• One of the main problems brought by large-scale 3D printers is the lack of standardization of machines and the potential of low-quality products. If a company invests in an inexpensive 3D printer then the risk of a bad quality product increases. On the other hand, a high-end Large-scale 3D printer would cost millions of dollars to produce a trustworthy result. Regardless, the traditional manufacturing route will always be preferred by production companies. Many different 3D printers produce very different products, making there a lack of universal standards in 3D printing technologies. Therefore, manufacturers compare their products with other manufacturers' methods worrying that they would vary in terms of quality, strength, and reliability. This causes a continuous wariness in the 3D printing technology, making companies always judge the risks compared to the benefits.
