Voronoi Mesh in TPU: the 3D textile that breathes for you this summer

Published on June 02, 2026 | Translated from Spanish

This week, The 3D Summer Seamstress launches a printed textile designed for extreme heat days. It is a Voronoi geometry mesh designed for flexible filaments like TPU 95A. With a thickness of 1.2 mm and irregular cells that generate micro-ventilation channels, these panels promise to maintain constant airflow in the most critical areas of the body. The pieces are joined with PLA rings or sewn to recycled cotton, offering a breathable and functional alternative.

Technical data for printing your own ventilation system 🛠️

The panels are recommended in a size of 150 x 150 mm, scalable as needed. The layer height is 0.2 mm, with 0% infill (the Voronoi geometry provides the structure) and 2 perimeters for soft-to-the-touch edges. The estimated print time is 2h 15min per panel on a standard printer. The design is support-free if oriented in the XY plane; it only requires a wash with soapy water. It is washable up to 40 °C and is advised to be combined with recycled polyester for greater durability.

Goodbye sticky armpit, hello algorithmic geometry 😎

Finally, science fiction reaches the armpits. This mesh not only prevents the fabric from sticking to sweaty skin but also turns your back into a high-performance radiator. Of course, be careful when sitting down: the Voronoi pattern can leave marks on the shirt that look like a map of secondary roads. But hey, that's better than looking like a sweaty seal at the beach. Ideal for pairing with wide-brimmed hats and open sleeves printed in the same material.
