Review: Goodbye purple, hello BLUE - UPDATE 11/2/22: I work with this resin exclusively, and since I have so much experience with it, I figure that I’ll do updates for those of you who are just trying it or are having difficulties. This update is just to tell you guys about a successful experiment I tried. I was running low on blue, so I tried mixing blue and purple together and it honestly printed better than either one by themselves. I did about a 50/50 mixture, let it get fairly hot from sitting in super hot water from the sink for about 10 minutes. I don’t know if this is necessary, but I shook the F&$K out of it just to be sure. The resulting prints are shockingly good, I think that the addition of the purple give the pieces more rigidity, while the blue ensures cleaner models and supports. I haven’t done a cast with it yet, but I’ll let you know how it burns out. If that goes well, I will definitely be doing this from now on UPDATE 10/17/22: If you are about to hit that “buy now” button on the purple, STOP, get the blue… you’ll thank me later. Literally everything about the blue is light-years better than the purple. I went through an entire kg of purple without ever getting anything I was truly happy with (see below for old review). I was never able to achieve prints that didn’t have big build ups of unwanted resin, the post processing was ridiculous, and even after cleaning the models THOROUGHLY, I still wouldn’t get consistently clean burn outs. The Blue has none of those issues. Haven’t had a single build up around supports, the supports break cleanly from the models, post processing is easy and much faster, and best of all, the burnout is clean. The only downside of the blue is that the models are VERY fragile before post curing, so you have to be super careful. I have heard you might be able to get away without post curing at all, but I would recommend it for the simple fact that it strengthens the models significantly. If Blue is in stock, spend the extra money. I am maybe 1/3 of the way through a 500g bottle and I have achieved more usable prints than with an entire kg of the purple. OLD REVIEW OF PURPLE: I go back and forth with this resin, there are things that I like and things that I really don’t like. For the price, this stuff is good. Not great, good. If you do everything right (I’ll come back to this) you’ll get pretty good resolution, it’ll be easy to sand/finish, and you’ll have a clean burnout. But, in order for all of that to be achieved, you really have to follow these rules. First, and probably the most frustrating, is finding the proper settings. I found it really difficult to get my settings correct and I wasted a lot of time and resin doing so. I use a Mars 3 and my settings are as follows (I hope this helps someone): Layer size: 0.05micron Bottom layer count: 5 Exposure time: 5.5 Bottom exposure time: 100.00 Choose “light off delay” under the “waiting mode during printing” drop box and do: Light off delay: 2.000 Bottom light off delay: 5.000 Bottom lift speed: 50 Lifting speed: 50 Bottom retract speed: 100 Retract speed: 100 These settings have worked, but I still get a lot of resin build up around my supports which is a nightmare to clean up, if it doesn’t completely ruin the piece. These are also not the only settings I have ever tried, I have experimented with just about every reasonable combination and I haven’t been able to achieve clean prints without any globs of resin around the supports. So here’s a tip: try to position your piece and supports somewhere that will be easy to clean and won’t be the end of the world if not perfect. BE SURE TO PRINT AT 25-30°C or else you will have many failed prints! Next, you have to clean the pieces in a very specific way. No more than 30sec submersed in IPA, they recommend only using a paint brush to remove excess, and then immediately run under hot water for 30sec and then cold water for 30sec. This process has to be repeated until clean, and I find myself doing at least 6-7 cycles of this. It’s honestly pretty annoying. Next, post curing must be done in some sort of liquid with a similar refractive index as water, but NOT water, the resin is porous and the absorbed water can ruin your cast . They recommend using vegetable glycerin, but I had mineral oil on hand and it seems to work fine (more work to clean up so I’d recommend VG if you are going to buy something). You have to do this because the resin won’t cure in air, believe me, I have tried. You have to cure for at least 30 minutes, but I find myself having to cure for 1-1.5 hours, which is ridiculously long. Once it’s done curing, clean it off and be sure to dry it right away as to not let it absorb too much water. Be sure to have your burnout temp reach 1350°F and hold for 2-4 hours. Annnnd it’s just that simple! But seriously, this stuff is finicky and hard to get right, I’m almost done with a full kg and I’m still not completely happy with the results, but it works well enough if you are careful and methodical.
Review: Works great but has to be printed slow - Product works great but lift speed has to be under 60mm/min. I am using Anycubic photon mono x 2.8s exposure. 0.25 layer height. First layers 50s , and lift speed 1mm/s

### ⭐⭐⭐⭐⭐ Updated: This was an opened bottle!
*by J***S on August 14, 2022*

The company: Wow! What a great company and product, to say the least... Siraya tech went above and beyond to help me - to the point of giving me a free bottle of Cast! Not to mention the communication! This company isn't playing around! They know how to treat poeple and are genuinely concerned if you have any issues with their products. The product: I can't say that all of the failures I've had have anything to do with Siraya Tech's Cast resin or my Creality Halot Sky printer... There is definitely a learning curve with UV resin printing and if you think you're going automatically jump into casting resin, think again... This is without a doubt a challenging undertaking and if you're the type that is a bit faint hearted? Then this may not be the hobby much less, profession for you? That said, Siraya Tech with their Castable resin has done something great for 3d print hobbiests and business' transitioning from lost wax to lost resin casting. The quality of cured parts are absolutely stunning! You will not find another castable resin of this quality for $75 anywhere! Thanks again to Siraya Tech support team. They are truely good people and are very much appreciated in Northern California! Normally siraya tech is good stuff, but this bottle had fragments of print bracing in the resin! Someone used it and poured it back and returned it. Then it was sold to me! If I ever see this again from siraya tech or any other brand, they can kiss my arse goodbye! I never buy their product again! Also I could tell there was a problem with the resin. It was like something was added to refill because it printed very strange... I don't know if I'll use the rest of it..? Anyhow...
