Sinterit has introduced a new powder for desktop SLS 3D printers —a flexible TPE material that combines the advantages of both plastics and rubber. TPE is elastic, with an elongation at break of 196%, several times higher than the tested values for PA series materials. Furthermore, TPE can be impregnated with a sealant to give the SLS 3D printed product waterproof and airtight properties—offering additional new functionality.
TPE shares similar properties with rubber, including reusability and elastic deformation. However, TPE materials can be used in 3D printing , making them ideal for prototypes such as footwear and hoses. More importantly, because TPE is an environmentally friendly, non-toxic material without allergens or irritants, it is suitable for contact with the human body, such as in wristbands, handles, and wearable devices. TPE is also commonly found in households, widely used in toothbrush or razor handles, furniture handles, and in flexible casings such as mobile phone cases, motorized grips, and push-button switches—all integrated into our daily lives.
"Introducing TPE materials into Sinterit 3D printers is crucial because it opens up possibilities for our customers," emphasizes Sinterit co-founder Konrad Głowacki. "The earlier availability of TPU powder materials gave customers more options for prototyping; water impermeability and airtightness are the next key requirements." These specific needs make TPE materials ideal for automotive, industrial, and general parts applications.
Because SLS 3D printed objects use laser sintering to fuse molecules together, this process creates numerous tiny pores. Therefore, original SLS 3D printed objects are not completely airtight or waterproof. However, using this 3D printed object with Sealer for TPE sealant can achieve this specific requirement while still maintaining its elasticity.
Whether you're a Sinterit Lisa or the latest Lisa Pro user, you can use this TPE powder for 3D printing to create soft, flexible parts. Due to TPE's high resilience, any component requiring impact or vibration resistance (such as shock absorbers) can be 3D printed and directly tested using TPE . Furthermore, its anti-slip properties are ideal for the automotive industry, making soft, non-slip components such as anti-slip mats, cup holders, carpets, door and window seals, or adjustment knobs.
