Best Filaments for 3D Printing
(Image credit: Tom's Hardware)

If you're printing with an FDM-style 3D printer (the most popular and user-friendly type), your printer feeds a roll of plastic (or other material) filament through a hot extruder and then deposits it on the print bed in layers. You can have one of the best 3D printers or the best budget 3D printers on the market, use all the right settings in your slicer, and still end up with a print failure or ugly output if you don't use the right filament. 

The best filaments for 3D printing can not only provide good adhesion and avoid clogging your extruder but also build models with eye-popping colors, sharp details, and strong durability. Filament rolls are available in a virtually limitless array of different colors, including rainbow and translucent.

Fun fact: We easily used up to $800 worth of filament in our recent review of the massive Elegoo Orange Storm Giga. Not surprising for a machine with a build volume of 800 x 800x 1000 mm for sure. It's not a machine for everyone, but if you are looking to make toddler-sized prints, you should stock up with the best filaments and go to our best 3d printer deals to see great discounts on materials. Check out our Giga review for performance details and to see all the fun prints we created.

We’ve burned through cases of filament on dozens of printers using both Bowden and direct drive extruders to help you find the best filaments for 3D printing in the form of PLA, PETG, and TPU materials. A summary of our picks is below, followed by a detailed list with photos and specs for each recommended filament.

Filament Types

There are many different materials -- mostly types of plastic -- that you can get, but there are three major varieties.

  • PLA (Polyactic Acid), also sometimes combined with other materials and called PLA Plus, is the easiest to print with and most popular, but it isn't the strongest, and it can be brittle.

  • PETG (Polyethylene Terephthalate modified by Glycol) is stronger and a bit more flexible, but it can be stringy if you don't dial in your settings correctly.

  • TPU (Thermoplastic Polyurethane) is a rubbery, flexible filament that usually requires a direct-drive printer that can hit high temperatures. 

Best PLA Filaments

The best filament type for most people and projects, PLA (polyactic acid) is usually inexpensive and easy to print, which is why it’s also the most popular material. PLA filament runs on any 3D printer with any kind of bed surface and doesn’t require an enclosure. Made from renewable organic sources like corn, beets or sugarcane, PLA is more environmentally friendly than oil based plastics and doesn’t have very harsh fumes. 

Most PLA is somewhat brittle and has a low melting point, so it’s best used for decorative objects not subject to high temperatures or too much sunlight. It sands well and is easy to paint, making it great for costume pieces.

Looking for a bargain? JAYO has you covered with easy printing and affordable PLA Plus. PLA Plus is stronger than normal PLA, and can be used in practical prints that aren’t exposed to high temperatures or let sitting outside – like toys and storage boxes. This giant nozzle was used to test a Sovol SV07 running Klipper and was printed at a brisk 250 mm/s without issue. 

The spool was neatly wound on recycled cardboard, with a pair of holes punched in the side of the spool makes it easy to tuck away the loose ends of your filament.

Jessie Premium PLA is a smooth printing filament manufactured by Printed Solid in Newark, DE. I’ve been a big fan ever since the Dumpster Fire incident of 2020 when I printed hundreds of Dumpster Fire Christmas ornaments for friends and family in Jessie’s Tree Green and Mystery Orange. 

You can select from a palette of 38 colors, each packaged on sturdy cardboard spools with steel cores for a friction free spin. Care for sparkles? Filament with micro glitter is only a dollar more than the regular versions. Spools are well labeled and made of sturdy chipboard with a steel core that helps lower friction while still being fully recyclable. Fun fact: the Jessie line is named after CEO David Randolph’s dog.

More expensive than ordinary Polymaker 

Announced this year at the Rocky Mountain RepRap Festival, the Starlight series of Polymaker filament is an eye-popping line of shimmery metallics. The filaments have a color shifting property that makes their colors hard to peg down, but have a lush metal tone. The glitter is very finely ground to avoid being too abrasive on your hotend.

Polymaker spools are always neatly wound on recycled cardboard, with a several well spaced holes punched in the side of the spool makes it easy to tuck away the loose ends of your filament.

Anycubic has introduced a line of filament to accompany their printers, starting with a pallet of basic colors. One stands out though: Blue Metal, a beautiful silk PLA with an interesting luster that shifts the filament from blue to steel gray. The material prints smoothly and does a great job of hiding layer lines. 

Anycubic’s filament prints well on all FDM printers. The spools are made of dense cardboard with holes for tucking the end of your filament, though there’s practically no labeling.

Cookie Cad makes some amazing colors, and their gradient blends are among our favorites. Gradients slowly blend complmentary colors together, similar to a rainbow PLA, but with only three colors. Mermaid is Purple - Blue - Green, Unicorn is Pink - Blue - Purple, Sunrise is Pink - Orange - Yellow and Sunset is Dark Blue - Purple - Pink. 

