  • Goodbye purple, hello BLUE
Color: Purple 1000g
The media could not be loaded. 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. ... show more

  • great stuff
Color: True Blue 500g
I've heard the Purple is a little more difficult, but the blue is great when you learn the system. I'm using an Elegoo Mars 4 and printing at 60 seconds for the bottom 5 layers and 6 seconds for the rest and I've found that around 80° for the resin and print area is good, much cooler and you'll have issues. The prints come out fantastic, probably cleaner than the Sunlu Standard I use for other things, however, it is a bit brittle, and I'm learning to design my runners into the print because it doesn't like to grip wax very well. I'm using Ransom & Randolph Ultravest100 gms/39gms sit overnight and 10 hour burnout next day to 1350°F and vacuum casting bronze at 2000°F; so far having very good results! The three in one vacu-cast system sold on Amazon is working great for this too. ... show more

  • prints failed for me regardless of what i tried
Color: True Blue 500g
could not get this resin to print consistently or properly despite multiple attempts i even switched back to normal resin just to make sure my printer wasn't malfunctioning and those prints were a walk in the park but this castable resin kept failing no matter what settings i tried, i ran a heater, had the printer leveled properly and tried multiple different settings and supports recommended from various users who've had success with this resin and still no luck, time for me to try a different brand. ... show more

  • Worked Great for casting engagement ring
Color: True Blue 500g
I purchased this to make my girlfriends engagement ring, and it printed well took a little bit to dial it in, but I ended up with a great print that I was able to give to the ring maker to cast and the ring turned out amazing, she loved it. The curing process after you print can be a bit much to make sure it cures evenly. The resin it's self stains so make sure to put protection on. You can use isopropyl to clean it easily tho. It is a good price for the quality you get tho. Most of these castable resins can run a pretty penny. The print after curing will be brittle so keep that in mind. ... show more

Me ha servido para mis procesos de fundicion, las impresiones quedan con un muy buen nivel de detalle, lo más importante es la parametrización de la impresora que usen.
