3D printing is a manufacturing process widely used in the 4.0 Industry era. One of the concepts of 3D
printing is to make prototypes, whether it is for industrial purposes or studying purposes. Knowing that a prototype
is only needed in the early stages of any process, it is bound to be redundant in a short time; thus, the plastics used
to prototype using the 3D printing technology are now labeled as waste. Since most plastics used for 3D printing
are thermoplastics, they can be recycled to live another purpose. This research aims to design a crusher dedicated
to processing 3D printing waste as the first step towards recycling these wasted materials. This step encourages
students to comprehend the process of designing and manufacturing such equipment while also opening doors for
the faculty towards recycling 3D printed plastics. The designing process consists of surveying the materials
commonly used for 3D printing, calculating the machine elements, choosing the mechanism needed to destroy the
material, and designing a model from the calculations. The outcome of the design is a device that can crush and
destroy PLA (Polylactic Acid) and ABS (Acrylonitrile Butadiene Styrene) plastics into pieces ready for recycling.
