A method for forming a component includes estimating a dosing plan for powder of a powder bed fusion (PBF) system needed to form the component. The dosing plan includes powder dosing requirements needed per layer to form the component. The method includes providing the dosing plan to a controller of the PBF system. Further, the method includes regulating the powder being supplied to a build chamber of the PBF system from a supply chamber of the PBF system based on the dosing plan. In addition, the method includes additively manufacturing the component via the PBF system using the powder.

Systems and methods for estimating powder dosing in additive manufacturing processes

A method for additively manufacturing a component includes generating, via imaging software, a plurality of slices of a support structure of the component based on component geometry. The method also includes melting or fusing, via the additive manufacturing system, layers of material to a build platform of the component so as to form the support structure according to the plurality of slices. The support structure includes a lattice configuration having of a plurality of support members arranged together to form a plurality of cells. Further, the method includes melting or fusing, via the additive manufacturing system, a component body to the support structure. After the component body solidifies, the method includes removing all of the support structure from the component body to form the component.

Methods for additively manufacturing components using lattice support structures

A method for additively manufacturing a component includes receiving, via an additive manufacturing system, a geometry of the component and melting and fusing, via an energy beam of the additive manufacturing system, material layer by layer atop a build platform according to the geometry so as to build up a plurality of layers that form the component. The method also includes determining a surface area change from one of the plurality of layers to the next based on the geometry. Further, the method includes temporarily discontinuing melting and fusing of the material by the energy beam between building of one or more of the plurality of layers so as to provide a delay after building one or more of the plurality of layers when the surface area change is above a predetermined threshold. As such, the delay allows for one or more previously built layers to at least partially cool so as to eliminate and/or reduce build failures from occurring in the final component.

Methods for additively manufacturing components with reduced build failures caused by temperature variations

A tangible, non-transitory, machine-readable medium including instructions presents a graphical user interface (GUI) and the GUI provides an indication of two or more output file types. Further, the medium including instructions receives an indication of a selection of at least two of the two or more output file types. Moreover, the medium including instructions generates corresponding output files for the selection of the at least two of the two or more output file types by accessing an applicable computer-aided-design (CAD) model associated with a part number. Also, the medium including instructions generates corresponding output files for the selection of the at least two of the two or more output file types.
