Review: 3d printing - Bought 3d printer and all accessories of which this is one for my son he is really pleased with the results so it’s five star rating from me
Review: The different colours have different hardnesses. - After purchasing two different colours I checked the Siraya Tech website for data sheets and realised that the different colours are actually different products which fall under the Tenacious label. Easy grey and navy are 73 shore D - Think ABS plastic or very hard rubber. Clear and obsidian black are 65 shore D harness - Think shopping cart wheel. Flex black is 70 shore A - Think shoe sole. By sheer luck I needed to print parts and flexible and hard prototypes and the two resins I've bought are flex black and clear, so no money wasted and the prints came out fine. Getting the softer material off my flexible print plate was a bit of a task but a sharp scraper did the job.

## Features

- HIGH IMPACT RESISTANCE - This Siraya Tech Tenacious 3D Printer Resin has high impact resistance, and the printed model is very flexible. The high impact resistance and toughness make the printed model not fragile and can withstand accidental drops from time to time.
- HIGH TOUGHNESS - This Tenacious 3D printer resin is the toughest resin among our products. Its extremely high toughness allows the printed thin objects to be bent 180° without breaking. And you can increase the toughness and durability of fragile standard resins by mixing them with other resins.
- SUITABLE AS AN ADDITIVE - Siraya Tech 3D printing resin is very suitable as an additive to increase the strength and elasticity of other resins. Siraya Tech Tenacious resin is often used to mix with other resins to reduce the fragility of other common resins and improve the durability of the model to obtain very powerful printing effect.
- WIDE APPLICATIONS - Siraya Tech Tenacious 3D Printing Resin is developed for most LCD and DLP printers and has a wide range of applications. Due to its high toughness and flexibility, this flexible resin is mainly used for miniature models, making braces, O-rings, washers, tabletop games, and mini-game models, swords, etc. It can provide more drop resistance and flexibility.
- EASY TO PRINT - Compared with other flexible resins, our Siraya Tech Tenacious resin is easier to print, and liquid resins are easier to dye. Best to print at 25°C or higher. This flexible 405nm UV-Curing resin is very suitable for making prototypes and flexible objects.

## Questions & Answers

**Q: Are the printed items feel sticky or attracts dirt?**
A: Freshly printed yes, but not once the print has been washed and cured.

**Q: What’s your experience been with the odour of this resin, is it really strong?**
A: Slightly stronger than what I normally use (Elegoo Grey) but stillnot nough to make it unpleasant.

**Q: can it be mixed with water washable resin?**
A: yes it can, however, a lot of water washable resins are susceptible to damages from water/alochol so you still want to be careful how you clean and dry the print

**Q: Does this mix well with phrozen aqua grey 8k resin? looking to maintain the detail but lose some of the 8k resin's brittleness.**
A: Yes, it can mix well with Phrozen Aqua 8K. 10-15% can go a long way

### ⭐⭐ Disappointing & certainly not the resin I was expecting/hoping it to be.
*by C***M on 2 December 2025*

Quite possibly the worst resin I've ever used, so bad that I ended up pouring the remaining 85% of it in to a large vat & curing it all before disposing of responsibly. I was quite excited to give this resin a go & expected good things in the hope it'd be a cheaper replacement for the Phrozen RPG resin i currently use. Lots of vigorous shaking to make sure it was well mixed & in to the vat which raised its temperature to what is recommended. Spent a couple of hours calibrating the resin to my printer (Elegoo Saturn 4 16k Ultra) & then ran a set of prints through it which were duplicates to ones I currently hold in stock (Phrozen RPG). Washed & cured the finished prints which had a glossy finish to them, almost translucent at the thinner parts, the detail was ok but nothing compared to what you get using Phrozen RPG resin. There's hardly any "flex" in the cured resin but probably just about enough to prevent easy snapping points of limbs. When I cleaned out the vat I found thick congealed resin as I poured it back in to the bottle, had almost runny jelly consistency to it along with some very thin cured strips. A very odd experience with this resin throughout , I wont be wasting my valuable time or money with it again. I gave it two stars as it did print to an ok-ish standard but certainly not of a good enough standard to sell via Etsy etc... I've added four images, two are using Tenacious & the other two are printed using Phrozen RPG.
