Abstract

A method of adjusting a three-dimensional representation of an object to be manufactured in an additive manufacturing process comprises determining a processing operation to be applied to the object, and adjusting the three-dimensional representation of the object based on adjustment parameters associated with the processing operation.

First claim

1 . A method of adjusting a three-dimensional representation of an object to be manufactured in an additive manufacturing process, the method comprising:
determining a processing operation to be applied to the object; and adjusting the three-dimensional representation of the object based on adjustment parameters associated with the processing operation.

2 . The method of claim 1 , wherein adjusting the three-dimensional representation of the object comprises adjusting the three-dimensional representation to compensate for a change in geometry of the object due to the processing operation to be applied to the object.

3 . The method of claim 1 , wherein adjusting the three-dimensional representation of the object comprises applying a thinning operation to the three-dimensional representation of the object.

4 . The method of claim 1 , wherein adjusting the three-dimensional representation of the object comprises applying a surface texture to a surface of the three-dimensional representation of the object.

5 . The method of claim 1 , wherein the processing operation to be applied to the object comprises an operation to apply a coating, plating, paint or dye to the object.

6 . Apparatus for processing a 3D model, the apparatus comprising:
a processing module to process the 3D model to produce an amended 3D model, wherein the process is based on a treatment to be performed on an object; and a sending module to send the amended 3D model to an additive manufacturing apparatus to create the object from the amended 3D model.

7 . The apparatus of claim 6 , wherein the treatment to be performed on the object modifies a dimension of the first object, and wherein the processing module is to process the 3D model by modifying a dimension of the 3D model to counteract the modification of the dimension.

8 . The apparatus of claim 6 , wherein the processing module is to process the 3D model by eroding a surface of the 3D model based on the treatment to be performed on the object.

9 . The apparatus of claim 6 , wherein the processing module is to process the 3D model by applying a structural modification to the 3D model based on the treatment to be performed on the object.

10 . The apparatus of claim 6 , further comprising receiving the 3D model, and receiving an indication of the treatment to be applied to the object.

11 . A machine-readable medium comprising instructions that, when executed by a processor, cause the processor to:
process a first object description based on a surface modification parameter to produce a second object description, wherein the second object description describes an object and wherein the surface modification parameter is based on a surface modification to be performed on the object following an additive manufacturing procedure to create the object.

12 . The machine-readable medium of claim 11 , further comprising instructions that, when executed by a processor, cause the processor to process the first object description to produce the second object description by altering the first object description to counterbalance an estimated change to a shape of the object due to the surface modification to be performed on the object.

13 . The machine-readable medium of claim 11 , comprising instructions that, when executed by a processor, cause the processor to provide the second object description to an additive manufacturing device to create the object.

14 . The machine-readable medium of claim 11 , comprising instructions that, when executed by a processor, cause the processor to receive a notification of the surface modification to be performed on the object.

15 . The machine-readable medium of claim 11 , comprising instructions that, when executed by a processor, cause the processor to modify a surface property of the first object description based on the surface modification parameter.
