Fast ABS-Like Tough Grey 3D Printer Resin, Enhanced Durability for 3D Printing, High Impact Resistance, Smooth Finish, Ideal for 4K/8K/12K LCD DLP SLA 3D Printer - 2kg

I'm in the middle of an engineering project (basically a custom RC plane), and needed some small, precise parts that still need to take decently significant loads. Of course print quality and resolution is a more a matter of what printer you have, but I can say this stuff printed fantastically on my Photon Mono S with the settings recommended by Siraya Tech (you can find a spreadsheet on their website). The parts that I got are incredibly strong. I know this is an ABS-like filament, but I've legitimately gotten better performance out of these than actual ABS from an FDM printer. That is most likely because printing orientation does not matter nearly as much, so the parts turn out mostly isotropic (equal strength in all directions). I'll describe some of the cases I used this for below.MY USE CASES:One of the parts was a stepper motor gear (28BYJ-48) that needed to deal with up to 0.1N*m of torque. I can tell after a lot of use, the section that meshes with the stepper pin has worn down from perfectly tight, to having maybe 3-5 degrees of slack, but it's still perfectly usable.Many of the parts require linkages between them, so I printed 5mm pins. In my case, I had to reduce the size of the pins to about 95% to avoid clearance issues, but once they were in place the pins had very little friction while still providing very tight joints. Additionally, those pins could handle a surprising amount of shear force. I tested with a 5kg weight, so statically that's about 2.5MPa, but I also drop tested with that rig, so it could have easily reached 25MPa at one point.CLEANING:Specifically regarding this resin, you have to empty and clean your vat within 2 days if you don't plan on printing again. This stuff will separate into layers in about that time and becomes harder to clean off the vat. Also, water curing has yielded good results for me.If you've never resin printed before this part is for you, otherwise move along:Cleaning the prints is quite a hassle. They come out coated in liquid uncured resin which is, in the case of this resin, definitely a nasty skin irritant and potentially toxic if ingested (most resins are). You'll need LOTS of isopropyl or denatured alcohol, at least like 2 or 3 tubs or large tupperware containers, lots of paper towels, definitely more gloves than your printer comes with, and some way to get rid of the fumes. The alcohol is smelly enough, but this resin is definitely nasty stuff to be around. You have to be very careful not to get it on your skin or other surfaces (as it is quite drippy off the printer). With this resin, I got the best results by cleaning with alcohol from a spray bottle, then rinsing in water for 30 seconds, and then submerging in a cleaner tub of water before leaving in the sun (for 45 minutes) or shining with a bright UV light (1 minute or more, flipping the part with tweezers). I tend to keep one tupperware container for the alcohol cleaning process, which is very thick with uncured resin, one container for dirty rinse water, and one for clean water (and a bonus extra container to place all my contaminated tools and paper towels). I can usually run with this setup for several prints without changing out the liquids, which is nice because you CANNOT wash this stuff down the drain (unless you want even more micro-plastics in the ocean), and it absolutely has to be cured before you dispose of it. I typically save my 2-liter bottles and old mouthwash bottles, dump everything into those, and leave them out in the sun for a day before putting in the trash.CONCLUSION:If you can deal with the hassle of cleaning and PROPERLY discarding of the waste, then this resin produces results that you simply cannot get with other printing methods. Sure, FDM printing is less toxic and usually easier to get larger prints with, but the precision and speed of resin printing is unmatched. Usually that comes at the cost of poor physical proteries, but with this resin, you can get really small, precise parts with fantastic physical properties.

I have used both the "regular" and the "tough" variant of this (Amazon lists them as colors.) The difference seems to be that the tough has some of Siraya Tech's Tenacious resin added. This resin is also excellent, and it gives the prints a degree of flexibility -- they are not brittle at all, and they print perfectly even with "light" supports.The "tough" version is absolutely great for printing DnD Miniatures. They come through clean with light supports, and they are more than adequately detailed to make the end product depend on your painting skills more than your printer. Best of all, you can drop them without fear, and I have yet to have one fail during the printing process.Highly recommended.

This is my go to. I've tried pretty much every other resin out there, but for reliability and durability, this is the only one I use now. Great for miniatures and other models, and mixes great with Siraya Tech Tenacious for extra flexibility and durability. 6 different printers, multiple brands of printers, but only this resin works on them all with little tweaking and minimal failures.

I find this a very reliable resin to print with, even in a chilly environment. I only remove a star for the appearance as the material is faster to separate than other resins. Once primed, the prints look great, but they aren't as attractive on their own due to streaks of grey.I love this concept of using the Navy Grey Fast and mixing some Tough in. I only wish Siraya Tech would do the same with Tenacious

I love this resin!!! its really easy to work with, especially when you fine tune your settings. I would ignore whatever recommended settings SIRAYA Tech gives on their website. I use an exposure of 3.6 to 3.6 and get really nice crisp details. It barely has a smell to at all. It is really a joy to work with. Everything below was printed with this resin, I used 3.6 on the Orc Female and for the bust I used 3.2.Note the models were printed on a Elegoo Saturn S.

This has been the most reliable resin that I’ve purchased, did not have to fiddle with many settings for printing using it. Good consistency and doesn’t have much settle as long as you shake it like it instructs before use ( usually I leave it in storage vat and stir before use which turns out perfect ). Prints come out at good quality as well, especially larger prints. Also comes in a nice container for pouring and storage.
