Individual assignment:
Design and produce something with a digital process not covered in another assignment, documenting the requirements that your assignment meets, and including everything necessary to reproduce it.🤨
For this week I will design a cup or a chocolate bar or both together, Honestly I have no Idea what I’m going to do but I will start looking for a logo {Chocolate company in the local market} then I will try to create a cup like the logo I’m going to choose.😬
The technology I’m going to use is (3D Food printing) and I will be using PROCUSINI.
I will Start now with the design process, I will use also OnShape; I will go very fast in the design process but for more information about the process please refer to my previous documentation about how to use OnShape.
Brainstorming
I will start by looking for a company LOGO works in chocolate industry in the local market.
I found that there is a few companies in the local market and its hard to search for these companies as they are not that popular, but however I have chose one called BUONO
The Logo I want to use
-
This is the entire logo for this company.
-
I will use the graphic side of there logo and create my design.
- Then I will use this in my design to create the cup.
Now I will go to OnShape and create my design
- Before That I will need to trace this file and change it to DXF so I can manipulate it using OnShape.
Raw File
Design
Now I will use OnShape to create my design from the logo file.
- I will Start by opening OnShape and creating new sketch.
-
I will Draw a circle with 40mm Diameter.
-
Then I will create another plane and I will offset it from the top plane by the height of the cup I want to create.
-
Then I will Import the DXF file and place it on the new plane.
-
But before this I have to create sketch on the new plane to import the LOGO on it.
- Then I will place the DXF file on the sketch plane.
- Then I will to loft the both sketches; But this is not gonna work until I close the sketch first.
- After making the sketch close
- Now I will use the loft option to connect both together.
- Now I will re-import the design on the top face of the loft object.
- Now I will use extrude remove to create the Logo from the top view.
- Now I can Add some touches to the top.
- Now I will scale the design to a smaller size to save material.
- Now I will move to slice the object using the PROCUSINI Slicer.
RAW FILE
Each file contains (STL ,STEP ,and IGES) Format.
Slicer
As for the slicer for this printer its not for free as you have to create account on their website to access using the serial number of the printer.
- After Login to the slicer webpage we will have different options as the have already made abject {the user can just download and play around with}, and there is the option to slice 3D object and also to create molds from 3D object, In addition to some other paid features.
- Now I will choose 3D object and then I will insert my file for the settings.
-
I will start with a small version then if I want I can go with the full size.
-
Now I will press on continue and check the needed settings for my chocolate.
-
I will go with the predefined settings for chocolate.
-
Then I will press continue and download my file to be sent to printer.
- Now I will put the file on the SD card and sent it to the printer.
Printing
I will use the Procusini 5.0 machine which is not listed on the company site any more.
Technical details
-
The bed size is (150 X 250 X 100 mm)
-
The Nozzle is 1.0 mm and another one 1.2 mm but for me I will use the 1.0 mm
- Procusini machines in 2024
This is from the archive of the internet
The printer is so easy to use as I have just to insert the cartridge then the machine will preheat the material for 15 min (Honestly it took more I think this is depending on the material temperature as I was in a cold room), Then after the preheating I will need to choose the file I need to print and then I have to calibrate the extrusion of the material until its continuously coming out from the nozzle then the machine will calibrate the Z-axis using a sensor preinstalled on the machine.
Now I need to fill the cartridge
- I need to prepare the choco first to be then inserted in the cartridge.
- Then I need to cut its plastic head and insert it in the stainless steel cartridge.
- Now filling the cartridge.
- Then I will only need to get the cartridge back to place and close the lid.
- Now I’m ready to print i just need to insert the SD card containing the design and start the printing process.
Now this machine is using prepared CHOCO from the company which made exactly for this type of machines.
It works just by heating this chocolate until its soft enough to be extruded from the 1 mm nozzle then a bar from the top will push the material through the nozzle.
So this machine work exactly the same way normal 3D printers works just different material and different resolution.
- Now after inserting the material the printer will need to re-heat the material for 15 min.
- Then The machine will ask the user to move the nob until the extraction of the chocolate is continuous from the Nozzle.
The Nozzle is 1mm which means small objects are not gonna be printed (My first fail try).
- Unfortunately this try was not a success due to the small size of the print.
-
So I decided to re-print it and choosing the size to be around 5cm in diameter.
-
Alhamdollelah it was a successful try but I did not like the output details ( I think this is normal due to the large layer thickness).
- I will Now try to print it in full scale.
Reflection
The printing process is quite easy but its a bit different from printing using PLA or other materials like these; Food is a bit harder to deal with specially someone may needs to try what you have made, and having a big nozzle (1mm) is a bit tough as the layer thickness is big so the details are not gonna be the best when we want to build small objects but alhamdollelah it went well.
