Abstract

A method for forming an object includes rotating a first object forming device about a rotational axis at a first speed to apply a first force to the first object forming device. The first object forming device includes an additive manufacturing device.

First claim

What is claimed is:

1. A method for forming an object, the method comprising:
rotating a first object forming device and a second object forming device about a rotational axis in a circular path at a first speed to apply a first force to the first object forming device and the second object forming device, the first object forming device and the second object forming device are connected to opposing sides of a rotating shaft by arms, the second object forming device counterbalances the first object forming device, and the rotating shaft is arranged substantially concentrically to the axis of rotation and rotates together with the first object forming device and the second object forming device;
wherein each of the first object forming device and the second object forming device comprises an additive manufacturing device comprising a printing head and a printing surface enclosed within a casing; and
wherein the first object forming device and the second object forming device are further enclosed within a housing.

2. The method of claim 1 , further comprising rotating the first object forming device about the rotational axis at a second speed to apply a second force to the first object forming device, the second force is dissimilar from the first force.

3. The method of claim 1 , wherein the first force includes a centrifugal force.

4. The method of claim 1 , wherein the first force is substantially perpendicular to the rotational axis.

5. The method of claim 1 , wherein the first object forming device comprises a fused deposition modeling printer, a stereolithography printer, a digital light processing printer, a selective laser sintering melting printer, an electron beam melting printer, a laminated object manufacturing printer, a binder jetting printer, or a rapid liquid printer.

6. A method for forming an object, the method comprising:
depositing a first layer of material by a first object forming device while rotating the first object forming device and a second object forming device about a rotational axis in a circular path at a first rotational speed to apply a centrifugal force to the first layer of material, resulting in the first layer of material having a first thickness, the first object forming device and the second object forming device are connected to opposing sides of a rotating shaft by arms, the second object forming device counterbalances the first object forming device, and the rotating shaft is arranged substantially concentrically to the axis of rotation and rotates together with the first object forming device and the second object forming device;
wherein each of the first object forming device and the second object forming device comprises an additive manufacturing device comprising a printing head and a printing surface enclosed within a casing; and
wherein the first object forming device and the second object forming device are further enclosed within a housing.

7. The method for forming the object of claim 6 , further comprising depositing a second layer of material by the first object forming device while rotating the first object forming device about the rotational axis at a second rotational speed to apply a second force to the second layer of material, resulting in the second layer of material having a second thickness.

8. The method of claim 7 , wherein the second force is dissimilar from the first force, and the second thickness is dissimilar from the first thickness.

9. The method of claim 1 , wherein the printing surface of the first object forming device is arranged on an outside boundary of the circular path.

10. The method of claim 9 , wherein the printing surface of the first object forming device is arranged perpendicular to the first force.
