The factors to consider ultimately depend on what kind of prints you want to make. Also, it is based on whether you’re a beginner or more advanced. So, before you purchase 3D printer filaments, make sure the filament you buy is applicable for all the prints you plan to make.

1. Filament Size And Dimension Accuracy

3D printer filaments usually come in two sizes. These sizes are the thickness of the filament. The two thicknesses are 1.75mm and 3.0mm. Make sure you find out which thickness is required by your FDM printer before you purchase the filament. Each filament is also designed to have maximum dimension accuracy. This means the most of the filament will extrude beyond the instructed layer dimension. For example, if the dimension accuracy is +/-0.05mm, then the filament has a practical accuracy that may vary 0.05mm away from the perfect point of extrusion.

2. For Beginners

If you’re a beginner and ready to enter the world of manufacturing, then buying PLA filaments and/or PET-G filaments will be the best choice. These filaments are the best when it comes to getting acquainted with 3D printing. They  are inexpensive and fairly easy to print with the standard configuration of 3D printers.

3. For Advanced And Professional Users

If you’re pretty advanced or even a professional at 3D printing, then you’ll have a rough idea of what are the best 3D printer filaments for your use. It should be one of these – ABS, TPU, or the more high-end wood, carbon fiber, nylon, etc. ABS and TPU are mid-level filaments that will allow you to print more complicated designs. The more high-end 3D filament materials are harder to print with, and you’ll need the necessary configuration of your 3D printer. 

4. Printing Prototypes And Tools

A very common use of 3D printing is to print prototypes and tools that will help in manufacturing. PLA is great for making prototypes, as it’s just used to show people what the actual design will look like. If you want to print tools that will help facilitate manufacturing, you’ll need something stronger. PET filaments will do, but for more strength and flexibility, a filament like ABS is what you’re looking for. If you need something extremely strong and resistant to high and low temperatures, then carbon fiber is the best 3D filament.

5. Commercial Use

If you’re planning to make prints that are ready for commercial use, then you’ll want something durable and strong. A filament like TPU, or most mid-level filaments are the popular choice. TPU is quite flexible too, so if you need to print something that bends, then this is the best 3D filament. If you want more quality, then you’ll need carbon fiber or any of the more high-end material.

6. High-Stress Properties

Sometimes your prints may need to consider its application in high-stress conditions. The conditions could be its capabilities in high and low temperatures, whether it’s weatherproof, and resistance with chemicals. PP is a filament that can withstand any kind of environmental condition. PP and PA can also resist corrosive chemical substances. Filaments like ABS and PET-G are capable of withstanding high levels of heat. If you’re looking for something water-resistant, then PA and PP are the best 3D filaments.

7. Printer Compatibility And Settings

Every 3D printer filament in the market has a particular printing temperature range, and also a heated bed temperature range. Printing with the material in the recommended ranges of printing settings will give you the best prints. Also, most 3D printer filaments will say that they are compatible with almost all FDM printers. Almost all doesn’t mean all, so make sure the filament you chose to buy is compatible with your 3D printer.

8. Packaging

Different 3D printer filaments have different weaknesses. For example, PLA and most 3D printer filaments can decay when exposed to too much moisture or water in the environment. That is why it is important to see the product’s packaging, as you can most probably store the product in the package itself for the best protection. Most filament spools come in a package that is resealable and great for filament protection. One example of good packaging is an aluminum foil package with a desiccant inside, provided by Overture and other top-rated brands.

Different types of 3D Printer Filaments

1. PLA

The polylactic acid filament is the most popular 3D printing material. PLA is a biodegradable thermoplastic, and it’s derived from renewable sources like sugar cane, cornstarch, and other plant-based materials.

Using PLA for 3D printing is more environment friendly compared to the other plastic materials. It also has low-toxicity features. All this makes it the most popular filament in the 3D printing community.

PLA material doesn’t produce toxic stink during printing, so it is much safer to use within classrooms and homes. It is the best 3D printer filament for beginners.

