Best 3D Printer Filament Deals: PLA, ABS, PETG and more
Keep your materials stocked up and ready to print with the best deals on PLA, ABS and more.
3D printing is a fantastic pastime. I’ve been doing it for nearly a decade now, and while there have been a lot of changes to the best 3D printers in terms of speed and quality, the basic materials you print with are the same. Most people are familiar with FDM printers — the type that use long strands of plastic to build layers on a print surface — and the material used to make models with them, called filament.
Filament comes in all different colors and chemical compositions — which our best 3D printing filament list explains in more detail — and ranges in price from less than $20 to hundreds of dollars, depending on what you need. Buying filament in bulk is often necessary, so it’s worth seeking out good deals. To save you some time, we’ve done the legwork for you and found as many filament deals as we can.

Transitional filament, which mixes multiple colors, has been around for a while, but it normally changes a model’s color from the bottom to the top. Quantum is actually two colors fused across the width of the model, allowing it to change color from left to right. This results in a mesmerizing transition. I love using it for all sorts of different projects. From vases to giant articulated octopuses, it makes any model look breathtaking.

Elegoo
If you want to create a huge project or print the same thing over and over, you need a lot of filament. Elegoo’s bulk discount makes each roll cost just $10, a fantastic bargain. It’s only black PLA, but it’s good enough if you’re postprocessing it anyway.
Ten rolls of filament for $100 is amazing and if you can afford the initial outlay you’ll save yourself a bunch of money.
Stronhero 3D
Unique transition filaments are one of my favorite things. This PETG goes from a deep blue to an almost watery clear blue and back again, giving it a look of ocean waves. It’s beautiful. It is PETG, so you’ll need to ensure your printer is dialed in, but it’s worth the extra print time.
Ataraxia Art
Flexible PLA is on the border of PLA and TPU, but it does print well on direct drive printers such as the Prusa Mk3s or the new Ankermake M5.
I used it to make an amazing 3D-printed Mandalorian helmet for my 4-year-old daughter, so she can enjoy it without fear of damaging it. Any time you can get this on a discount it is worth doing.
iSANMATE
This four-pack includes smaller rolls of filament, and it’s more of a tester set than a full roll. The glow-in-the-dark colors make it a great buy, but remember that although it will print using the PLA settings, it’s abrasive to soft brass nozzles. If you’re hoping to print a lot of this, you’ll need to buy a hardened nozzle or be ready to replace your brass nozzles constantly.
Sunlu
Sunlu has been making filament for a while now, and it offers excellent quality at a low price. If you’re working with ABS and you need to lay in a store of spools, Sunlu is a great option. You can buy this budget filament without worrying about its quality.
SainSmart
TPU is a lot of fun to 3D print with. It prints as a rubbery material, much like a phone case. This particular filament from SainSmart is even more interesting because it’s heat-sensitive. When it’s cool, the material is a deep orange color, but it changes into a bright yellow as it gets warmer.
TPU is great for applications that need to be tough, but require a lot of give in the material.

