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