Top grade design has rich experience in equipment design, which is also the key to establish long-term design cooperation between Xi'an National Material Additive Innovation Center and Top grade. Through the design process of far view/near view/experience, we construct the spatial level of users and products, which is different from small products. The visual space sense and hierarchy sense of large equipment are particularly important. Through the design experience and theoretical methods accumulated by Top grade for many years, it has injected new identification features and serialization features into the product, which is patchwork and unique.
