Buying Guide

Best 3D Printer Filament Buying Guide

Even though the above list of best 3D printer filaments shortens your buying options, you still need to narrow down your choices to one product that you’ll buy. When shopping for the ideal filament, it’d be best to go through the many features such as material, diameter, and type before making the purchase. These factors will help you know exactly what you need and why you need it. They include:

Filament Diameter

Fused Deposition Modeling 3D printers are standardized into two main sizes, 1.75mm and 2.85mm. That means you have to know the diameter of filament that will fit in your model. Is it 1.75mm or 2.85mm? Consult your user manual, and if not available, check-in with your manufacturer to know the exact diameter. Use the data to reference the product specs to make sure you’re buying the correct size.

Filament Type

filament printing

FDM 3D printer filaments are of various types. The market is flooding with all these types, and you must be sure of the best kind that suits your needs. So, the best place to start figuring out what you need is to understand your printing requirements.

While some filament types have similar characteristics, others are different entirely. The most common five include:

PLA: Polylactic acid has become a popular 3D filament-making material because of being economically produced and from renewable resources. It’s biodegradable and easy to use. What’s more, it is relatively durable, and most of the time, it doesn’t require a heated hotbed. It’s biocompatible with the human body – it doesn’t leave serious side effects. It’s also very flexible and shatterproof, but it becomes soft at 50.

ABS: This printer filament is more durable and flexible than the PLA. It’s also relatively heat resistant and boasts a robust build. However, it does require a heated bed, and its temperature requirements extrude 225 degrees Celsius. What’s more, it’s considered less expensive, petroleum-based, and non-biodegradable plastic that produces many fumes when printing.

PETG is an extra-rigid 3D print material with extremely high strength and can achieve sturdy and durable prints. It’s a perfect alternative to PLA and ABS, offering improved strength and lower shrinkage, not forgetting a smoother finish. What’s more, it is UV resistant, meaning it won’t degrade if leave it out in direct sunlight. Another thing, it is water-resistant, allowing you to store it in liquids or submerge it without degrading.

PVA: Polyvinyl Alcohol filament is mainly used with printers with multiple extruders and supports objects that don’t have layers below them. The downside of this 3D printer filament type is, it requires special storage conditions. It is also costly and difficult to source.

What you want to look for here is strength, flexibility, durability, and ease of use. All the above types are the most commonly easy to use and relatively durable filaments. But if you’re looking for high-level printing, go for Nylon, TPE, and TPU filaments as they are highly durable, flexible, but difficult to print.

Filament Grade

3D printer filaments come in various grades, such as 2003D or 4043D for the PLA filaments and PA-747 for the ABS filaments. If you’re a beginner in 3D printing, understand the grading system and pick a model with a grade specified on its specs. Otherwise, you can buy any filament that meets your other requirements and be good with it.

Filament Printing Conditions

Check the material used in making the filament and understand its printing conditions. Some require high-level ventilation; some require time to dry, while others require a high or low-temperature environment. The PLA material is the best if your working area is poorly ventilated and has relatively low temperatures. You can increase these conditions a bit to use the PETG filament, however, avoid the ABS filaments as it can easily crack under them.

Moisture & Storage Conditions

Some materials are highly hygroscopic – they absorb water and become bristle, a state which makes them easily breakable. ABS is such filament that it will require extra resources to store it. The same goes for PLA. However, PLA+ takes in moisture slowly and doesn’t bristle if stored properly.

You don’t have to worry much about the PETG when it comes to moisture, but dust can easily compromise it. So, understand the storage requirement and compared it with your storage facilities to make sure you’re buying a product that won’t make you sweat to find a place to store it after use.

Frequently Asked Questions (FAQs)

Which filament is best for 3D printing?

The best 3D printing filament is the Polylactic Acid (PLA) filament. It’s arguably the most accessible, inexpensive, easy to use, and safe material. It’s a biodegradable material made economically renewable resources. Apart from these, it’s flexible and highly reliable compared to ABS. That might be the reason it’s considered the king of 3D printing filament.

What is the best filament size for 3D printing?

1.75mm print size is the best as it produces finer details if you’re after reliability and extruder efficiency. It’s also perfect for smooth, flexible printouts.

What is the best nozzle size for 3D printing?

The best is a 0.5mm nozzle as it’s a hardened nozzle ideal for all types of 3D printing, including if you’re working with composite materials, metal, and carbon fiberglass. The brass nozzle that comes with the 3D printer doesn’t last long and might bore out to larger sizes precisely after few printing tasks.

What is the difference between PLA and PLA+?

PLA is a hybrid of PLA. It’s more flexible and has fewer brittles. What’s more, it doesn’t snap easily under pressure, thanks to its impressive flexibility. It’s made from materials used in making PLA but mixed with other additives such as fiber and plastic to make it more robust yet flexible.

Conclusion

3D printer filament is the most critical component in 3D printing. These filaments come in different colors, shapes, and sizes, allowing you to use the printer for various projects.

There are many different reasons why I love using 3D printer filament. It’s cheap, easy to find, and comes in a wide range of colors and types.

More and more 3D printer filament buyers spend almost a whole day searching for a reliable and helpful filament for their projects. But that doesn’t have to happen to you. The information you’ve read here will boost your search and make it simple to narrow down your options. So, it’s up to you now to find out what your 3D printing tasks need and proceed with the purchase. Good Luck!
