This article confirms that plastic 3D printing is indeed strong enough for many functional prototypes, thanks to advancements in materials and technologies like SLS, FDM, and SLA. It emphasizes that achieving sufficient strength depends on selecting the right printing technology and engineering-grade materials (e.g., Nylon, PC, ULTEM), optimizing part design for additive manufacturing, and utilizing post-processing techniques like annealing or infiltration. While traditional methods remain superior for extreme loads or high-volume production, 3D printing offers significant advantages for rapid, cost-effective functional validation. Read More

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

What Matters Most When Choosing a Prototype Supplier?When choosing a prototype supplier, the most critical factors are their technical capabilities, communication and project management, quality control, and speed/lead times, as these directly impact the accuracy, reliability, and timely delivery of Read More

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.
