I want people to discuss under that question about the possible materials which are used in Philae. What are their manufacturing process and I am also interested in electrochemical manufacturing processes. If anyone send me a beneficial link or source about it I will appreciate.
Thanks in advance.
Philae was, like most other spacecraft, built with materials that had fairly strict requirements. But the wide variety of components (perhaps a few tens of thousands of discrete parts) means that it is impossible to list the materials that were used.
Can you be more specific about the subsystems that you are interested in, and the properties of interest to you?
(disclaimer: I worked on a part of the MODULUS sample-handling device)
Choosing spacecraft materials (especially for long duration flights) is a VERY large field. To get an overview, you could download (for free) these proceedings on a relevant conference at this link:

The literature section of these Proceedings should allow you to search for more specific information.

and many more....
The main structure of Philae is made of carbon fibre and carbon fibre with aluminum honeycomb.
Obviously, there is a huge number of other materials used for the subsystems.
Additional structural elements and mechanisms are to a large extent made of aluminum, titanium and certain, space qualified, plastic materials.
Do you have any specific interest in a particular material?
