3D printing filament is the main asset in the development and manufacture of 3D objects. However, not all filament materials can be made easily. The difficulty level of 3D printing lies in the materials that are not commonly used. ABS and PLA are the easiest filaments to use, currently we are researching 3D printing filaments made from recycled disposable mask where machine specs are needed to enable 3D object fabrication. Recycled Disposable masks becomes an important research object when mask waste is widely used during the Covid-19 pandemic and currently it can be an alternative when these materials can be recycled into 3D printing filament. In this research also requires techniques to analyze typical filament materials that are adjusted for ambient temperature, filament thickness, nozzle temperature, and print bed temperature. In the design process, it is also necessary to set printing quality standards on the software used, such as the configuration of the raft printing support, the enable of the retraction. This study also analyzes the results of different objects for each filament diameter, filaments smaller than 1.75 mm will have a high vacancy rate on the object, while filament diameters with sizes larger than 1.75 mm will have high vacancy rates on the object. difficulties when entering the filament into the head print on 3D printing machine. It is also hoped that in this research, the 3D printing objects can be printed correctly and can be used as a reference to determine which is better than other filament material schemes and adjustments to different techniques.

Disposable mask waste can decompose into the environment for hundreds of years, so waste management is needed to support sustainable and environmentally friendly products. One solution to dealing with disposable mask waste is the manufacture of 3D printing filaments. A product is said to be sustainable and environmentally friendly if it can be ascertained that the product has minimal impact on the environment. The method used to assess the environmental impact of a product is Life Cycle Assessment. This research is limited to cradle-to-gate by analyzing the manufacture of filaments made from disposable mask waste mixed with polypropylene. Based on calculations, it is known that the production of filaments made from mask waste has the potential to produce greenhouse gases, acidification, and eutrophication. However, this research can be a good step to produce products made from waste and supporting sustainability.
