Abstract
In an example in accordance with the present disclosure, a fiber molding screen is described. The fiber molding screen includes a first region and a second region. The fiber molding screen includes a first set of pores formed within the first region. Each pore of the first set of pores has a first pore trajectory angle between a longitudinal axis of the pore and the first region surface. The fiber molding screen also includes a second set of pores formed within the second region. Each pore of the second set of pores has a second pore trajectory angle between a longitudinal axis of the pore and the second region surface. The second pore trajectory angle is different than the first pore trajectory angle.
Claims12
A method comprising:
- for each of a plurality of regions of a fiber molding screen to be used to manufacture a molded fiber product in a shape of the screen by suctioning a slurry of fiber through the screen such that the molded fiber product is formed as the fiber which collects against a surface of the screen via the suctioning:
- determining, by a processor, a tilt angle of the surface of the screen in the region relative to a reference surface, where a first region of the screen of the screen has a smaller tilt angle than a second region of the screen;
- determining, by the processor, a porosity of the surface of the screen in the region, where a third region of the screen has a greater porosity than a fourth region of the screen;
- and
- calculating, by the processor, a pore trajectory angle for pores within the region relative to the reference surface, based on the tilt angle and the porosity of the region, such that the molded fiber product when manufactured using the screen has a specified thickness that is uniform across all the regions of the screen;
- and
- additively manufacturing the fiber molding screen such that the pores within each region of the screen have the pore trajectory angle calculated for the region.
A non-transitory machine-readable storage medium encoded with instructions that when executed by a processor, cause the processor to perform processing comprising:
- for each of a plurality of regions of a fiber molding screen to be used to manufacture a molded fiber product in a shape of the screen by suctioning a slurry of fiber through the screen such that the molded fiber product is formed as the fiber which collects against a surface of the screen via the suctioning:
- determining a tilt angle of the surface of the screen in the region relative to a reference surface, where a first region of the screen of the screen has a smaller tilt angle than a second region of the screen;
- determining a porosity of the surface of the screen in the region, where a third region of the screen has a greater porosity than a fourth region of the screen;
- and
- calculating a pore trajectory angle for pores within the region relative to the reference surface, based on the tilt angle and the porosity of the region, such that the molded fiber product when manufactured using the screen has a specified thickness that is uniform across all the regions of the screen;
- and
- causing the fiber molding screen to be additively manufactured such that the pores within each region of the screen have the pore trajectory angle calculated for the region.
