What is 3D Printer Filament?

Okay, before we get to the good stuff, let's make sure we're all on the same page. What is 3D printer filament, anyway? Simply put, it's the raw material that your 3D printer uses to build your models. Think of it like the ink for your printer, but instead of ink, you've got a long strand of plastic that gets melted and layered to create your 3D objects. Filament comes in various materials, each with unique properties and best uses. The most common form factor is a spool of filament, usually around 1kg, which feeds into your printer. The diameter of the filament is also standardized, with 1.75mm and 2.85mm being the most common sizes, so make sure to check what your printer uses before you buy anything. Selecting the right type of filament is the first step toward successful 3D printing. It affects everything from how easy it is to print to the strength and appearance of your finished product. Some filaments are beginner-friendly because they are easy to print and don't require fancy printer settings. Others are more advanced and might need a heated bed or enclosure to print correctly. The material you choose will depend on what you want to create. This is something that you'll have to consider when looking for the best beginner 3D printer filaments. For example, if you're making a simple decorative item, you might choose a filament that's easy to print and comes in cool colors. If you're creating something functional, like a replacement part, you'll need a filament that's strong and durable. Remember, a good understanding of filaments is key to unlocking the full potential of your 3D printer!

Top Filament Choices for Beginners

Alright, let's get into the best beginner 3D printer filaments! Here are some of the top choices for those just starting out, along with their pros and cons:

PLA (Polylactic Acid)

PLA is often the go-to choice for beginners, and for good reason. It's made from renewable resources like cornstarch or sugarcane, making it more environmentally friendly than some other plastics. PLA is super easy to print with, typically requiring lower temperatures and often doesn't need a heated bed. This makes it perfect for those with basic 3D printers. The lower printing temperature means it warps less, and there's a reduced risk of your print lifting off the build plate. PLA comes in tons of colors and is generally quite affordable. However, PLA isn't without its downsides. It's not the strongest material, and it can become brittle over time or in high-temperature environments. This means it might not be ideal for parts that need to withstand a lot of stress or be used outdoors. It's also sensitive to moisture, so you'll want to store your PLA filament in a dry place to prevent it from absorbing water, which can affect print quality. Despite these minor drawbacks, PLA's ease of use and eco-friendliness make it a fantastic starting point. You can print all sorts of things with it, from decorative items and prototypes to toys and models. If you're just getting started, PLA is definitely a great place to begin.

PETG (Polyethylene Terephthalate Glycol-modified)

PETG is another popular choice, and it's a step up from PLA in terms of durability and temperature resistance. It's a fantastic middle ground because it's still relatively easy to print, especially compared to some other more advanced filaments. PETG offers a good balance of strength, flexibility, and clarity, making it suitable for a wide range of applications. It's more durable than PLA, so it can handle more wear and tear, and it has better temperature resistance. This means your prints are less likely to deform in warmer conditions. PETG is also less prone to warping than some other materials. Although it's slightly more difficult to print than PLA, you usually don’t need a lot of adjustments to your printer settings. You typically need a heated bed, but that's pretty standard for most modern 3D printers. It doesn't have the same environmental benefits as PLA since it's derived from petroleum, but it is often recyclable, which is a plus. PETG is an excellent option for functional parts, like brackets, clips, and containers. You can even use it for some outdoor applications, as it handles UV exposure a bit better than PLA. Overall, PETG is a versatile filament that provides a good combination of strength and ease of use, making it a worthy choice for beginners. For someone looking to move beyond simple decorative prints but not ready to dive into more complex materials like ABS, PETG is an excellent next step.

ABS (Acrylonitrile Butadiene Styrene)

ABS is a well-known plastic used in many everyday products, from LEGO bricks to car parts. It's strong, durable, and can withstand higher temperatures than PLA or PETG. This makes it suitable for items that need to be heat-resistant or endure physical stress. ABS is a bit more challenging to print than PLA or PETG. It requires a higher printing temperature and a heated bed, and it's prone to warping. You might also want to consider using an enclosure for your 3D printer to maintain a consistent temperature and prevent warping. Printing with ABS can also release fumes, so good ventilation is essential, and printing in a well-ventilated area is a must. One of the main benefits of ABS is its strength and resistance to impact. It's ideal for functional parts that need to be tough and durable. ABS is also great for post-processing; you can sand it, paint it, and glue it easily. Despite the extra effort required to print it, ABS is a valuable filament for creating robust, long-lasting parts. While it's not the first choice for absolute beginners due to its more complex printing requirements, understanding ABS is crucial for anyone who wants to explore advanced 3D printing applications.

How to Choose the Right Filament

Okay, we've gone through some of the best beginner 3D printer filaments, but how do you actually choose which one to use? Here are a few things to consider:

Project Requirements

Think about what you're making. Is it a decorative item, a functional part, or something in between? If it's a decorative item, PLA is probably your best bet because it's easy to print and comes in a huge range of colors. If it needs to be strong or heat-resistant, PETG or ABS might be more suitable. Consider the environment your print will be used in. Will it be exposed to sunlight, moisture, or high temperatures? This will help you narrow down your choices.

Printer Capabilities

What kind of 3D printer do you have? Does it have a heated bed? Does it have an enclosure? Some filaments, like ABS, require a heated bed and an enclosure to print correctly. PLA and PETG are usually more forgiving and can be printed on most printers. Check your printer's specifications to see which filaments it supports and what the recommended print settings are.
