The Best Wood Filament for 3D Printing

If you’ve gotten bored with thermoplastics and are looking for a new way to experiment with your 3D printer, wood filaments are a great direction to take.

These are filaments that mix wood pieces together with a more conventional 3D print filament such as PLA filament so the wood can be manipulated like more flexible filaments despite its inherent rigidity. The mix is usually about 70% polymer to 30% wood fibers, and you can buy spools of it just like any other filament on the market.

They’ve been around since 2012, beginning with polymers mixed with sawdust, but those resulted in products that looked more like cardboard, so the filaments quickly evolved.

Here’s a quick summary if you are in a hurry…

Wood filaments give your finished object the look, feel, and even smell of a wood carving, complete with the grain and color fluctuations you see in the hearts of trees. They take on the properties of whatever wood you use as well, such as the extra sturdiness you may be looking for beyond plastic.

One type of wood filament contains a piece of coconut mixed in with the wood, which gives the finished product a distinct look that you won’t be able to find anywhere else.

3D Printing Wood Filament

If you don’t like the finish you end up with, it’s just as easy to stain your 3D project with whatever wood varnish you want as it is to stain your coffee table, bookshelf, or any other object made of pure wood. You can also sand down rough edges or printing mistakes or carve finishing details with a knife or wood burning kit; the possibilities are vast and don’t end once you turn off your printer.

How to Work with Wood Filaments [3D Printing Wood]

However, wood filaments are not for those who are new to 3D printing. Wood filaments are finicky to work with and require much more manipulation and monitoring than entry-level thermoplastics. A wooden filament will reward you with beautiful, unique objects, but first, you have to learn how to treat them:

  • Use a larger extruder nozzle to 3D print. The recommended size is 0.3 mm or larger, which helps the dark chunks in the wood filament flow through without clogging up. This may result in larger layers than you want, but you can sand down the product until its finish is as smooth as you want, so don’t let that keep you from heeding this advice.
  • Remove the filament from the printer when you’re not using it. The wood filament can burn if left unattended in a printer nozzle that hasn’t cooled down yet, or stopped for some reason, and this will result in a nozzle clogged with blackened, hardened wood. If you’ve already learned this lesson the hard way, run a cleaning filament through your extruder. They’re easy to find and inexpensive, a must have if you’re going to work with wood. Just in case.
  • Find the right temperature. A lot of 3D printing enthusiasts manipulate the finish of their wood filaments by using a higher temperature than recommended for printing. The higher the temperature, the darker the wood, but that’s because the higher printing temperature is essentially burning the wood as it goes through the extruder. There’s a very fine line between a different finish and a burnt filament, so only attempt this if you have the time, patience, and knowledge to do it safely. And if you’re worried, print at the recommended print temperature, then paint the finished object with whatever color stain you want. No fire hazard necessary.
  • Use fast printer speed and high layer heights. Yes, these steps will result in more wobble on the Z axis and chunkier layers than you might want, but they’ll keep your wood filament moving through the extruder. Less time in the extruder means less of a chance for the wood to ignite, and less of a chance you’ll have to clean up that mess. Just make sure your printer is secured for as little frame movement as possible, and sand down any layers that don’t meet your standards.
  • Use higher retraction. Wood filaments and wood material are runnier than normal PLA when they are flowing through the heated larger nozzle. This will lead to material drag if you don’t adjust how fast the material comes out of the extruder, so make sure you adjust to the recommended retraction setting rather than leaving it as it was from working with the previous material. Retraction speed and distance will both make a difference.

Types of Wood Filaments

Now that you know what to look for, let’s talk about the varieties of wood 3D printer filament that are out there. There are three general varieties available:

  • Regular woodfill is the basic variety that is polymer blended with pieces of traditional varieties of wood fiber and wood particles such as oak, maple, or birch. It has the scent and visual properties of the dominant wood variety blended into it, and although it does smell burnt when you 3D print with it if you’ve got your temperature settings correct it will be a stable material throughout the printing process.
  • Bamboofill. This is a polymer blended with bamboo wood fibers, which is more sensitive to temperature and extruder clog than standard woodfill. This means you’ll have to make sure you clean your nozzle thoroughly before and after every print with bamboofill, and you won’t get as wide a color variety as with regular woodfill, but you’ll be rewarded with a smooth print endowed with the flexibility of its blended wood.
  • Corkfill is slightly porous and a much darker color than bamboofill or regular woodfill filament. It has the finicky properties of bamboofill while letting you print something more lightweight and rigid at the same time.

