Siraya Tech Blu - Tough Resin 3D Printing with High Toughness Resolution Strong and Precise 405nm UV-Curing 3D Resin for LCD DLP (Emerald Blue, 1kg)

First off, i want to take a star off just for the sake of being mislead, its not 1Liter, its alota bit less, its about about .8L so it does feel like we're being skimmed. I've purchased two bottles so far and they were equally under filled. But. I'm blown away with the performance that its created a bias. I printed a face mask @ 1mm wall thickness with 20% infill, and dropped it from about 4m, it did scuff, but no cracks, no breaks, nada. Its not indestructible, but it surely does hold its name as a premium resin. PLA+ or Fast resin equivalent would have shrapnel'd at that height. Its resolution is decent, but it tends to warp severely around the supports to the point it will make a flat surface look like a bee sting, so alot of supports will severely distort your item, the plus side is sanding is very simple and can easily be smoothed out; on the downside this means it also scuffs very easily, so you may want to spray your parts with a clear to give it some scuff resistance.

Blu is the strongest 3d resin I've ever tried. coupled with the price this resin is unbeatable. if you haven't heard of blu or siraya tech try them out; their resins are great and have different color options. they also test their resins on different machines and give you print settings and cure times for each of their products via website.

Really strong resin and easy to print! I didn't have a heated tank and it printed perfectly. Just incease exposure times and lower lift speeds and increase lift distance it it prints perfectly!

I would one hundred percent recommend this resin for functional parts. The parts are incredibly strong and aren't brittle at all. Not sure I would recommend it for miniatures or busts but I have seen people get decent results. Removing supports is generally harder than I have experienced with other resins because the stuff is so damn tough and flexible. From a usability standpoint it can be a little tough to work with. It doesn't smell that bad. It has a kind of almost minty smell but the smell is really strong and lasts a long while. The resin itself is incredibly sticky and oily in it's liquid form and is difficult to clean up. Usually with most resins I am able to wipe most of it away from the vat and spray the rest off with a small squirt bottle of IPA. This stuff requires a lot more labor to clean up. I haven't had a lot of experience with this resin yet but using a compliance matrix test print I arrived at 3.75 seconds exposure per layer for this resin and all other settings default

Nice

Something about the composition of this resin has been significantly altered since I bought my initial bottle about 5 years ago, when I got my first printer. I still have the original Rook test piece I printed when I unboxed and set up the printer, with no post-processing except the solvent bath and post-curing. Comparing them side-by-side, there is a massive difference in color and surface finish, with the new resin being much more transparent, more green, and having <VASTLY> inferior finish quality. The frankly awful finish of the new resin despite me now having access to an ultrasonic cleaner, is bad enough to warrant a 2 star rating. However, on top of that the higher transparency of the new version results in light bleeding through cured layers, and curing any resin that was trapped on surfaces behind the current layer. This coupled with the resin's extreme viscosity causes things like screw holes and standoffs to become filled-in and functionally useless. I'm using a Phrozen Sonic Mighty 4k. I heated my build chamber above 35C with this new resin by running the heating element at full blast. After a few failed prints, I initially thought I had simply forgotten how hard this resin is to work with. I slowed the lift speed down to just 20% of what it was to reduce suction, and tripled the cure time per layer, to little effect. The Rook, was printed at room temperature, on an Elegoo Mars v1, with default settings. This printer was so comparatively terrible compared to my Mighty that it wasn't even worth keeping to run both simultaneously, and I gave it away to a friend. This is <not> a printer issue, I am 110% certain. I <cannot> overstate how inferior this new version of the resin is compared to the original, and I am deeply saddened and disappointed by the sheer fall in quality of the product that put Siraya Tech on the map. It was a perfect match for my controller project, and I just... can't use it anymore, because they ruined it.

I bought this to print some small functional parts that needed good strength without being brittle. This resin far exceeded abs like resin that I had tried previously.

I have used alot of different resins and this is by far the best. Low scent and almost zero failed prints. Even printing in my cold basement it works everytime! It's also much stronger and less brittle than other resins I've used.

Casi termino la botella, ¿mi conclusión? Gran resina, sin impresiones fallidas, sin deformaciones, impresiones fuertes y estéticamente agradables. Como la resina es bastante espesa, la imprimo a 35°C con el calentador de mi cámara de resina. Tenga en cuenta que a esa temperatura debe reducir el tiempo de exposición.

このレジンで作成したものはかなり… 異様な強度です。 浴槽の破損した水道管トラップとして作成、取り付け後にちょっと設計を間違えていたことに気がついて取り外そうとしたところ… 硬い。 厚さは最高でも4mmでしたが、ハンマーとマイナスドライバーで何度叩いても割れない。 最終的に30分は叩き続けたり、はまりこんでいたステンレス製の水道管を叩き広げる暴挙でどうにか抜去。 中々に間抜けな所業ですが、そのくらい硬く粘り強いレジンです。

It's not flexible like they say but it's strong. Input 10% in the regular resin to make the prints stronger.

Prints well, but by far the stinkiest resin I owe.
