The new W series is a resin for light-curing 3D printers that features ultra-low viscosity (less than 30 mPa·s) and can be washed with water. It can be easily cleaned with water, warm water, or a mixture of ethanol without using alcohol, thereby improving the efficiency of post-processing. Since it does not use IPA, it significantly reduces the constraints of fire safety regulations and the burden of waste liquid disposal, which is a major advantage. You can use it with peace of mind while ensuring safety in the working environment. Furthermore, it combines high strength, high durability, and high resolution, making it suitable for a wide range of applications from prototypes to practical parts. It has a proven track record in sprint applications, and its reliability has been demonstrated.
