3D printing is revolutionizing the way people create and manufacture products. It offers users a wide range of design options, allowing them to produce objects with complex shapes and intricate detail.
But what type of filament should you use for your 3D printing project?
Different filaments have different properties and strengths. To build sturdy and durable objects to meet certain industry standards, it’s important to select filaments with high “Strength Standards”, consisting of: tensile strength, impact resistance, UV resistance, chemical resistance and temperature resistance.
These qualities factor into determining the strength of 3D objects, so it’s important to put into consideration various parameters when choosing the right filament for your project.
What is The Strongest Filament in 3D Printing?
PEEK is currently recognized as the strongest and most popular 3D printing filament. It’s affordable, durable, and well easy to use. It produces strong parts that are resistant to heat, shock, and chemicals.
While all filaments have their unique properties, PEEK filament is arguably the strongest filament available for the 3D printing industry. It has an incredibly high tensile strength and is lightweight, making it perfect for 3D printing applications that require a strong yet lightweight part.
PEEK filament offers a viable option for producing functional, high-performance parts using 3D printing technology, especially in industries that require materials with exceptional properties and performance in demanding environments.
What Are The Different Types of 3d Printing Filament?
3D printing filament is the material used in 3D printing to create an object. Depending on the type of filament you use, your prints can have different properties like strength, thermal resistance, abrasion resistance, flexibility, durability, and more.
There are several types of 3D printer filaments available in the market today for you to choose from depending on what you need for your project. These are the most commonly used ones:
PEEK Filament
PolyetherEtherKetone (PEEK) filament is a high-performance thermoplastic that is known for its strength, toughness, and heat resistance. It is often used in applications where these properties are essential, such as the aerospace, medical, and automotive industries. PEEK filament is available in a variety of colors and diameters and can be printed on a variety of 3D printers.
ABS Filament
Acrylonitrile Butadiene Styrene (ABS) is one of the most popular 3D printing filaments as it’s affordable, durable, and easy to use. It produces strong parts that are resistant to heat, shock, and chemicals. ABS filament is usually available in a wide range of colors and can be printed faster than other filament types.
PLA Filament
Polylactic Acid (PLA) is the most popular 3D printer filament due to its ease of use, affordability, and availability. It’s made from cornstarch or sugarcane so it’s also biodegradable. PLA produces strong prints with good layer adhesion but is not as durable or heat-resistant as ABS.
PETG Filament
Polyethylene terephthalate glycol (PETG) is a 3D printing filament that combines the best of both ABS and PLA filaments for superior strength and excellent durability. It is stronger than PLA and more heat-resistant than ABS, making it a great choice for functional parts and everyday use.
Nylon Filament
Nylon filament is one of the strongest 3D printer filaments available due to its flexible material and high tensile strength. It has excellent chemical resistance, dimensional stability, and high-temperature resistance making it ideal for functional parts and end-use products.
Wood Filament
Wood filament is becoming increasingly popular among 3D printer users due to its unique look and feel. This filament is made from a combination of recycled wood particles, binding agents, and plastic polymers. It produces prints that are lightweight yet strong with a wooden texture that can be sanded and painted.
Carbon Fiber
Carbon fiber is widely recognized filament for 3D printing. It has an incredibly high tensile strength and is incredibly lightweight, making it ideal for applications that require a strong yet lightweight part. As you might expect, carbon fiber filaments can be very expensive and require specialized hardware to print with.
Polycarbonate Filaments
Polycarbonate is a popular choice for 3D printing due to its versatility, filament strength, and durability. It is the most heat-resistant filament available and can be used in a variety of temperatures and environments. Polycarbonate has excellent mechanical properties, making it ideal for parts that require high-impact resistance or will be exposed to high-temperature applications.
These are just some of the popular 3D printing filaments available today. With so many options available, you’re sure to find the right filament for your project.

What Factors Influence The Strength of a Filament?
The strength of a filament is determined by multiple factors. Some of these include the type of material used, its diameter, and temperature.
Material
Different types of materials will react differently to mechanical stress, so it’s important to use a filament that is suited for the job at hand. Polylactic Acid (PLA) is a popular choice for 3D printing, as it is affordable and easy to work with.
It also has good layer adhesion and can be used to create detailed objects with complex geometries. On the other hand, Nylon (PA) offers greater strength, flexibility, and higher temperature resistance than PLA.
Diameter
Filament diameter affects the strength of a filament, with thicker filaments being stronger than thin ones. For both PLA and PA, 2.85 mm is the most commonly used diameter for 3D printing, as it offers a good balance between structural integrity and detail resolution.
Temperature
Filament temperature can affect its strength in two ways: too low and the filament won’t be able to adhere properly, while too high and the filament can become brittle. For PLA, the optimal printing temperature is usually between 195 – 220°C. As for PA, its range is narrower at 205-220°C
Ultimately, understanding these factors will help you select the best type of filament for your 3D printing project. With the right 3D print filament, you can create high-quality objects that are both strong and detailed. So keep these things in mind before beginning your next 3D printing project!
How do you Select The Strongest Filament for Your Application?
When it comes to selecting the strongest filament for your application, it’s all about understanding what strength is needed and then finding a suitable material that meets those requirements.
Start by evaluating the mechanical properties of the part you’re printing and determine which areas require extra strength. Are there any elements in your design that need to be rigid or flexible? Does your print have to withstand harsh environments and conditions? Once you have a clear picture of the strength you need, you can begin to explore a wide selection of filament materials and their properties.
For example, if you need a strong material for your application, then look for a filament with high tensile strength (the amount of force required to break it) or one that offers excellent impact and fatigue resistance. Some filaments are specifically designed to be strong, so it can help to do some research into these.
Additionally, keep in mind the characteristics of different plastics as they can vary significantly. PLA and PEEK both offer excellent strength but can have different properties when it comes to flexibility, temperature resistance, or chemical resistance.
Finally, if you’re looking for a filament that can stand up to a hostile environment, look for one that is reinforced with added strength. For example, if you’re printing something like a tool handle or automotive components, then consider using reinforced filaments such as carbon fiber or Kevlar. These materials have high structural strength and can provide extra rigidity and durability that traditional plastic filaments cannot match.
