Hi Vylbird,

  1. The light was actually designed to block most of the direct light so that only reflected light would scatter. The light was inspired by the great designer Louis Poulsen and his amazing lighting diagrams and studies. Definitely worth research if you're interested.

  2. I wouldn't say most filaments are 'ridiculously' flammable otherwise they would catch fire as they are extruded. We recommend using a cfl bulb due to its lower temperature. A typical CFL bulb has a heat range around 80C-100C and that's at the surface of the bulb. ABS has a glass transition temp around 220C and an auto ignition temp closer to 400C. This provides a very safe buffer from the CFL bulb temp. Also PLA or ABS will no doubt catch fire in a flame which has a temp over 1000C but this only applies if you have a malfunctioning electrical connection (in which case most components in your house would also catch fire since almost every electrical component in a modern home is plastic and in direct connection with electrical circuits).

We leave our light on every night and I have been actively checking the temperature, by touch, and the light is only slightly warm to the touch.

The bigger worry is if you use an incandescent bulb or you have a light with very little ventilation. We designed an different light with no ventilation and used a 60 watt incandescent bulb. The result was the print slowly sagged over the course of 5 days and it would have fallen off if we didn't stop it (which was part of our small experiment).

As mentioned the light was designed so the fins would not allow light to pass through (creating the gradient effect) which is why it prints with 4 perimeters. We also printed it in carbon fiber which resulted in a very cool 'dark' effect. Great for an intimate setting.

Thanks for the feedback.

I like your wind turbine too. Can't wait to try printing it.
