Windform High-Performing Features


Windform Additive Manufacturing can be used to create internal truss structures. Lightness, strength and stability are the main benefits. This type of structure can be used in several applications. This reticulated structure can be adopted where weight reduction and high stability are required, especially for the industries of aerospace, Unmanned Aerial System, motorsport and automotive.



Windform LX 2.0, Windform XT 2.0, Windform GT and Windform SP have passed outgassing tests that have been carried out at NASA.

The result states: Materials were tested in accordance to the ASTM E-595-07 standard and are considered passing. See the results

CNC Machine 3D-Printed Parts

Windform 3D-printed parts can be CNC machined leading to:.

High Dimensional Accuracy - There are industries such as motorsport, automotive, medical, aerospace and UAS that require tight specifications. With CNC machining it is possible to bring tolerance down to hundredths of millimeter.
Windform parts can be CNC machined with 5-axis milling centers and with lathes in order to have complex and highly accurate features.

Speed up the production and Save time – The combination of 3D printing and high precision CNC machining leads to speed up the manufacturing process of the parts and save time. The additive manufacturing technology is much faster than designing and producing a tool for injection molding. Furthermore, 3D printing can give engineers more flexibility in the timeline to make design improvements.
They have only to update the file CAD/CAM and print a new part, while making changes to an injection molding tool is nearly impossible and expensive causing a delay in the production of the parts. Furthermore the technology of 3D Printing allows free-form design and complex features.

Windform SP and Windform GT are waterproof. They have excellent sealing characteristics both to liquids (water, oil, gasoline, etc...) and gas.

Waterproof 3D printing material


Windform GT and Windform LX 2.0 have passed both the patch epicutaneous test and the analysis performed on the leaching liquid. The results show that Windform GT and Windform LX 2.0 can be used to create devices which can be applied on skin. The tests are to assess and gauge the compatibility with the human skin as absence of skin irritation.

Thanks to the mechanical features of Windform materials, it is possible to create 3D-printed breathable prototypes and parts.

breathable 3D printing material


Windform LX 2.0, Windform LX 3.0 and Windform GT are non-conductive materials so they are suitable for electronic applications, such as electronic control units components, electrical connectors and any prototypes in touch with electronic items.
Windform 3D-printed Shunt Support sustains the electrical components insulating them. The DC is 300 Volt.
The Shunt Support is located inside the battery of the electric motorcycle Energica Ego.

non conductive 3D printing material

Windform Additive Manufacturing is particularly appreciated in space for their mechanical specifications.
The stator and the retaining rings have been built in Windform LX 2.0 and Windform XT 2.0 for a space customer. These two rings have been launched into orbit as part of a Reaction Wheel.
These parts are still in orbit.

Flammability UL 94 HB test

Windform XT 2.0, Windform SP, Windform GT and Windform LX 3.0 have been tested for their flammability rating. They have been rated HB according to the flammability UL 94 test.
The “Test for flammability of plastic materials for parts in devices and appliances” UL 94 was carried out on test specimens 1 to 3 mm thickness.
The result of the flammability UL 94 HB test reports Windform® XT 2.0, Windform® SP, Windform® GT and Windform® LX 3.0 have successfully obtained the HB classification.
