The basic principle is shown in the right picture, and two-dimensional layer is made by X—Y which is driven by the working table, which is based on the shape of the molten material.

The advantage is that the use of the material range is optional, such as casting paraffin, nylon, thermoplastic, ABS, etc..

At present, the majority of the material used is ABS material. The strength of molding is good in the line direction, but it is easy to crack in Z direction.
