Abstract
A method for thermal compensation during an additive manufacturing process. In some aspects, the method may include receiving, at a CNC machine, information relating to a material used in the additive manufacturing process, wherein the received information includes at least a Coefficient for Thermal Expansion (CTE) for the material. The method may further include modifying a distance of travel for a first pre-programmed tool path based on at least the Coefficient for Thermal Expansion (CTE).

A method for thermal compensation during an additive manufacturing process, the method comprising:
- receiving, at a CNC machine, information relating to a material used in the additive manufacturing process, wherein the received information includes at least a Coefficient for Thermal Expansion (CTE) for the material;
- and
- modifying a distance of travel for a first pre-programmed tool path based on at least the Coefficient for Thermal Expansion (CTE);
- wherein the CNC machine includes at least one servomotor for linearly translating a nozzle along the first pre-programmed tool path;
- wherein rotational motion of the servomotor is configured to linearly translate the nozzle via a gearing mechanism;
- and
- wherein modifying the distance of travel for the first pre-programmed tool path includes adjusting the gearing mechanism.
A method for thermal compensation during an additive manufacturing process, the method comprising:
- receiving, at a CNC machine, information relating to a material used in the additive manufacturing process, wherein the received information includes at least a Coefficient for Thermal Expansion (CTE) for the material;
- and
- adjusting a motion of the CNC machine based on at least the CTE of the material;
- wherein adjusting the motion of the CNC machine includes adjusting a gearing mechanism associated with a servomotor of the CNC machine.
A method for thermal compensation during an additive manufacturing process, the method comprising:
- receiving, at a CNC machine, information relating to a material used in the additive manufacturing process, wherein the received information includes at least a Coefficient for Thermal Expansion (CTE) for the material and a temperature of the environment surrounding the CNC machine;
- modifying a motion of a nozzle of the CNC machine based on at least the CTE of the material and the temperature of the environment surrounding the CNC machine;
- wherein the CNC machine includes at least one servomotor configured to linearly translate the nozzle to produce the motion;
- wherein rotational motion of the servomotor is configured to linearly translate the nozzle via a gearing mechanism;
- and
- wherein modifying the motion of the nozzle includes adjusting the gearing mechanism.