Cookie Cad’s gradient blends are perfect for making dragons and other decorate containers where a slow color shift can be optimized.

This super fast, silk rainbow PLA only needs about 5 meters per color change – a third less than other brands. Still, that’s a lot of filament, and this Correlation Vase from Clockspring3d’s Patreon only shifted through three of its delicious dark metallic colors. 

Mika3D sells this color in three batches of 500g spools, leaving you with awkward amounts of filament at the ends of each spool. The spools are well labeled, but are plastic, which causes unneeded waste.

This line of glittery rainbow PLAs make super fun prints that transition through 3 to 5 colors, depending on which version you purchase. The shimmery additive is non-abrasive and makes layer lines melt away for extra smooth prints. As with most rainbow filaments, you’ll need to use a lot of filament to see the color changes. It takes about 15 METERS between colors. This Crystal Dragon took over 56 meters of filament and just got into the third color of a Blue/Purple/Green spool.

Locyfens uses clear plastic spools, which is nice for seeing how much filament is left on the reel, but inconvenient once the filament finished. They are well labeled and have good spots for managing the filament tails.

15 meter average between color changes 

Inland makes three Rainbow filaments: Silk Rainbow, a pastel Rainbow 2 shown here, and glow in the dark Luminous Rainbow. Each filament uses Inland PLA as the base. As with most rainbow filaments, you’ll need to use a lot of plastic to get several color changes. 

It takes about 15 meters between colors. This CHEP Cube was printed at 600% with thick walls and weighs about 300 grams and just barely makes it through all the colors in a spool of Rainbow 2. Inland’s rainbow filaments are currently spooled onto clear plastic master spools – which means they can be refilled with Inland Spooless once they are used up.

Inland jumped into the dual color game with it’s own line of silk PLAs. Inland’s dual colors mix more than other brands, so the color shift is more subtle, like mixing pastels chalks. 

Inland’s two color silks comes in 10 color combinations. A direct drive extruder handles it better, though Inland seems to twist less in the extruder and produces an even effect.

Is it blue or is it green? It’s both! Matterhackers was the first company to introduce the 3D printing community to dual color filament – filament that has two colors running side by side on a single strand of plastic. The colors do an interesting dance that causes color shifts depending on your viewing angle. 

Quantum is a silk PLA that comes in 12 color combinations. It works best on a direct drive extruder, which keeps the filament from twisting on its way to the hotend. Quantum is delivered on well labeled plastic spools, which are great for seeing how much filament is left on your spool, but leaves you in a trash quandary when the filament is used up.

You’ve seen dual color filament – now you can print THREE colors all at once. Tri-color filament has three colors running side by side by side on a single strand of plastic. This results in a shimmering, almost iridescent shine as the three colors mix. 

Tricolor is a silk PLA at its heart, and runs better when hot. It also benefits from the straight path of a direct drive extruder, which keeps the filament from twisting on its way to the hotend. OVV3D delivers its filament on well-marked, heavy chipboard spools that can be recycled.

Protopasta HTPLA is one of my favorite materials for 3D printing – it always runs smooth, trouble- free and without obvious layer lines. Sparkly colors use extremely fine micro glitters to avoid being abrasive to your nozzle. Even better, many of their specialty colors are concocted by visitors to the factory’s Filament Making Workshops. This dragon flexi was printed in my favorite color, Joel’s Highfive Blue. 

There’s 22 Community Inspired Colors, which have always been spooled on 100% recyclable cardboard. The spools are well labeled, but they lack holes for tucking in the tail of filament – we’ve used tape or simply jabbed the end into the spaces in the corrugated cardboard. Manufactured in Vancouver, WA.

ReFuel is quality recycled PLA filament made from 3D Fuel’s in-house manufacturing waste. Leftover scraps from all their PLA colors are mixed into one giant batch, resulting in spools of brownish gray to earthy black material that looks a bit weird but prints just as wonderfully as the first batch. 

The colors can be a bit inconsistent, so ReFuel is best for functional prints or models you intend to paint. Spools are packaged in a plain box with no labels to save on cost. 3D Fuel has factories in both the US and Ireland.

Would you believe the company known for lux PLA is also the source of the most affordable recycled filament we’ve found? ProtoPasta’s Recycled Black PLA comes from their own manufacturing waste, so every roll of recycled filament is just as smooth printing as ProtoPasta’s first run colors.

Black Recycled is a blend of scraps from their many shades of black and other darker shades mixed together. It’s not considered a heat treatable filament due to the random nature of the mix, but you might find a bit of sparkle in this very rich, dark black PLA. The corrugated cardboard spools are well labeled, but they lack holes for tucking in the tail of filament – we’ve used tape or simply jabbed the end into the edge of the spool.

