In addition new materials like Carbon fiber and other composites with a very high stability have entered the prosthetic market [3].
For our prototype of the active driven knee prosthesis, we used the following components: - Mechanical build up: Combination of composite materials - Electric-drive: BLDC-Motor with a maximum power output of PMotor=200W - Kinematic solution: Bevel helical gearbox with mono axial knee axis - Energy source: Li-Ion-Battery - Sensor-System: Inertial Measurement Unit (IMU).
As the system should be easy to be produced, we decided to use a composite material for the housing.

As concrete is a highly variable material, there are many possibilities to use less traditional raw materials even for PCC, but the key is to achieve the specific properties mentioned above.
In addition, it has excellent anti-slip properties and good adhesion with cementitious materials, so it is widely used in road construction.
- Alkali activated materials, geopolymers: They are among the most widely used alternative binders in research for the construction industry because they reduce CO2 emissions and consume waste materials (FA, GBFS).

The laser micromachining is the process that omits small energy pulse laser beam on the surface of the workpiece and removes the material from the surface.
Because of the thermal process of the laser, the material melts and vaporizes away.
Then, it forms a crater on the surface around spatter of melting material, as shown in Fig.1.
