Start Your Project Off Right With the Best 3D Printing Filament in 2022
There are a lot of different 3D-printing materials out there. Here’s how to pick the right one for your project.

You’ve got the best 3D printer you can buy, but without materials, you can’t get printing. If you chose a fused deposition modeling, or FDM, printer — the most common type of 3D printer for hobbyists — you’ll need a few rolls of special plastic. The material we use for FDM 3D printing is called filament and it’s an easy material to pick up. There are, however, different types of filament, each good for certain projects and terrible for others. You’ll want to make sure you’re using the best filament for the job at hand, or it may fail.
I’ve put together this primer of the different types of filament as well as choices of the best filaments from my favorite brands. This will be updated regularly and contains some great choices for you to start.


It’s important to choose both the right type of material and the right brand of that type, be it PLA, ABS or something more exotic. Here are the best of each of the five main filament types.

Those categories are:


PLA is the easiest material to use to make awesome things.
James Bricknell/CNETPolylactic acid
Polylactic acid, or PLA, is the most common 3D printing filament and the easiest to use. Unlike most plastics, it’s made from corn starches so it is non-toxic and, in theory, compostable, though it takes an industrial composter to do it. PLA uses a fairly low heat — between 190 and 215 degrees Celsius (or between 374 and 419 degrees Fahrenheit) — to melt the plastic for extrusion so it is the safest of the filaments. Almost every FDM 3D printer in the world can print PLA.
PLA pros
- Nontoxic
- No awful smell
- Easy to use for a beginner
- Almost universally usable on any FDM printer
- Very cheap
PLA cons
- Can require a lot of sanding
- Can easily warp in the sun or high-temp environments
- Can be brittle
MatterHackers
Build PLA from MatterHackers is great for projects that require finishing (sanding, painting and so on). I have about 12 rolls of it in my workshop, and use it for large projects, including my Mandalorian armor or cosplay swords. The dimensional accuracy — how consistent the diameter is along the length of the roll — is good, though nothing mind-blowing. It’s well within the sweet zone.
Post-processing is where Build Series PLA shines. It is simple to sand and holds paint well, as long as you use a good primer and filler first. Like all PLA, it holds together well using superglue and even takes putty and Bondo without complaint.
Flashforge
The color of this PLA is hard to describe, but it is beautiful. It has a purple-blue-green hue to it and looks like metal that’s been heated up a lot. Right now it’s probably my favorite-looking filament on my shelf.
It’s also easy to print with, and because of the shifting colors it hides layer lines well. If you’re looking for a dark filament that you aren’t painting over, I’d pick up a few rolls of this today.
MatterHackers
For something completely different in the PLA world, check out Quantum by MatterHackers. Transitional filament, mixing multiple colors, has been around for a while, but it normally changes color across the length of the material. This causes it to change color as it goes further up the model.
Quantum is actually two colors fused across the entire width, so you get an amazing transition from left to right. It’s absolutely mesmerizing, and I love using it for all sorts of different projects. From vases to giant articulated octopuses, it makes any model look breathtaking.
Cookiecad
I have been meaning to buy some of this beautiful filament for some time now, and I’m really happy I did. The color is almost exactly the same as Mint choc chip ice cream and the tiny flecks of marble color enhance the look even more. It prints great, with a nice glossy finish, and I found printing it at a higher temperature brings out that gloss really well.
More importantly than the print quality though, I love it for the way it makes me feel. The color just makes me happy and reminds me of days at the beach with my kids. It’s gorgeous.
Sunlu
Sunlu is one of those filaments that is really easy to get hold of and prints well every time you use it. It says its dimensional accuracy is +/- 0.02mm, but I’ve been lucky to never have the variance above 0.01mm in hands-on use.
Sunlu also comes in some beautiful matte colors, which is a welcome break from more common shiny filaments. Sanding and printing with it is easy. If you’re new to 3D printing and need to increase your collection of PLA, this is a cheap way to do it.
James Bricknell/CNET
Rainbow filament tends to transition between colors very slowly. This means you often get only one or two colors per model. Creality’s latest rainbow filament has a much shorter transition, so you get a much nicer rainbow effect across your models. It looks great on this amazing dragon from Fotis Mint.
Polymaker
For projects you can show off without having to paint them first, PolyTerra might be for you. The colors are vivid, and because they are matte, you don’t lose details in the reflections like with shiny filament.
PolyTerra also comes in recycled cardboard reels, and the creator, Polymaker, will plant a tree in the area where the roll was bought to help offset the cardboard used. This filament is still plastic of course, but it helps my conscience to use it.
Ataraxia Art
In this article about this flexible PLA I explained how, although this isn’t technically PLA, it does print much easier than TPU, a more common flexible filament. I used it to print an amazing Mandalorian Blacksmith helmet for my 4-year-old. She can’t break it because it’s so bouncy.
This isn’t for newbies, though. It took a lot of trial and error to get the setting for my 3D printer right, and because it is so soft the accuracy can be pretty wonky. But for something that’s different from normal PLA, it is worth checking out.
Acrylonitrile butadiene styrene
ABS was one of the more 3D printing filaments a few years back, and it still has some excellent uses. The biggest downside is the toxicity. You don’t want to breathe in ABS as it melts, so you’ll need a well-ventilated area. That aside, it’s sturdier and more heat-resistant than PLA. Most printers can print ABS, but you’ll need a heated bed that can reach 100 degrees Celsius for best results and protecting your printing job in an enclosed printer is a good idea.
ABS pros
- Can withstand a lot of heat
