and
• (ii) wherein said one or more support edifices (II) comprise
• (IIa) one or more mold layers, and
• (IIb) one or more corresponding crafting medium layers,
• wherein each of the one or more mold layers (IIa) substantially contains a corresponding crafting medium layer (IIb) of the support edifice,
• wherein at least one of the mold layers (IIa) substantially covers one or more contact points of the support edifice with the three-dimensional object,
• wherein each of the one or more mold layers (IIa) for the support edifice (IIb) comprises a structural additive that substantially prevents fusing of the support edifice (II) to the main object body (I) during subsequent sintering of the object.

A method for three-dimensional printing of a support edifice comprising

• (a) depositing a mold layer from a print head,
• (b) depositing a layer of a crafting medium with a print head within the confines of the mold layer,
• (c) depositing a mold layer that substantially covers one or more contact points of the support edifice with the three-dimensional object;
• wherein each of the mold layers comprises a structural additive that substantially prevents fusing of the support edifice to the object during subsequent sintering of the object.

A method for three-dimensional printing of an object comprising a support edifice, comprising:

• (a) depositing a mold layer from a print head to define a mold for the object and the support edifice,
• (b) depositing a layer of a crafting medium with a print head within the confines of the mold layer for the object and the support edifice,
• (c) repeating steps (a) and (b) until the final layer of the crafting medium and mold layer is deposited within the confines of the mold for the object and support edifice wherein the mold layer substantially covers the terminal layer of the crafting medium representing the contact point for the support edifice with the object and now representing a mold layer for the object;
• (d) depositing a further layer of crafting medium within the confines of the mold;
• and
• (e) depositing further layers mold and crafting medium to complete the object.

An object prior to sintering prepared by three-dimensional printing comprising two or more separate subobjects:

• (I) a first subobject, and
• (II) one more additional subobjects,
• (i) wherein said first subobject (I) comprises:
• (Ia) one or more mold layers, and
• (Ib) one or more corresponding crafting medium layers,
• wherein each of the one or more mold layers (Ia) substantially contains a corresponding crafting medium layer (Ib) of the subobject;
• and
• (ii) wherein said one or more additional subobjects (II) comprises
• (IIa) one or more mold layers, and
• (IIb) one or more corresponding crafting medium layers of the additional subobject,
• wherein each of the one or more mold layers (IIa) of the one or more subjects substantially contains a corresponding crafting medium layer (IIb) of the one or more subobjects;
• and
• wherein at least one of the mold layers (Ia) or (IIa) substantially covers one or more proximity points of the subobject (I) or the one or more additional subobjects (II) with each other and the subobject (I),
• wherein each of the one or more mold layers (Ia) or (IIa) comprises a structural additive that substantially prevents fusing of the subobject (I) with the one or more subobjects (II) and with each other during subsequent sintering of the object.

A support edifice for a three-dimensional object printed from a crafting medium, said support edifice comprising:

• (a) one or more mold layers,
• (b) one or more corresponding crafting medium layers,
• wherein each of the one or more mold layers of (a) substantially contains a corresponding crafting medium layer (b) of the support edifice,
• wherein at least one of the mold layers substantially covers one or more contact points of the support edifice with the three-dimensional object, and
• wherein said at least one or more of the mold layers that substantially covers one or more contact points of the support edifice with the three-dimensional object comprises a structural additive that substantially prevents fusing of the crafting medium of the support edifice to the crafting medium of the object during subsequent sintering of the object.
