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
