Another accepted method of the composite materials manufacturing is the in situ synthesis method.
A considerable part of such materials are composite materials based on aluminum or its alloys with a unique combination of physical and mechanical properties [1, 2].

Such tasks can be solved through the development and creation of new composite materials by means of combining the existing raw materials or by means of using secondary raw materials based on industrial wastes from regional enterprises.
The of scope of the rational spheres in which polymer-cement materials are applied is not yet complete, since it is a rather young type of construction materials.
Applying local secondary raw materials for the compositions of FTPS opens a new spectrum of spheres where they can show themselves better than the traditionally used materials for waterproofing and corrosion protection of construction materials and structures.

Micro milling has the advantage that the materials are generally not degraded by chemical substances, heating procedures or electromagnetic radiation.
Plastics remain a primary option of all the materials commonly used in bioreactor resource, due to their many favorable properties and their compatibility for biological applications.
For these reasons, plastics have been considered to be reliable and robust materials for bio reactors since years.
The machine is able to process a wide range of materials.
