FANTASTIC MIX RESIN
This is a must-have for me now. I mix it with Anycubic ABS-LIKE Pro 2, with fantastic result. No more brittle parts that break, now they bend a little and snap back. Great for minis.

Good product
Works as expected, clean print quality, documentation for initializing for printer was very close to perfect for my GK2.

The Obsidian Black is not completely black
The black is slightly translucent, which does not work for my purposes of printing model car parts such as wheels and floor mats. It's VERY flexible and tough, and will not tear, so that's awesome. But it's not opaque. At 2 ml thickness, you can see light through it, and the light is blue-ish.

Very high performing resin
Printed quick and easily on my Saturn S4 U, and had a nice flexibility to it when cured at room temp, but when cured in 60C water the hardness increases, and barely has any flex to it. It has a nice rigidity with enough elasticity which seems like it will resist shatter when under stress. Feels like it rivals Siraya Tech's Blu Nylon Black when it's been heat cured, which could make it a good value alternative. Has a nice transparent smoky blueish purple color.

Best 3D printer resin ever made!
Don't hesitate to buy and use Siray Tech resins, that's all I'm gonna say. I use Blu and Tenacious for my prints and am able to achieve absolutely unbreakable, functional, and durable prints with high detail and accuracy. These resins have almost no smell, they never break down if left inside VET for a long time, and they are easy to clean and pleasant to work with. Also, Siraya Tech's shipping and customer service is above and beyond.

Works great, smells like cancer
Work great as an additive (1/10th, by weight) to Phrozen Aqua 8k resin for better strength with miniatures. Only major complaint is it is VOC-y as the day is long. Seriously, get a better ventilation setup if you're using this stuff.

It is tough, but very difficult to use. Experience with opaque black.
The good- it takes on detail well and is semi flexible once cured. It seems as strong or stronger than most resins, and not brittle. Can be used for powertrain gears ect. The bad- bed adhesion is insane! It seems to weld itself to the build plate and is very difficult, if not dangerously difficult to get prints to come off. It is very soft and flexible off the build plate, and it will deform when trying to remove it, think thick room temperature tar. It will take a minimum of 90 minutes in a cure station to get it to firm up to a semi acceptable level. Overall-An interesting resin with unusual properties, yet I don't think I will ever use it again. Using an Anycubic Mono 6k. 2 layers at 25sec and each .5 layer at 2.5 sec. Don't use more bottom layers or longer exposure times as your print will not be even close to dimensionally accurate on the z axis.

Ottima resina gommosa. Quello che cercavo. Semplicemente spettacolare

Ive not tried printing with this resin on its own but i have been adding 10% Tenacious to an ABS-Like resin to reduce brittleness of the prints. So far results seem good, i will continue to purchase this resin for the same purpose.

Come resina “soft touch” è ottima, del resto come tutte le resine Siraya Tech. Purtroppo però la descrizione è estremamente fuorviante: QUESTA RESINA NON È AFFATTO FLESSIBILE, NEMMENO MINIMAMENTE. Al tatto risulta solo leggermente più morbida, ma non ha nulla di elastico o realmente flessibile. Si tratta piuttosto di una ABS-LIKE un po’ più morbida e meno rigida rispetto alle classiche, ma questo NON LA RENDE UNA RESINA FLESSIBILE. La mia valutazione sarebbe di 5 STELLE per la qualità complessiva del prodotto, ma solo 3 STELLE a causa della descrizione fuorviante, che fa pensare a una resina flessibile quando in realtà non lo è.