ProtoPasta’s more colorful line of recycled PLA filament is great for everyday prints with that premium printing experience only ProtoPasta can serve up. The company collects scraps from their own waste stream and keeps it sorted by color group. The clean waste plastics – filament that’s out of spec or color transitions – is ground back into pellets and blended into new recipes with muted colors. The Calibration Castle above was printed in Still Colorful #11. 

The results are unique, and the filament has similar print quality to first run materials for a (slightly) discounted price. ProtoPasta’s corrugated cardboard spools are well labeled, but they lack holes for tucking in the tail of filament – we’ve used tape or simply jabbed the end into the edge of the spool.

PolyTerra comes in 26 velvety and pastel colors, with a matte finish that does well at hiding layer lines. It’s extremely easy to sand and paint. It’s a good quality, low cost filament for people who want to be environmentally-friendly makers without switching to a recycled filament. The flexi dolphin above was printed in PolyTerra Sapphire Blue PLA.

Many filament companies have switched to cardboard spools to help with recycling, but PolyTerra does one better. Not only is each cardboard spool and package made from recycled material, but PolyMaker contributes to OneTreePlanted.org so that every spool purchased plants a tree in your region. The spools themselves are very sturdy chipboard with well placed holes to help tame the filament’s tail. PolyMaker is a global company with an office and warehouse in Houston, TX.

ProtoPasta’s metal-filled PLA is a mix of standard PLA mixed with real metal powders. This makes it very abrasive and a bit finicky to print so you’ll need to use a bigger nozzle and slower speed. Iron filled, shown here, is the most affordable of Protopasta’s metal line up. All the metal filaments can be polished to a shine, but iron can be rusted for an old, worn look. 

There’s also steel, copper, bronze and brass filaments. Remember to factor in the weight when making your purchase, as filament is sold by weight, not length. These filaments are heavier than straight plastic so you get less filament per spool. This iron Benchy weights 17g, while a pure PLA Benchy weights 12g.

Buzzed Beer PLA is a fun novelty filament made with 10% organic fibers left over from the beer making process. It has a deep golden brown color with tiny dark flecks, yet is not considered an abrasive filament. It's great at hiding layer lines, has little stringing, and prints easier than wood based filaments with a similar natural color. We’re calling this one a “novelty” filament because it only uses a small portion of recycled materials, it’s difficult to find in stock and has a premium price. 

3D Fuel still uses plastic spools, which is inconvenient once the filament is used up. They are well labeled and have good spots for managing the filament tails. 3D Fuel has factories in both the US and Ireland.

Entwined is a beautiful filament with a natural, almost translucent, earthy wood tone derived from hemp. It’s premium PLA mixed with natural hemp fibers that prints with less noticeable layer lines and little stringing. We’re placing this one in the “novelty” category because it only uses a small portion of recycled hemp fiber, it’s difficult to find in stock and has a premium price. It does, however, print really well and makes a smoother printing alternative to wood PLAs. 

3D Fuel still uses plastic spools, which is inconvenient once the filament is used up. They are well-labeled and have good spots for managing the filament tails. 3D Fuel has factories in both the US and Ireland.

Best PETG Filaments

PETG (Polyethylene Terephthalate glycol) is an oil based plastic that’s less brittle than PLA. It’s more resistant to high temperatures and sunlight, making it more suitable for outdoor parts or prints used inside a car. It's easier to recycle than PLA, resulting in many brands of 100% or partially recycled PETG filament. 

It can be a little harder to print than PLA, is often stringy, and is more difficult to sand and paint. For best results, PETG should be kept in a sealed bag or airtight box to reduce moisture exposure.

PETG can be printed with any 3D printer, any bed surface and does not require an enclosure. It does print hotter than PLA, but not so much as to require an all-metal hotend. PETG will bond with glass and sticks entirely too well to PEI coated print surfaces. You will need to use a layer of gluestick as a release agent – which is somewhat counterintuitive, but definitely works.

Best TPU Filaments

Whether you’re making toys that can withstand hard play or functional prints that take a beating, TPU (Thermoplastic Polyurethane) is a great choice. TPU isn’t brittle like PLA and has a rubberlike quality that makes for good handles, phone cases and even gaskets. You can make your parts softer or harder by adjusting the number of walls and level of infill – 10% infill for squishy prints or 50% infill for firm rubbery prints. It’s also not as UV sensitive and can be used for outdoor parts. 

TPU is an extremely soft filament that works best with a direct drive printer. Using a Bowden style extruder is not impossible, but it is much like pushing a wet noodle into your hotend. It needs to print at a higher temperature than PLA, but doesn’t need an all metal hotend or enclosure. Any bed surface will work with TPU, but you will find a layer of glue stick to be helpful for removing prints. 

TPU also needs a slower printing speed and very little retraction. Stringing is almost unavoidable, so it's best to keep this filament very dry and avoid models with a lot of travel moves.

