What can AM processes create for paper pulp tooling processes?

Additive manufacturing (AM) processes are particularly advantageous for creating porous, rigid polymer molds for paper pulp tooling. The ability of AM to produce intricate geometries and customized designs enables the fabrication of molds that can enhance the drainage of excess water from the pulp during the papermaking process. These porous molds facilitate the process while retaining structural integrity, which is essential for efficient production.

The rigid nature of the polymer used in these molds ensures they maintain their shape under the conditions experienced during pulp processing, while the porosity allows for better filtration and air flow. This combination of properties makes porous, rigid polymer molds highly suitable for the specific demands of paper pulp tooling, helping to optimize both the quality and speed of the manufacturing process.

In contrast, creating only solid molds or non-porous rubber molds doesn't effectively address the fluid dynamics involved in pulp processing, and metal molds, while robust, can be prohibitively heavy and may not be conducive to the same level of complexity or customization that polymer molds can provide.
