3D printing is a revolutionary technology. This method directly uses the product’s three-dimensional computer data to achieve a prototype of the product based on the principle of layer-by-layer stacking of discrete layers. SLA and SLS are two mature laser China Rapid Prototyping technologies, and the material used in SLA is mainly photosensitive resin. At Vowin Rapid, we offer SLA and SLS prototype in a variety of plastic materials.