Its shore hardness is typical for TPU at 95A, meaning it is soft and flexible like a flip-flop or perhaps a tire. Of course this all depends on how thick you make the walls and infill. Our sample print used 2 walls and 10% infill, turning the Thwack Hammer into more of a Clown Hammer.

Cheetah TPU has a shore hardness of 95A making it very soft and flexible, yet NinjaTek claims it can print twice as fast as normal TPU. Hence, the Cheetah moniker. We tried running it at 60mms – as suggested by their website – and only got jams, even with a direct drive. 

Slow and steady is still the way to go when you’re printing filament with the properties of a wet noodle. Our Fire Red OG Rocktopus was run at a more conservative 40 mms and turned out pretty nice with a little stringing that was easily trimmed off.

    It's completely baffeling that a cheap "cardboard spool" is a pro and better "plastic spool" is a con.

    First: cardboard holds moisture and degrades in shipping, meaning your brand new vacuum-sealed filament can arrive wet and dusty.

    Second: it's just outright nuts to me that somebody buying materials for an inefficient and highly wasteful plastic manufacturing process would be morally opposed to using plastic or creating plastic waste. These things aren't even bulk packaged. To 3D print, you need to buy piles of individual rolls, each with its own vacuum bag and packet of silica gel, put into a roll sized box, that's put into a bigger box before being shipped halfway around the world to your doorstep.

    There's nothing "green" about 3D printing, and there never will be. Any attempt to convince you otherwise is a brazen marketing gimmick spoken from the mouth of a salesman. It's a hustle. They may as well be a used car dealer trying to sell you the benefits of organic, locally-sourced, farm-to-table gasoline.
    If you're not comfortable with waste or throwing away plastic, then maybe learn how to whittle instead?

    Glass-half-empty kinda guy right there.
    I really love the logic of "we can't reduce the impact on the environment to zero, so we should just not care at all." It's like saying "the catalyst in the car doesn't reduce the emissions to zero, so we should just remove it and all filters." While yes, a gas car will never emit fresh air, we should still try to reduce emissions as far as possible, or else we'd have many more problems much faster. Unless you love breathing in the thick black smoke.

    PLA is a bioplastic. It's created from plants, that consume CO2. When you either compost or burn PLA, you're only putting back the CO2 to the atmosphere the plants took out of it. The same goes for cardboard, and many manufacturers even use recycled cardboard. Other plastics, such as those the spools are made from, are made from fossil materials that used to be underground as oil. We pump that to the surface, turn it into plastic and burn it, now we've added CO2 to the atmosphere that wasn't there before.

    By the way, cardboard spools are usually more expensive to manufacture than plastic spools. But where I live, cardboard is cheaper to dispose of than the kind of plastic spools are made from. I haven't had any issue with cardboard spools so far, no damaged spool, no wet filament. The only time a print failed because a spool got stuck was on a plastic spool.
    3D-Printing will always use up some resources, but there is still a large difference between using fossile vs. renewable ressources. And even if we can't reduce the amount of fossile ressources to zero, we can still try to reduce them as much as we can instead of trying to burn limited ressources as fast as we can.

    I have to disagree with a "con" of a plastic reel. After wasting 2/3rds of a reel of PETG with nothing coming out good because of underextrusion, I through the crap out. The problem? Cardboard reels. When the Inland filament was wound, it was wound so tight that the cardboard gave way and the layer got wound below multiple other layers. When the printer attempted to unwind the reel it couldn't pull it out and caused under-extrusion as well as complete stoppages. I nearly pulled my dryer off of the top of my printer when I gave the filament a pull to un-stick it.
    Which gets to a second reason I don't like them. They don't stay round. To play it safe you can't let them sit in your dryer and dispense from it. You have to use the center whole as the reel either wasn't very round to start with or went out of round over time, sitting in the dryer and/or heat.
    Third, after this I built a winding/rewinding device ( listed here: https://www.printables.com/model/407688-bambu-lab-p1-x1-x1c-x1cc-filament-spool-switcher-w ) and I rewind my filament before using it if it is a cardboard reel.
    I specifically look for the plastic reels and I'll buy them over the Greta hugging, tree hugging cardboard lovers. :)

    Spot on. I saw your post after posting. When I saw the "Con" of a plastic reel I immediately lost it. Children with their wishful thinking rather than experience with their cardboard crap.
    If you think that green is the way to go, look at every TPU reel and the mfg'rs know better than to wind this until cardboard waste.

    An interesting comment about Polyterra filament being "slightly heavier". What you are telling us is that you get less filament than others because reels are sold by weight. Did you measure the weight of these or was this a simply observation?
    I've wondered sometimes about how much actually filament is in different reels. I'm convinced that you get a lot less milage out of a 1kg reel of PETG than that of PLA. But how much?
    Now that would be a good article.
