I've taken on the challenge of trying to print something which is clear but only had minimal success. I know that it won't be 100% clear but I have read reviews saying that it's possible to get it to be around 90% which is acceptable. The best results so far have been with PETG & PCTG. A 1.5MM nozzle was used but the print quality was unacceptable. The larger the layer height the clearer it gets but it loses layer adhesion once the layers are too thick. My standard 0.4 MM nozzle prints with great layer adhesion but the filament looks like a frosty white or off white. To sum it up, clear filament being extruded needs to be as thick as possible to remain clear but lacks layer adhesion & print quality. I'm trying to find the perfect balance of layer adhesion, transparency, and print quality. Could anybody recommend the correct nozzle size & slicer settings?
