Design and experimental study of a 3D printing waste regeneration device
Fusion Deposition Molding(FDM)is one of the widely used 3D printing technologies currently.FDM 3D printing gen-erating waste materials during the application process.These waste materials are mainly distributed sporadically in the user side and are difficult to collect centrally.What's more,there is no simple waste recycling and regeneration device,resulting in a large amount of waste being discarded or directly incinerated,which causing resource waste and environmental pollution.Based on the concepts of energy conservation,environmental protection,and waste recycling,a 3D printing waste recycling and regeneration de-vice was designed and manufactured to achieve the heating,melting,and extrusion of waste materials,which resulting in new con-sumables suitable for 3D printing.This has enabled the recycling and reuse of FDM 3D printing waste,helping to solve problems such as resource waste and environmental pollution.The operation and regeneration experiments were conducted on the device to verify the rationality of the design scheme and the regeneration capacity of the device.The control variable method was used to conduct regeneration experiments on five materials including ABS,PLA,PP,PE and PS,the influence of main operating parame-ters such as heating temperature and motor speed on the forming quality of recycled materials was obtained.The optimal operating parameters for the five materials were also obtained.
