5. 3D Scanning and Printing
This week I worked on modeling and learned what the printing process is like on a 3D printer.
Description of the work process of the week05
The previous weeks I told you about the design of a piece for my final project, it is a small shelf. On this occasion I will talk to you about the impression of this piece.
The first thing I did was save my modeling in an STL file. Before starting to print, I opened the SINDOH printer program on the computer. When I loaded it, I converted it to G code, this will allow me to send it to the printer and have a quality print.
Within the configuration made to the file, was modifying the scale, the supports (it should be noted that this piece did not need many supports, only two in a space between the base and one of the openings) and saving so that it could finally go to the printer.
What this will do is give us an estimated printing time and it is configured to begin for this process, the machine heats the PLA filament and that's it, it starts printing. The machine I used was the SINDOH 3DW0X printer with PLA material filament with high cooling and soldering speed.
For the scanning part, I started by choosing a part to be able to scan. This part is very important that it does not have shiny parts. Once I had the part, I opened the scanning program of the Ein Scan-SE machine and started with the calibration. This was done by for the first time when you use the machine or on some occasions when it is required, this serves so that your piece is aligned in the best way and a correct scan is made. Following the steps that the program asks you to, you will rotate the plate so in which the 3 white dots come back, once the calibration was successful, you place a white paper this serves for a correct white calibration.
After the calibration, we proceed to the scan using a small dinosaur (which by the way I stole from my nephew), what the machine did was rotate it to be able to capture all the possible angles of the piece, there were parts that could not be formed in the scanning is why I turned the dinosaur on its side so that, when it came to turning again, it could capture the missing parts.
And ready! The piece is scanned and ready to be converted into a 3D file so it can be printed. Something I didn't mention was that the program gives you the option to scan your file with textures, this serves to give more realism to the piece.
reflection and analysis
When I wanted to print my object, when I started printing the PLA broke, and that stopped the printing and I had to start again, this was because the filament was wet, which is why I recommend having the filaments in places free of humidity if not you use them frequently.
