Additive manufacturing (AM), or three-dimensional (3D) , is the process of creating a 3D solid object of nearly any shape from a digital model. The technology has lead to innovations in a vast …

Additive manufacturing is the process of creating an object by building it one layer at a time. It is the opposite of subtractive manufacturing, in which an object is created by cutting away at a solid block of material until the final product is complete. Technically, additive manufacturing can refer to any process where a product is …

In rubber manufacturing, rubber sheets are dipped into "batch-off" liquids to prevent the sheets from sticking together when they are folded for storage. Rhenodiv BO-3300 Pearls is the state-of-the-art solution for a dust-free batch-off process which also minimizes the need for cleaning the production equipment.
