FAQ

Q1: Can molded pulp be CNC machined?

A: Yes — milling, routing, and laser cutting work on pulp for prototypes and precision features.

Q2: Does machining weaken the part?

A: Machining cuts fibers, so machined edges are weaker than molded edges; keep structural areas molded.

Q3: When is machining worth it?

A: For prototypes and low volumes where mold tooling is not justified.
