SMARTFIL FLEX FOAM is a flexible and expandable TPU filament specially designed to create 3D prints that are lightweight, durable, and highly elastic. Its unique property allows you to control filament expansion through temperature and extrusion flow, achieving a perfect “foam” effect for cushioning components, anti-vibration parts, and lightweight elements. This combination of flexibility, durability, and dimensional accuracy makes it an ideal choice for functional prototypes, drones, robotics, technical footwear, and automotive components.

3D Printing Optimization: Temperature and Flow

The performance of expandable flexible TPU filament depends on maintaining the right balance between temperature and extrusion flow. Adjusting these settings ensures precise, consistent, and lightweight prints, prevents over-extrusion, and guarantees dimensional stability in every print.

Printing within the range of 220–250 °C and setting the flow between 40–60 % allows the filament to expand in a controlled way, resulting in uniform, durable, flexible, and lightweight parts, perfect for technical applications and high-demand prototypes.

For lightweight, durable 3D parts with controlled “foam” effect, it is recommended:

Printing temperature: 220–250 °C depending on desired density.
Printing speed: 20–30 mm/s for uniform extrusion and precision.
Bed temperature: 0–50 °C to improve adhesion and reduce warping.
Fan: 60–80 % for controlled cooling and even finish.
Material flow: 30–100 % adjusting according to expansion and density.
Enclosed chamber: not required, but helps with large parts.

Tip: correctly combining temperature and flow allows control of density, elasticity, and dimensional accuracy, achieving professional results in any 3D project.
