Siraya Tech Fast Mecha ABS-Like Scratch Resistant 3D Printer Resin 405nm UV-Curing Non-Brittle High Precision 3D Printing Liquid Standard Photopolymer Resin for LCD DLP 3D Printing (Mecha White, 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.

I primarily print miniatures and other TTRPG items. I've only tried a few resins, but this one has given me the best results. Compared to other resins, the smell isn't overpowering (personally, I still wear a respirator, but once I have my printer tented and I take my mask off, any residual odor in the air dissipates almost immediately). It's also low viscosity and cleans up better than every other resin I've used. I go through way less IPA with this stuff! I do find the processed prints to feel brittle... even with the proper exposure time and only a minute of UV curing. I might try mixing in some Tenacity as other reviews have recommended.My only complaint: The bottle. It leaks constantly from beneath the cap, especially when I'm warming the resin before pouring it in the vat. I wipe out the cap and wipe off the neck of the bottle, but no matter what, there's always residual resin around the cap. Siraya, please fix your bottle design!

This is a great printing white resin. I've tried many, this one has given me the least amount of print failures and seems the least error prone than most of the whites I've tried. Also low odor compared to others (do not confuse this for "safer" as all resins are not safe and full PPE should be worn and proper ventilation set up).The only thing I don't like about this white is that is slightly translucent and it yellows VERY quickly during curing. I've had trouble minimizing the yellowing during my cure times and still trying to dial it in. Since things I print are often used in the sun, I'm concerned about the long term ability of the resin to not yellow even further. But overall very happy with this resin as it seems to offer many less headaches than other whites.

Love this stuff!It's very reasonable to print with and the fumes are reasonable. Excellent mechanical properties for items that you're going to handle and use.Still prone to tension cracks like any SLA print but it's much stronger overall and feels like a substantially higher impact toughness than regular or water wash photopolymer resin.I highly recommend this resin for use in MSLA printers, works great in my older Mars 3 and my Phrozen Sonic Mega 8k.

Been using this with my Uniformation GKtwo resin printer, the details are great. Its not brittle like another resin I tried after, so if it ain't broke, don't fix it right? The liquid doesn't have a heavy smell either, my ventilation set up makes it virtually no smell. After it cures, it is easy to sand. It also seem easy to scratch so be careful taking prints off the build plate before you cure it. I also love the dark navy grey color on the prints.My main complaint about this resin is that it doesn't seem to fill all the way to 1kg. After buying 3 bottles of it, it always came to about 850kg (from the slicer software perspective), and I've always let my prints drip dry so it shouldn't have had much waste. Minor complaint is that the cap will leak after you open it the first time, so between prints when you shake the bottle, I ended up having resin drips from the cap after I screwed it back on tight. Solution was simple: put it in a zip lock bag after initial use. Until I find a cheaper alternative, I'll keep going back to this resin as my main choice.

Llegó a tiempo y bien empaquetado. Compré varias y cada resina venía bien protegida en cajas individuales y con soportes extra.Los envases venían muy inflados por los gases, pero la resina está perfecta, solo hay q tener algo de cuidado al abrirla.Respecto al peso, me daba la impresión de que no iba a pesar los 2k, así q lo verifique con báscula, para mi sorpresa, pesaba lo correcto.La resina perfecta, lo esperado de Siraya tech, es un producto original

I have tried a few different resins now, but this one (which was the first one I tried) was incredibly easy to print with. Very short exposure time (2.0s on a Saturn 2), and no failures. I did however notice that the smell is pretty strong when compared to Elegoo's ABS-like. A bit pricier too.

Super résine qui imprime rapidement une fois qu'on installe les paramètres de la marque. Elle sent moins que celle que jutilisais précédemment. J'en suis très contente, très bonne qualité

In mijn ervaring zeer goede details, supports failen minder dan met andere merken die ik al gebruikt heb, en het voelt steviger aand omdat hij iets leer flexibel en dus minder broos is dan sommige andere merken

Se cercate una resina con un ottimo rapporto Qualità Prezzo eccola! il formato da 2kg è il più conveniente.