2. ABS

ABS filament is just as popular as PLA. Although, it’s preferred for users who have some experience. ABS filament is known for its high durability and capacity to withstand high temperatures. It’s tough and impact resistant. Do note, ABS uses high temperatures to print – and that could lead to a warping effect on your prints when they cool. So, be sure to print with a heated bed and a ventilated space.

The filaments are strong and slightly flexible, which will make your prints durable and of good quality.

3. PETG (PET)

PET (polyethylene terephthalate) is the most commonly used plastic in the world. It’s the plastic used to make plastic bottles and covers. Raw PET isn’t commonly used in the 3D printing community, although its variant PETG is increasingly becoming a popular filament.

This filament is less brittle, clearer, and much easier to print compared to PET. It’s a good trade-off for PLA and ABS as it is flexible, durable, and easy to print with.

4. TPU

TPU (Thermoplastic polyurethane) is a plastic filament with rubber-like properties. They are incredibly flexible, and essentially used to make prints that one could wear. TPU is a variant of TPE (thermoplastic elastomers), which is more rigid and also more flexible in cold temperatures. TPU has minimal warping and shrinkage properties. It’s extremely flexible and perfect for parts that compress. Although, it’s a bit harder to print with compared to ABS, PLA, or PETG.

5. Nylon

Nylon, also known as polyamide is a popular synthetic polymer that has extensive use in industrial applications. This 3D printer filament is light-weight, flexible, wear-resistant, and it’s cost-effective. It is the best 3d printer filament for functional and mechanical parts, because of its high melting temperatures and its strength.

A unique feature of nylon filaments is that you can dye it. One can dye it before and after the prints. Although, it absorbs moisture, so make sure you store it in a cool and dry place. It is a great filament to make tools and prototypes.

6. HIPS

High impact polystyrene (HIPS) is a plastic that combines the hardness of polystyrene and elasticity of rubber. It’s commonly found in containers and other protective packaging. In 3D printing, HIPS is used as support structures. As 3D printers can’t print onto thin air, users use HIPS, to make underlying structures to support printing the actual project. HIPS is an excellent support material with ABS for dual extrusion printers.

HIPS is a decent printing material on its own too. It’s stronger and more durable than PLA  and ABS. It can easily be glued, painted, and sanded. HIPS is a good material to make prints that need to endure wear and tear.

7. Wood

Once you become a novice or a professional 3D printer, you might get bored and tired of making plastic prints. Well, now you can become more creative with wood-like filaments. These filaments can be used only in FDM printers. 

Wood filament is not completely wood; it’s a blended mixture of recycled wood and binding polymers. The prints you make will look and even smell like wood.

Using wood filament is similar to using plastic filaments like PLA and ABS. The recommended temperature is 175C to 250C, to achieve the wood-like appearance.

8. Carbon Fiber

When carbon fiber is blended with 3D printer filament like PLA, ABS, nylon, and PETG – the resulting filament is extremely tough and extremely light-weight. The structural integrity of this filament allows prints to withstand a wide variety of applications.

Although, there is a trade-off – and it’s your printer’s nozzle. Printing with carbon fiber increases the wear and tear of your printer’s nozzle. If your nozzle is made of a soft metal like brass, then carbon fiber will definitely damage it. So when you use carbon fiber or other exotic materials, make sure you frequently replace your nozzle, so your prints won’t be affected.

9. Sandstone

Sandstone filament for 3D printing is a great material that’ll offer a unique finish to your prints. Sandstone filament is a blend of PLA and chalk powder, which results in color and texture like stone.

By changing the temperature, you can produce different surface textures to your prints, smooth and rough. For making prints with a sandstone finish, this the best 3d printer filament for the job. The printing temperature range is 165C to 210C.

10. Iron

Iron filament, also known as magnetic iron filament due to its magnetic properties, is made by infusing iron powder into a base material like PLA or ABS. The resulting material is also called magnetic PLA and magnetic ABS. This is a filament that you’ll enjoy printing with. It’s obviously helpful to create prints that need to be magnetic in nature.

