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.

YouTubers Sue Amazon, Claim AI Tool Was Trained on Scraped Videos
The lawsuit alleges that Amazon bypassed YouTube protections to collect content for its generative AI video system.
A group of YouTube creators is suing Amazon, accusing the tech giant of secretly scraping their videos to train its AI video model without permission.
The proposed class action lawsuit, filed in federal court in Seattle, alleges Amazon used automated tools to download and extract data from millions of YouTube videos to build and improve its Nova Reel generative AI system — a model that can create short videos from text prompts and images.
At the center of the complaint is how that data was obtained. The plaintiffs claim that Amazon bypassed YouTube’s protections using virtual machines and rotating IP addresses to avoid detection, effectively sidestepping the platform’s safeguards against bulk downloading.
The lawsuit was brought by several creators, including Ted Entertainment (the company behind the H3 Podcast and h3h3 Productions), as well as individual YouTubers and channel operators. They argue that the alleged scraping violated copyright law and the Digital Millennium Copyright Act, and are seeking damages as well as an injunction to stop the practice.
Amazon did not respond to a request for comment.
The case lands at a pivotal moment for generative AI, as courts weigh whether training on copyrighted material qualifies as fair use and how much control creators retain once their work is used to build these systems. The disputes have often centered on written material, which has been at the center of the AI revolution for several years, while AI video generators such as OpenAI’s Sora and Google’s Veo have emerged more recently.
The lawsuit is one of dozens testing the boundaries of AI training practices, alongside high-profile cases from authors, artists and news organizations, including lawsuits against OpenAI and Meta, all circling the same unresolved question: Where does fair use end and infringement begin?

The Galaxy Z TriFold Is Back. You Can Buy It From Samsung Soon
The $2,899 phone paused its sales in March after selling through its inventory, but Samsung is bringing it back to its online store.
Samsung’s $2,899 Galaxy Z TriFold is going back on sale on Friday, following a halt to its sales in March after the foldable phone sold through its inventory. Samsung has announced the TriFold’s return with a countdown clock on the phone’s online store page along with a Wednesday newsletter email sent to customers.
The initial pause, which Samsung said at the time was related to the TriFold being a «super-premium device in limited quantities,» happened after just three months of availability. The TriFold first went on sale in South Korea on Dec. 12 and then arrived in Samsung’s US store on Jan. 30. The TriFold sold out in the US within minutes of going on sale — which I know personally after joining my colleagues that morning in an attempt to buy it. Thankfully Senior Reporter Abrar Al-Heeti succeeded, and then reviewed the TriFold.
It’s unclear whether the Galaxy Z TriFold is now permanently returning to Samsung’s online store or if it is again on sale until its stock sells through. Given that the phone is very expensive, and unfolds to reveal a large, 10-inch display, it wouldn’t be surprising if its stock will be in limited quantities. We’ve asked a Samsung representative to clarify and will update if we hear more.
The Galaxy Z TriFold’s return also comes ahead of the summer season when we expect a slew of other foldable phones: Samsung typically refreshes its Galaxy Z Fold and Z Flip line in July or August, and Motorola has announced its first book-style Razr Fold phone will also debut during the season. And Apple’s rumored iPhone Fold (or perhaps iPhone Ultra based on latest rumors) could also be teased later this year.
