3D printed tooling for pulp molding process

A mold created using additive manufacturing techniques, comprising:

• a product surface and an interior matrix;
• at least one transverse polymer layer;
• and
• at least one infill polymer layer;
• wherein the at least one transverse polymer layer comprises a plurality of adjacent columns of superimposed filaments;
• wherein the superimposed filaments are configured to include at least one bead;
• wherein at least one channel is formed between adjacent columns of the superimposed filaments;
• wherein the at least one bead is placed as an over extrusion at an end of each of the superimposed filaments to form at least one pore on the product surface of the mold;
• wherein the product surface of the mold comprises a plurality of pores formed between beads of adjacent columns of superimposed filaments, wherein the pores are configured to prevent the ingress of a fiber into the interior matrix of the mold;
• and
• wherein the at least one infill polymer layer is deposited on the at least one transverse polymer layer, wherein the at least one infill polymer layer stabilizes the at least one transverse polymer layer.