- Easy to sand
- Can be smoothed with acetone for a perfect shine
ABS cons
- Its fumes are toxic so it requires ventilation
- It needs far more heat to print than PLA
- You will need an enclosure to get good results
Inland
Inland makes good filament across the board and its ABS is no different. I’ve never had issues with the dimensions, and the final product has consistent layer lines. Sanding Inland ABS is a joy as the material can be wet-sanded to a smooth finish.
MatterHackers
Fillamentum is one of my favorite ABS makers. The colors are always so vibrant, and while it costs a little more than the competition, it keeps that vibrancy even after the model is finished printing. If you’re looking for ABS that you don’t need to paint, Fillamentum is a great place to start.
Polyethylene terephthalate glycol
PETG is chemically similar to the plastic that water and soft drink bottles are made of, and is a great alternative to ABS. It has the heat-resistant properties of ABS without the toxic fumes and can be sanded much like PLA. Most FDM printers that can print PLA can print PETG, though it takes a little more effort to get right.
PETG pros
- Easier to print than ABS
- Holds a finish well
- Easier to store than other filaments
PETG cons
- Requires high temps, which can damage printer parts over time.
Protomaker
This USA-made PETG has an excellent glassy look that is hard to achieve in melted plastic. The aqua color is subtle and gives the appearance of a stained glass window when printed at the high end of its temperature scale.
Printing with it was easy, though the roll is a little big for printers like the Bambu Lab X1, that has enclosed filament system.
Matterhackers
The Pro series filament from MatterHackers is a much nicer product than a lot of standard PETG. Yes, it costs a little more, but it’s designed to help reduce some of the issues that filament suffers from. It reduces shrinkage, so the part you make is as close to the part you designed as possible. This is a great material for those who make 3D printed models for a living, rather than a hobby.
Overture
Overture PETG is a favorite because it comes in an economical two-pack, making it ideal for multiple or larger jobs. I’ve used a lot of Overture products, including PETG and PLA, and they always print well. I once printed an 11-foot-long Masamune sword using Overture and it came out looking awesome.
Thermoplastic polyurethane
TPU is a flexible material that can make cool rubbery models. Most people use it to 3D print phone cases, but more serious modelers often use it to create connectors or flexible hinges to other materials. It can be a difficult material to work with and is best used on a direct-drive 3D printer such as the Prusa Mk3s, rather than a Bowden printer like the Anycubic Vyper. A direct drive printer places the gears to move the filament directly on the print head, while a Bowden setup has them on the frame of the printer.
TPU pros
- Flexible
- Won’t warp in the heat
- Available in fun colors
TPU cons
- Terrible for making solid prints
- Hard to work with on budget printers
MatterHackers
MatterHackers Build Series Materials sit in the perfect balance between usability and cost. Yes, I’ve had failures with the Build Series, but once you get it dialed into your printer, you can make dozens of fun, springy models.
I like to use it to make fun toys for my kid’s preschool as they can be thrown around with no fear of breaking into small, sharp pieces.
Exotic filaments
Exotic filaments are ones that are outside the normal five choices, or interesting variations on those choices. They’re often PLA mixed with carbon fiber or glow-in-the-dark chemicals and something that prints outside the normal parameters of a 3D printer. You’ll often need to upgrade your printer nozzle to use these. It’s advanced stuff, but I wanted to show you my favorite glow-in-the-dark filament, which is fun to print with.
Amolen PLA
Glow-in-the-dark filament normally comes in a standard «radioactive» green, but this beautiful roll transitions through multiple colors. It’s simply gorgeous.
It’s also worthwhile to buy some replacement brass nozzles for your printer as glow-in-the-dark filament can chew them up pretty quickly because the glowing material is more abrasive than standard colors.
Filament FAQ
What filament should I start with?
If you’re buying a printer for the first time, the best choice of filament is PLA. It is the easiest to print with, the safest in terms of fumes and the most readily available. Think about laying in a store of PLA when you first start. A 1-kilogram roll feels like a lot, but once you get the itch, materials get eaten up quickly.
Are there different sizes of filament?
Yes. There are two main thicknesses of filament and if you get them mixed up, your machine won’t print.
1.75mm filament is the most common. It’s been adopted by most of the 3D manufacturers in the world and if you have an entry-level printer, it’s likely to run on 1.75mm filament.
Some 3D printers still use the thicker 3mm style, though, so make sure you know which one yours uses before you spend a lot of money on the wrong material.
Are all filaments toxic?
When 3D printing with any filament, it is important to remember that you are essentially burning plastic. Inhaling that kind of thing is never going to be good, but not all filaments are equally bad.
Of the four main filament types, ABS is easily the most toxic. You shouldn’t think about printing it unless you have a well-ventilated space away from your day-to-day living spaces. I have a workshop with a full ventilation system and the fumes can still be pretty bad.
Both PLA and PETG are considered nontoxic, though you still want to keep your area ventilated as you use them. Both filaments are safe to print inside your home and while the fumes can smell pretty bad, they’re not classed as carcinogenic. While other forms of TPU can be toxic, the filament you use for 3D printing is considered nontoxic and nonreactive so you should be fine printing that as well.
Does the filament keep the same color after printing?
Normally yes. If your printer isn’t calibrated well, it could burn the filament, which would discolor it. But normally the color accuracy is pretty close.
A special note on clear plastics: You will not be able to get a completely translucent print with filament. The nature of the printing process makes any clear plastic misty and infill makes it blurry as well. If you are looking to print glass-like models, you will need a resin printer.


