Abstract
A controller of an additive manufacturing system including an extruder nozzle is programmed to: cause the extruder nozzle to deposit one or more first material segments with at least one first locking portion having a first shape; and cause the extruder nozzle to deposit one or more second material segments with at least one second locking portion having a second shape; wherein the second shape of the at least one second locking portion engages with the first shape of the at least one first locking portion, whereby the at least one second locking portion forms an interlock with the at least one first locking portion.
Claims20
A non-transitory computer-readable medium associated with an additive manufacturing system comprising an extruder nozzle usable to deliver an at least partially liquefied material at controlled locations, the computer-readable medium encoding instructions operable to cause a controller of the additive manufacturing system to perform operations comprising:
- controlling the extruder nozzle to deliver the at least partially liquefied material at the controlled locations in a set of three or more layers of a product, the controlling comprising
- causing the extruder nozzle to deposit one or more first material segments, in at least a first layer of the set of three or more layers of the product, with at least one first locking portion having a first shape, which is defined by at least one gap in the at least a first layer of the set of three or more layers of the product, and
- causing the extruder nozzle to deposit one or more second material segments, in at least another layer of the set of three or more layers of the product, with at least one second locking portion having a second shape, which protrudes into the at least one gap in the at least a first layer of the set of three or more layers;
- wherein the second shape of the at least one second locking portion engages with the first shape of the at least one first locking portion, whereby the at least one second locking portion forms an interlock with the at least one first locking portion.
A computer-implemented method performed using an extruder nozzle associated with an additive manufacturing system, the computer-implemented method comprising:
- directing the extruder nozzle to deliver at least partially liquefied material at controlled locations in a set of three or more layers of a product, the directing comprising
- depositing one or more first material segments, in at least a first layer of the set of three or more layers of the product, with at least one first locking portion having a first shape, which is defined by at least one gap in the at least a first layer of the set of three or more layers of the product, and
- depositing one or more second material segments, in at least another layer of the set of three or more layers of the product, with at least one second locking portion having a second shape, which protrudes into the at least one gap in the at least a first layer of the set of three or more layers;
- wherein the second shape of the at least one second locking portion engages with the first shape of the at least one first locking portion, whereby the at least one second locking portion forms an interlock with the at least one first locking portion.
