Need a clear filament for reproduction of a old search light "lens" on a boat. Hopeful just like a glass pane on a window......is something like that available or maybe close to it???

    I stumbled over this some time ago:



    But getting something really transparent will be difficult. Could be something like an acrylic sheet and just a printed mounting bracket an alternative?


    @geert_2 posted some transparent parts some time ago, maybe he can help you :).

    This is the maximum I ever got. From my tests: print as slow as possible, as cool as possible, and in as thin layers as possible. The best here is 0.06mm layers, 10mm/s speed, and around 200...210°C. This is transparent PET (brand no longer available). Top row 50mm/s, bottom row 10mm/s; layer-height from left to right (mm): 0.4; 0.3; 0.2; 0.1; 0.06. Blocks are (in mm): 20 x 10 x 10, with my hollow watermark sitting halfway.


    Do similar small tests to dial-in optimal settings for your system and material.


    Sanding, polishing, or chemically smoothing with dichloromethane may be required to reduce layer lines. Otherwise they act as separate little lenses, destroying the clarity.


    Another option might be to make a mould, polish that, and cast some clear epoxy in it. This will give far better results. Or print an "original" in non-transparent material, polish that very well, make a silicone mould around it, and use that to cast the epoxy. If you need the light shining through, like in car rear lights, 3D-printing might be good enough. If you need a clear lens and a beam of light, like in car headlights, you will need to cast.


    The testsamples:





    The best: 0.06mm, 10mm/s, 200...210°C:



    Left one is the best as printed, right one is after some sanding and polishing, so the outer layer-lines got removed. Inner artifacts caused by entrapped air are obviously not removed. Text is 3.5mm high, text-legs are 0.5mm.



    One part is as printed, the other chemically smoothed with dichloromethane. This is PET too:

    Thanks for the epoxy tip with mold making .......will keep it in mind sounds like a solid method to get what's needed......


      already bought the TC Clear ......checking several different sources, let's about 90% of the light through.......the rest fog like
