The PETG Medical filament by Lattice Services is a made from a high quality polyethylene glycol (PETG) base. PETG is an amorphous and rigid thermoplastic that does not crystalize when heated. This gives PETG a wide range of valuable features such as excellent mechanical, thermal and chemical resistance, low deformation, great printability and translucency, making PETG a great alternative to PLA, ABS or PA.

Furthermore, the PETG Medical filament is compliant with the ISO 10993-5 certification for skin contant. In combination with the translucency and chemical resistance, it makes the PETG Medical filament perfect for applications such as prototypes of medical device packaging or prototypes of MD in contact with fluids (respirators, breathing duct, suction, etc).
It must be noted that parts 3D printed with the PETG 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 PETG Medical filament.

Once opened, the PETG 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 PETG Medical filament at 230-245 ºC on a bed heated to 75-85 ºC. It is recommended to print at a speed of 40-70 mm/s with the layer fan on (10-50 %).
It is highly recommended to wear standard safety equipment during the printing and post-processing of parts 3D printed with the PETG Medical filament - safety goggles, gloves, breathing equipment and protective garments, according to needs.
