Siraya Tech Fast ABS-Like 3D Printer Resin 405nm UV-Curing Non-Brittle High Precision 3D Printing Liquid Standard Photopolymer Resin for LCD DLP 3D Printing(Grey, 1kg)

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.

Very reliable, consistent and strong build quality on fully cured prints. Bonus points for low odor.

I had to check out this resin for myself. I am using an Elegoo Saturn 4 Ultra and initially I used the settings from Siraya's website. Normal layer 2.2s. My model came out great but the supports were welded to the model. After running 16 calibrations from Table Flip Foundries cones of calibration, I concluded that my ideal normal layer curing time is between 1.6 to 1.8. I have been using 1.6 with no issues and I was able to lower my initial layers from 32 to 25 seconds. My supports come off so clean and buttery smooth and I dont have to fight to get my model of the plate. With my Freddy kreuger model, the blades on his glove are flexible and thats exactly what I would want this resin for. I also accidentally dropped the arm from the RE4 Regenerador from shoulder height to my hard tile floor and it did not break. As you can also see, the detail is great as well. Considering the price, it will not be my daily driver but will definitely be used for my most prized prints. Very happy with this resin and brand.

This resin works great, gives great detail and holds up really well in the tough department. My only negative would be the price, it is a premium product and the price reflects that; though there are cheaper options (few) that will give you similar or better results.

I've ordered this item numerous times, and it never fails to impress me. The quality is spot on, the prints hardly fail. My only Gripe would be that some of the smaller parts are a tad brittle, but overall they stand up pretty well. Will continue to order this product for all my printing needs!

This is a great printing resin and the color is awesome. Not fully transparent but looks great and holds up well

This resin is absolutely superb. I undertook a challenging 3D print job that consisted of very large pieces that needed precision to with interlocking gasket faces to be assembled. I tried several resins, but I was encountering multiple issues that resulted in print failures: separation from supports, drooping and distortion from the build plate, warping and bowing of the sides, and pitting from shrinkage. Basically nothing was turning out properly to my liking, and to get it even close required laying out a dense forest of supports just to get each print to hold on. And the stuff was soft and scratched easily even after curing. I switched to the Siraya Tech smoky black and the results are like night and day. I've had virtually zero warping and distortion, and parts are fitting together with precision that exceeded my wildest expectations. I've had zero print failures, and even am using significantly lower density of supports, which both saves on resin, and post print cleanup. In terms of cleanup, the resin sands, files, and polishes nicely, and the translucent color helps a bit with dry fitting prints. I'd recommend wet sanding in order to keep down on dust. After curing, the resin is sturdy and decently scratch-resistant. It feels something similar to Lego plastic. Surface takes primer and paint well. Printing on a Saturn 2, exposure calibration was a breeze (2.5 seconds). Additionally with the plug-in air filter, and odor is minimal.

Realmente no la compararia con ninguna, es una resina standard de la misma calidad que cuaqlquiera, el olor es similar a las de 30 euros, la calidad final igual, es quebradiza, si se te cae la pieza de la mesa se rompe, no entiendo la fama que lleva, perosnalmente no veo que sea una gran resina.

Súper buena para impresión 3d y trabajos dentales

J’utilise cette résine depuis 3 ans maintenant et jamais déçu! J’en ai essayé d’autres mais elle reste ma préférer, résine très fluide idéal pour l’hiver, la qualité est au top une fois bien calibré, peut d’odeur, et le prix et vraiment bon. Selon moi c’est la meilleure résine rapport qualité prix à ce jour et cela depuis 3 ans

Me ha sorprendido mucho para bien. En primer lugar, las dos resinas Siraya fast que he probado, huelen mucho menos que otras que he tenido. En cuanto a resistencia/tenacidad, no he hecho pruebas, pero en mi caso no es lo que busco. El acabado de la pieza, mate, en ese gris marino, y el nivel de detalle y resolución, son espectaculares. La figura está impresa con una Elegoo Mars 3 pro (4k) y estoy muy satisfecho con el resultado. Recomiendo 100%.

Excellente qualité. Répond parfaitement a mon besoin
