Since the beginning of 3D printing, multiple technologies have been developed, the purpose of which is to convert digital models into physical models. To reach the goal, each of the technologies has different techniques, developments, and results.
FDM 3D Printing Technology
DM means Fused Deposition Modeling. In this type of modeling, the material is typically deposited in single layers, which fuse together and create a 3d object. So, how does it work? First, a 3d model files in “.OBJ” or “.STL” format is imported into a software program called a slicer. Simplify3D, Slic3, and Cura are some great examples of the slicer software program.
This software slices the object into simple separate layers and creates G-code, which tell the printer where it should move and control the parameter like temperature and print speed. Next, the G-code is sent to the printing machine where the nozzle starts heating and melting the filament. The object is then built layer-by-layer with all successive layers fusing on top of each other. The process is repeated until the print is completed.
FDM 3d printing is among the popular forms of 3d printing that is mostly suitable for home use. Its mechanism is simply allowing the user to print 3d object in an effortless and reliable way. In addition, the FDM printer is not expensive and its price range between $200- $400. Though these printers require a good deal of calibration and tinkering to print optimally, they can also produce 3d models with a moderate amount of strength and detail. Moreover, these printers have complications in producing complex models and professional grade prototypes. So, if you are looking to print simple 3d projects, you should buy an FDM printer.
