SUNLU High Toughness 3D Printer Resin, Enhanced Flexible 3D Printing Photopolymer Resin, 405nm UV Fast Curing 3D Resin for Most LCD DLP SLA Resin 3D Printers, Bendable and not Brittle, 1KG White

Just thought I would leave a review for this resin, after switching to it from a resin with similar purpose but much higher price. The other resin I was using (a roleplaying game resin from a very cold company) was supposed to be very flexible, and durable, and be easy to print with. Unfortunately in my experience none of these were quite true. Since this Sunlu resin was supposed to do the same sort of thing, in the same colour, with very similar density and viscosity properties etc as the other resin I'd tried, I expected a similarly difficult printing experience for a not very useful final product. However, I had heard very good things about this one, so I gave it a try. In short, all of my expectations have been exceeded, and for less than half the price of the previous resin I was using. I cannot recommend this highly enough. This will now be my main resin for all my projects until something else revolutionary comes out.Printer settings for context:Sunlu Toughness resin, mixed 50:50 with Sunlu ABS-like resin12k Elegoo printer0.03mm layer height2.0s exposure time (maybe 2.05, can't remember, but around there)Mini heater maintaining a constant 28°C to ensure temperature is not an issuePrinting 28mm miniatures for tabletop wargamingEase of Printing-----This resin is excellent to print with. So far I've gone through 2kg of this 50:50 ABS-Like/Toughness mix, and have had zero fails. None. No misprinted details either, no layer shifts, nothing. Amazing stuff. I'm churning through army projects and not having to stop to reprint 2 or 3 models per plate, like I was doing with the previous resin (and only that resin - my other resins have close to a 100% success rate too, but this Sunlu one is the only one that has a literal 100% success rate up to now, after 2kg of prints at that). This kind of success rate makes printing fun, because let's face it, the post-processing routine is lengthy and involves chemicals, so I only want to process as few prints as I can get away with. No failed prints means no extra plates to print or process, keeping everything moving, minimising the number of hours I spend suited up in PPE dunking prints in 99% IPA, waiting for them to dry, removing supports in hot water, waiting for them to dry again, curing them, etc. It all takes time, and this resin gives me confidence my time will be well-spent. This also lets me predict my projects' end dates ahead of time too, because I know there will be no (or very few) print failures to have to go back and print again. Very good printing experience.Post-processing experience-----Please take my experience here with a grain of salt as I'm using a 50:50 mix of ABS-like and Toughness, and have never used them separately, so I don't know which resin is contributing which part to my experience here.With that said, my resin mix is quite viscous, which I believe is just how all flexible resins are. However, this does mean that a lot of uncured resin remains stuck on your prints after they've finished, even if you angle the build plate for the resin to drip back into the vat.For that reason, I wash this resin in 99% IPA in 3 stages: 1) get most of the gloopy resin off, 2) get the thin layer of resin underneath off, 3) final 'clean' wash to remove any last sticky bits in crevices.This works really well though, and this resin comes back with a lovely finish when all the IPA has evaporated off.Support removal is fine; again, the flexibility of the resin means the supports are a little more elastic than regular resins, meaning they're a little more grippy, but still easy enough to remove with some hot water. Very little support scarring too, sometimes it's not even visible, which is again great as it means no gap-filling or sanding after the models are cured.I cure it as Sunlu indicate; 5 minutes on my wash & cure turntable. Not in water - it seems fine to do this one without. You can feel the difference once they're cured, which is reassuring.All in all, easy to post-process.Resin properties-----I got the dark grey colour, and of the various resins I've bought, this one is closest to the colour used by well-known plastic miniature manufacturers. It doesn't feel like they've just tried to copy the colour at the expense of other areas either; it's also a really nice finish, nice and matte but with a little sheen in some angles; not too transparent at the edges of details like some other resins; shows off details really really well. Really pleasing to look at - I'm very happy to spend time looking at this resin while building my minis.Again, please remember I'm using a 50:50 mix of Sunlu ABS-Like and Toughness resins, so am not sure which resin contributes which properties here - but it is an incredible resin for tabletop wargaming miniatures. Firstly, even after curing it feels kind of soft in the hand (as opposed to that rough brittle kind of feel other resins tend to have). One review I read of this resin said it's the first resin they've ever handled that feels like an injected thermoplastic, and I agree with them. It's still clearly resin when in your hand but just feels less so, somehow. Very pleasant to handle. I've even heard you can shave bits off this resin with a modelling knife, and drill into it with a pin vice - I've not tried these myself but having handled the resin, I believe both claims.It is also incredibly flexible, and bends rather than breaks. Again please bear in mind I mix with the Toughness resin, which is supposed to be the bendy one, so can't comment purely on ABS-like. However, my experience of the mix is great. Prior to this I used the widely-known Siraya Tech Fast/Tenacious mix - which was nice and strong, but even that would snap after bending a few degrees. With this Sunlu resin, after curing a sword I bent the blade back on itself, and braced myself for a snap, but it didn't snap. It kept going and going until the whole sword blade was folded in half. I then repositioned it back to being a straight blade. Then bent it in half the other way, and back! It finally snapped on the 3rd bend - but it was like the sword tore in two, as opposed to shattered into bits. I'm very very impressed.I've tried dropping a couple minis and they suffered no damage, but since I need them for my project I didn't drop them from too high! So maybe not the best test of durability I could have done.Conclusion-----I've printed with 3 resins this year: 2kg of Siraya Tech Fast/Tenacious, 1kg of Phrozen RPG, and 2kg of Sunlu ABS-Like/Toughness. For my application of tabletop minis, the Sunlu resin blows the other two out of the water. The detail of the prints is excellent on all three, but in every other area the Sunlu pulls ahead: the finish of the resin looks way better than the Phrozen (which can look a bit gritty or chalky imo) and the Siraya Tech (which looks great apart from the heavy white pigment they use to give it its matte look, that ends up sometimes settling in some recesses). The flexibility is better with Sunlu than either other resin. The durability is better with Sunlu than either other resin. My ratio of print successes is literally 100% with the Sunlu, 99% with the Siraya Tech, and nowhere near with the Phrozen. It's incredibly easy to work with too. And reasonable curing times (5 minutes according to Sunlu*), as opposed to the Phrozen for example (which requires 30 minutes according to Phrozen*).*Please check these curing times for yourself, in case they have been updated since this review.Oh, and lastly - I haven't mentioned the price. This resin is cheaper than either other I've used. The Siraya Tech fast/tenacious mix is more expensive than this Sunlu resin, and the Phrozen RPG is more than 2x the cost of this Sunlu resin - and in my experience the Sunlu did a much better job! I don't know how they produce this resin so cheap, but in my opinion price has no impact on quality here.I think the most important thing for me is that this resin gives me confidence that the hours I'm going to spend painting my minis probably won't be wasted due to the resin breaking while I'm holding the minis to paint them, or if I lend them to my friends to play a game of battle mallet together. I was prepared to pay good money for that kind of peace of mind, but it turns out I didn't even have to.All in all, this is now my go-to resin for minis, and will be until something truly game-changing is released. I was sceptical of all the glowing comments and reviews I read online about the Sunlu resin, yet now here I am writing one myself. Very pleased.

