Thanks Kevin, You're absolutely right! the panel could be used for heating and noise insulation perfectly. I'm still thinking about 3D printing application from rubber and EVA (house, furniture, boat, etc.)
The principle is shredding the waste materials, old shoes, etc. (sorting/separating needed) to get bi-products (pieces), then we press them or even melt (heat) to form finished products: bricks and panels which are ready for construction or office furniture. Household purposes included also like plates, decorations, toys, strings, pots,...)
the finished products can be reused/recycled/remanufactured again and again after a specific period of time as long as they meet the quality requirements.
