3D Scanning and Printing

For this assignment I have to design and 3D print something from scratch, then scan and print another thing.

I decided to design and build something funtional and usefull for my final project and it is a "ballcaster" which is a support point for differential traction used in mobile robots.

The process begins designing with Autodesk invertor.

Once you finish your design you have to export it into STL format in order to get ready to use the 3D printing software.

The printer used for this assignment is a Felix2.0 and the software is Repetier, it's a open software and the good part is that you can manipulate all the variables of the process, that allows you experiment in a better way

You can download Repetier for felix here.

OK, once you have the STL file open it with repetier

Before printing you have to select a profile for slicing and then press the "Slice with SFACT". In this case I selected "1.1Draft Quality-no support" profile.

Once the slicing process have been done the next step is to prepare the printer, I used the following parameters for PLA:

-extruder temperature: 210 ° C

-bed temperature: 60 ° C

Then click "Print" :)

And at the same time:

After many layer:

I had to iterate 3 time until get the correct size and tolerances

Finally is only needed a marble of 15 mm diameter to complete the ballcaster!.

For scanning I decided to scan myself using the 123d cutch software which allows you to scan from pictures of a object. So I take pictures in 360°(with help of my friend) and then generated the 3D model with the software

Then you can use 3ds max in order to clean and add something like a pedestal

Then, following the same process described above we can 3D-print. This time I selected the "2.4 normal quality full suport+raft" profile because the 3D-model needs supports for a well print and a raft to avoid the takeoff from the hot bed.
