| Abstract Scope |
This presentation shares a practical, experience‑driven view of deploying 3D printed patterns for sand casting in a production environment. The talk covers the evolution from early trials to foundry‑ready implementation, including pattern design considerations, material and printer selection, dimensional control, and surface finish strategies. Real‑world results are discussed, highlighting lead‑time reduction, tooling flexibility, and cost tradeoffs relative to conventional patternmaking. Common challenges such as pattern durability, qualification, foundry acceptance, and organizational adoption are addressed through lessons learned during iterative builds and production trials. The presentation focuses on where additive tooling delivers clear value today, where limitations remain, and how cross‑functional alignment enabled successful adoption in an industrial setting. |
