Hi everybody,
A file to be processed with openjscad.
https://openjscad.org/
The aim is to provide a parametric lens file enabling the printing of optical element by FDM.
Salt annealing method was performed as described
https://www.thingiverse.com/thing:4675096
At 185°C for 1 hour.
As already mentionned the relatively bad precision of m3d printer does not allow to get a bubble free environment when printing.
It is transparent and free of salt frost effect but the bubbles inside affects the lens...
Maybe some will be more successful
Best Regards
