Tasks for a Week

Group Assignment

For group assignment, we are using .STL file which we found from Test your 3D printer! v2. The file is challenging because of its tiny size. If follows the instruction the result will come out in just 30 minutes. The file helps to check the machine calibration and it test how much precise the machine is. We have to check these parameters:


File from thingiverse

In FabLab Khairpur we have Ultimaker 2+, Ultimaker Extended 2+ and last but not least our simplest and favourite 3D-printer Prusa i3, we use all of them to print different parts in this week.

Result from Prusa i3


Result from Ultimaker 2+

In both machines we set infill to 35 %, layer height to 0.1mm and set raft the results shows that Ultimaker 2+ extended work better than prusa i3. But here prusa i3 results dosen't show its full potential as it is not perfectily calibrated like Ultimaker 2+ Extended.

Learning Outcomes

Individual Assignment

3D Modeling

Working on 3-D Printer is not new for me, but 3-D Modeling is new and yet-challenging. I start to work on SolidWorks in this course and I learned of it, but still when I try to make something in it I learn more techniques to work on this software. My first individual task of the week is to design and 3D print an object (small, few cm), that could not be made subtractively. I replicate a handsfree holder from thingiverse Earbud holder by sneakypoo. It was looking easy in starting but to get it out from subtractive manufacturing it becomes complicate for me to design. I didn't get the exact copy, but I learned new techniques and solve many design challenges which I faced in this project.

The holder is consist of 3 parts in which one is core body and 2 covers (Left and Right). I decided to make core and left cover and then mirror the left part to get right cover. After making parts I assembled them in Assembly file to check either my parts fit perfectily or not (I did mess 2 times in calculation, the printed results are miss calculated). I mentioned the steps with pictures below:

Designing Core (internal part):

Designing Cover (external parts):

Designing Additive Model:

It is difficult to made above project in subtractive manufacturing but it is possible. So I decided to make 1 more project for this week. I made some 2 3D hollow shapes Cube and Paramid and connect them in chain form, which cannot be made subtractively, because if we make them in subtractive wy how we suppose to join them within each other

3D Scanning

I never n.use Kinect before like this, its a completely new and interesting experice to scan ourself. For this we download "KinectDeveloperToolkit-v1.7.0-Setup", "KinectSDK-v1.7-Setup" and "Skanect-1.9.0-win64" after downloading them we start Kinect and we follow these steps:
