Frequent Asked Questions

What are your Recommended Print Settings?

For the bed we recommend 85C on the first layer and 90C after that. For the nozzle we recommend between 225-245C. We have had success with higher and lower temperatures, outside of that range, but it depends on your printer and your climate. (Pictured below is a temperature tower from 190C to 230C)

As for printing speed, we recommend you start slow, perhaps 30mm/s and when you've got the printer tuned in, you can easily get 75 and better with a 0.2 layer and close to 100 with 0.3. Our stuff prints silky smooth!

Why no PLA?

That’s a question we get all the time. I mean, it’s by far the number one best-selling 3D filament. We gotta be crazy not to offer it, right? Dozens of people in our industry have told us we’ll never succeed without that line. Well, I guess that remains to be seen, but we’re not going there. Probably ever. So, why not? Quite frankly for a very good reason: in our 25-year recycling history, we’ve only come across it twice, so we have no experience remelting it into a usable pellet. And we’re ALL ABOUT recycling. Now, that said, we ARE looking into recycling failed PLA prints. Its not as easy as it seems, and we'll be limited in color, but for sure, we're having high level discussions with a few associates. Its why we never say never.

What about dehydrating your filament? Should we store it in a dry box?

Yes, typically PET-G loves humidity, but of course, makers don’t. However, under normal relative humidity, our PET-G handles atmospheric moisture quite well. Sure, if you live in the South of the US, you probably should store our filament in a dry box, but if not, you’ll likely be fine just leaving it in an air-conditioned room.
Now, that said, do N O T dry our filament in an oven. Please. Ovens WILL do the trick, but they're also likely to melt the spool and possibly even the filament. Why would that happen? Well, the air in an oven is static and as much as you think it is, its probably not calibrated all that well, either. So, if you put our spool in your kitchen oven and that spot is super heated, there's a good chance it'll melt.
If you're running any reasonable amount of PET-G (and/or nylon), you should probably invest in a dehydrator. They're available in big box stores or online for about $40.

I see you sell only recycled plastics. Why?

We thought about a virgin line, but why turn our backs on our own identity? Its THAT experience and THOSE relationships which brought us to where we are now. Our PET-G can print from 205°C to 250°C with no loss of layer adhesion and miniscule stringing. So, you get a great product and are using 100% recycled plastics, made right here, in America.
We’re proud to be GreenGate3D: Your entryway to recycled filament.

Is GreenGate3D’s PET-G food compliant?

Many printers know that PET-G IS a food-safe plastic, and while our raw material PET-G pellets are pristine-clean, GreenGate3D doesn’t extrude in an FDA-approved lab. So, while the actual polymer is often used in food packaging, we’d rather not make claims that you can use our goods for anything you eat, drink or smoke… AND, inject is probably not a good idea either…

What does the future hold for GreenGate3D?

Engineering-grade materials, like CF/PET-G, Flexible TPU, and Nylon 6,6. We’ll also offer custom color matches, large and master spools, a newsletter, color naming contests and plenty more tricks up our green sleeves…

How close are your photos to real life?

In our earliest days, EVERY PICTURE YOU SAW from our product catalog is an actual photograph, taken by Tiffany Cohen. Tiffany is a multi-talented mom and businesswoman, working in finance, who has her own blog ( and does work for companies as Bed, Bath, and Beyond, Cento Fine Foods, Mott’s, as well as a number of restaurants. Since then, we brought on Esteban Devia, a super-talented 3D animator, who's done the overwhelming majority of pictures and videos, seen on our website, as well as Twitter, Instagram, YouTube, and on our other social media pages.
As talented as they both are, we need to note that the colors in the photos may be different that what you see with a printed model, since every computer processes colors and each screen generates video slightly differently. In any case, they're darn close to what you'll get when you print from our filament.

Is GreenGate3D RoHS Compliant?

Absolutely! Here are our RoHS Compliance files:
