5. 3D Printing and Scaning¶
Introduction to 3D Printing Week¶
Welcome to 3D Printing Week at Fab Academy! This week, we embarked on an exciting journey into the realm of additive manufacturing, exploring the capabilities of 3D printers and pushing the boundaries of creativity. Our hands-on activities included printing and testing various objects to understand the capabilities and limitations of our 3D printers. From prototyping functional parts to creating intricate designs, we delved into the world of layer-by-layer fabrication, honing our skills in design optimization and material selection.
In addition to printing, we ventured into the realm of 3D scanning, using cutting-edge technology to capture real-world objects in digital form. Through 3D scanning, we gained insights into the process of digitizing physical objects and learned how to manipulate and modify scanned data for further design and manufacturing purposes.
Let me share the reference links that I have used for this week, Hope it helps you as well!

Machine in Our Lab¶
The FractalWorks Julia Extended Machine is a powerful tool in our lab, specializing in the exploration of Julia sets, intricate fractal geometries. With advanced algorithms and computational abilities, it enables visualization and analysis of these mesmerizing structures, aiding our research in fractal geometry and mathematical principles.
Group Assignment¶
Tests for PLA¶
1.Angle Test¶
During this test, we utilized the angle test file to assess the capabilities of our printer. Our observations revealed that the printer performed satisfactorily up to angles of 40-45 degrees, after which stringing issues became apparent.
2.Thickness Test¶
In this test we saw how think of a wall can our 3D printer build and how thin of a slit can it build. We concluded that it can go upto 0.1mm is a bit not right but rest of them are fine.
3.Clearence test¶
A clearance of 0.1 mm allows the fuses to fit snugly with the shaft. With a clearance of 0.2 mm, there is movement, albeit with some friction, requiring a slight initial force. Clearances above 0.2 mm result in a looser fit and easy movement, accompanied by an increasing amount of sideways movement.
4.Bridge Test¶
It is being printed perfectly fine.
Tests for TPU¶
Bridge,Thickness,Angle Test with TPU¶
The Test was maybe successful cant say much because the TPU is a elastic material and rubbery in nature so there was a really heavy stringing in our Test prints for TPU.
3D Printing¶
The material that I have used for my 3D print is PLA. I have printed a retractable 3D printed sword. First I made the file for 3D printing in Fusion 360, I reffered to a video on youtube the link will be attached in the beigining of the page.
After making the file the next step was to set up the slicing software, The software we have used for slicing in Fractory which is a software that comes along with the printer itself.
After downloading the software I exported my file from fusion and opened it in the fractory software.
It Should About 9 hours for the print so I just left it overnight at my lab to print, and printed it without the supports!
Hero Shot¶
The last layer of the sword actually got fused with another layer so it made the sword shot but yes this week might be over but I will surely print more with making the spaces in between the layer bigger so that it does not fuse.
3D Scanning¶
For 3D Scanning for now I have only tried to scan my room with matterport here is the result
