Shattered Faceted Light

20150726 Faceted Light

As featured on Pinshape’s ‘Pick of the Week

You may have already seen, or even downloaded, my Lightbulb Lampshade which I created a while ago to give a new lease of life to an old Ikea lamp. Now I’ve create a new version to fit the competition criteria of the latest Pinshape Design Competition for a low-poly design. Of course this means you can also download the file for yourself completely free, just click here to download from Pinshape, or here for Thingiverse 🙂

20150726_143212The model was printed on an Up! Plus 2 3D printer, using the 0.2mm layer thickness and minimal support material. As you can see in the image to the left, there really was only a small amount of support material generated in the middle to support the top section, and this broke away very easily. You can also see a small break near the bottom where the printer must’ve bumped the model as it was printing, but thankfully it kept printing. Overall it took about 4 hours to print. If you’re planning on making one, the minimum diameter inside the design to fit over your light fixture and light-bulb is 31mm – if you need it larger, just scale up the design before printing.

Faceted Development

Above you can see the process of creating the 3D CAD model, this time challenging myself to use Rhino for the complete development rather than my usual Solidworks. This was to create the more complex form in a shorter amount of time. From left to right the process was:

  1. Use Revolve to create the light-bulb form.
  2. Convert this to a Mesh.
  3. Reduce Mesh to create the faceted effect.
  4. Use the Line tool to connect the points of the faceted mesh.
  5. Use the Pipe tool to add thickness to the lines.
  6. Add some solid sections to fill in some of the gaps, then Join all the pieces into a single mesh ready to export to STL.

If you make one please share your photos back on Pinshape or Thingiverse so I can check it out!

Let There Be Light

2015-01-26 Lightbulb LampMy first free giveaway for the new year! Click here to download the file ready to 3D print from Thingiverse.

I literally had an old Ikea lamp in my hands ready to throw away when I realised I could give it a whole new life with the help of 3D printing. My only real restriction was the volume of the Up! Plus 2 printer I’m using. You can see the original Ikea lamp in the images above, and process of transformation into something with (I think) much more personality. Projects like this are extremely satisfying as I hate to throw things away, and really demonstrates the opportunities to extend product longevity through 3D printing.

I’ve also taken some photos of the printing process so you can see the support material required. I knew this would be a bit painful and increase the print time, but while it looks like a lot the support is so thin that it really wasn’t too wasteful. I also have a feeling that there may be less support if I printed it upside down. If I need another one I’ll definitely try it out.

2015-01-26 Lamp TimelapseIf you make one I’d love to hear how it went and if you manage to print with less support. Just leave a comment here or through Thingiverse (along with photos). Happy printing!
