Abstract
A method of forming a component that includes identifying an acute angle in an original model that is a virtual model of the component. The acute angle is defined by a first surface and a second surface. The method includes compensating the original model at the acute angle to create a compensated acute angle in a compensated model. The method also includes forming, by additive manufacturing, the component based upon the compensated model, where the formed component is more alike the original model than the compensated model.
Claims20
A method of forming a physical manifestation of a component, the method comprising:
- prior to manufacturing any physical manifestation of the component, identifying an acute angle in an original model that is a virtual model of the component, the acute angle defined by an intersection of a first surface and a ligament;
- prior to manufacturing the physical manifestation of the component, compensating the original model to create a compensated model, wherein the compensating includes removing a portion of the first surface to form a compensated angle between the first surface and the ligament, wherein the compensated model includes the compensated angle and the compensated angle is smaller than the acute angle;
- and
- manufacturing the physical manifestation of the component by forming, by additive manufacturing, the physical manifestation of the component based upon the compensated model such that the physical manifestation of the component includes a final acute angle that is more alike the identified acute angle in the original model than the compensated angle due to distortions during forming of the physical manifestation of the component.
A method of printing a physical manifestation of a component comprising:
- prior to printing any physical manifestation of the component, receiving an original model of the component at a printer;
- prior to printing the physical manifestation of the component, identifying an acute angle in a geometry of the original model, the acute angle defined by an intersection of a first surface and a ligament;
- prior to printing the physical manifestation of the component, compensating the geometry of the original model at the printer to create a compensated model, wherein the compensating includes removing a portion of the original model at the identified acute angle to form a compensated angle between the first surface and the ligament, wherein the compensated angle is smaller than the acute angle;
- and
- printing, with the printer, the physical manifestation of the component as a first physical manifestation of the component, based upon the compensated model, wherein the first physical manifestation of the component is more alike the original model than the compensated model due to distortions of the printer during printing.
A method of forming a component from an original model, the method comprising:
- prior to manufacturing any physical manifestation of the component, identifying an acute angle defined by a gap between a first surface and a ligament of the original model, wherein the original model is a virtual model;
- prior to manufacturing the physical manifestation of the component, compensating the original model to create a compensated model, wherein the compensating includes removing a portion of the original model from the first surface at the acute angle to form a compensated angle, wherein the compensated angle is included in the compensated model and the compensated angle is smaller than the acute angle, the compensated model comprising a first negative print region at the first surface;
- and
- forming the physical manifestation of the component, after creating the compensated model, by additive manufacturing, the physical manifestation of the component, based upon the compensated model such that the physical manifestation of the component, having a final acute angle, is more alike the original model than the compensated model due to distortions during forming of the physical manifestation of the component.
