Glass Fiber Reinforced Filament

What Is It?

Fibers made of glass reinforced into the polymer during manufacturing and aligned along the axis of filament.

This, along with their physical makeup, give this material enormous strength and mechanical properties.

What Does It Do?

Glass fiber reinforcement gives material a lot of desirable properties:

  • High strength
  • High stiffness
  • High chemical resistance
  • Low thermal expansion

How Does It Work?

Reinforcing plastic with glass fibers produces a 3D printing filament which exhibits the best properties of both fiberglass and the plastic of choice.

What Is It Good For?

Ideal for any applications which require strength and rigidity.

For these reasons, glass fiber reinforced filament is very popular in automotive, mechanical, civil engineering, and research industries.

Abrasive Material

This material is particularly abrasive among 3D printing filaments. Users may find standard brass nozzles are chewed through very quickly compared to standard wear and tear. When worn through, the nozzle diameter will widen inconsistently and the printer will experience extrusion issues.

Because of this, it's strongly recommended this material be printed through a hardened steel nozzle rather than a softer metal. Hardened steel nozzles can often be inexpensive and easily installed depending on your printer manufacturer's instructions.

What is Carbon fiber reinforced Nylons?

Nylons are a family of synthetic polymers composed of polyamides and are the material of choice for many demanding additive manufacturing applications. Nylons tend to be semi-crystalline and are available in different grades (PA6/6, PA6, PA12, etc.) when good mechanical strength, good stability under heat, and/or chemical resistance are required. Chopped carbon fiber may be added to Nylon in order to improve the materials properties, including strength, stiffness, and performance at elevated temperatures.


Carbon fiber reinforced Nylons have become popular for 3D printing professionals wanting to make functional parts.

What can you use Carbon Fiber Reinforced Nylon for?

Carbon fiber reinforced Nylons are great for 3D printing durable, structural parts with high dimensional stability. They can be ideal for a broad range of demanding applications, including:

  • Industrial applications - masking fixtures, conveyor system components
  • Orthotics and Prosthetics - Braces, sockets, inserts
  • Transportation (Automotive, Off-road vehicle, motorbikes) – lever arms, air management components (ducts, tubes)
  • Manufacturing jigs and fixtures
  • Lightweight applications
  • Protective and supporting sports gear and equipment
  • Robotic tooling and end-of-arm tooling


Key benefits and properties of carbon fiber reinforced Nylon filament include:

  • Low warpage compared to unfilled Nylon
  • Durable parts with good mechanical properties and inter-layer strength

Printer Requirements and Settings for Carbon Fiber Reinforced Nylon

In order to prevent moisture absorption, filament should be kept closed in undamaged packaging supplied. Partially used spools should be sealed before storing. Filament should be dried before use, and kept dry during jobs for best results. A heated chamber is recommended to achieve better dimensional and mechanical properties.

JuggerBot 3D’s printers are stand-alone and self-contained, incorporating a material dryer, an independently controlled loading bay, and environmentally controlled build chambers. Learn more by visiting our product page!

3D Printing with Nylon CF- the procedure

Covestro,formerly DSM Additive Manufacturing, provides suggested process guidelines for Novamid® ID1030 CF10, a carbon fiber-reinforced PA6/66 filament. For best results, operators should refer to the following:

  • Drying: Use a desiccant dryer for 4 hours at 80°C / 176°F
  • Extrusion: Extruder temperature should be between 260 - 285°C / 500-545°F.
  • Heated print bed: Heated print bed (>100°C / >212°F), the optimum is 110°C / 230°F. Ensure good bed adhesion at time of print.
  • Build chamber: A heated build chamber reduces the warpage and helps the fusion of the layers during printing. In this way the force is reduced and delamination from the build plate is less likely.
  • Startup/shut down: Production has to start with a clean machine. Starting the machine, extrude at least 50 mm of new filament through the nozzle.

Nylon 3D Printing Technology Features

Nylon is known as a durable, versatile material. It is a synthetic composition formed from polyamides, which are polymers linked by amide bonds. When it comes to 3D printing, Nylon is often considered an "advanced" resource as it requires certain skills and equipment to work with. For printing on a 3D printer, the material is taken in the form of a powder or thread.

Physical properties of nylon

Nylon is a popular choice in industrial 3D printing because of its durability and abrasion resistance. If the surface printed with Nylon is thin enough, it can show good flexibility while maintaining strength.
The compound's low coefficient of friction means it is well suited for making moving parts. Nylon is often used to create functional prototypes, hinges, gears and similar parts.

Chemical Properties of Nylon

To fully understand nylon 3D printing, it is important to consider other characteristics as well. The filament has a high melting point and is hygroscopic, that is, it absorbs moisture well. The latter property can be both an advantage and a disadvantage. The advantage is that the surface of the printed part lends itself well to coloring. Minus - the thread absorbs moisture from the air, which affects the printing process and the characteristics of the finished part.

Choice of technology

3D printing with nylon on a 3D printer has its own peculiarities - it can be realized by the method of layer by layer deposition (FDM) using a nylon filament, by means of selective laser sintering (SLS) or by the method of multi-jet fusion (MJF) using a powder.


Using Nylon for 3D printing was an expensive procedure because MJF and SLS printers are expensive and FDM printers have become a cheap alternative. Today, you can use an FDM printer and a special nylon filament that is melted down and then extruded through a nozzle onto a build platform in layers until the part is complete. Although nylon 3D printing on FDM equipment is much more affordable than SLS or MJF, the quality of the printed object is not as impressive.

