Based  on your predefined project needs, you have the option to choose from  several types of FDM 3D printers. The FDM 3D printing machines differ  from each other primarily in two aspects –mechanical nature and  operational coordinate system. Hence, you need to compare the FDM 3D  printers manufactured by different companies. While  planning the FDM 3D printing process, you must focus on choosing the  right modeling and support materials. The modeling material will form a  solid three-dimensional object, while the support material will provide  support to the part as it is 3D printed. https://www.aurum3d.com/FDM-3d-printing-service/
