OVV3D PLA Filament 1.75mm, Silk PLA Dual Color 3D Printer Filament, Blue Red Coextrusion Filament, Color Change Every Inch Filament 3D Printing Materials +/-0.02mm, 1kg/2.2lb

Update (original review below). Manufacturer reached out to me after my review and discussed what printing settings I had tried. After some troubleshooting, they agreed to send me a new roll to try. The new roll arrived quickly and after a bit of fiddling I managed to get two great prints out of the new roll. I will say that the filament was a bit more finicky than normal PLA but once I got the settings right it looks great. I attached two pictures above, one showing the quality of prints of an octopus. The initial roll is in front and the completed print is in the background and the second picture. I highly recommend this filament and would not hesitate to buy it again despite the initial issues due to the manufacturer's excellent customer service.I will start off by saying that this filament looks great based on the layers that I could get to print properly. That being said, getting this to print without adhesion and clogging has been impossible for me with various settings. Adhesion to the bed seems great and the first few layers print very well. After a few layers though it seems like the filament begins to clog the nozzle and then skips layers, eventually ceasing to print entirely. I have tried adjusting temperature upward in increments and also slowed down the print speed, but I cannot get good layers. I also hear a popping noise from the nozzle which makes me think that the filament might contain excess moisture. I have tried the exact same file with both normal PLA and PETG and it prints fine which seems to indicate that the culprit is this filament. If you can get this to print successfully I think it would look fantastic, but I have not been successful so far.

The filament itself is very nice and prints great. My only complaint is that the color transitions could still be smoother. However given the quality and finish on the prints I still give it 5 stars

Prints well, came sealed and dried. With thin layers, the colors blend into a pretty rainbow on the edges of prints!For passing 0.35mm tolerance tests on my direct drive Ender 3, here's my cura settings:Layer Height: 0.16mmLine Width: 0.4mmWall Lines: 3Outer Wall Wipe Distance: 0.5mmWall ordering: Outside to InsideHorizontal Expansion: -0.03mmInitial Layer Expansion: -0.1mmHole Expansion: 0mmTop/Bottom Layers: 7Print Temp: 205cBed Temp: 40c (not sure if heating is even necessary)Flow: 98% (adjust for your printer)Print Speed: 60mm/sCoasting Volume: 0.02mm& Adjust retraction for your printer.

Tip: Always dry your filament before using!My full review is listed under the pros and cons.Pros:- Great adhesion- Interesting color effects- Very shiny- Easy to print- Spools nicely woundCons:- Colors not as advertised- Occasional gaps in prints- Occasional color shifts- Pricey compared to other filaments--Print quality--I printed these sample spools on my Prusa Mini+ with a PEI bed and the adhesion was great. I printed at 220C with the default settings in PrusaSlicer and the prints came out very shiny with little to no stringing (after drying). The spools are wound very nicely (better than Atomic Filaments, but not quite as perfectly as Prusament), but they don't fit on the spool holder that came with my printer. I ended up laying the spool flat and the printer had no problem pulling filament without tangling.I did hear quite a few popping noises while printing, and upon inspection I found some gaps in my prints. I do expect pops with wet filament, but I dried it down to 14% humidity so I don't see why it would still be wet. The gaps weren't very noticeable in my prints, but this could be a concern for you if you're looking for perfection.One of my prints had a few layers where the colors moved--ie, if red was on top, it switched to yellow for a few layers, then went back to red. This disrupted the rainbow effect on the print, but thankfully it only lasted for a few layers. I didn't expect this due to how nicely the spool was wound, so I'm not sure what happened there. Again, this might be an issue for you if you're looking for perfection, but it didn't bother me too much.--Colors--My biggest gripe is with the colors. They're darker than what's advertised. I have no doubt that the colors are stunning in bright, natural light, but they simply aren't the same as what you see in the pictures, regardless of how your monitor is calibrated. The colors look much darker when viewed in indoor light (even when it's bright/by a window), and some of the colors look muddy, especially the tricolors. The dual colors look pretty good, but they're still dark. If you're expecting to receive the exact colors listed in the photo, look elsewhere. But if you don't mind darker shades, this might be perfect for you.--Value--I bought this at $35 for 4x200g of filament. That's $0.044 per gram. Prusament is $30 for 1kg, or $0.03 per gram. Atomic Filament is $30-$35 for 1kg, or $0.03-0.035 per gram. As you can see, this filament is more expensive than both of those high-quality filaments. I'd say that the OVV3D filament is good, but Atomic and Prusament are great, so in the future I'd rather buy from them than get another sample pack from this brand. The benefit of buying this particular pack is that you get four colors instead of one, which is why I bought it in the first place. I wanted to try a few different colors before committing to a full spool. I'm glad I did so, because the colors aren't what I need for bigger projects, and I don't plan on buying them again.All in all, a good printing experience, but not my favorite final result.

I've managed to go through almost the enire roll in two days! It's pretty, prints well, and I've no issues with failed prints on my Bambu A1. I set the bed to 60° and the max nozle to 220°, which is what's printed on the spool.I think this is going to become one of my go-to filaments. It's a good all-purpose filament, with a little pizzaz. I also like the spool, it's sturdy, while being cardboard.

Absolutely beautiful color changes.
