## Description

desertcart.com: Siraya Tech Tenacious Flex 3D Printer More Flexible 405nm UV-Curing Resin with Faster Rebound High Impact Resistance High Precision Tough Standard Resin for LCD DLP 3D Printing (1kg, Flex Black) : Industrial & Scientific

Review: Great strong resin with the right settings - This resin is xlnt and prints beautifully with the correct settings. One thing to note is this resin needs to be used at least 26Deg Celsius for best results. At first I tried it and room temperature was 22 deg and I got bad cracks and layer separation. Then I bought a resin printer heater and set it to 27 deg c and let the resin in the vat and the printer warm up for 30 minutes then printed and then everything was perfect with no setting changed beside the temperature. Strong with a little bit of flex. Odor is I would say medium compared to others, It's not odorless but also not strong as well. So I would say medium-low odor compared to other resins so all in all very good. Sirayas stock settings work well on the MONO M7.
Review: Mixed with cheaper resin for breakage reduction - Great resin to mix into the cheaper abs to reduce breakage works well on my ELEGOO

## Features

- Soft, Rubber-Like Flexible Resin - Siraya Tech Tenacious Flex Black is significantly softer and more rubber-like than the classic Tenacious resin. This new formulation offers faster rebound and incredible elasticity, perfect for flexible and resilient 3D prints.
- Enhanced Flexibility and Rebound - Withstands extreme bending and compression, quickly returning to its original shape. Its superior elasticity compared to the original Tenacious resin allows for more dynamic and flexible prints.
- High Impact Resistance - Designed to keep your models resilient and protected. Exceptional impact resistance ensures that accidental drops or impacts don't cause deformations or cracks. The combination of strength and flexibility makes printed objects durable yet not brittle.
- Specialized Applications - Ideal for projects requiring high flexibility such as soft grips, gaskets, shock-absorbing components, and pliable prototypes. Note: May not suit all applications where the original Tenacious resin is typically used.
- Excellent Resin Additive - Mix Tenacious Flex Black with other resins, including tough resins, to boost impact resistance and flexibility. A small addition can significantly enhance the properties of your prints.

### ⭐⭐⭐⭐⭐ Mixed with cheaper resin for breakage reduction

Great resin to mix into the cheaper abs to reduce breakage works well on my ELEGOO

### ⭐⭐⭐⭐⭐ A great flexible resin that adds impressive impact resistance.
*by N***R on June 24, 2019*

This resin isn't rubbery. Let's get that out of the way first off. It's not like printing with NinjaFlex on an FDM printer. Parts that are made with this resin will deform, but it takes a little effort, and they go back into shape, but it takes a little time. They are more like soft plastic than rubber. But that deformation and give makes them incredibly strong and able to withstand heavy impacts. This would be a great material for outer casings or bumpers or tubes that needed to have some give to them. Resin from resins printers is often really brittle, and this can be added to some other resins to make them much more usable and less liable to break. You don't have to print with 100% Tenacious (although the items I've posted above are), as you can mix it in to add impact resistance to other resins -- and that's really where its primary value lies. Alone, it's a kind of whitish/clear resin that's not clear enough to be see through, but not opaque enough to be white. It's a bit soft, so it can scratch relatively easily. It doesn't yellow heavily, but it's more the colour of 'natural' PLA filament. It also has a kind of strange refractive colour that looks very blue to purple in daylight. I'm not sure what causes that, but it's interesting. Overall, though, I'm super pleased with this resin. It's a great addition to the arsenal of Siraya resins (Blu being the one I use most, followed by Sculpt and Tenacious in a head to head with both of them being more commonly used as additives to other resins for my stuff). It's a spectacular flexible resin for the price.
