Its transparent formulation offers a tensile modulus of 1500 MPa and a flexural modulus of 1700 MPa, with a Shore D hardness of 80.\u003cbr\u003e\u003cbr\u003eThe viscosity decreases from 400 mPa·s at 30 °C to 120 mPa·s at 50 °C, facilitating handling in the vat. The liquid resin density is 1.08 g\/cm³, and the cured part density reaches 1.12 g\/cm³.\u003c\/p\u003e\n\u003ch2\u003eMechanical Behavior\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eST 80 resin maintains ductile behavior with an elongation at break of 20% and a tensile strength of 35 MPa, complemented by a flexural strength of 60 MPa. Izod impact tests yield 24 J\/m on notched specimens at 23 °C and 720 J\/m on unnotched specimens, while notched Charpy impact results in 1.4 kJ\/m². Cold weather performance is documented with a notched Izod of 14 J\/m at -30 °C.\u003c\/p\u003e\n\u003ch2\u003eThermal Stability and Applications\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eThe heat deflection temperature (HDT) is 46 °C at 0.45 MPa and 42 °C at 1.82 MPa, which restricts the use of parts to applications without prolonged heat exposure. Water absorption over 24 hours remains limited to 0.50%. The resin is positioned for prototyping, functional parts not thermally constrained, and series production where material cost control is a criterion. ISO 10993 biocompatibility data is available upon request from the manufacturer.\u003c\/p\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eMaterial\u003c\/th\u003e\n\n\u003ctd\u003ePhotopolymer resin\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eAppearance\u003c\/th\u003e\n\n\u003ctd\u003eTransparent\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eViscosity at 30 °C (cone\/plate rheometer)\u003c\/th\u003e\n\n\u003ctd\u003e400 mPa·s\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eViscosity at 50 °C (cone\/plate rheometer)\u003c\/th\u003e\n\n\u003ctd\u003e120 mPa·s\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eLiquid resin density (ASTM D4052-18a)\u003c\/th\u003e\n\n\u003ctd\u003e1.08 g\/cm³\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eCured part density (ASTM D792)\u003c\/th\u003e\n\n\u003ctd\u003e1.12 g\/cm³\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eTensile Modulus (ASTM D638)\u003c\/th\u003e\n\n\u003ctd\u003e1500 MPa\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eTensile Strength (ASTM D638)\u003c\/th\u003e\n\n\u003ctd\u003e35 MPa\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eElongation at Break (ASTM D638)\u003c\/th\u003e\n\n\u003ctd\u003e20 %\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eFlexural Modulus (ASTM D790)\u003c\/th\u003e\n\n\u003ctd\u003e1700 MPa\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eFlexural Strength (ASTM D790)\u003c\/th\u003e\n\n\u003ctd\u003e60 MPa\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eNotched Izod at -30 °C (ASTM D256)\u003c\/th\u003e\n\n\u003ctd\u003e14 J\/m\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eNotched Izod at 23 °C (ASTM D256)\u003c\/th\u003e\n\n\u003ctd\u003e24 J\/m\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eUnnotched Izod at 23 °C (ASTM D256)\u003c\/th\u003e\n\n\u003ctd\u003e720 J\/m\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eNotched Charpy at 23 °C (ISO 179-1)\u003c\/th\u003e\n\n\u003ctd\u003e1.4 kJ\/m²\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eHDT at 0.45 MPa (ASTM D648)\u003c\/th\u003e\n\n\u003ctd\u003e46 °C\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eHDT at 1.82 MPa (ASTM D648)\u003c\/th\u003e\n\n\u003ctd\u003e42 °C\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eShore D Hardness (ASTM D2240)\u003c\/th\u003e\n\n\u003ctd\u003e80\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eWater Absorption 24 h (ASTM D570)\u003c\/th\u003e\n\n\u003ctd\u003e0.50 %\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eBiocompatibility (ISO 10993)\u003c\/th\u003e\n\n\u003ctd\u003eData available upon request\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\n\u003c\/table\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cul\u003e\n\n  \u003cli\u003eVat photopolymerization processes (SLA, DLP, MSLA)\u003c\/li\u003e\n\n\n\u003c\/ul\u003e","brand":"BASF","offers":[{"title":"1 kg \/ Clear","offer_id":57323360190808,"sku":"300106","price":74.0,"currency_code":"EUR","in_stock":true},{"title":"1 kg \/ Gris","offer_id":57323360223576,"sku":"300203","price":74.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0938\/8979\/0296\/files\/basf-ultracur3d-st-80-tough-resin.jpg?v=1779193924","url":"https:\/\/3dprint.shop\/en\/products\/basf-ultracur3d-st-80-tough-resin","provider":"3dPrint.Shop","version":"1.0","type":"link"}
