This thesis seeks to establish whether recycled E-waste rABS from Stena Recycling AB in Halmstad, Sweden, can be effectively utilized in additive manufacturing processes and if it can be applied similarly to virgin ABS. Results show that it is possible to apply the rABS granules on 3D-printing but with mechanical property losses and cosmetic losses. The result shows a loss in tensile strength between rABS and virgin ABS.The difference of the best performing rABS versus the best performing virgin ABS results in a mean loss of 32% and best performing loss of 25%. The research is confined to filament extrusion and experiments were conducted in FabLab Halmstad utilizing 3Devo Composer with 15 different temperature settings. The filament was then used in Prusa MK4 where three tensile tests in 0, 45 and 90 degrees with 5 iterations per test and per setting. The 3D-printed recycled tensile tests results are compared to tensile tests made from virgin ABS. The conclusion is that there are significant mechanical property losses and with poor printability compared to store bought ABS filament.
