Solid formless forming method

Solid formless forming method

Solid free form fabrication (SFF), abbreviated as SFF, was a new ceramic forming process proposed by H. Marcus from the University of Texas Austin and E. sechs from MIT in the early 1990s, using the concept of integrated manufacturing. This method is also translated as "solid free form manufacturing".

The Process Principle and Process of Solid Formless Forming

The basic principle and process of solid dieless forming technology is to directly use the CAD design results of a computer to slice and segment complex three-dimensional components through computer software, forming pixel unit files that can be executed by a computer. Then, through external devices similar to computer printouts, the ceramic powder to be formed is quickly formed into actual pixel units, and the results of unit by unit stacking can directly form the required three-dimensional components.

The Process Characteristics of Solid Formless Forming

Compared with traditional forming methods, solid formless forming technology has the following characteristics:

(1) During the forming process, no molds or models are required to participate, making the production process more integrated. The manufacturing cycle is shortened and production efficiency is improved.

(2) The geometric shape and dimensions of the molding machine can be changed at any time through a computer software processing system, without waiting for the design and manufacturing of the mold, which greatly shortens the development time of new products.

(3) Due to the fact that the size of external formed printing pixel units can be as small as micrometers, Therefore, this forming method can Micro Electroceramics devices for life science and small satellites have been fabricated.

(4) Combined with modern intelligent technology, it will further improve the level of ceramic preparation industry and match the progress of this field with other industrial manufacturing fields.