Also, not all FDM machines can handle nylon filament. It is important to have a quality (all-metal) hot end that can withstand temperatures above 250°C. Nylon is also prone to warping, so traction becomes a separate issue.
Nylon thread is available in various grades, the most common of which are PA 6 and PA 66. Both options have standard strength, abrasion resistance and low coefficient of friction, but have one significant drawback - high moisture absorption.

Fiber formula of anide (nylon-66) and nylon (nylon-6).


Storage and Nylon Printing

The hygroscopicity of the material may adversely affect the filament. The thread begins to lose its properties, decompose within a few hours. To prevent such a scenario, proper storage is of fundamental importance.

A simple plastic sealed container is a good solution when not using filament, but what about when printing? The ideal output is a moisture controlled storage unit that also feeds the filament to the extruder. If the material on the coil has absorbed a lot of moisture, then it can be dried in a special chamber or oven.


The selective laser sintering method uses a laser to sinter the powder layer by layer. Most of these 3D printers are focused on polymers.
One of the main materials used in this equipment is Nylon, specifically PA 11 and PA 12 nylon powders. There are also powdered versions of reinforced polyamide, known as nylon composites, which, in addition to Nylon, usually contain particles of glass, aluminum or carbon fiber.

When completed, objects are completely surrounded by unspent powder, which serves as a support for printed models. SLS machines can reuse up to 50-70% of the remaining material for future print runs. In terms of rationality, this is an advantage over FDM, since any resource used as supports is usually not converted back into a thread for reuse. Nylon is excellent for making functional parts, and selective laser sintering technology helps create complex configurations.

The downside of this method is the cost. Industrial SLS printers sell for over $200,000. However, more affordable solutions have recently appeared on the market, such as the Fuse 1 desktop SLS machine from Formlabs, priced at about $10,000. You will have to pay at least $60 per kg for the powder.


Multi Jet Fusion is a unique powder sintering technique developed by Hewlett Packard. The technology is similar to the previous one, but also has something in common with the method of jet application of the binder.

MJF and SLS start the Nylon printing process in the same way. Before sintering begins, a layer of powder is spread onto the assembly platform. However, while with SLS the laser would start sintering, MJF introduces an additional step into the printing process in the form of adding chemical agents.

A chemical compound is sprayed on top of each fresh powder layer where future layers will be sintered to help the substance absorb energy from the printer's heat source. When SLS uses a laser, MJF relies on powerful infrared light, which, in combination with the fuser, speeds up the sintering process, making the print go faster.

While both technologies produce phenomenal detail, MJF is ahead of SLS when it comes to detail. This is partly due to the agent used, which helps to make the edges as sharp as possible, slightly reducing the intensity of fusion at the edges of the object.

After printing is completed, the green powder can be disposed of. However, MJF allows up to 80% of the material to be reused, although this largely depends on the specific machines. The MJF technique is comparable in price to industrial SLS machines, but has faster print speeds with potentially better detail.

Nylon for 3D printing with Kevlar, glass and carbon fiber content will allow you to print even body armor




Everyone knows that advances in 3D printing technology are entirely dependent on advances in 3D printing materials. If we talk about industrial production, the choice is huge here: metal, wood, ceramics, etc. But for ordinary people, the situation is rather deplorable, because they only have different types of plastic at their disposal. But a celebration has come on their street too: the worldwide network of 3D printers 3D Hubs, in collaboration with Markforged, has released a new series of nylon materials reinforced with Kevlar, glass and carbon fiber.

Developers of unique advanced materials aim to enable users to create 3D printed products that are as strong as metal and as cheap as plastic. In numbers, fiber-reinforced materials have a higher strength-to-weight ratio than 6061-T6 Aluminum, plus products are 24 times stronger and 27 times more resilient than ABS.

New items will be presented at 17 certified 3D Hubs dealers in Europe, USA and Canada. These materials are ideal for manufacturing factory parts, live prototypes and equipment. True, representatives of 3D Hubs specify that these materials are of little use for the production of small products with fine details.

As mentioned above, 3D Hubs has developed new materials in collaboration with 3D printer manufacturer Markforged, so the new materials are suitable for use on the Mark Two industrial 3D printer and are compatible with the patented Continuous Filament Fabrication (CFF) system. 3D Hubs said in a press release: “Adding fibers in the 3D printing process is a complex procedure and requires the presence of a specially trained operator. Through our network of vendors, we have been able to make this technology more accessible to everyone.”

Of course, the new materials are slightly different from each other. Carbon fiber reinforced nylon has a higher strength to weight ratio than 6061 Aluminum and the highest thermal conductivity of the three. Nylon reinforced with Kevlar has the highest abrasion resistance. In addition, it is the most flexible, so it is a great option for making impact-resistant and durable products. Fiberglass-reinforced nylon is perhaps the most budget-friendly of all, but it still has the same strength as carbon-reinforced nylon. However, it is 60% stiffer and twice as heavy as the latter.

3D Hubs staff has prepared useful tips for those who decide to try their luck with new products. Firstly, these materials are not intended for the production of small and oversaturated objects with details (the minimum part size should be 0.8 mm). The minimum size of the product should not be less than 3 mm, while for products made of pure nylon, the allowable minimum is 1.6 mm.

With regard to the production of movable and interlocking products, make sure that there are gaps of at least 0.5 mm so that the products can be separated from each other at the end of the print session. The wall thickness corresponds to the minimum value of the product, i.e. for reinforced nylon this is at least 3 mm, while for pure nylon it is only 1.6 mm.

Fibre-reinforced nylons require a continuous fiber technology that is based on deposition modeling technology, but requires a second printhead that infuses the nylon with "filaments of carbon, kevlar, and fiberglass between layers. " As the 3D Hubs website says, "These long filaments take all the load, resulting in strong products with properties comparable to those made of composite materials."
