{0.4} 3D Printed Hollow Form Object



 Using my previous concepts I decided to use the rain lamp inspired design as it had the best balance of complexity and simplicity, and well, its the one I liked the most. It doesn't have much of a purpose expect looking cool.

Taking in the feedback from fellow classmates, I started work on making my final and printable version of my hollow object, first starting with what was mentioned the most from my classmates, the overhang on the top and bottom bases, then remaking the wires to be bigger to make them less fragile.


We left off with the rain lamp looking like the photo to the left of this text. Now, there is many issues with this design that needed to be modified, especially the top and bottom bases, the over hang was 90 degrees and would not be good to print on the school 3d printer or the one I have at home, so I started by remaking the bottom, simply connecting the top section to the bottom to make a more printable angle, as seen bellow. After fixing the bottom I used the curve command to make the top pointed and fileting the edge to soften the sharp edge and modified the bottom again to be steeper to make it easier for the printer to print.

                                           

Before re adding the wires, I decided to replace the simple spiral in the middle with more wires, but this time, the wires would twist another direction to create a cool effect when looking at the object.

                                   

And that is it, that is all I did to  make this printable. admittedly, I thought this would be the first prototype of many, I was sure the floor on the base before the wire would fail and I would have to modify it further before it could ever print, my dad and I thought there was only a 10% chance this would successfully print it, but to our surprise it printed just fine! so we made the wires thinner, trying to make our printer fail, but it still printed!

But there are many things to keep in mind with this prototype:

1. My printer is a Creality KC1 High speed 3D printer, it is able to print details and difficult parts and overhangs better than the schools printer, so though the print is possible on my personal 3D printer, it admittedly may not print on the schools printers, it was enough of a miracle that my printer was able to print it in the first place

2. I used a 0.4mm nozzle for this prototype, since that is all I had at home, so the walls are closer to 0.4mm thick instead of 0.2mm

3. Since my printer is a Creality printer, I had to use the Creality slicer, as shown bellow






I also sliced the object in Prusa with the same settings as the ones I used in Creality (besides the nozzle size and therefore the wall size) and will list them below:

  • Size of the object (in mm): 73.15 x 73.15 x 180
  • Used 7 Top Solid Layers (to give the base top floor the best chance of surviving) and 4 bottom layers
  • Double perimeter
  • Non-spiral tool path

In the end, I am happy and how this turned out, and really hope it will still print on the school printer.
