Color: 1kg Silk Black
'A Good and Superb PLA!' Frankly Id heard many fine things and some favorable comment on SUNLU Filaments! So having bought a roll an done a project I can Honestly Report that most of the favorable things reported are in truth correct as it is a 'Very Fine' Plastic and SUNLU definitely has its act together!!!. PROS: Makes a Neat an Classy looking Part! Easy to Run, Easy to Set Up! Its the Real Deal You Get A Full Roll of !st Class Filament! Almost the Only Silk PLA Plus+ on the Market!!!!! A Real Bargain as the Price is Fantastic for what you get!. Fast Amazon Shipping cannot be Beat!!!!! CONS: None actually cept If Id known this was a PLA+ Id have ordered it sooner!!!!! In General: Now In My Useage The SUNLU worked and printed quite well. Setup was simple, I use Sticky Blue painters tape. Set Nozzle at 259 and Bed 109 and let warmup for 10-15 mins. I set 1st Layer at Nozzle 257 Bed 100, Speed at 35 or 40! Then after 1st layer is down and hard I set the rest of the run at about say: Nozzle 250- or 255 Bed 60 0r 75 and let Speed run at 45... True "I Know" at those settings Ill get some stringing but 'I dont have any problems with layers not bonding and It don't take 'All Day' to get the part finished either. Yes I know there are all kinds of 'Micro-settings, But I know that most machines have there own 'Pet Settings for wanting to run right. Now most folks want to run 'Cold and Fast' But I tried that and got a LOT of junk parts!. For me I found that "Slow but Hot" seems to get 'Better Parts'..... Me I adjust my speed with a New Plastic until Stringing starts to appear then I back off fast!. I also run my tests a 'Bit Differently' as many will run a ducky or a benchly and its a good way. For Myself I have a small but 'difficult part', See it dont take much Plastic but if the plastic is good enough to make a 'Difficult Part' then the easy stuff will run Home Free as the SUNLU did!!!!!!!!!! Now One Major Complaint w Sunlu is it doesnt extrude well or the teeth dont grip the Plastic right!. Yes at one time 'I Had' that issue but here is how I worked around it!. A HOT TIP: Now sooner or later when the teeth wear down you will have to replace that drive extruder gear!. On most new machines its the round Brass One w the two small allen nuts sticking out the top side! Most guys re install the gear wrong, I know I did?????? Yes I did as most of us will do what the YouTube guys did as they 'Set It' Plumb in the middle!. Hey if you are satisfied and it works for you go for it!!!!!!!!!! But there's a Better Way, In stead of in the Middle I just slid the Gear down a notch and let the plastic run off the teeth on the Top Side of the Gear as it grips better and runs smoother too. Oh yes it will surely wear like they all do in time, But if you did it right there is no great need to replace the gear not by any means sic!!!... Just loosen the allens then "CAREFULLY" slide the gear back upwards until the Teeth on the bottom which are still good are NOW gripping the plastic as I think its pretty neat to reuse and get good service from the same part twice!!!!!. TO: Close; SUNLU Silk PLA is super good stuff that is easy to set up, It runs fine and makes a good part!. And to Finish Its the only PLA+ that runs a silk fibre so it has Very Considerable strength and I definitely Intend to try some Printer Gears with this and the smooth finish makes a classy looking part too!. Kudos to the Seller! Kudos to Amazon! Nuff Said... IndianaED

Color: Glow in the Dark - Green to Glow Green
I was very surprised how glow in the dark this was as far as brightness and long lasting after being exposed to light. It is kinda of a default bright green when it's not glowing. I thought the default color would be closer to a white with a small green hint. It did perform well as a basic pla filament and didn't seem to have a lot of stringing at all. I want to try out the blue one next just to try it out. It gives me a lot of ideas where to use glowing objects. :)

Color: Bundle 4kg Silk Silver+black+red Copper+...
I find this brand, Sunlu, to be the top filament to use on my Bambu Lab A1 Mini. Every print has came out perfect. Never had any clogging, tangling or any other issues during printing. SUNLU is a trusted brand for my A1 Mini. I have tried other brands, but have had minor issues during printing. Most issues are tangling.

Color: Bundle Pla 16 Colors 4kg
I just got into 3D printing and got this as I saw and heard good things about this product on TikTok. You get an amazing variety of color for a good price. So far my prints have came out very nice and smooth, even when the printer had malfunctions. Personally I’ve had a good exprince with AMS as long as YOU manually enter it on AMS. It fits very small in the AMS so depending on yours it may or may not work. These filaments are a lot smaller and less than what you’d usually get so keep that in mind. There’s no way to take them off to move on another fillement holder. My only con would be how hard and tight the roll is, many times I have to give it slack every 30 mins to avoid it failing by either getting twisted or by being to tight to pull.

Reviewed in the United States on June 8, 2025 by Hi, go away
The filament is poorly wound in the spool and incredibly prone to tangling. I've had larger models (200g and up) consistently fail mid-print because the filament broke. (I have a direct drive extruder that can pull hard enough to break a tangled filament easily.) There's nothing more frustrating than having a print that takes 80 hours have the filament feeding it break at the 60 hour mark. The bed adhesion is good and the print quality is decent. But if you're doing any large print, this stuff is unusable. And if you're doing small prints, expect that periodically you're going to have to redo them due to a filament tangle that trashed the print in the middle. UPDATE: 8/6/2024: This stuff still sucks. About a week ago I saw Sunlu filament on sale again, and I thought that after a few years (and a number of printer modifications at my end), I'd give them another try. Sunlu seems to have solved some of their tangling problems, but the filament itself doesn't seem to hold consistent diameter, and it remains prone to jamming/clogging. Since my first review of this stuff a while back, I've added a runout detector that includes both switch and slotted optical wheel. And I've gone from my old control board to a Manta M8P running Kilpper and Mainsail, so I can fine-tune sensitivity to wheel motion for jam detection. That's what clued me in to the filament jamming the way that it did. I'm using Orca Slicer, and I did the temperature and flow rate calibrations for the filament, running it at about 98% flow and 210C extrusion with 70C bed temperature. Print speed is generally in the 30mm-50mm range, and even on a bed slinger, this is hardly pushing it. I don't make enough parts to want to drive the printer for speed, but I do require quality prints. So I err on the slow side. In any case, this stuff seriously jammed the extruder, and all indications are that this was a result of unevenness of filament diameter. Before I was done, I was replacing a heater block assembly to undo the damage done by this stuff. (The nozzle is probably a complete writeoff, but I keep plenty 0.4mm nozzles in stock. And some Saturday when I'm not too busy, I'll recover the block, the heater element, the thermocouple, and the copper sleeve that goes into the heatbreak by disassembling them, scraping off the molten plastic, and where appropriate soaking them in acetone.) Overall, though, this cheap filament was not worth all the problems it caused -- twice. And at this point Sunlu is on my list of filaments I'll never buy again. I regret having given them a second chance as I did.
