Copper Filament PLA is one of the most popular forms of 3D printing plastic for a number of reasons, with a major factor being its lack of odour and ease of use. You can use this PLA filament to 3D print whatever your imagination can muster. PLA is made from renewable resources, namely the starch from fermented plants such as corn and cassava, along with others. This means that you can print to your heart’s desire without worrying about the same issues of sustainability associated with traditional plastic made from fossil fuels. Exercise your creativity without having to worry about quality and consistency with a roll of Clavius3D PLA Filament.
