Hello everyone I am looking for a way to manufacture a parts that has a shape similar to a box and consists of multiple small parts, it is designed for 3d printing or injection molding process but i would like to use a method that wont involve burning plastic and create nocive fumes. For that i was wondering if there is a plastic for this purpose or i may use metal instead of plastic in a mold.. i could split the part and use a cnc but i won t prefer that
