OVV3D PLA Filament 1.75mm

Prints well, and looks fantastic. The color change is a feature that sets it apart from others as it isn't a clean sharp gradient of one color to the next. There is a bit of color shift too and from the previous colors that then changes to the next shade and so on. Very cool!

This product has the worst adhesion no matter how fast or slow, whether I use adhesion products or use different bed products to help adhesion. Have used 1/3 of the role with different tip temps, different tips, different bed materials and adhesion products to help maintain adhesion. Have printed with brims, with other bed adhesion options in slicer to nearly absolutely no avail whatsoever. Product looks good in bag, looks good on roll, but the product right out of bag and after drying has helped zero for bed adhesion. I’ve used pei, hei, glass, painters tape, hair spray, and glue sticks. Absolutely closest to zero adhesion. I’ve used hundreds upon hundreds of different materials on my printer and have had more issues and problems with this filament than I ever had with carbon fiber materials. Terrible quality for printing. Again, color looks great on roll, had extremely high hopes with some of the positive reviews I’ve read. A yet had absolutely zero luck. The roll is back in bag, and is on the rack for “never buy again” materials.

I really wanted to love this filament. However half of my prints so far have broken coming off of the bed. I even added an extra wall layer and doubled my normal infill percentage to use this filament after the first print broke. To be clear my bed is leveled well and I get proper adhesion (not too stuck and not coming loose) with other brands. I haven't had any other prints break coming off the bed. These prints also snap across layer lines seemingly implying that the filament isn't adhering to itself well. I've added images of the bubbles and breaks. This filament also leaves really harsh layer lines compared to almost every other filament in my collection. I also dry my filaments before use, and they sit in a sealed box (minus the small gasket hole to get the filament to the printer) with plenty of desiccant during the printing process, so I don't believe moisture is an issue. Unless I got a bad batch somehow I really cannot recommend this filament.I really love the gorgeous colors and gradual change of this filament, but I'm getting really sick of reinforcing and gluing prints back together. These prints are also successful with every other filament I own both at the same settings and with my normal wall and infill settings.Again, stunning and fun colors, but I'm incredibly unhappy with the defects that come out when using this filament. If you don't mind really increasing your wall layers and infill percentage... and you don't mind having small bubbles periodically in your print then this could still be a good option I suppose. I only gave it two stars because it didn't clog my nozzle like many cheap filaments do, and it also really is a pretty gradual rainbow shift.

I love it, printed some "crocheted" pokemon with it, recommended speeds are like 50mm/s but I've been running at 150 and this kept up great. Only criticism I have with rainbow filaments is I wish theyd switch colors more often. They go through about a figure a color and I don't like changing large full day prints so I'll never see the full effect

Overall this looks nice but it doesnt fit in the AMS as its slightly too big so making rings for it isn't an option. The color chnage is the slowest of any filament Ive ever used and while the colors are pretty you dont cycle all the colors in almost 100g of filament so unless it for something huge you wont get most of the colors. Its a matte filament so its inherently weaker than normal PLA or PLA+ and no stronger or weaker than any silk or matte PLA I have used from other companies.I found 230c was too hot for a Bambu and resulted in causing stringing and slight deformation on points but lowering the temp solved it.

I like this material for it's print quality, I've had pieces turn out looking very close to smooth, however be careful removing any supports. When removing supports I try to crack them first with pliers to make weak spots, or when possible, cut them instead of just pulling. My latest piece was destroyed when I tried to crack a support, and the part itself cracked with it. At that point I figured it was already ruined, so I thought I'd use that part as a test piece for how brittle the material is and found that I could crack the part to pieces with ease (I did use lightning infill).I'm not saying not to buy this material, just know it's cons before buying.My suggestion, don't print small parts on your pieces with this material, and use an infill pattern that's strong.tldr: If you want a pretty, colorful material, and aren't bothered by brittle material, then this prints amazing.

Originally wanted to give this pla a great review but after printing multiple prints it just keeps getting worse. It's starting to not stick to my PEI plate. I have cleaned the plate and adjusted temperature multiple times to no avail. Also getting a lot of bubbles and even with more walls and infill the prints are brittle. It has great color, but the color transition takes way too long.

Nice color but spool was tangled throughout the whole roll. Not sure if was a return or something but it looked like someone hand rolled the entire spool and had feed issues because of it.Update: Received a replacement spool that was much better than the first and had no issues feeding this time around.
