Abstract
There is provided an additive manufacturing system and method for creating a seamless fabric and/or foam product comprising different properties in different designated sections along the fabric and/or foam product. The system and method comprising depositing polymer liquid droplets via a precise liquid placement (PLP) head, depositing polymer liquid droplets via a high-volume-low-resolution head, and controlling operation of the precise liquid placement (PLP) head and of the high-volume-low-resolution head, thereby controlling the different properties of the seamless fabric and/or foam product, via a computerized control system.
Claims25
An additive manufacturing method for creating a seamless fabric and/or foam product comprising different properties in different designated sections along the fabric and/or foam product, the method comprising:
- depositing polymer liquid droplets on a printing surface via a precise liquid placement (PLP) head;
- depositing polymer liquid droplets on a printing surface via a high-volume-low-resolution head;
- and
- controlling operation of the precise liquid placement (PLP) head and of the high-volume-low-resolution head, thereby controlling the different properties of the seamless fabric and/or foam product, via a computerized control system, wherein controlling the operation of the precise liquid placement (PLP) head and of the high-volume-low-resolution head comprises controlling continuous or non-continuous liquid droplets depositing, the amount of liquid deposited in every deposition session, or at any given series of spray session, the type of liquid material applied per every session of droplets application, the order and duration of materials applied per each session of droplets deposition, or any combination thereof.

An additive manufacturing system for creating a fabric and/or foam product comprising different properties in different designated sections along the fabric and/or foam product, the system comprising:
- a precise liquid placement (PLP) head configured for deposition of accumulated liquid droplets;
- a high-volume-low-resolution head configured for deposition of accumulated liquid droplets;
- wherein resolution of deposition of the precise liquid placement (PLP) head is higher than resolution of deposition of the high-volume-low-resolution head,
- a printing surface configured to receive the accumulated liquid droplets thereon;
- and
- a computerized control system configured to control operation of the precise liquid placement (PLP) head and of the high-volume-low-resolution head, thereby to control the different properties of the fabric and/or foam product,
- wherein each of the precise liquid placement (PLP) head and the high-volume-low-resolution head is attached to a movable and tiltable holding device, said movable and tiltable holding device configured to move each of the precise liquid placement (PLP) head and the high-volume-low-resolution head along X, Y, and Z axes, to roll in RX, RY, and RZ axes, thereby to control the angle of deposition direction and the distance and angle between each of the precise liquid placement (PLP) and the high-volume-low-resolution heads and the printing surface,
- wherein each of the precise liquid placement (PLP) and the high-volume-low-resolution heads comprises nozzles through which the liquid droplets exit the heads,
- further wherein the pump controlling each nozzle comprises controlling different amounts of liquid disposed from per each nozzle, different materials disposed from per each nozzle, timing of nozzle operation, or any combination thereof.
