The advantages of the PET-G Carbon material
When printing with an FDM 3D printer, PLA is by far the most well-known and used printing material, as it is cheap and relatively easy to use in 3D printing. PLA does have disadvantages, for example with heat resistance; however, nowadays there are many different printing materials available, so there is a suitable material for every application.
Freedom of choice in materials
The dddrop 3D printers are specifically designed to give complete freedom when it comes to material choice, 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 housing with temperature control and heated printer bed allow for the creation of models from a multitude of materials. This article takes a closer look at the material PET-G Carbon.
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 makes the filament much firmer and more rigid. Making the filament harder reduces the risk of scratches or other damage when a 3D printed model comes into contact with another object. However, it is more likely to break when dropped compared to regular PET-G filament. PET-G (without the carbon fibers) is best known in the form of PET bottles, which are used to serve soft drinks in. In this form, PET-G looks shiny; however, with the addition of carbon fibers, it becomes matte and anthracite in color.
Easy to print on
The advantage of printing with PET-G Carbon is that the printer settings are largely the same as those of the regular PET-G filament. The working temperature is 80 °C and the material does not warp, so the printed models retain their shape. It is not necessary to have much experience with 3D printing to print perfect models with PET-G Carbon. The disadvantage of printing with abrasive printing materials, such as PET-G Carbon, is increased wear of the brass nozzle. PET-G Carbon is a suitable filament for printing small models. For larger models, you can choose the PA Carbon-filled alternative Novamid® ID 1030 CF10.
DSM’s Novamid® ID 1030 CF10 is a polyamide (PA or while nylon) composition of PA 6/66 combined with carbon fiber. The carbon fiber makes the filament stronger, stiffer, lighter and harder and provides resistance to impact and heat. The combination with the PA filament allows Novamid® ID 1030 CF10 to withstand high temperatures without deforming. As experienced 3D printer operators know, printing PA filament is a bit more challenging because it is a high-tech material. With the right print settings, extensively tested by dddrop and the use of Magigoo PA, for perfect adhesion to the 3D printer bed, this filament is ideally suited for printing larger carbon models. Novamid® ID 1030 CF10 is also a highly abrasive material due to the addition of carbon fiber.
Carbon fiber gives additional strength to the model, while also reducing weight. This makes it well suited for applications where strength and weight are important, such as in drones, the automotive industry and the prosthetic industry.
