The advantages of the material PET-G Carbon
When printing with an FDM 3D-printer, PLA is by far the most well-known and used printing material. It is relatively cheap and not overly complicated to use in 3D printing. Even so, PLA does have its drawbacks, for example with heat resistance. Luckily, nowadays there are many different printing materials available, offering a suitable material for every application.
Freedom of choice in materials
The dddrop 3D printers with their open filament policy were specially developed to give you complete freedom when it comes to choosing your material. This means that you are not only free to choose any producer, but also any material. The closed casing with temperature control and heated printer bed allow you to create models from a multitude of materials. In this article we’ll discuss the material PET-G Carbon in more detail.
Carbon means carbon fiber-reinforced polymer. With carbon filled filament small fibers are added to the base material, in this case PET-G, to enhance the qualities of said material. Carbon fibers are remarkably strong and make the filament both stronger and more stiff. It is harder, which reduces the risk of scratching or other damage when the model comes into contact with another object. However, it is more likely to break when dropped than regular PET-G filament. The material PET-G (without the carbon fibers) is best known in the shape of PET-bottles, used to serve sodas. In this appearance the PET-G has a shiny look to it. With the carbon fibers added, however, it becomes matte and anthracite colored.
Easy to print
The plus-side to printing with PET-G Carbon is that the printer settings are mostly the same as for regular PET-G filament. The working temperature is 80 °C and the material doesn’t warp, so the printed models will retain their shape. It’s not necessary to be a seasoned 3D printer to print perfect models with PET-G Carbon. The downside to printing with abrasive printing materials such as PET-G Carbon, is increased wear to the brass nozzle. A solution to this is a tungsten carbide nozzle, which will be available in the near future.
Carbon fibers give extra strength to the model, while also reducing weight. This makes it very suitable for applications where strength and weight are of importance, such as in drones or the automotive or prosthetic industries.
Another new dddrop filament, PA Carbon, will also be brought to market soon. This new material combines the wear resistance and high working temperature of PA with the strength of carbon.
