3D Printing and Sacnning

In this page there is a link for the week 5 group assigment which is on 3D printing and scanning. The purpose was to test the design rules for the 3D printers we have. I have made a dsign rules for printer in the lab.
Group assigment

Individual assigment
Design and 3D print an object (small, few cm3, limited by printer time) that could not be easily made subtractively
3D scan an object (and optionally print it)

I designed a small basin to print using Fusion, then save the file as STL file to slice in the 3D printer software.
The the STL file opened using Creality Print 6.0 software to give the image size and convert to the G-code that can be read by the 3D printer.
In 3D printing, slicing refers to the process of converting a 3D model (typically in STL, OBJ, or 3MF format) into layers (slices) and generating the toolpath instructions (G-code) for the 3D printer to follow.

What is G-code in 3D Printing? G-code (Geometric Code) is the language used by 3D printers and CNC machines to control movements, extrusion, temperature, and other print parameters. It consists of a series of commands that tell the printer how to build a model layer by layer.

I used scale tool to resize the 3D model to the desired print size, and also sliced used slice tool to prepare a print.

To generate the G-code on the slicing software, go to the file menu then click export. Select export G-code then select the directory where the file will be saved.
3D Printing

After generating the G-code for printing, I took my file to the printer. I tested the printer with different ready made models and align them with my design rules.
Below is the printer information for my printer.

I imported the model into the printer using memory card in the forma of a G-code, then selected it to be printed. The printer done pre-heating based on the design rule set for that printer.
The printer used the white PLA filamanet for printing the model. In the first picture below, printing started with high speed and the qualitywas poor, it then improved after lowering the speed.


The final product of the is below.


I also used another different printer (Ultimaker printer) to test PVA filament, the guality is far different from the PLA filament.


3D scanning
For 3D scanning I used Creality scanner to scan my obejcts.
