Auto-generated from all reviews of this business. For reference only.I initially used sunlu filaments to save monay, years ago, but spool after spool i saw this company to grow and to improve quality every day! I now use only sunlu for tpu, pla+ and petg for my Ender 3. I appreciate very much the costant performances, best cost/quality ratio end also the possibility to buy on different channels at best price. Hope they will extend filament variety also with special materials, as for standard once the service Is very good.
SUNLU‘s Filament is the best,I use sunlu filament for 3 years！
Good prices, quality and quick delivery. That goes for both filaments and FilaDryer
Purchased an S4 dryer and bundle of 3 Kgs of filament. The dryer arrived a couple of days later, the filament was in the region of a week later. Dryer was faulty on arrival and I could hear a screw or two loose inside so I wanted to return/swap this unit. Contacted Sunlu on their email addresses, but understood they are in China so would have to wait until the next morning for a reply. They asked for a video of the issue which I sent and the same day they dispatched a new unit. That got to me before the filament arrived! Can't really fault them for response or service - it was excellent to be honest. I don't doubt that some may have had bad experiences, but both my purchases have been smooth. Why the 4 stars? Well, the day my first dryer arrived, I received an email on a promotion for an S4 dryer and 3Kgs of filament for some £28 cheaper than I had just paid. Just found that poor.
Great filament for the price! I’ve been ordering in bulk and may have an issue or 2 with the roll being tight but otherwise no complaints here compared to other brands. One thing I will say is I wish they had more color variations in the future but I still love the colors now.
im buying from sunlu since 2 years
I've started a small print farm and purchased over 200 spools of Sunlu filament so far and been very happy with the quality and price. I plan on standardizing on Sunlu going forward.
Seeing lots of bad reviews lately; I've had 5* service but have old stock, so not sure if something has changed. I'm here because I was asked to leave a 5* review for $20. While I still think they are 5*, bambu is obviously easier and cheaper for me as I buy huge bulk 20-40+ rolls at a time, but do like their additional color rainbows. I'm hoping the order I'm about to place is still 5* worthy
really fast delivery, and great variety of filament at very good prices! And a big congratulations to eu for adapting their spools to the AMS bambu lab.
Nice Filament，I love it~
Prompt delivery, good product
I only 3d print as a hobbyist so I am very happy with this filament I started with sunlu and found it to be realy good worked well with my ender and now own two bambu and still works well. Shipping isn’t to bad as I allways order in advance from sunlu direct so time isn’t critical but have orderd on a next day from Amazon. Some good deals on the website at moment so keep these deals coming perhaps even for the silks and rainbow colours. Thanks for the quality and vast variety of colours and a good price.
Great products and fast delivery. Highly recommended! We only buy SunLu!
We have been using Sunlu PETG filament for well over a year (Going through hundreds of rolls) and had an excellent experience with it. Low stringing and neatly wound, as promised. I recommend their PETG products and will be using some of their PLA+ 2.0 soon.
Their resin and filaments work pretty well and often times you can get them at a really good price. Are there better options for stronger resin out there? Yes, of course there are, but you will end up paying more depending on how strong you want your resin to be. I think Sunlu is reasonably priced and their resin holds up pretty well for miniatures. If you are going to be rough with them, then yeah, they are gonna break, but if you treat them like models instead of toys, then you will be fine. I would recommend this company to anyone who does 3D printing.
Simply the best around, SunLu are my go to shop for all filament. First dispatch every time. I will not shop anywhere else.
Very good product and great and very quick service definitely recommend
Fast delivery, great product to use with really good results thanks sunlu.
