3D SCANNING AND PRINTING

Assignment

Design and fabricatea a small 3D print a very small object (a few cubic centimeters in size, limited by printing time). The object must have a geometry that would be difficult or impossible to produce using subtractive manufacturing methods such as cutting, carving, or milling

3D PRINTING

Design

Begin by opening SolidWorks, and select Part to create a new part file for the design

I selected the Front Plane as the reference plane for the initial sketch, drew a square to define the base of the cube, and then used the Extrude feature to create the 3D shape

After creating the cube, I created the new sketch on the same Front Plane that was used to sketch the cube line that would serve as the center path for the pipe passing through the cube

Next, I navigated to the Features tab and selected Swept Cut to remove material along the previously defined path, forming the hollow pipe inside the cub

The Swept Cut successfully removed material along the defined path

After completing the design, I saved the model as an STL file to prepare it for slicing and 3D printing

After saving the model as an STL file, I launched Creality Slicer and imported the design.

After import, I selected the “Tree” support type in Creality Slicer to optimize material usage and provide better support for overhanging sections

After selecting the Tree supports, I set the infill density to 15% to balance material usage with structural strength

After setting the infill to 15%, I clicked the Slice in Creality Slicer to generate the toolpath and prepare the model for 3D printing

Once the slicing process was complete, I exported the sliced model by selecting “Save as G-code” in Creality Slicer. This file contains all the instructions needed for the 3D printer, including movements, speeds, and extrusion settings
