The advantages of the material PET-G Carbon
When printing with an FDM 3D-printer, PLA is by far the most well-known and commonly used printing material, because it is inexpensive and relatively simply to use in 3D printing. PLA does have its drawbacks, for example with heat resistance; however, nowadays there are many different printing materials available, offering a suitable material for every application.
Freedom of choice in materials
The dddrop 3D printers were specially developed to give a complete freedom when it comes to choosing materials thanks to the dddrop open filament policy. This means that users are not only free to choose any filament supplier, but also any material. The closed casing with temperature control and heated printer bed allow to create models from a multitude of materials. This article will discuss the material PET-G Carbon in more depth.
Carbon means carbon fiber-reinforced polymer. In carbon filled filament, small fibers are added to the base material, in this case PET-G, to enhance the qualities of the base material. Carbon fiber is a remarkably strong material and make the filament much more sturdy and stiff. Making the filament harder reduces the risk of scratching or other damage when a 3D printed model comes into contact with another object. However, it is more likely to break when dropped than regular PET-G filament. PET-G (without the carbon fibers) is best known in the shape of PET-bottles, used to serve sodas. In this form the PET-G looks shiny; however, with carbon fiber added it becomes matte and anthracite colored.
Easy to print
The plus-side of 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 does not warp, so the printed models will retain their shape. It is not necessary to highly experienced in 3D printing 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 dddrop shop and at our trusted resellers. PET-G Carbon is a suitable filament for printing small models. For larger models, opt for the PA carbon-filled alternative Novamid® ID 1030 CF10.
Novamid® ID 1030 CF10 from DSM is a polyamide (PA or while nylon) composition of PA 6/66 in combination with carbon fiber. The carbon fiber ensure that the filament becomes stronger, stiffer, lighter and harder and offers resistance to collision and heat. Due to the combination with the PA filament, Novamid® ID 1030 CF10 can withstand high temperatures without distorting. As the experienced 3D printer operators know, printing PA filament is a bit more challenging because it is a high-tech material. With the correct print settings, extensively tested by dddrop and the use of Magigoo PA, for perfect adhesion to the 3D printer bed, this filament is extremely suitable for printing larger carbon models. Novamid® ID 1030 CF10 is also a very abrasive material due to the addition of carbon fiber; however, the tungsten carbide nozzle works perfectly as an alternative to the standard nozzle that is more susceptible to wear down. The tungsten carbide nozzle has a considerably longer service life than the standard brass nozzles.
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, the automotive, and prosthetic industries.
