For personal usage, indoor, I'm doing some experiments with following lamp (v0.1):
Lamp is a led bulb enclosed in a methacrylate tube and with a 3D printed finish at the top using PLA (my first 3d print ;-).
In some www pages (by example, here) I've read that the led buld radiator can reach 90º C. Experimentally, the methacrylate and the PLA feels only slightly hot, I suppose around 40ºC.
According to www info, PLA has a melting point of 150ºC, far from this usage, but a continuous operative temperature of only 40ºC ( !? this made 3d printing unable in a country as my own one, where ambient in summer is around 40ºC).
So, my question, is PLA a valid material for this application? If not, some other one better?
Thanks a lot.
