The matte finish of MattFlex 40D adds a visually appealing, low-gloss look to printed parts (unlike FiberFlex 40D), minimizing the visibility of layer lines and enhancing surface quality. This feature makes it an excellent choice for applications where aesthetics are important, such as prototypes, gadgets, or display items. Additionally, the filament requires minimal post-processing, as the matte surface effectively hides imperfections and creates a smooth, professional finish.

In addition to its aesthetic appeal, MattFlex 40D offers notable functional benefits, making it ideal for various applications in both household and industrial settings. Its impressive resistance to impact, tension, and compression—with up to six times the tensile strength and 50% more compressive resistance—makes it a versatile material for creating flexible parts, such as machinery gaskets, phone cases, watch straps, and even hinges. Moreover, its resistance to chemicals, abrasion, and low temperatures broadens its range of applications, making it suitable for demanding environments and uses like durable toys, flexible seals, and wearable accessories.
