Abstract
A device includes a cylindrical lattice structure inside of a cylindrical tube. The cylindrical lattice structure includes compartmentalized one or more longitudinal flowable paths formed by an additive manufacturing process. A material is introduced in a flowable state into one or more upper apertures of the one or more longitudinal flowable paths to fill the cylindrical lattice structure in a compartmentalized arrangement that provides stiffness to the device.
Claims15
A device comprising:
- a cylindrical lattice structure of compartmentalized one or more longitudinal flowable paths formed by an additive manufacturing process;
- and
- a cylindrical tube that receives the cylindrical lattice structure;
- a material that is introduced in a flowable state into one or more upper apertures of the one or more longitudinal flowable paths to fill the cylindrical lattice structure in a compartmentalized arrangement that provides stiffness to the device.
