First, thank you very much for the detailed replyâŚ
I have tried 11 different colors to this point, and although the 3 different colors used in the pics were new, vacuum-sealed, purchased within the last 4 weeks. Of course, I know that new to me, usually means just that, but not necessarily new to the world. But yes, I printed many models both before, and after various 50C - 8 hour dries (in my Comgrow Dryer from Amazon) on both the Black and the Brass filaments shown, as well as several others not pictured. The Bambu Green was not dried, and I printed 5 different models with it, there were zero issues in any.
I am currently testing Overture Turbo Black PLA (60-600 mm/s), which I ordered to test a theory that HS PLA (60-600 mm/s) may/might and/or possibly will work better than regular speed (30-80 mm/s) PLA on these upgraded/upscaled Bambu printers. I didnât choose Overture Turbo due to preference, but I have had good luck with Overture in general (much better luck with Duramic PLA+), on my SLOW SPEED Creality Bed Slingers. Admittedly, I have had no personal ideas or experiences with printing above 70 mm/s, with my normal being 60 mm/s (with my Ender 3 v2 Neo, upgraded with a Micro Swiss NG), so whether the TURBO, HS, or any other âTitledâ filaments, are different, or make a difference, is beyond my knowledge, but I thought it important to mention.
I have done only the 2 calibrations in Bambu Suite, on every filament. I am currently running the additional calibrations within Orca, starting with the Max Volumetric Speed test. As with each/every previous filament calibrated and tested, both during and after the calibrations, as well as the 40x60x4mm test piece (plus with all but 2 other filaments, I have additionally printed the boat benchy), so far this one also looks great. The failures have always started when I print the first model.
Itâs important to note, to eliminate thoughts that an issue may lurk within the design, the model prints well on my 2 Creality printers. The detail and quality standard I need them printed to, are beyond MY Crealityâs abilities. I use them for structural, and/or functional pieces when detail is not critical.
As to the prints not sticking to the build platesâŚFrom my personal experience (with my Crealitys), I have used Borosilicate Glass 60%, G10 30%, and Textured Flexible Magnetic 10%. I have only used adhesives for Glass, hairspray has always worked best for PLA, and purple glue stick for PETG. If/when I have used in reverse (hairspray for PETG, glue for PLA), I have had disastrous results when removing. For cleaning Glass (whether hairspray or glue is used), I just run water over it and rub the residue off with nitrile-gloved hands, then dawn liquid, on a microfiber rag, to remove anything left. For G10, the same, both are then dried with a separate microfiber rag. For Textured Magnetic, IPA on a microfiber rag between every print up to 4, then washed and dried the same as the others. All that said, that is just my experience with my Crealitys. I am not married this approach however, and I will certainly try the glue stick on this as well. The Brim was only tried a few times, since the first few attempts warped on the corners initially, but otherwise well stuck to the plate. Once the prints stopped sticking, I first tried Brims, with no luck, I began using hairspray, which worked for 2-3 prints. Eventually nothing worked, even when tried cleaning after every single attempt. I tried IPA, hairspray, Brims, hairspray plus Brims, no dice on anything. Eventually I had to stoop all the way down to using a Raft, and FINALLY got it to anchor. The Brim itself didnât look bad after cleaning it, but the Raft is a nightmare to get off. The Raft makes it extremely hard to even get it close to decent looking, even after sanding and light torching. The only solace to that, is that the back (build plate side) of the print is not seen. It only has to been flat and semi-smooth, looks donât matter as much, although I would far rather the back look good as well, since I do plan on selling them if I can get them looking good enough.
