3D Scanning and Printing
Assignments:
Group assignment:
⚡Test the design rules for your 3D printer(s)
⚡Document your work on the group work page and reflect on your individual page what you learned about characteristics of your printer(s)
Individual assignment:
⚡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)
During this week (#5), we experimented with 3D printing technology, specifically Fused Deposition Modeling (FDM), which uses plastic filament to create 3D objects. As Group assigment we have to test the design rules for your 3D printer and the task this week that could not be easily made subtractively so at first, I download one and then I designed one. I download a piece from Thingiverse,an online 3D design library and then the piece were printed in a FlashForge Dream 3D Printer located in the CIDI FAB LAB
To print something, werever the machine you use, alway you have to checkout this things
Machine things
| Type / Model of the 3D printer | Dreamer / Flashforge |
| Type of filament | PLA (Polytactic Acid) |
| Bed Temperature / filament Temperature | With PLA THE bed temperature is around 50 °C, but whit PLA print temperature is around 210 °C |
| Printing speed | The regular is about 50–60 mm/s, but users should note that some materials can be printed very quickly while some require a slower rate to prevent warping or print failure |
| Infill | Its refers to the internal patterns that are inside most 3D printed parts |
| Model first layer: | It forms the foundation on which more plastic is to be laid |
Test 1/ Small object that could not be easily made subtractively
Components you need
- 3D printer - Flashforge Dreamer
- PLA filament
- STL File
- Ultimaker Cura
Comments
My experience with the Flashforge was good (I think), Ive already know a little about 3D printers, the thing that I didn't know about this machine (the Flashforge) was the way to bring files...I mean the use of G code format
3D Scanning
Test 1/ Scan an object with my cellphone
To make that test I downloaded a software from the App Store
During this week (#5), we also experimented with 3D Scanning technology, in this case, I've used an App called Polycam to generate the 3D file. That file was GLTF (the extension) allowed for free version users.
Components you need
- 3D printer - Flashforge Dreamer
- PLA filament
- STL File
- Autodesk Meshmixer/ Blender
- Ultimaker Cura
1 - Polycam + Meshmixer
2- Printing
Conclusions: As final thoughts and discoveries I can mention the facilities provided by MESHMIXER to mold the previously scanned part.
The settings for printing the scanned was done in REPETIER HOST, where:
- The bed temperature was 60%.
- Use a sealant to prevent the part from peeling off the bed during printing of the initial base.
- The printing was done with INFILL of 15%, because it did not require a lot of work to endure
- The quality of the print was STANDART, without supports.
Problems:My experience with the whole process of Scanning - Printing was very pleasend and long. The scanning thing I considered a bit imperfect cause I'd really depend of your expertise with the application (Polycam), its no that exact as a Platform of scanning would be. But it's okay to have a rapid model to test. Some software's (like Blender) I didn't know how to use it cause the interface was too much different of all else I knew, the different options and the way to use it it was too specific, and you need previous experience or YouTube videos to understands the things you are doing, to do it quickly.
Solutions: Read,try and search thats the correct sequence, also I'd used MESHMIXER to polish the imperfections of he scan
