Color: Ruby Red
I’m really impressed with this FlashForge PLA filament in red. The color is vibrant and consistent, and it prints beautifully. I had excellent layer adhesion, smooth surfaces, and no issues with clogging or tangling. It fed evenly through my printer and held detail very well, even on longer prints. This filament made my prints come out clean and professional-looking right off the bed. I’ll definitely be buying this again and recommend it to anyone looking for reliable PLA with great color quality.

Firstly, I’d like to mention I’ve tried many different filaments and this black one by far has been the best. The quality is top tier in my opinion, there’s no issues during printing process and no tangles in the nozzle or the design you’re printing. Pricing for the amount is great and sometimes there are deals that are well worth it. The printing process is great but more importantly how the design is while clean it off the branches is also where it matters and I haven’t had any issues especially with this cat skull the nitty parts were easy to clean up. Over all, performance of this color is immaculate and will order more when needed.

This is the most true-to-expectation color of deep red filament that I have purchased, over the course of years and after purchasing from a large number of sellers and filament manufacturers. Though we use many filaments - Flashforge Rapid Ruby Red is ALWAYS an easy choice and convinced me to seek other Flashforge filaments whenever they are available.

The ruby red color on this PLA is deep and vibrant. It really stands out and gives prints a bold, clean look. I definitely enjoyed printing with this color it has a rich tone that looks even better in person. The filament arrived neatly wound, which I always appreciate. I did notice that this particular roll had a slight tendency to tangle occasionally, but nothing major or unmanageable. It never caused a serious issue, just something to keep an eye on during longer prints. I did have to spend a little time dialing in temperature and speed settings to get the best quality results. Once tuned properly, though, it produced very nice prints. A few calibration prints were all it took to get everything running smoothly. Overall, a solid filament with excellent color payoff. With a bit of fine-tuning, it delivers great results.

When it prints, it prints beautifully. Using a 0.25mm nozzle on my Flashforge Adventurer 5M, I’ve been able to get smooth, detailed prints with minimal stringing and no extrusion issues. Bed adhesion is also solid—sticks right to a heated bed without glue or tape. Filament diameter is spot-on, and I’ve been running it at 220°C with no problem, right in line with Flashforge’s recommended settings. Most prints come out strong, though I’ve seen some delamination—possibly due to thin walls or minor print setting issues. Now, the downside: about 40% of my spools have had mid-roll tangles. That’s a killer. Clean spool winding is crucial, and even though they look tightly wound, a few crossovers mid-print have forced restarts and wasted time. Packaging is excellent (vacuum-sealed with desiccant), and overall, the filament is good if you don’t hit a tangle. At this price point, it’s still competitive—but be ready to babysit your prints if you’re running a long job.
