Abstract
A method includes applying thermal and/or strain modeling to the CAD representation of an object. In addition, scan path data is generated based at least in part on a result of the thermal and/or strain modeling. A build file comprising the scan path data is generated. The build file comprises instructions that configure an additive manufacturing tool to generate the object according to the scan path data.
Claims14
A method comprising:
- obtaining a CAD (computer-aided design) representation of an object;
- applying thermal and/or strain modeling to the CAD representation;
- generating scan path data based at least in part on a result of the thermal and/or strain modeling;
- and
- generating a build file comprising the scan path data, wherein the build file comprises instructions that configure an additive manufacturing tool to generate the object according to the scan path data;
- wherein the scan path data includes a plurality of layer scan path data sets, each of the layer scan path data sets for controlling the additive manufacturing tool to form a respective layer of the object;
- the method further comprising:
- determining respective thicknesses of at least some of said layers of the object based at least in part on a result of said thermal and/or strain modeling, said thicknesses not being identical for all of said layers.
