Hello guys,
I will be working on my thesis this year. I am willing to create an extruder for 3d printing concrete. I want to use a secondary material as a support that will print with concrete at the same time. Once the concrete is cured I will remove this support material. I was thinking to use clay or wax as secondary material. I want to ask if there is any other material that I can focus on during my research which should be easy to remove once the process is complete. I can be water-soluble, melt with heat (Like Wax)...etc.
Let me know if you guys can think of any other material. I don't have a lot of money or infrastructure to work with advanced materials such as metal, polymers...etc. So the materials should be easy to find and work with.
