Smart Print FLEX filament is a high-quality flexible material designed for FDM/FFF 3D printing, ideal for applications where flexibility, elasticity, and long-term durability are needed. FLEX (a TPU/TPE-type filament) is used to print parts that must absorb impacts, bend without damage, and return to their original shape after deformation. Thanks to its balanced properties, it is suitable for both hobby and professional projects.

The key advantage of FLEX filament is its high flexibility and toughness. Smart Print FLEX allows you to print parts that bend without cracking and retain their properties even under repeated stress. The material is also resistant to abrasion, vibrations, and mechanical impacts, making it an ideal choice for practical functional applications.
Smart Print FLEX filament is ideal for printing seals, caps, protective covers, feet, grommets, straps, bushings and other flexible parts. It is also useful for mounts with a damping function, components exposed to vibrations, or wherever a combination of flexibility and mechanical resistance is required. Thanks to good layer adhesion, prints are strong and reliable even during long-term use.
For best results, it is recommended to print FLEX filament at a lower speed and with stable material guidance. Using a direct drive extruder is ideal, as it makes feeding flexible filament easier; however, with proper settings it can also be printed on Bowden systems. Good bed adhesion and careful retraction settings are also important to ensure a smooth, trouble-free print.
If you are looking for a material for flexible 3D printing that combines flexibility, strength, and reliability, Smart Print FLEX filament is an excellent choice. It fits a wide range of applications—from simple protective elements to functional parts exposed to mechanical stress.
