Siraya Tech Blu Nylon Mecha - Tough 3D Print Resin, Scratch-Resistant, Nylon-Like Strength & Precision, High-Resolution 405nm UV Curing LCD DLP 3D Printer Compatible, 8K Capable (1kg, Nylon Mecha)

Product is OK, I made some knobs for my simpit panels (F18 project) that I needed to be translucid so that I could paint them partially and get light going thru some unpainted areas to get some markings on the knobs illuminated from below. Other than having a mild yellowish tint to it, it is translucid enough and result is good in term of toughness (it gets really hard), minimal shrinkage, smoothness and fine details. The adhesion to the printing bed was super strong so I had some difficulty removing the models but at least adhesion is not a problem. However be ready, this stuff is thick, sticky and hard to wash, even using 99% IPA, and stinks quite bad. I have a room dedicated to my project, I closed the door and open the windows as usual however forgot to turn off the central A/C and some air recirculated in the house and that bad smell went everywhere. Bottom line, sticky and hard to wash off the models and equipment (requires a long alcohol wash) and better have a well ventilated isolated room for using it.

This BLU resin is so much worse than the FAST green (actually yellow) resin that they are in entirely different worlds. Save $20 and just use the FAST green (yellow) for everything. Mechanical strength, machine-ability, etc seems very similar for each. The BLU requires heating to work, and when you heat the stuff it gives off even more horrible fumes. I really wonder if it contributed to the cancer I was just diagnosed with. The FAST resin works perfectly at room temperature, has little detectable odor, cures faster, produces finer details, and is easier to cleanup. Their is NO excuse for using this nasty BLU resin. They should put a skull and crossbones on the bottle. I would NEVER use it all all unless under a powerful fume hood.

This resin does result in much tougher prints, but they are far from accurate. I used their exact setup recommendation from their website and it still resulted in badly inaccurate prints. Printed on Elegoo MARS.

By far my favorite resin to use. The durability makes it perfect for prop and costume fabrication.

Using this resin with an Elegoo Mars with amazing results. Strength. Durability. Transparent Blue. This is it folks. There is a learning curve with this resin as is most new resins you will try. But at these prices, a failed print isnt a total financial disaster. Not the best smell but to be fair, I havent found a resin yet that i enjoy sniffing. I put my Chitubox blu profile in pictures, hope it helps.

Dont waste your money on this product! I tried all kinds of setting to get it to work but it didnt! Ive been using the Siara blu the blue/green color for awhile and it works perfect but this black one does not. The only way I got this black one to work is by mixing it with the blue one.

Ive had a hard time finding a resin that can hold up to stress in a project that has moving parts. Most resins are brittle and snap under moderate stress. I added Tenacious to toughen them up, but that caused the part to flex too much and eventually broke as well. In a last ditch effort I tried Blu and couldnt be happier with the results. Its a super thick resin, like honey. The smell is not as bad as Anycubic resins and it stuck to the plate beautifully on the first try. The part I printed is only slightly flexible and doesnt lose its shape or break under pressure. I normally clean my prints with iso and water, but water will make the print look cloudy, so you may want to avoid water if you want that transparent look. If this resin came in black or white it would be the only resin I ever use.

All around great resin for functional durable parts, but be aware it has a horrible smell, without a respirator I would not be able to even think of using this resin purely because of how bad the smell is.

Works very well

Models come out with good tolerances, takes a lot longer to cure than the regular resin. It is stronger than the fast printing basic resin, but its not as tough and flexible as I was expecting, still relatively brittle.
