This article provides a detailed comparison of injection molding and casting methods, focusing on their speed implications for rapid prototyping and production. It highlights that for initial small batches (20-50 units) and design iterations, casting (e.g., vacuum casting) is faster due to quicker, less expensive silicone mold fabrication (5-7 days). Conversely, injection molding, despite its longer initial tooling time (weeks to months), becomes faster for pilot runs (hundreds to thousands) and high-volume production due to its rapid per-part cycle times (seconds). The article emphasizes that the optimal choice depends on project volume, design stability, and urgency for initial parts, with KAIAO Rapid Manufacturing offering both services to meet diverse needs.

Unlocking Efficiency: Top Factors That Affect the Cost and Lead Time of Rapid PrototypingThe primary factors that affect the cost and lead time of rapid prototyping are part complexity and size, material choice, manufacturing technology (like 3D printing or CNC machining), required tolerances, post- Read More

The cost of rapid prototyping can range from as little as $75 for a simple 3D-printed model to over $10,000 for a complex, high-fidelity prototype created with CNC machining from production-grade materials. This wide price spectrum exists because the final cost is not a fixed number but a dynamic ca Read More

Rapid prototyping technologies are a group of techniques used to quickly fabricate a scale model of a physical part or assembly using three-dimensional computer-aided design (CAD) data. The most common types include **Fused Deposition Modeling (FDM)**, **Stereolithography (SLA)**, and **Selective La Read More

Surface finishes for CNC machined parts are a broad range of post-processing treatments applied to a part's surface to alter its properties, such as aesthetics, wear resistance, chemical resistance, and surface roughness. Choosing the right finish is a critical engineering and design decision that d Read More

The core difference between rapid prototyping and 3D printing is that rapid prototyping is a broad product development process or strategy, while 3D printing is a specific manufacturing technology or tool often used within that process. Think of it this way: rapid prototyping is the "why"—the goal o Read More