Having the right diameter makes for a better print.
Dan Ackerman/CNETHow we test filament
The testing of filament is mainly focused on a few details: Dimensional accuracy, winding precision, and printing quality. Winding precision is a visual test where I check to make sure the filament works well on the spool, without any crossovers that can cause snags while printing.
Print quality is done using a CNET calibration test that I use to test all of the 3D printers I review. When checking for filament quality, I’m looking for noticeable roughness and missing filament where moisture or other contaminants have interrupted the process of melting and cooling.


Dimensional accuracy is perhaps the most important test as it measures the consistency of filament. As you move along, the filament changes in diameter will cause the 3D printer to over- or under-extrude filament. This creates noticeable scarring in your model, or worse, complete failure. You want the material to have the same diameter the whole way through.
To measure the accuracy, I take a 5-meter piece of filament from the beginning, middle and end of the roll and measure the diameter at four equally spaced points. I then add all of those measurements up and divide the total by 12 — the total number of measurements taken — to give me an average across the roll. Most modern printers use 1.75mm filament so you want the filament to be as close to that as possible.
Great filament has a variance of +/- 0.02mm, good filament is +/- 0.03mm and rough filament is anything +/- 0.05mm. All of the filaments we have recommended here are at least 0.03mm on average.

Uber Adds Rental Car Delivery and Discounted Airport Rides Before July 4 Weekend Surge
Look for new airport pickup options and more flexibility for hotel food deliveries.

With AAA forecasting that a record-breaking 72 million Americans will travel during the week of July 4, ride-hailing and delivery company Uber is launching various updates to make summer vacations more seamless. Uber is significantly expanding its rental-car delivery service, introducing new airport options for ride-sharing and prescheduled pickups, and adding more flexibility for hotel food deliveries.

