With a Shore hardness of 40A, it produces soft, bendable components with pronounced elasticity. Custom shapes can be developed without first making a casting mould.<\/p><p>Application examples include bellows, soft grippers, protective pads and seal prototypes. Complex contours and tailored contact surfaces can be produced directly from a digital design. This makes the material particularly useful for rapid iterations and developing small quantities of functional silicone components.<\/p><p>Material-specific cleaning and post-curing are essential to the finished result. For seals and grippers, contact geometry, deformation range and the surrounding medium also matter. Resistance and function are assessed for the intended application; the material alone does not establish leak-tightness or a particular service life.<\/p><p class=\"material-description-sources\">Material information: <a href=\"https:\/\/formlabs.com\/de\/products\/silicone-40a-resin\/\" target=\"_blank\" rel=\"noopener noreferrer\">Formlabs<\/a><\/p><\/div><h2>Application ideas<\/h2><ul><li>Bellows and flexible connectors<\/li><li>Soft grippers and contact surfaces<\/li><li>Seal and protective-part prototypes<\/li><li>Custom silicone parts in small quantities<\/li><\/ul><h2>Properties and test conditions<\/h2><table><thead><tr><th>Property<\/th><th>Value \/ condition<\/th><\/tr><\/thead><tbody><tr><th>Manufacturer \/ grade<\/th><td>Formlabs \u00b7 Silicone 40A Resin  \u00b7 Identity from input list; see PDF for version<\/td><\/tr><tr><th>Tensile strength<\/th><td>5 MPa \u00b7 ASTM D412-06 Type C, 500 mm\/min; V1, Rev. 02, 2024-07-01; Form 3, 100 \u00b5m; wash: 20 min, 80% IPA\/20% butyl acetate; Form Cure: immersed in water, 30 min \/ 60 \u00b0C<\/td><\/tr><tr><th>Elongation at break<\/th><td>230 % \u00b7 ASTM D412-06 Type C, 500 mm\/min; V1, Rev. 02, 2024-07-01; Form 3, 100 \u00b5m; wash: 20 min, 80% IPA\/20% butyl acetate; Form Cure: immersed in water, 30 min \/ 60 \u00b0C<\/td><\/tr><tr><th>Shore hardness<\/th><td>40 A \u00b7 ASTM 2240; V1, Rev. 02, 2024-07-01; Form 3, 100 \u00b5m; wash: 20 min, 80% IPA\/20% butyl acetate; Form Cure: immersed in water, 30 min \/ 60 \u00b0C<\/td><\/tr><\/tbody><\/table><p>Source review: 2026-10-03<\/p><h2>Limitations and post-processing<\/h2><p>Suitability depends on geometry, orientation, print profile and material condition.