11. Metal

Want to make prints that are a little bulkier and shinier? Metal is the right choice. Similar to all exotic material filaments, metal is not completely made of pure metal. Rather, it is a blend of metal powder, with base materials like ABS or PLA. But that doesn’t stop resulting prints from having the metallic look and feel. Even the weight is like metal, as the blend becomes denser with metal powder.

Brass, bronze, aluminum, and stainless steel are a few varieties of 3D printer metal filaments available in the market. For specific looks, you can polish, weather, and tarnish your prints without hesitation. In fact, a little post-print processing can make the print go a long way.

Make sure you replace your nozzle often when your printing with metal, as it wears and tears the nozzle. It increases the size of the nozzle – which then affects your prints. The most common metal filaments have a blend of 50% metal and 50% PLA or ABS, but some have 85% metal composition as well.

What’s Your Choice?

3D printer filaments are available in a wide range of colors and in different types, all with their unique properties. There’s plastic, metal, wood, nylon, carbon fiber, etc. You have all the materials to make your next print exceptional. All these different types come in a range of colors – so your next project will turn out to be exactly how you want it. Just make sure your printer is compatible with the filament material – and you’re all set to print. Any of the above filaments that are suitable for your 3D printer will  change your 3D printing experience.

When it comes to 3D printing filaments, it’s better to go for a recognized good brand, rather than looking at the prices. For most users, especially beginners, it’s best to print with a good quality PLA filament or ABS filament. Both of these filaments are cheaper compared to others, and they are the easiest to print with. They’ll work well with most 3D printing projects.

The biggest challenge you’ll face when buying 3D printer filaments is getting the quality right. Most of the time, ruined prints are the result of low-quality filaments. That is why this guide only includes the best that come at different prices. Some manufacturers provide low-quality filaments at cheap prices. Don’t let that fool you – anything mentioned in this guide is good quality, and it won’t affect your prints if your CAD design and 3D printer configuration are perfect for the project. New filament manufacturers and filament types are entering the market, so don’t fall off the edge of the seat when the next best 3D printer filament releases.

FAQs

1. What Material Should I Use To Print With?

The most common and popular choice of filaments for FDM home 3D printers are PLA or ABS. PLA and ABS are both plastic materials, with good strength and flexibility properties. These are the best 3D printer filaments for beginners and mid-level enthusiasts. LCD home 3D printers use liquid resin, which is also a plastic material that’s used for all beginners and professional LCD 3D printing.

2. What Colors Of 3D Printer Filaments Are Available In The Market?

3D printer filaments come in a wide range of colors. Each manufacturer doesn’t produce every color, but for each type of 3D printer filament, there will be color options available. You may not find color options when it comes to filaments like wood and carbon fiber, but you always have the option to paint them. Glow in the dark plastic filaments are available in the market too.

3. How Much Filament Do I Need To Use For A Print? How Will I Know Whether I Have Enough?

It ultimately depends on the design you want to print. When you design in CAD, you’ll adjust printing settings, like infill density and layer height, which change the consumption amount of the filament. Although for a rough figure, a 1kg spool can print about 9 figures with dimensions of 7 x 5 x 5 cm.

4. What Is The Quality Of The PLA Filament? How Long Can It Last?

Generally, it takes about 6 months for an object made with PLA to show signs of decay, like cracks. But time is not the deciding factor; many other factors come into consideration for the PLA object to decay. If PLA is exposed to too much moisture through air or water, it can get damaged quickly. If it’s at room temperature and under no pressure, the object can endure up to 15 years.

5. Can You Use PLA To Make Cups To Drink Out Of And Plates To Eat On?

This plastic is too soft for hot drinks, and it can melt if it’s extensively used in a microwave or dishwasher. ABS is the better choice if you plan to print plates and cups for you to use. But please note, it is not certified food safe to use these plastics, and these plastics have chemicals that are potentially dangerous if ingested.