Wood Filament Companies

Finally, it’s time to choose where you want to buy your woodfill for 3D printing wood. There are a number of companies that put out quality wood filament for 3D printing (approved 3D printing filament). Here are our favorites:

  1. Timberfill. These woodfill 3D printing filaments are made of 100% biodegradable sources, which means you’re doing something good for the planet while leveling up your hobby. Timberfill also gives you a relatively large selection of wood colors. You can pick from cinnamon, light wood tone, rosewood, and champagne, all of which display natural variations that you can mix and match to your content. This filament is more expensive than most of the others you can find at $51 per spool on MatterHackers here, but its variations and environmental friendliness makes it worth it.
  2. Laywoo Filaments. The OG of woodfill, literally – this German company’s founder Kai Parthy invented wood filament for 3D printing in 2013. Lay Filaments sells a light cherry type, which means you can experiment with temperatures to create different colored finishes. It also sells a flexible wood filament that’s one of a kind and super useful for those who are just starting out with wood filaments since there’s more give to work with. You can find these filaments on MatterHackers here for around $35, but realize that they’re sold in bundles that are less than standardized full spools. You’ll get about 100 grams from most sellers, so do some math to figure out if that will really be the best bet for you.
  3. ColorFabb. This company based in the Netherlands offers standard woodfill, bamboofill, and corkfill; ColorFab’s strength is its variety on offer. One spool of woodfill from them costs $49.99 at MatterHackers here, but the quality you’ll get makes it worth it. However, keep in mind that ColorFab’s woodfill filaments are not for beginners. Their high quality and relative expense mean you want to be sure you know how to deal with the unique problems of woodfill before you buy any.
  4. MG Chemicals. These guys use poplar for the wood particles in their wood filaments, about 25% mixed with PLA (a hybrid wood PLA). Poplar wood particles are larger than other wood filaments, so make sure you have a nozzle that can open to 0.4 mm to prevent any clogging. If you burn up any filament in the extruder, it will be harder than usual to scrape out because of the size of the popular pieces. This is a great woodfill to start with. It’s as sturdy as any other standard wood filament while being as much of a bargain as its thermoplastic cousins ($31.45 per spool), and MG Chemical gives you free shipping if you buy a few spools at once. So stock up on whatever filament you need, and throw in a wood filament spool for fun to see how it works for you. Check out the latest prices on Amazon.
  5. HatchBox. This company has quality control on lock. That means their wood filaments are less likely to clog your extruder because they have gotten the tolerance down to +/- 0.01 mm from the expected diameter; so the filament you buy will all be within a hundredth of a millimeter of the advertised diameter. This is crazy good compared to the standard +/- 0.05 mm tolerance. So if you’re looking for a material that can be more forgiving of your mistakes because they don’t tolerate their own, try out Hatchbox wood filament. Their wood filaments go for $34.99 per spool (check latest prices on Amazon here).
  6. EasyWood. This company has even more options, in willow, pine, olive, ebony, cedar, birch, and even coconut. These boast a 40% wood particle content, and if you can’t decide which one you want to start with, there’s a sample pack you can buy for $18.01. Full spools of EasyWood varieties are $31.13 (check latest on Amazon here), making them a good bargain for any projects you want to experiment with.
  7. AFINIA. These guys offer a major bargain wood filament. It costs $15.99 per spool, and it’s available at the Home Depot, so if you’re looking to get started with wood 3D printing right away, you totally can. It may not have the array of variations some of these other brands do, but it does have great customer reviews, and it comes in 200 g spools, so we’re naming this one best value.
  8. Hestay. This company only has one finish of wood filament, but it comes in three different diameters: 1.75 mm, 2,85 mm, or 3.0 mm. While 1.75 mm is the recommended diameter for beginners, if you’re brave and/ or know exactly what you’re doing, experimenting with larger filament diameters can give you some unique results. Just make sure you have an extruder that can handle the larger ones if that’s what you get. These spools are $42.29 and come from the Netherlands.
  9. Torwell 3D. Want to save the planet while 3D printing? Torwell uses recycled wood as 35% of its blended filaments. The other 65% is high-grade PLA, and that ratio results in an easy, smooth 3D printing process. You can choose either 1.75 mm or 3.00 mm with the confidence that both will act the same for you. This company is based in Australia, so if you don’t live near that part of the world you may have to wait out a slightly longer than average shipping time, but according to their customer reviews, Torwell works hard to make sure that doesn’t become a major issue. Just remember they can’t make the clocks go any slower, order in plenty of time for your project needs, and enjoy their great customer service if you need anything from them.
  10. RS Pro. These folks sell a filament in “tropical wood” color. What does this mean? A small but noticeable spectrum of variation speckles that translate from the spool to your finished object without detracting from the overall shade. If you can’t picture that, think of how tree bark is almost never all one uniform color; this woodfill reflects that beautifully. It’s $20.75 per spool and acts like your standard other wood blend filaments, so check out this variety for subtle depth to your finished color.

Final Thoughts on Wood 3D Printers
