Goto GuardSilk Rainbow PLA Filament, Silk PLA Multicolor Filament Color Changing with Green Blue Purple Pink Yellow PLA, 3D Printing Filament 1.75mm 3D Filament 1kg

love the bright colors and its amazing to work with.. will purchase again for sure........

I do a lot of 3d printing and have a ton of filament. I just throw a decadent into one of the bags with my 3d filament, seal the bag, and pump out all the air. Super easy and works great. Love this and definitely this to all of you hobbyists out there.

The media could not be loaded. I've reviewed quite a few of these dual color silks, and this one is as good as the others, including at high speeds like 300 mm/s. The only difference is the viscosity, which seems to be higher than most of the others. It didn't affect the print, it just had me a little confused while I was loading the filament, as the filament extrudes very thick when purging. However, as I said, it doesn't affect the print at all.Using my K1 Max, I printed with the following settings:Nozzle: 0.40mm @ 225°CBed: 60°C for the first layer, 50°C for all other layersCooling: 75-100%Speed: 300mm/s (actual is limited by head movements)Brim for adhesion (this cat typically requires a brim to print)I used glue stick on the bed with a brim and didn't run into any adhesion issues. The print is very strong and looks really nice. I really like the Red & Blue mix. If you like the look, I can recommend the filament.For those who are new to silks, you might want to experiment a bit before committing to a full print, as silks can take a little getting used to. However, this filament is pretty forgiving. BEST!

I know some people have complained about this filament, and honestly I do not understand why. This worked great for me on the very first print I did with it. An articulated tooth blade dragon from maker world. I think a lot of people dont understand that calibration of new filaments from new/unknown brands is a MUST! I did both Flow Rate and Flow Dynamics calibration with Bambu studio and my P1S, and the print turned out excellent, just as expected after calibration. Also, you MUST listen and READ when the manufacture says the speed limit is 180mm/s! I printed at 220C/55C and 180mm/s with it being calibrated as well and it turned out amazing, imagine that! Funny how things work out when you read and understand instructions and use best practices when it comes to new filaments. If you cant get this to work then its user error plain and simple. I will say the cardboard spool was slightly dented but it did not impact its ability to be used in the Bambu AMS system, it worked perfectly in mine. I do also think that they should make sure the label on the spool matches what the listing claims, as far as extruder temp, as the spool says 210C but listing says 220C. That said, 220C worked perfect for me so no big deal. Overall im giving 5 stars because the filament printed perfectly as it should, within the parameters they gave. This isnt Bambu PLA Basic, you need to calibrate and speed limit!

They had a few bed adhesion issues that sorted out give that a 7/10, overall quality 5/10 . About 800 g into the filament and all of a sudden the filament was no longer feeding through my extruder and it turns out that the diameter of the filament was 1.2 instead of 1.75. 2/10The whole rest of the roll is trash.

The Goto Guard silk PLA prints smoothly with no jams or clogs. Color is vibrant and has a nice transition. Zero issues with bed or layer adhesion.The spool is neatly wound without any tangles.I normally dry silk PLA for at least 5 hours before use, but I printed this one straight from the bag without any issues.A note for those new to 3d printing (and something I wish I knew): silk PLA can be trickier than standard PLA. Temperature, speed and retraction settings need to be dialed in for best performance and will vary from normal PLA. Older and/or less tuned machines may have trouble achieving a good print, but proper calibration will make a world of difference.

This is some of the prettier silk rainbow filament I have had and prints quite nicely. It came well sealed and printed without any problems and without needing to be dried. It came on a cardboard spool that worked well enough and didn't seem to have any major "shedding" issues, but I still prefer plastic spools for reliability. For testing I decided to try printing a medium size bowl and a 150% scale Benchy, as the larger sizes allow for a bit of color change to be apparent in the print. The bowl was printed at 300mm/s and slightly hotter than recommended (220C), which I typically do when aiming for higher speeds. While it came out ok, it did suffer from a bit of non-uniformity and the layer lines were more visible than I like. Essentially, it was pretty obvious that I was printing this at a higher speed than it really likes. So, for my second test (the Benchy) I lowered the speed just a bit down to 250mm/s and the print quality improved drastically, as you can tell from the pictures. The resulting big Benchy was almost flawless and the shine and color shifts were excellent. Doing a bit more investigation and some manual feeding of the filament, I was able to tell that this filament is the type of silk that almost balloons when it exits the nozzle and expands to 2x-3x its original diameter when not pressed up against the build plate. This is fairly common with a lot of silks I have run across, is not necessarily an issue, and doesn't usually affect print quality except in one respect: filaments that behave this way typically do not print that well at really high speeds, topping out at between 200-250mm/s. As they clearly state in the description pictures that the recommended print speed is 30-180mm/s, I don't hold this against them at all.So, this filament is quite pretty and prints well, as long as you keep your speeds a reasonable rate. My only criticism would be that, even for silk rainbow PLA, it seems to be a bit higher priced than I generally would expect.
