Ask about this product

The TPE Medical filament by Lattice Services is a flexible medical grade filament made of thermoplastic elastomer (TPE) certified for contact with skin (ISO 10993-5). This means that the filament can be used for applications in contact with patient skin and will not cause any irritation.

Furthermore, the TPE Medical filament has an elongation at break of 1600 %, Shore hardness of 88A and excellent resistance to shocks. These features make it ideal for the 3D printing of parts such as flexible surgical models, orthopedic devices and contact parts in interface with rigid parts of orthoses or prostheses.

Another attractive feature of the TPE Medical filament is that parts made with it can be safely sterilized by means of gamma rays or the ETO procedure (Ethylene Oxide Sterilization).

It must be noted that parts 3D printed with the TPE Medical filament can under no circumstance be implanted in humans. The manufacturer does not assume any responsibility for the medical use of the product and each use case must be assessed for its viability for any medical use by the user of the TPE Medical filament.

Once opened, the TPE Medical filament should be stored properly to prevent it from absorbing moisture from the air. The best way to store filaments in a tightly sealed bag with desiccant, in a vacuum sealed container or in an intelligent filament container. During printing, the filament can be placed in PolyBox or the FilaDryer S2 filament dryer.

The manufacturer recommends printing TPE Medical filament at 220-240 ºC on a bed heated to 40-60 ºC. It is recommended to print at a speed of 10-40 mm/s with the layer fan on (50-100 %). It is best to print this material on a 3D printer with a direct drive extruder since it is a flexible material.

It is highly recommended to wear standard safety equipment during the printing and post-processing of parts 3D printed with the TPE Medical filament - safety goggles, gloves, breathing equipment and protective garments, according to needs.