Great product

Possibly my new favourite train for printing miniature figure (table top gaming). Resin has a good amount of flexibility (even after curing). I printed in a heated enclosure (air temp was 30’C) - even at that temperature, the resin was a little “gloopy” at the end of prints and needs to scrub in isopropyl alcohol to make then clean. Prior to curing in curing station.I’ve not yet “tested” the survivability of models if dropped.

Used on elegoo Saturn 3 ultra resin colour white.Calibration cones gave a exposure time of 2.4 seconds.No issues experienced with printed models.Excessive exposure to IPA can make the prints less ridged so no more than 1 minute during clean up recommended.Thoroughly dry before curing👍.Made wheels for RC car which I race.No cracks or deformation yet even after some horrific crashes🙈Great value for moneyJust purchased more but in black this time.😁

Excellent resin, seems a lot less brittle than the elegoo abs like I was previously using.

I switched from Sunlu Nilon-Like to this High Toughness resin with an identical 3D model (a box) and identical treatment: 10 minute isopropyl alcohol machine wash, drip dry 10 minutes (all evaporated), followed by 15 minutes of UV curing. Check, then another 15 mins of curing. The part was still tacky after the cure so I put it back for another 20 minutes. Still tacky. Figured it may have dissolved alcohol and needed to dry. Left it for a week and it has become quite warped and still slightly tacky to the touch. It's been 3 weeks now and the part has continued to warp badly.The Nylon like resin was never temperamental like this, no matter how I cured or washed or printed it. Feel sad that I bought 2KG of this stuff.

Not flexible resin has stated but stronger than others.
