In this work we present a first step to overcome the challenge of regaining and recycling valuable resources out of 3D printed parts by introducing the concept of Design for Disassembly (DfD), which describes the potential of products or multi-material components to be easily separated and recycled. Therefore, we prepared digital materials via a stereo lithography process by printing a fine layer of Material B inside the block of Material A. The layer of Material B should make the component easier separable. However, Material B should not affect the (thermo)mechanical properties of the component overall, especially not in the interval of the operating temperatures. The separation should be initiated only with an external impulse such as heat. With this impulse the disintegration of the material can be triggered, which leads to easier separation. This ensures that the component works normally at its operating temperature, but is recyclable at its end of life. For enabling this approach, thermally expandable particles (TEPs) are added to Material B to guarantee straightforward separation. To observe the influence of Material B and the TEPs on the whole component, three different specimen groups are printed, tested for their (thermo)mechanical behaviour, and compared. While group one was made from pure Material A, group two included the fine layer of Material B. Group three contained the TEPs (in different wt% ratios) in Material B to prove easier separation. Finally the specimens were printed with different layer directions to show the impact of the printing direction of the disassembly layer in the component.
