Siraya Tech Blu 3D Printer Resin High Toughness Resolution Strong and Precise 3D Printing 405nm UV-Curing Rapid Resin for LCD DLP 8K 3D Printer (Obsidian Black, 1kg)

I found this sauce to be a super-fluid, not superfluous fluid, and able to add super glued strength in a resin de jour consistent of 40% plant-based resin of the dirt cheap garden variety, 30% mid grade abs-like resin, topped off with this bottle before you. Results performed as well as high-end Nylon resins and had excellent detail to boot. Enjoy.

Elegoo Saturn user Like most reviewers of obsidian black I wasted a lot on failures. Which is unfortunate, as I need this resin for a project and it's not the cheapest. Finally I found one user who left a review with the settings Siraya tech sent them to try and it worked! They need to update their site with those settings! One issue I had as well was with supports. For heavy/denser prints you're going to need to increase the diameter of the tip of the supports and move them so the tip is at least halfway inside the print area. You may have to do a little filing to smooth the nubs, but it's worth it to keep your prints from falling away/disconnecting from supports. It is not a light or pleasant odor; it stinks! Respirate and ventilate! Other than that very good performing resin. Can take a lot of bend stress but not the most impact-resistant. Can take a bump, but I would not recommend for any application subject to multiple direct strikes.

While I had to return this resin because I wouldn't be able to use volatile cleaning fluids due to the odors, vapors and potential fire danger, I did do extensive research online which revealed that this resin is a high-quality resin which produces great results on many models of resin 3d printers.

In short, this is a phenomenal item. It prints well, the prints are tough as nails, and it sticks like glue to the build plate. One thing that I experienced that I haven't seen other people complain about - it made my eyes hurt, a lot. I had to shower and flush my eyes to keep them from burning. The scent is fine, a little sweet, and better than a lot that I've found, but I stopped using it because my eyes were killing me. Not a problem I've had with other Siraya tech resins, and I currently print with a fast Navy grey/Tenacious mix every day just fine. If I needed even more strength, I'd pick up more but I'd get some chemistry goggles.

I've been experimenting with this resin for a few days to mixed results. Right now I'm giving it three stars, but I'm open to going up or down as I get my process dialed in more. Here are my observations: This resin is not actually black. While it appears black pouring out of the bottle, prints are more of a dark navy. It's an attractive color, but if you are looking for a true black, this is probably not a good option. Compared to other functional resins I've used, this one does produce very good detail. Durability is good, but the prints never get truly hard/rigid like ABS or other more plastic-like materials. The results are more akin to a very hard rubber, so if rigidity is what you are looking for, you might have to mix with another resin or look elsewhere. Compared to other resins, the smell is moderate, and cleaning and curing times are somewhat long. Another issue I've had with this resin is that it REALLY sticks to my FEP sheet, far more tenaciously than other resins I've used. To the point where I've had multiple bulky/sturdy prints pull themselves apart while printing rather than release from the FEP. And even when it does release, there is a very loud pop/tearing sound, indicating the printer is struggling to pull it apart. I've tried significantly longer layer times and slower lifts to middling success, and my next step will be to install a new FEP lubed with PTFE and see if it works better. Where I've managed to complete prints, they have come out pretty nicely and reasonably dimensionally accurate, but unless I can manage to bring the failure rate down, this resin will likely be more trouble than it is worth.

UPDATE: After Siraya Tech got back with me about the Blu Obsidian Black resin I worked with them on the settings. This helped some, but I was still getting failures. I then decided to try Vroom settings and that yielded in very successful prints. I wanted to share my settings here so if other are also having printing issues they can use these settings to test. Layer Height: .05 Bottom Count: 5 Exposure Time: 2.5s Bottom Exposure Time: 25s Transition Layer Count: 10 Transition Type: Linear Rest Time Before Lift: 0s Rest Time After Lift: .15s Rest Time After Retract: 1s Bottom Lift Distance: 7 Lifting Distance: 7 Bottom Lift Speed: 180 Lifting Speed: 180 Bottom Retract Speed: 200 Retract Speed: 200 Hope that these settings helps others... =============================================================================== I had high hope for this resin. However, failure after failure. Performed 20 calibration test, 10 test prints...all failures. Tested exposure time supplied from Siraya Tech, and e everything from 1s to 6s...resin at 87 f. Just don't understand why it is such a pain. I reached out to Siraya Tech...nothing back after days.

This part doesn't stick to the build plate and it's extremely smelly. I would stay far away.

I needed to print some fairly transparent parts for a client and their only request was to get something see through but not clear. I immediately turned to Siraya Tech as I have used their line of transparent resin products before with great results. Parts turned out amazing. I even mixed a batch up with some Tenacious for a couple of sample parts to give the client some flexibility. All of the parts printed are on an active functional prototype and are reported to be working as intended. Siraya Tech has been my go to resin for the last couple years, especially for clear parts. I have never had a bad batch of resin nor have I had print failures due to resin issues from their products. I HIGHLY recommend their resins.

Hele krachtige resin. Let op: goed uitharden! Tijdens het uitharden verwarmen is nog beter. Getoonde onderdelen zijn Trident onderdelen van een Akai bandrecorder. De onderdelen zijn wel wat doorzichtig.

I've tried everything to get this resin to be useable, firstly it prints ok no issues at all with it but then that is where the issues start. I've tried nearly all methods of getting this resin to clean correctly. Brand new 99% IPA, dunking, scrubbing, water baths and back into IPA but it still remains with a layer of uncured resin. Curing attempts then become the next hurdle, I've had parts 0.7mm thick under 405nm UV for nearly 50 minutes and they are still not cured! I've lost all motivation and will to work with this resin again and I'd certainly not be for the price and work I've lost because of such. I've asked across numerous forums and there seems to be this trend of not being able to get it to clean.

Reçine depodamı bekletilmiş ben baskı aldımda dengesiz baskılar aldım belli bölümleri destekleri ayrıldı + kürlememe rağmen yapışkanlığıda geçmiyor aynı markanın 12k reçinesinde problem yaşamamıştm neden oldu bilmiyorum 🗿

Did not have to go crazy on the supports. Very difficult to clean the black completely out of the vat if you have a light coloured print after this one. Go for a higher exposure than usual. Even though I almost doubled the exposure I usually use, the print was under exposed, tacky, supports left large pin holes. Took some fixing up. Cured it more than double time. It is a tough resin though which is what I wanted.
