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.

Look Up Tonight to Spot November’s Supermoon, the Brightest Moon of 2025
Has the moon been looking brighter and bigger to you for the past few days? Here’s why this month’s supermoon is even more super.
It’s already a great month for skygazers, with a trio of meteor showers and the return of the northern hemisphere winter constellations. On Tuesday night, it also features the second of four supermoons in a row. This month’s supermoon will happen on Nov. 4-5, and November’s beaver moon is special because it’ll be the brightest full moon of 2025.
In addition to being a supermoon, November’s full moon is known as the beaver moon. There is some debate as to why it was named this way. Some believe that this was the best time of year in the old days to set beaver traps to get pelts for winter clothing. Others believe that it coincides with the busiest part of the year for beavers, who are now stocking their lodges with supplies for the upcoming winter.
Here’s what time it’ll look its biggest and brightest, and what else you need to know about the November supermoon.
Don’t miss any of our unbiased tech content and lab-based reviews. Add CNET as a preferred Google source.
The brightest supermoon: When’s the best time to see it?
The moon will reach peak illumination at 8:19 a.m. ET on Nov. 5, making the evening of Nov. 4 and the morning of Nov. 5 the best times to view the moon.
Since moon phases shift slowly, the moon will appear almost full for nearly a week. If you are unable to view the full moon on its best night due to weather or other reasons, you can still see a mostly full moon at any point from Nov. 3 to Nov. 8.
For all of those days, the moon will be measurably brighter in the night sky compared to any other full moon in 2025. The reason for this is because of the moon’s elliptical orbit. Since it’s not a perfect circle, the moon’s 27.3-day journey around the Earth brings it closer to us on some days, a phenomenon known as perigee. If there is a full moon during this time, it’s branded as a «perigean full moon,» which you may know better as a supermoon.
Not all supermoons are equal, and November’s will be a little more special than others. According to The Farmer’s Almanac, the beaver moon will be a scant 221,817 miles away from Earth, making it the closest full moon of the year. That means it’ll be the biggest and brightest of the year.
In practice, the differences are fairly minor and likely won’t be visible to the naked eye when compared side by side to other supermoons. A supermoon is only about 7% larger than a regular full moon. According to NASA, the biggest difference is when comparing a supermoon to a micromoon, where a supermoon will be about 14% larger and 30% brighter. So, if you notice that your backyard patio is lit up more than usual, it’s because of the supermoon.
Also due to the moon’s orbit, November will also bring a micro new moon, which means the moon will be as far away from the Earth as it can get — a phenomenon known as apogee. November’s new moon occurs on Nov. 20, but you won’t be able to see it.

Stay Informed About Your Flights This Holiday Season With Your iPhone’s Tracker
Your iPhone is hiding a flight tracker. Here’s how it works.
Thanksgiving is only a few short weeks away and if you plan on flying during the holiday season, keeping up-to-date on changes to your flights is crucial. Airports can be hectic during any holiday, but with the government shutdown continuing, flights are liable to change or be cancelled more often.
Luckily, it’s never been easier to get up-to-date information about your flight. For starters, your airline probably has an app, and if not, you can check its website. If you’re in a hurry, you can Google the flight number. Or you can just use your iPhone’s built-in flight tracker that’s sneakily tucked away.
That’s right: Your iPhone has a flight tracker that you may have never known about. It’s there for when it’s needed. Below, we’ll show you have to access it in not one, but two places, so you never have to go hunting for your flight info elsewhere again.
Don’t miss any of our unbiased tech content and lab-based reviews. Add CNET as a preferred Google source on Chrome.
For more on the iPhone, check out everything Apple announced at WWDC 2025.
How to track your flight via iMessage
Before we start, there are a few prerequisites you must meet:
- Make sure iMessage is enabled (it doesn’t work with SMS/MMS).
- You’ll need your flight number somewhere in your text messages, whether you’ve sent that information to someone (even yourself) or it’s been sent to you.
- The flight number must be sent in this format: [Airline] [Flight number], for example, American Airlines 9707.
Launch the native Messages app on your iPhone and open the text message thread that contains your flight information. You’ll know the flight tracker feature works when the text with the flight information appears underlined, which means it’s actionable and you can tap on it.
If your flight is still several months away or it’s already passed, you might see a message that says, «Flight information unavailable.» You might also see another flight that’s not yours because airlines recycle flight numbers.
You can check your flight status from Spotlight Search, too
If getting your flight information from Messages wasn’t easy enough, you can also grab the details right from your iPhone’s home screen by swiping down and adding your flight number into Spotlight Search. Even better, this works with Spotlight Search on your Mac computer, too.
How to access the hidden flight tracker
Although the airline name/flight number format highlighted above is the best way to go, there are other texting options that will lead you to the same result. So let’s say we stick with American Airlines 9707, other options that may bring up the flight tracker include:
- AmericanAirlines9707 (no spaces)
- AmericanAirlines 9707 (only one space)
- AA9707 (airline name is abbreviated and no space)
- AA 9707 (abbreviated and space)
I would suggest you keep the airline name spelled out completely and add a space between the two pieces of information — like in the previous section — because for some airlines, these alternative options may not work.
Real-time flight tracking
Once everything is set, tap on the flight information in your text messages. If the feature works correctly, you should see the following two options appear in a quick-action menu:
- Preview Flight: View the flight’s details. Tap this to view more information about the flight.
- Copy Flight Code: Copy the flight code to your clipboard (in case you want to send your flight details to someone else via text or email).
If you select Preview Flight, at the top of the window, you’ll see the best part of this feature: a real-time flight tracker map. A line will connect the two destinations, and a tiny airplane will move between them, indicating where the flight is at that exact moment.
Underneath the map, you’ll see important flight information:
- Airline name and flight number
- Flight status (arriving on time, delayed, canceled, etc.)
- Terminal and gate numbers (for arrival and departure)
- Arrival and departure time
- Flight duration
- Baggage claim (the number of the baggage carousel)
If you swipe left on the bottom half of the flight tracker, you can switch between flights, but only if there’s a return flight.