Car rental dropoff expands
One of the biggest updates is the expansion of Uber Rent — the service’s car-rental department — by adding car delivery, which allows users to have a rental car dropped off at their home, office or hotel. This summer, the service is rolling out to 15 additional US cities, including Dallas, Phoenix, Charlotte and Las Vegas, bringing the total to 24 cities nationwide.
Travelers can book a rental car as little as 2 hours in advance or up to six months ahead. Uber also notes that there’s no fee to cancel, as long as it’s at least 2 hours before the scheduled drop-off.
More affordable airport rides
Uber is also expanding Uber Share at Airports, a carpool-style option where travelers heading to or from the airport can share a ride with one other passenger and save up to 25% compared to a standard UberX, which is the regular Uber tier. Even if no match is found, riders still pay the discounted rate.
This feature is now available at more than 40 additional airports, including Chicago Midway, Nashville, Washington Reagan, and international cities like Paris, Lisbon and Stockholm.
Enhanced hotel food delivery
The company is adding new delivery options for travelers relying on Uber Eats while staying at hotels. Users can now select how they want their food dropped off: meeting the courier in the lobby, having the food left at the front desk or requesting direct delivery to their hotel room doorway.
Travelers staying at Marriott properties can also now earn Marriott Bonvoy points on Uber Eats orders, provided their loyalty account is linked in the app.
More airport pickup options in the suburbs
Uber is also expanding its Reserve Airport Pickup feature to 70 more airports in the US and Canada, with a focus on smaller towns and suburban destinations such as Reno, Green Bay and Sarasota. Reserve rides can be scheduled in advance, a convenience for travelers flying into areas with fewer transit options.
These updates are arriving just in time for one of the busiest travel weeks of the year. Additional changes are listed in the Uber Newsroom post.

Microsoft Layoffs Are Here and These 3 Games Have Already Been Canceled
Microsoft is cutting more than 9,000 jobs — 4% of its global workforce — and as a result, Everwild and the Perfect Dark reboot have been put out to pasture.

Microsoft is moving ahead with mass layoffs, cutting a little less than 4% of its workforce or about 9,000 roles across the company. As a result, multiple games brewing within Xbox Game Studios were canceled, including some fairly high-profile projects.
When reached for comment, Microsoft directed CNET to reports Wednesday by Variety, confirming their accuracy.
«To position Gaming for enduring success and allow us to focus on strategic growth areas, we will end or decrease work in certain areas of the business and follow Microsoft’s lead in removing layers of management to increase agility and effectiveness,» Microsoft Gaming chief Phil Spencer wrote in a staff memo Wednesday morning, as published by Variety.
Xbox Game Studios head Matt Booty confirmed the game cancellations in an internal email published by Variety, naming Perfect Dark and Everwild specifically, as well as other «unannounced» titles.
«We have made the decision to stop development of Perfect Dark and Everwild as well as wind down several unannounced projects across our portfolio,» Booty wrote in the email. «As part of this, we are closing one of our studios, The Initiative.»
Booty added that the decisions to axe these games «reflect a broader effort to adjust priorities and focus resources to set up our teams for greater success within a changing industry landscape. We did not make these choices lightly, as each project and team represent years of effort, imagination and commitment.»
What Xbox games have been canceled?
Perhaps the most significant title canceled amid these new layoffs was a reboot of the classic FPS series, Perfect Dark. The studio that had been working on this new title, The Initiative, will be shut down entirely.
The long-awaited new entry in the sci-fi espionage series has been in the works since the studio opened in 2018 and first showed off gameplay footage for the title during an Xbox Games Showcase in June 2024.
Another notable title getting the axe is Everwild, a long-gestating new IP from Rare, the revered British studio Sea of Thieves, which Microsoft acquired in 2002. Over the decades, the studio has also produced the original Donkey King Country games for the SNES, the original Perfect Dark for the Nintendo 64, Conker’s Bad Fur Day and the Banjo-Kazooie series.
According to unnamed sources who spoke to Video Games Chronicle, numerous job cuts and a broader restructuring are expected at Rare, resulting in the game’s cancellation. The sources also confirmed reports over the years about Everwild’s somewhat turbulent development, claiming that it had «struggled to nail down a clear direction for the title.»
The game has reportedly been in development for the better part of a decade, being officially announced in 2019, followed by a trailer in 2020. In 2021, reports emerged that development on the game had been «rebooted.»
The other title reportedly put out to pasture was an untitled new MMORPG from Zenimax Online Studios, the creator of the popular MMO Elder Scrolls Online, which has reportedly reached upward of 25 million players since launching in 2014.
Details about what this title was are sparse, with Bloomberg’s Jason Schreier reporting that the game went by the codename «Blackbird» and had been in the works since 2018. Windows Central said in its report about Perfect Dark’s cancellation that Blackbird was once intended to act as a successor of sorts to Elder Scrolls Online.
David Lumb, a senior reporter at CNET, noted how these new developments at Microsoft underscored the recent job instability in the gaming industry, as well as the uncertainty the cancellations are sure to cause among gamers.
«The biggest losses are to the seemingly thousands of people who are out of a job in a tumultuous industry that’s seen record layoffs year over year,» Lumb explained, adding, «The cancellations of big games like the upcoming Perfect Dark and Rare’s next game Everwild are concerning for Microsoft’s next few years of releases, but also to confidence that a game being teased at, say, an Xbox Showcase will end up coming out.»
According to Variety, all games that were shown off during the 2025 Xbox Games Showcase in June will continue being developed.

