This technical analysis, authored by the Chief Manufacturing Engineer at Kaiao Rapid Manufacturing, serves as a decision-making framework for B2B procurement managers navigating bridge production. It differentiates between the aesthetic flexibility of Vacuum Casting (ideal for <20 units with ±0.05 mm tolerance) and the mechanical rigor of Rapid Read More

This article, written from the perspective of a Chief Manufacturing Engineer, explores how the strategic integration of CNC machining and 3D printing mitigates financial and technical risks during hardware development. By utilizing specific data—such as CNC tolerances of ±0.001 inch and rapid 1-day lead times—the post demonstrates how physical validation prevents "Rule of 10" cost escalations. It provides a technical roadmap for B2B procurement managers to choose between additive and subtractive processes, ensuring design intent matches physical reality before investing in expensive mass-production tooling.

This article details when to choose plastic 3D printing over traditional manufacturing methods. It highlights that 3D printing is superior for rapid prototyping, complex geometries, low-volume production, and custom parts due to its speed, design freedom, and lack of tooling costs. Conversely, traditional methods like injection molding are better for high-volume production, achieving the lowest per-part cost, and when superior mechanical properties or specific material certifications are required. The choice ultimately depends on the project's volume, complexity, budget, and stage of development. Read More

This article provides a concise guide to choosing between CNC machining and 3D printing for rapid prototyping. It highlights CNC's strengths in precision, material strength, and production-like finishes for functional parts, with lead times as fast as 1 day. Conversely, it emphasizes 3D printing's advantages in handling complex geometries, offering rapid and cost-effective iterations for early-stage validation, typically within 4-6 days. The article details material comparisons, cost/lead time differences, and variations in surface finish and tolerances, concluding with a decision matrix to help users select the optimal method based on their project's specific needs.
