Abstract
A method of forming a part using additive manufacturing may include receiving, at a computer numeric controlled (CNC) machine, a computer aided design (CAD) model of the part. The method may further include dividing the CAD model into plurality of sections. The method may further include slicing each of the plurality of sections into a plurality of layers. Each section may include a distinct set of print parameters. The method may further include depositing a flowable material onto a worktable according the set of print parameters for each section of the of the plurality of sections to manufacture the part.

A system for forming a part using additive manufacturing, the system comprising:
- an extruder having an extruder screw;
- an applicator assembly including a nozzle connected downstream of the extruder;
- a plurality of servomotors for positioning the applicator assembly;
- and
- a controller that is configurable to:
- control the extruder, and
- control the servomotors while the applicator assembly deposits a material onto a surface via the nozzle during an additive manufacturing process,
- wherein the applicator assembly is configurable to form at least one section of the part via the additive manufacturing process,
- wherein the at least one section is formed using a set of print parameters, wherein the set of print parameters includes:
- a seam offset parameter that determines that a start location and a stop location are offset from one another between print layers such that the start location of a first layer is offset from the start location of a second layer and the stop location of the first layer is offset from the stop location of the second layer.
An additive manufacturing system, comprising:
- an extruder coupled to an applicator assembly, the extruder including a screw;
- a nozzle connected to receive material from the extruder;
- and
- a controller that is configurable to:
- control the extruder,
- cause the applicator assembly to deposit the material onto a surface via the nozzle to manufacture a part during an additive manufacturing process, wherein, during depositing the material, the screw of the extruder rotates in a first direction,
- wherein the applicator assembly is configurable to form at least one section of the part via the additive manufacturing process,
- wherein the at least one section is formed using a first set of print parameters, wherein the first set of print parameters includes:
- a seam offset parameter that causes a start location and a stop location for depositing the material to be offset from one another between at least two layers, and
- a reverse melt parameter that causes a change in the direction of rotation of the extruder from the first direction to a second direction that is opposite the first direction.
An additive manufacturing system, comprising:
- an extruder having an extruder screw;
- an applicator assembly including a nozzle fluidly connected downstream of the extruder to receive material from the extruder;
- and
- a controller that is configurable to:
- control the extruder;
- and
- control the applicator assembly to deposit the material onto a worktable via the nozzle during an additive manufacturing process,
- wherein the applicator assembly is configurable to form a plurality of sections of a part, including a first section and a second section, via the additive manufacturing process, wherein:
- the first section is formed using a first set of print parameters, wherein the first set of print parameters includes:
- a seam offset parameter that determines that a start location and a stop location of deposition are offset from one another between layers.