Razer Handheld Dock Chroma Follows Its Accessories’ Formula: High Quality With a Higher Price
Review: The Razer Handheld Dock Chroma is great for traveling with your gaming handheld, but it’s not the only option.

The Handheld Dock Chroma from Razer is a compact stand and dock for portable gaming consoles and tablets, offering charging and an interface to send your games to a bigger screen. As the name suggests, it includes RGB lighting that’s part of Razer’s Chroma ecosystem. It was announced at CES in January, and it recently started shipping. Is it any good? Well, largely yes, with some important caveats.
What I like about the Razer Handheld Dock Chroma
The Razer Handheld Chroma Dock is well built. It follows the company’s signature trend of delivering high-quality accessories that look great and are reliably durable. The metal build quality is a nice touch against all the other plastic, cheap-feeling options out there. It’s also fairly small, making it easy to drop in a bag as you head out. That’s kind of the point, as Razer designed this dock to be portable, fitting in nicely with the whole idea of handheld gaming in the first place.
One big difference of the Dock Chroma, compared to other docks and which also plays well into the portability aspect, is that the stand to hold the handheld is adjustable. It will lie flat, covering the mounting deck entirely and turning the whole thing into a little cube. Or you can adjust it as steep as 75 degrees to find the perfect viewing angle while gaming.
As the Chroma name suggests, there’s an RBG light strip on the front that syncs up with your Chroma settings. If you aren’t using a device that supports Chroma, there’s a button on the right side you can use to cycle between some preset lighting scenes.
What I don’t like about the Razer Handheld Dock Chroma
The first odd design choice almost flies in the face of the whole portable idea: There’s a USB-C cable sticking out of the back. This is what you connect to your handheld but oddly it can’t be detached or even folded into the dock itself. So it’s a bit clunky from a portability standpoint.
Then there’s the port selection. There’s a 100-watt USB-C port, three USB-A Gen 1 ports, a gigabit Ethernet port and an HDMI 2.0 port. That’s not a terrible port selection for a docking station, but the lack of a second USB-C, DisplayPort or a 3.5mm headphone port is rather disappointing.
Performance
For something that’s essentially a docking station for handheld gaming rigs, the Chroma Dock works well. I hooked it up to a ROG Ally and had no issues at all. It was cool to be able to drop the Ally onto the dock, Switch-style, and instantly have my games up on my monitor and TV. The plethora of ports navigating Windows 11 on the Ally makes it so much easier by letting me use a keyboard and mouse with it.
The Chroma Dock works with any device that supports USB-C, including the Nintendo Switch. Just be aware that it’s kinda awkward with the Switch because you have to set it upside down for it to work, and you’ll need to use the original Nintendo charger that came with it. You’ll also need to provide your own charger for any device you use as Razer doesn’t include one in the box. But for the Switch specifically, you’ll need the Nintendo one.
Technically, you could mount any USB-C device onto the dock, including a tablet or phone, to have an all-in-one sort of situation. If you’re on the go a lot, this might be a game-changer in more ways than one.
Should you get the Razer Handheld Dock Chroma?
If you’re ready to pay the Razer premium, then perhaps. The Chroma Dock will set you back $80, which is more than double the price of most other similar docks. That’s a lot to ask for something like this. But if you want that Razer brand and you have other Chroma lighting gear, it’s well-built, if lacking in some features.
