    <p style="justify-content: center"><strong> 3D scanning is the process of analyzing and capturing a real object or environment and creating
    a virtual 3D model with the help of the collected data. A 3D scanner, then, is the tool responsible for executing this capturing. <br>
    3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file.
    The creation of a 3D printed object is achieved using additive processes. In an additive process an object is created by laying down successive layers of material until the object is created. Each of these layers can be seen as a thinly sliced horizontal cross-section of the eventual object.
    3D printing is the opposite of subtractive manufacturing which is cutting out / hollowing out a piece of metal or plastic with for instance a milling machine.
    3D printing enables you to produce complex shapes using less material than traditional manufacturing methods. <br>

    So we five member in group, the Fab Academy provides different jpg images to test the printer.The image include some supports and unsupports type
    printing. We have developed the all design in our 3D printers. The 3D printers available in our lab has the following specification: <br>
    Make: Fracktal Work 3D printer <br>
    Build Volume: 200x200x200mm <br>
    Nozzle: 0.25, 0.4(Default), 0.6, 0.8mm(Direct Drive Extruder with E3D V6 Hotend) <br>
    Build Surface: Flexible PEI (AC Heated Bed)<br>
    SD Card input wild LCD Display (Stand alone printing) <br>
    Power Failure ressurection - Never lose a print to power failures again. <br>
    Multi Filament Capability: PLA, ABS, Flexible, Composite Materials (Wood Fill, Bronze Fill, etc), Nylon 618 <br>
