Forward AM recommends it for \u003cstrong\u003eenclosures and functional prototyping\u003c\/strong\u003e, as well as consumer products with skin contact such as \u003cstrong\u003ewearables\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eThe Best of Both Worlds: Rigid and Flexible\u003c\/h3\u003e\n\u003cp\u003eRigid resins are strong but brittle, while flexible resins absorb impacts but struggle to hold their shape. The ST 1400 combines the strengths of both: its \u003cstrong\u003e1,900 MPa modulus\u003c\/strong\u003e keeps parts dimensionally stable, while \u003cstrong\u003e43% elongation at break\u003c\/strong\u003e means they deform significantly before failing. On top of that, its \u003cstrong\u003ewater absorption of just 0.33%\u003c\/strong\u003e helps parts retain their mechanical properties over time.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cp\u003eData sourced from the official Forward AM (BASF) datasheet and product catalog.\u003c\/p\u003e\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eProperty\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003cth\u003eStandard\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eYoung's Modulus\u003c\/td\u003e\n\u003ctd\u003e1,900 MPa\u003c\/td\u003e\n\u003ctd\u003eASTM D638\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTensile Strength\u003c\/td\u003e\n\u003ctd\u003e45 MPa\u003c\/td\u003e\n\u003ctd\u003eASTM D638\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eElongation at Break\u003c\/td\u003e\n\u003ctd\u003e43%\u003c\/td\u003e\n\u003ctd\u003eASTM D638\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFlexural Modulus\u003c\/td\u003e\n\u003ctd\u003e1,540 MPa\u003c\/td\u003e\n\u003ctd\u003eASTM D790\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFlexural Strength\u003c\/td\u003e\n\u003ctd\u003e80 MPa\u003c\/td\u003e\n\u003ctd\u003eASTM D790\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNotched Izod Impact\u003c\/td\u003e\n\u003ctd\u003e43 J\/m\u003c\/td\u003e\n\u003ctd\u003eASTM D256\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHardness\u003c\/td\u003e\n\u003ctd\u003e78 Shore D\u003c\/td\u003e\n\u003ctd\u003eASTM D2240\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHDT at 0.45 MPa \/ 1.8 MPa\u003c\/td\u003e\n\u003ctd\u003e57 °C \/ 48.7 °C\u003c\/td\u003e\n\u003ctd\u003eASTM D648\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWater Absorption\u003c\/td\u003e\n\u003ctd\u003e0.33%\u003c\/td\u003e\n\u003ctd\u003eASTM D570\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSkin Contact\u003c\/td\u003e\n\u003ctd\u003eISO 10993-10\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUV Stability\u003c\/td\u003e\n\u003ctd\u003eISO 4892-2A\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTechnology \/ Color\u003c\/td\u003e\n\u003ctd\u003eLCD (incl.
