What has contributed to the decreasing costs of 3D printing technology?

The decreasing costs of 3D printing technology can be largely attributed to the increased availability of materials. As more manufacturers and suppliers begin to offer a wider variety of printing materials, competition increases, which tends to drive prices down. Additionally, advancements in material science have led to the development of new, more affordable materials that can be easily sourced, further contributing to cost reduction.

With a broader range of materials available, 3D printing becomes more versatile and accessible for various applications, making it a more attractive option for businesses and consumers. This expanded choice not only supports innovation in design and manufacturing but also helps to lower the overall cost of producing 3D printed components.

The other factors listed do not support a decrease in costs. For example, strict regulations would typically add to operational costs rather than reducing them, while higher operational complexity is likely to necessitate more training and infrastructure, leading to increased expenses. Limited design capabilities would restrict the technology's usefulness and could lead to higher costs due to the need for customization and rework.
