<![CDATA[3D printers have grown in popularity in recent years because of their ability to print objects quickly and easily. The material used to print objects on a 3d printer is called the filament. Using recycled materials to produce 3D printer filament is gaining popularity in the 3D printing industry. One material that can be recycled to make filament is waste bottles of the Polyethylene Terephthalate (PET) type. This research was conducted to see the effect of printing speed on object dimensional stability. In this study used an experimental method by designing variations in printing speed on a 3D printer and using waste bottle filament as raw material. Each variation of printing speed was repeated five times and the dimensions were measured using a micrometer. The results showed that printing speed affects the dimensional stability of 3D printing results from waste bottle filament.]]>
