Flexa Grey - 1

Flexa Grey Functional flexibility Flexible prints with increased extensibility | Adjustable hardness | 100% reusable Tensile testing Ultimate tensile strength While the tensile stress does not exceed 1.8 [MPa], after load release, the test specimens retain their shape, with no external damage observed (e.g. fractures). The test specimens fracture when max tensile stress of 3.7 [MPa] is applied. General information Material type TPU Granulation 20 - 105 [μm] Color Grey Material refreshing ratio 1 0 [%] Compression testing Compatible with 2 Lisa & Lisa Pro Tensile Strength 3.7 [MPa] Elongation at Break 136 [%] Shore hardness in type A scale 70 / 90 ³ PN-EN ISO 37:2007 PN-EN ISO 37:2007 PN-EN ISO 868:2005 Melting point 160 [°C] Printout density 0.74 [g/cm³] Printout water absorption 9.1 [%] Thermal properties Softening point (Vicat method 67.6 [°C] type A50) PN-EN ISO 306:2014-02 Internal procedure PN-EN ISO 845:2010 PN-EN ISO 62:2008 While the compressive stress does not exceed 3.5 [MPa], after load release, the test specimens retain their shape, with no external damage observed (e.g. fractures). After applying max compressive stress of 14.65 [MPa] and realeasing the compressive load, the test specimens irreversibly change their volume from: 14.50 [mm] x 14.50 [mm] x 15.30 [mm] to: 14.85 [mm] x 14.85 [mm] x 14.85 [mm]. Applications Easy elastic parts, vibration dampers, general prototyping of elastic parts. Functions Easy to process rubber, adjustable hardness (set up in Sinterit Studio). 1 Material refreshing ratio - percent of Fresh powder which has to be mixed with Used (unsintered) powder - to be reused during next print. FLEXA has 100 [%] of usability. Although to keep the parameters of printouts as high as it is possible, we recommend adding 10% of fresh powder each time. ² Available as part of the appropriate profile purchased. ³ Depending on printing settings. Information provided within this document are average values for reference and comparison only. Parameters presented in this specification are subject to change. Final part properties may vary based on printed part design and print orientation. 20201118_EN
