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

Group Assignment

My group assignment is to test overhangs, bridges, wall thickness and clearances on the lab printer. The group assignment page is currently a template, so I still need to add the measured limits and test-piece results. I cannot substitute general printing advice for those measurements.

For my object I designed a cube with a pipe running through the inside of it. An enclosed channel like that cannot be reached by a cutting or milling tool, so it has to be made by 3D printing. That is exactly why it cannot be made subtractively.

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, 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 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

I moved to the Creality v3 SE and turned it on. I inserted the removable disk containing the sliced file. First, I checked the printer leveling and confirmed it was correct. Then, I heated the nozzle to test the filament flow

The PLA nozzle temperature was set to 200 °C. because it is the ideal melting temperature for most PLA filament.that why i choosed 200 °C.

After that, I selected my file from the disk

started printing.

3D Scanning

3D scanning is a technology that captures the exact shape, size, and surface details of a real object and converts them into a digital 3D model.. It uses lasers, light, or cameras to measure the surface of the object

My scan subject is a Woodfix bottle and my planned tool is Kiri Engine on a smartphone. My earlier text described this as finished, but the capture and result images are not in my archive. I am keeping the scan marked as evidence pending.

To complete it, I need to record the capture setup, show overlapping views around the bottle at different heights, document the processing settings, and include a screenshot of the reconstructed surface. I will describe any gaps or failed regions visible in the actual result.

Still to add: capture photographs and the finished scan screenshot. I have not replaced them with generated images.
