Perhaps people may wonder: why do 3D printing products still need to be vacuum replicated after production?
The current mainstream processes for 3D printing are SLA (light curing) and SLS (selective laser sintering). The surface of products produced by SLA technology is smooth and delicate, but the strength is low and the toughness is poor; The products produced by SLS technology have good performance in terms of strength and toughness, but their surface is rough and lacks good surface smoothness.
At the same time, 3D printing adopts a layer by layer manufacturing method, which means its density is low and its strength is also low. However, the vacuum lamination process uses injection molding method, and its density is relatively high, so its strength is naturally high. Furthermore, there are various types of materials for vacuum replica products, such as transparency, ABS like, rubber like, color matching, etc., which means that one mold can be used to produce various types of products. Choosing 3D printing to produce products is just one way to make silicone molds faster. Often, 3D printed products cannot better verify their performance and structure. Therefore, we can choose vacuum replication technology to obtain our ideal components.
