GST is my go-to for single colour PLA+ There is quite some colour variation between batches so make sure you order enough. The fluorescent colours are awesome!

Good filament, good price, what’s bad instead it’s that 80% of the spools came with no more vacuum sealing, there’s some problems in the weak nylon bags, weak packing/shipping part of the whole thing

Great price

Great prices, various colors, but the spools advertised as 1kg are more like 850-900g...
A great filament for prototypes

Do not buy from gst3d.eu

Do not buy from gst3d.eu. I bought 10 rolls and got pure crap. Open a case with them and mailed back and forth. The last mail they asked me to make a video of the problem and take pictures and I did. Using a babmbu labs p1s so I took time laps from the printer and photos. Then they stopped responding.. do NOT buy from this place couse when / if you get problems they will stop responding and just don’t care about your problem la. Buy sunlu or something instead. Just go to AliExpress and search for sunlu. If there’s a problem with something AliExpress will help to be the man in the middle.

Hi Peter,

Thanks for sharing your experience. We're sorry to hear the rolls you received didn’t meet your expectations. We saw that you provided both photos and a time-lapse video using your Bambu Labs P1S, which we truly appreciate. We'd love to take a closer look at your case and understand what went wrong in the follow-up process.

At GST3D, we not only offer filament but also technical support to help with your printing projects. Whether you're a professional or a hobbyist, our goal is to support you throughout the process.

We’d be happy to have you back and show you we can do better. If you could share your order number, we’ll gladly review your case and work toward a proper solution.

Best regards, The GST3D Team

Got 12kg of high quality filament for cheap!

Ordered 12 kg of filament, mostly PETG-CF, TPU and some PLA. They all seem fine and specialty filament for a very good price.
I have ordered from all over the world in the last decade, this seems as good as any of my other suppliers.

Bad Quality

Bought a roll of silver TPU from GST3D.
It was useless.
Diameter of filament is not consistent, and fluctuates from 1.75 to 2mm+, causing the extruder to clog and potentially causing damage to it, as after about 4-5 failures, it started rattling like crazy.
Contacted the shop, they exchanged the roll for one from a new batch.
Second roll ALSO has the same issue, encountered at least 2 times in the first 3 meters of filament.
I do not recomment for purchase, their materials can potentially not only waste your time, but also cause material damages from their malfunctioning.

Don't buy this filament

Don't buy this filament. It is the by far the worst filament I've ever had. Ordered a package of 6 rolls. 4 out of 6 are pure garbage. It seems like there is some kind of coating on it. And after some time printing this is causing extrusion issues. When I take it back out the printer it looks like it had some transparent sleeve. I've never seen this before with any other brand

When they saw my Google review they asked me n to contact them. I contacted them by email, more then one week later still no reaction. No reaction in chat or whatsapp. So it seems they want to pretend they care, but they don't.

Very bad quality, seller does not respond to emails

I ordered 8 rolls of white pla. Unfortunately they are getting struck in the printers. I use 3 prusa I3 Mk3S+ printers. I tried 3 rolls and on all the 3 printers. Same results. stuck while printing.

For your information. These printers are running 20 hours a day for 2 years. They never have problems with other pla rolls. As you understand I am very disappointed because I cannot use your pla.

I emailed them several times but they don't respond to my messages. DON'T USE THIS BAD QUALITY PRODUCT!!!

Really garbage!

The filament is not always wound properly. Rolls are often completely skewed as if they have been deformed by heat. The filament is sometimes not smooth. The diameter of the filament is not always correct. My last roll was 2.50 mm at the end instead of 1.75. They don't respond to emails. Why still 2 stars? The majority of the rolls are fair to good.

New update: I have thrown away my 5th almost complete role. Diameter varied from 1.75 to 2.01mm. Previous roll stuck completely together. Please do not buy from this firm. Buying in bulk from them was a big mistake.

Great Filament with Room for Improvement in Customer Support

I recently purchased filament from this website, and overall, I am quite satisfied with the product. It offers an excellent value for money, making it the best choice among the affordable PLA options. The colors are vibrant, and I have never encountered any issues while printing, even after using over 100kg of filament.

The shipping was relatively fast, and I consistently received my orders within a week. Prompt delivery is always appreciated, and this company has been consistent in that regard.

However, the main area that needs improvement is their customer support service. Whether it's through email or web chat, it is often challenging to receive a response, even for relatively simple inquiries. I had a particular issue with not receiving the shipping number, and it was quite frustrating not being able to get a timely response. Enhancing the responsiveness and efficiency of their customer support team would greatly benefit the overall experience for customers.

Despite the customer support concerns, I intend to continue purchasing from this website due to the high quality of their products. However, I do hope they will prioritize improving their support system and website usability in the future. It would significantly enhance the overall customer satisfaction and make the purchasing experience even more enjoyable.

Bad service

I bought a pack of 6kg, one of them was the wrong color. I asked for an exchange and they said "the best we can do is 10% off your next order" I said no I want it replaced and since then no response, and no coupon
