Best Durable 3D Printer Filament

If you require a long-lasting, high-performance item that can resist heavy impacts and repeated use, you'll want to print with the best materials available. What kind of filament should you use yet? Numerous materials are available, but each has unique properties and is best suited for specific applications. 

In this article, we'll go over the most robust filaments for 3D printing that may be at the highest level on your list. To better understand their structural durability, we'll examine the tensile strength of 3D printer materials or how much stress a material can bear before cracking when stretched. We can also talk about elongation at break, which shows how far a filament can stretch before breaking and provides information on impact resistance.

What is the Toughest 3D Printer Filament?

Out of all the printing materials now available, polycarbonate filament is the strongest. It is used to make bullet-proof glass, riot gear, phone and computer cases, scuba masks, and many other things. PC's durability and rigidity greatly outweigh those of other printing materials. Polycarbonate filament has a substantially greater glass transition temperature rate than most other plastic filaments, indicating that it has a strong temperature tolerance.

ABS filament is another strong material, but you'll be surprised to learn that Polycarbonate filament can endure 40°C greater than ABS, making it incredibly sturdy. It's possible to bend thin PC prints without cracking or twisting, even at room temperature. It is less susceptible to wear and tear than other materials, which is advantageous for numerous 3D printing applications.

PC has incredible impact strength, which is greater than that of glass and several times that of acrylic materials. Aside from its amazing power, PC is also translucent and lightweight, making it a viable candidate for 3D printing materials. The tensile strength of the Polycarbonate filament is 9,800 PSI, and it can lift up to 685 pounds.

The extruding temperature of polycarbonate filament, which varies depending on the various types of 3D printers and their components, is almost 260°C, and a heated bed of about 110°C is necessary for successful printing.

Top 5 Strongest 3D Printer Filaments

1. Polycarbonate (PC)

Polycarbonate filament

Polycarbonate is a strong filament that has high impact strength, transparent and lightweight qualities, temperature resistance, and toughness. The polycarbonate filament is one of the most potent 3D printer filaments on the market right now, according to a study published in 2020 that discovered it has a tensile strength of more than 5200 PSI.

In addition, UV radiation and chemicals don't affect polycarbonate filament too much. As an additive, it may even be heated to 140°C prior to softening and considerably enhances the characteristics of ABS filament. Due to these qualities, they are suitable for printing practical prototypes, protective gear, and medical devices.

The disadvantages of PC filament are also quite obvious. Due to its warping ability and complex printing properties, it can be difficult to print at times and tends to absorb moisture. You will need an enclosed 3D printing machine and a proper filament storage box to ensure the smooth printing of the finicky PC filament.

The strongest filament for 3D printers for applications requiring durability and high temperatures will be polycarbonate after overcoming these difficulties.

2. Nylon

Nylon filament

Nylon is an additional strong filament that is both tensile and impact-resistant. Nylon filament requires an extruder temperature of about 250 °C and a heated bed set to about 80 °C, making it slightly easier to print even if it is not as durable as PC.

Nylon is undoubtedly more commonly connected with selective laser sintering (SLS), in which powder form is utilized to manufacture industrial parts and prototypes. The price of nylon FDM 3D printer filament is normally lower than that of PC, yet it is still readily accessible. It is significantly more flexible than PC, which may be desired for certain functional elements. Other benefits of nylon filament are its high resilience, smooth surface, and layer adherence.

Although nylon filament can be processed by the majority of desktop printers, the high-strength material has limitations. For instance, it absorbs moisture quickly and is highly hygroscopic, which can result in a number of printing problems, such as the development of bubbles in the nozzle. Nylon, like PC, is vulnerable to warping as it cools.

Ultimaker Nylon, MatterHackers Pro Series Nylon, and ColorFabb PA are some of the popular nylon filaments.

3. ABS

ABS Filament

One of the first 3D printing thermoplastics was the Acrylonitrile Butadiene Styrene (ABS) filament. It is still a widely used material due to its versatility and low cost. However, PETG and ASA filament are preferred over ABS due to their superior qualities.

According to a 2019 study, the ultimate tensile strength of ABS is over 4500 PSI. Even though ABS has a lesser tensile strength than polycarbonate filament due to this, it may still be preferable because of its accessibility and relative simplicity of printing.

ABS can be used to make working prototypes, packaging, and automobile parts. Because of its high melting temperature, it is more heat resistant than other 3D printing filaments. This is critical in applications where the product must survive greater temperatures, such as in an automobile exposed to direct sunshine.

Acetone can be used to post-process ABS 3D-printed items. It will give your items a smooth, shiny surface finish. ABS filament is thus suited for printing beautiful objects and people. However, ABS filament is susceptible to warping, just like other high-temperature thermoplastics. Although it is possible to print it on most low-cost 3D printers, it is preferable to 3D print ABS filament inside a 3D printer enclosure. This also aids with the containment of 3D printing fumes, which is a common issue with ABS filaments.

4. PEEK

PEEK filament

In the vast 3D printing market, PEEK filament is one of the most dependable and trusted materials. PEEK is an acronym for Polyether Ether Ketone, which is a semi-crystalline thermoplastic.

It is widely recognized for its exceptional strength and chemical resistance. At a very high temperature, a procedure called phased polymerization is used to manufacture it. This technique renders the filament very resistant to bio, organic, and chemical degradation in any environment, with a suitable operating temperature of 250°C.

PEEK filaments for 3D printers are gaining popularity in the medical disciplines and other industries because they prevent moisture absorption and simplify the sterilization process.

5. TPU



 

TPU Filament

TPU filaments are generally flexible, but they have a high level of strength in terms of chemical and abrasion resistance, impact resistance, and wear and tear resistance. They are also highly durable and have excellent shock-absorbing properties.

The flexibility of a Thermoplastic Polyurethane filament is determined by the materials used to make it. This varies from manufacturer to manufacturer, with some offering both high elasticity and incredible stiffness. Most TPU filaments can withstand extremely high weights and stresses before breaking. Because of its excellent wear and tear resistance, superior abrasion qualities, and high chemical resistance, It is ideal for printing protective gear, phone cases, prostheses, and even footwear.

TPU filaments have the advantage of not requiring high-end 3D printers and may be used at low temperatures. However, their flexibility makes printing 3D models using Bowden extruders difficult. If you want to prevent jamming the hot end, you'll need to 3D print at very moderate speeds. You also need to keep in mind that, when using TPU components, setting greater infill values will make 3D parts stiffer and vice versa.
