Resione F69 Black Flexible 3D Printer Resin: High Elongation Rubber-Like MSLA Resin
Resione F69 Black is a flexible MSLA photopolymer resin formulated for engineers, product designers, and hobbyists who need printed parts with genuine rubber-like elongation and tear resistance. It is suited to seals, gaskets, flexible connectors, figure accessories, tyre models, shoe samples, buffers, and dampening elements where the material must flex, compress, and return repeatedly without tearing or fatigue failure.
F69's defining specification is its elongation at break of 255%. At this figure, a part can stretch to more than three and a half times its resting length before failing, which is in the range of natural rubber and TPU compounds rather than standard photopolymers. This elongation is what enables F69 parts to be folded, stretched, and compressed thousands of times without cracking. Tear strength of 47.2 kN/m is the second critical figure: high elongation without tear resistance produces a resin that stretches well but fails suddenly at stress concentrations like sharp corners, thin walls, and fastener holes. F69 is specifically formulated to combine both properties, which is what determines whether a flexible gasket or seal survives assembly and service. Shore A hardness of 60 to 75 places F69 in the medium-soft rubber range, comparable to a car tyre sidewall, firm enough to hold printed geometry and surface detail under light load, soft enough to flex and return at room temperature.
Tensile strength of 7.9 MPa and elastic modulus of 2.0 MPa reflect the low-stiffness mechanical profile of a true flexible resin. F69 is not an ABS-like or semi-rigid material: it is a rubber substitute, and these figures reflect that correctly. One important characteristic: F69 hardens significantly below 20°C. At approximately 5°C the resin transitions to a hard, impact-resistant state. Parts intended for flexible use should be deployed in environments above 20°C. Below that threshold, the flexible properties diminish progressively. F69 can be blended with Resione rigid resins including K, M58, M68, and G217 to tune hardness upward for applications requiring a stiffer durometer. Compatible with all MSLA and DLP resin printers. Post-cure with 385 to 405nm UV for 20 to 40 minutes. Recommended layer height 0.09mm for flexible parts.

Frequently Asked Questions
It's a flexible rubber-like MSLA resin for parts that need genuine elongation and tear resistance, such as seals, gaskets, flexible connectors, tyre models, shoe samples, buffers, and dampening elements.
Elongation at break is 255%, meaning a part can stretch to more than three and a half times its resting length before failing, in the range of natural rubber and TPU rather than standard photopolymers.
No. Tear strength of 47.2 kN/m is specifically what prevents sudden failure at stress concentrations like sharp corners, thin walls, and fastener holes, which is a common failure mode in flexible resins that only optimise for elongation.
Yes. F69 hardens significantly below 20°C and transitions to a hard, impact-resistant state at around 5°C. Parts intended for flexible use should be deployed in environments above 20°C.
Yes. F69 can be blended with Resione's rigid resins, including K, M58, M68, and G217, to tune hardness upward for applications that need a stiffer durometer while retaining some flex.
It works with any MSLA or DLP resin printer between 385 and 405 nm. Recommended layer height is 0.09mm, with post-cure of 20 to 40 minutes.
Keep it at room temperature in a dark, ventilated space away from direct sunlight. After printing, store used resin in a closed, opaque bottle and don't mix it with new resin. Wear gloves and a mask when handling it, and wash any skin or eye contact with plenty of water.
Yes. 3D Cast is Resione's official Australian distributor, so you're getting genuine F69 Black with local support, not a grey import.