This $20K Humanoid Robot Promises to Tidy Your Home. But There Are Strings Attached
The new Neo robot from 1X is designed to do chores. It’ll need help from you — and from folks behind the curtain.
It stands 5 feet, 6 inches tall, weighs about as much as a golden retriever and costs near the price of a brand-new budget car.
This is Neo, the humanoid robot. It’s billed as a personal assistant you can talk to and eventually rely on to take care of everyday tasks, such as loading the dishwasher and folding laundry.
Neo doesn’t work cheap. It’ll cost you $20,000. And even then, you’ll still have to train this new home bot, and possibly need a remote assist as well.
If that sounds enticing, preorders are now open (for a mere $200 down). You’ll be signing up as an early adopter for what Neo’s maker, a California-based company called 1X, is calling a «consumer-ready humanoid.» That’s opposed to other humanoids under development from the likes of Tesla and Figure, which are, for the moment at least, more focused on factory environments.
Neo is a whole order of magnitude different from robot vacuums like those from Roomba, Eufy and Ecovacs, and embodies a long-running sci-fi fantasy of robot maids and butlers doing chores and picking up after us. If this is the future, read on for more of what’s in store.
Don’t miss any of our unbiased tech content and lab-based reviews. Add CNET as a preferred Google source.
What the Neo robot can do around the house
The pitch from 1X is that Neo can do all manner of household chores: fold laundry, run a vacuum, tidy shelves, bring in the groceries. It can open doors, climb stairs and even act as a home entertainment system.
Neo appears to move smoothly, with a soft, almost human-like gait, thanks to 1X’s tendon-driven motor system that gives it gentle motion and impressive strength. The company says it can lift up to 154 pounds and carry 55 pounds, but it is quieter than a refrigerator. It’s covered in soft materials and neutral colors, making it look less intimidating than metallic prototypes from other companies.
The company says Neo has a 4-hour runtime. Its hands are IP68-rated, meaning they’re submersible in water. It can connect via Wi-Fi, Bluetooth and 5G. For conversation, it has a built-in LLM, the same sort of AI technology that powers ChatGPT and Gemini.
The primary way to control the Neo robot will be by speaking to it, just as if it were a person in your home.
Still, Neo’s usefulness today depends heavily on how you define useful. The Wall Street Journal’s Joanna Stern got an up-close look at Neo at 1X’s headquarters and found that, at least for now, it’s largely teleoperated, meaning a human often operates it remotely using a virtual-reality headset and controllers.
«I didn’t see Neo do anything autonomously, although the company did share a video of Neo opening a door on its own,» Stern wrote last week.
1X CEO Bernt Børnich told her that Neo will do most things autonomously in 2026, though he also acknowledged that the quality «may lag at first.»
The company’s FAQ says that for any chore request Neo doesn’t know how to accomplish, «you can schedule a 1X Expert to guide it» to help the robot «learn while getting the job done.»
What you need to know about Neo and privacy
Part of what early adopters are signing up for is to let Neo learn from their environment so that future versions can operate more independently.
That learning process raises privacy and trust questions. The robot uses a mix of visual, audio and contextual intelligence — meaning it can see, hear and remember interactions with users throughout their homes.
«If you buy this product, it is because you’re OK with that social contract,» Børnich told the Journal. «It’s less about Neo instantly doing your chores and more about you helping Neo learn to do them safely and effectively.»
Neo’s reliance on human operation behind the scenes prompted a response from John Carmack, a computer industry luminary known for his work with VR systems and the lead programmer of classic video games including Doom and Quake.
«Companies selling the dream of autonomous household humanoid robots today would be better off embracing reality and selling ‘remote operated household help’,» he wrote in a post on the X social network (formerly Twitter) on Monday.
1X says it’s taking steps to protect your privacy: Neo listens only when it recognizes it’s being addressed, and its cameras will blur out humans. You can restrict Neo from entering or viewing specific areas of your home, and the robot will never be teleoperated without owner approval, the company says.
But inviting an AI-equipped humanoid to observe your home life isn’t a small step.
The first units will ship to customers in the US in 2026. There is a $499 monthly subscription alternative to the $20,000 full-purchase price, though that will be available at an unspecified later date. A broader international rollout is promised for 2027.
Neo’s got a long road ahead of it to live up to the expectations set by Rosie the Robot in The Jetsons way back when. But this is no Hanna-Barbera cartoon. What we’re seeing now is a much more tangible harbinger of change.

I Wish Nintendo’s New Switch 2 Zelda Game Was an Actual Zelda Game
Hyrule Warriors: Age of Imprisonment has great graphics, a great story and Zelda is actually in it. But the gameplay makes me wish for another true Zelda title instead.
I’ve never been a Hyrule Warriors fan. Keep that in mind when I say that Nintendo’s new Switch 2-exclusive Zelda-universe game has impressed me in several ways, but the gameplay isn’t one of them. Still, this Zelda spinoff has succeeded in showing off the Switch 2’s graphics power. Now can we have a true Switch 2 exclusive Zelda game next?
The upgraded graphics in Tears of the Kingdom and Breath of the Wild has made the Switch 2 a great way to play recent Zelda games, which had stretched the Switch’s capabilities to the limit before. And they’re both well worth revisiting, because they’re engrossing, enchanting, weird, epic wonders. Hyrule Warriors: Age of Imprisonment, another in the Koei-Tecmo developed spinoff series of Zelda-themed games, is a prequel to Tears of the Kingdom. It’s the story of Zelda traveling back in time to ancient Hyrule, and the origins of Ganondorf’s evil. I’m here for that, but a lot of hack and slash battles are in my way.
A handful of hours in, I can say that the production values are wonderful. The voices and characters and worlds feel authentically Zelda. I feel like I’m getting a new chapter in the story I’d already been following. The Switch 2’s graphics show off smooth animation, too, even when battles can span hundreds of enemies.
But the game’s central style, which is endless slashing fights through hordes of enemies, gets boring for me. That’s what Hyrule Warriors is about, but the game so far feels more repetitive than strategic. And I just keep button-mashing to get to the next story chapter. For anyone who’s played Hyrule Warriors: Age of Calamity, expect more of the same, for the most part.
I do like that the big map includes parts in the depths and in the sky, mirroring the tri-level appeal of Tears of the Kingdom. But Age of Calamity isn’t a free-wandering game. Missions open up around the map, each one opening a contained map to battle through. Along the way, you unlock an impressive roster of Hyrule characters you can control.
As a Switch 2 exclusive to tempt Nintendo fans to make the console upgrade, it feels like a half success. I admire the production values, and I want to keep playing just to see where the story goes. But as a purchase, it’s a distant third to Donkey Kong Bananza and Mario Kart World.
Hyrule Warriors fans, you probably know what you’re probably in for, and will likely get this game regardless. Serious Zelda fans, you may enjoy it just for the story elements alone.
As for me? I think I’ll play some more, but I’m already sort of tuning the game out a bit. I want more exploration, more puzzles, more curiosity. This game’s not about that. But it does show me how good a true next-gen Zelda could be on the Switch 2, whenever Nintendo decides to make that happen.
