Additive Manufacturing of a Shredder

Shredders have become an indispensable pail of modern life. Variety of shredders are available for different purposes such as Paper shredders, metal shredders, etc. They come in different sizes, ranging from small sizes for household applications to large sizes for industrial applications. These shredders are used to break down the material into smaller pieces so that they could be disposed of more easily and efficiently. Currently, these shredders are majorly used by large industries for waste disposal systems. This process of shredding the large waste produced by common households by itself will take an enormous amount of energy when accumulated overall as they mainly use fossil fuels for this purpose. This can be reduced by reducing to an extent if all the possible household waste is manually shredded at houses themselves instead of taking it to the industries. For this purpose. in this study, an economical shredder that has the capability to plastics, wood, and few low strength metals like aluminium has been designed. Beginning with a base design and have worked to improvise it in considered parameters. These parameters are the shredder being efficient, economical, and lighter. The design was repaired and optimized in Meshmixer Software and then sliced in Ultimaker Cura Software and was made 3-D printable. The developed model was found to be more helpful than the conventional shredders, as to its economical viability, ease in use and handling, and to its efficiency in shredding the plastics. As a result, a successful and efficient design of a portable shredder has been developed.
