Its resilience ensures longevity in applications where repeated flexing is common. Broad Compatibility and Ease of UseThis resin is formulated to work seamlessly with a wide range of 405nm LCD and DLP 3D printers. Its one-component nature eliminates the need for complex mixing, simplifying the printing process and ensuring consistent results. Siraya Tech's Rebound 55A is a high-performance 3D printing resin designed for applications requiring exceptional flexibility and rapid shape recovery. With a Shore hardness of 55A, it offers a softer touch than other flexible resins, making it ideal for producing parts that need to withstand repeated stress without permanent deformation. Key Features 55A Shore hardness for superior flexibility Fast rebound capability for quick shape recovery Compatible with most 405nm LCD and DLP 3D printers Professional black finish suitable for functional prototypes Ideal for shock-absorbing components and flexible consumer products Single-component resin requiring no mixing\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Siraya Tech\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eModel:\u003c\/strong\u003e ST0050\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eEAN:\u003c\/strong\u003e 0768924647571\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1200 g\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eBuy Siraya Tech -Rebound 55A Black - 1KG Resin on STRATO3D with fast shipping in Italy.\u003c\/em\u003e\u003c\/p\u003e","brand":"Siraya Tech","offers":[{"title":"ST0050","offer_id":55704348361044,"sku":"ST0050","price":73.6,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0957\/4331\/2212\/files\/Siraya-Tech--Tenacious-Lava-Black-1KG-Resin-32748_1.jpg?v=1777884141"}],"url":"https:\/\/strato3d.it\/en\/collections\/resine-flexible.oembed","provider":"Strato3D","version":"1.0","type":"link"}
