6. 3D Scanning and printing¶

In this week task I had to reach the following:

Test the design rules for our printers.
Design and 3D print an object (small, few cm3, limited by printer time) that could not be easily made subtractively.
3D scan an object.

3D Design/Printing.¶

For the 3D design, I had to Design something that cannot be easily subtractively. So I thought of making a cube with a sphere inside of it that cannot be taken out.

First I started with designing it on fusion 360, I started with a 2D design of a rectangle with 50 mm sides.

Then I extruded the rectangle with 50mm height to form a cube.

Then using the hole function, I created the cylindrical holes through the 6 faces of the cube.

Lastly, I created the sphere inside the cube with 43mm diameter.

Then I was done with the design part, I exported the file as stl then prepared the model for printing by using cura software.

I chose ultimaker 3 extended as my printer, using support from the same Nozzle (PLA) because I have over hanged parts , and the brim to help in bed adhesion and to prevent warping and stabilize the model while printing, also I chose 0.4 nozzle, and because the model does not have fine details and the print is only for test experimental purposes and the strength of the model is not a big concern I chose 20% infill to reduce material consumption and time with 0.2 layers height. the job took almost 3 hours the model to be printed and it looked like this:

3D scanning¶

For the 3D scanning part, I chose and Iphone App called Qlone, that required an AR mat to be placed underneath the object to be scanned. The mat with the black and white chalkboard pattern serves as a tracking marker for the software. I chose my 9V battery to scan.

At the point when the object is set on the mat and the application is at use, An AR arch is set on the middle. The vault here means that the catching system. The article filtered necessities to squeeze into the arch.
