Collection: Nylon Filaments

PA is a material that is sensitive to temperature fluctuations and shrinkage, which is why it clearly benefits from a heated printing chamber. Regular PA often requires even significantly higher chamber temperatures than carbon fiber-reinforced PA CF, as the lack of fibers makes the material more flexible and more susceptible to deformation during printing. When the chamber temperature is not high enough or the environment is drafty, parts can curl, shrink and lose their dimensional stability even in medium-sized prints. A warm, even temperature environment is therefore one of the most important factors for successful PA printing.

PA-CF is an exception to this, as the carbon fibers stiffen the material and reduce its tendency to shrink or warp during printing. This makes PA-CF a slightly more manageable option for larger parts, as the fiber reinforcement stabilizes the geometry and reduces the need for a particularly hot chamber environment. While a closed chamber is still highly recommended, PA-CF is more tolerant of slight temperature fluctuations and therefore offers a more consistent end result when the goal is a large-scale or structurally demanding print.

However, the basic properties of nylon are the same in both options: the material is highly wear-resistant and performs excellently in applications requiring mechanical stress. It is suitable for applications such as gears, hinges, load-bearing fasteners and sliding surfaces, where layer fusion and internal strength of the material are essential. PA absorbs moisture quickly, so careful drying before printing is important to ensure a high-quality surface and layer adhesion.

Printing PA is not the easiest for a beginner, but it rewards its users with parts that can withstand use in a way that many other materials cannot. PA CF also offers dimensional stability and rigidity for demanding applications without having to print in a very hot chamber every time. Both options are great for users looking for industrial features in their home printers and want their prints to withstand real-world stress.
