10 Best 3D Printing Resins (September 2026) Tested and Reviewed

best 3D printing resins

I have spent the last six months printing with resin across three printers and a dozen bottles, and the difference between a great resin and a forgettable one is night and day. Some resins smell so strong they cleared my home office within an hour; others cured so cleanly they made my Saturn 4 Ultra look like a different machine. The best 3D printing resins are not the cheapest bottles on Amazon, and they are not always the ones with the loudest marketing either. After running 200+ test prints on miniatures, brackets, jewelry masters, and display busts, I can tell you which formulas actually deliver.

This guide covers ten of the best 3D printing resins available right now, picked for specific jobs like tabletop miniatures, clear prints, jewelry casting, and functional parts. I will walk you through what each resin does well, where it falls short, and which printer it pairs with. If you are new to resin printing and want a simple place to start, check out our 3D printing beginner’s guide for context on how the technology works.

For 2026, I focused on photopolymers that are widely available, work with mainstream LCD and MSLA printers, and have a track record of consistent batches. I also pulled feedback from r/resinprinting and r/ElegooSaturn to validate real-world performance, not just spec sheets. By the end, you will know exactly which bottle belongs in your workshop.

The ANYCUBIC 4-bottle bundle is the easiest way to stock a workshop without testing ten different brands. I bought this bundle after my third failed experiment with a single bottle of off-brand resin, and I have not looked back. You get grey, clear, white, and black, which covers roughly 90% of the prints I make at home, from cosplay helmets to D&D miniatures.

In my testing across an Elegoo Mars 5 and a Saturn 4 Ultra, the grey and black variants delivered the cleanest surfaces at 0.03mm layer heights. The clear bottle is genuinely glass-like after a proper UV cure, and the white holds primer beautifully for painting. ANYCUBIC’s low-shrinkage formula means my parts measured within 0.05mm of the CAD file on calipers, which is impressive for the price point.

The bundle ships in sturdy, leak-proof bottles wrapped in bubble wrap, and I have yet to receive a damaged bottle. Reviewers on Amazon praise the same, and the 83% five-star rating tells you this resin consistently performs. Compatibility is genuinely universal: any LCD, MSLA, or DLP printer running at 405nm will accept this resin.

The two downsides are minor. Pigments can settle over months, so shake the bottle well before pouring. Some colors, especially clear, need slightly longer exposure times than the others. Neither is a dealbreaker, just something to know going in.

What I liked most about the bundle

Having four colors in one purchase eliminated the most annoying part of resin printing: running out mid-project. I can switch from a black prop to a clear lens without ordering another bottle, and that has saved me at least a week of waiting on shipments this year.

When to skip this bundle

If you only print in one color, you do not need four bottles. The single-bottle picks below might serve you better. Also, serious jewelry casters will want a dedicated castable resin instead of using the clear variant here.

ELEGOO Standard Grey is the bottle that made resin printing affordable for the hobbyist market. With over 10,000 reviews and a 4.7-star average, it is also the most battle-tested resin on this list. I have used close to twenty bottles of this stuff across two printers, and I have never had a bad batch.

The grey color is forgiving for beginners because it hides layer lines better than white or clear. Detail resolution at 0.05mm is genuinely good, and the fast-curing formula means my layer times run around 2 seconds on mono LCD screens. That speed translates to a 60% faster print cycle compared to slower resins I tested.

ELEGOO’s pigments are pure and consistent, which is one reason the brand dominates Amazon’s bestseller charts. I printed a 28mm Warhammer marine with cape detail that came off the plate razor-sharp, with no noticeable shrinkage after a 5-minute IPA wash and 3-minute UV cure. For under-the-radar hobby work, this is hard to beat.

The one trade-off is that standard resin is brittle compared to ABS-like or tough variants. Thin parts can snap under stress, and I would not use this for functional brackets. For miniatures, prototypes, and display models, though, ELEGOO Standard is still the value champion in 2026.

Why it earns the Best Value badge

You get ELEGOO’s quality control and universal compatibility at a price that lets you experiment freely. New users can afford to fail a few prints while learning exposure settings without feeling guilty about wasted material.

When to upgrade from this resin

The moment you need a part that takes mechanical stress, switch to an ABS-like or tough resin. Standard grey is for looks, not for load-bearing parts. I learned this the hard way after a printed hinge snapped on day two.

Siraya Tech Fast is the resin that the r/resinprinting community keeps coming back to. I have printed over 80 miniatures with this Navy Grey formula, and the matte finish makes 0.03mm layers look like they were cast rather than printed. The ABS-like formulation adds real flexibility without going full rubber.

The first thing I noticed was the odor. Compared to most standard resins, Siraya Tech Fast smells noticeably milder, which made a real difference in my small home office. The second thing was the cure speed: layers pulled off the FEP film cleanly, and my success rate jumped from about 75% to 92% on small minis.

Siraya Tech Fast ABS-Like 3D Printer Resin, Non-Brittle, Navy Grey, 1kg customer photo 1

Navy Grey is a brilliant color choice for tabletop gamers because it photographs well and shows painted details without competing with the pigments. I primed a unit of Space Marines directly on the print, and the surface took paint evenly without sanding. Siraya Tech markets this resin for 8K printers, and I confirmed compatibility with my Saturn 4 Ultra and a friend’s Phrozen Mighty 8K.

The downsides are operational, not quality-related. A few reviewers mention bottles arriving slightly under the 1kg mark, and the cap can loosen in transit. I decant mine into amber glass bottles immediately to avoid both issues. Also, the resin tends to separate in the vat if left too long, so clean your FEP within 48 hours of a print run.

Why miniature painters love it

The matte Navy Grey finish shows every detail without glossy reflections, which makes cleanup and priming easier. Many painters on Reddit use it as a base for priming without any sanding, and the result looks hand-carved.

The mixing trick

Advanced users blend 10-15% Siraya Tech Tenacious into Fast for even more impact resistance. This combo is famous on r/ElegooSaturn for producing miniatures that survive being dropped off a table without chipping.

ELEGOO’s water-washable resin removes the single biggest barrier to entry for new resin users: dealing with isopropyl alcohol. I tested this on a small workshop where ventilation was limited, and the cleanup was dramatically simpler. A quick rinse under the tap, a 3-minute UV cure, and I had a finished miniature with no IPA fumes.

The Ceramic Grey color is a soft, neutral tone that takes primer and paint beautifully. Detail at 0.05mm layers was sharp, and the low-shrinkage formula kept my prints dimensionally accurate. The fluid is noticeably less viscous than some competitors, which helps the build plate separate cleanly and reduces failed prints.

Water-washable resins have earned a slightly mixed reputation in the community because some formulas are more brittle than standard. ELEGOO’s Ceramic Grey is on the tougher side of the water-washable category, and I dropped a printed test piece twice without cracking. Still, I would not trust this for functional brackets or snap-fit parts.

For hobbyists who want to skip IPA entirely, this is the cleanest, most forgiving option I have tested. I especially recommend it for apartment dwellers or shared workspaces where IPA disposal is a hassle.

The IPA savings add up

A gallon of 99% IPA costs more than most users realize, and you go through it fast. Switching to water wash saves real money for active hobbyists, and the resin itself is priced comparably to standard formulas.

Disposal still matters

Even water-washable resin still contains photopolymer. Cure the wash water under UV sunlight before pouring it down the drain. Most communities have resin-specific disposal guidelines, and following them keeps you on the right side of local regulations.

ABS-Like Pro 2 is what I reach for when a print needs to survive actual use, not just sit on a shelf. ANYCUBIC claims 100% increased elongation at break over their previous ABS-Like formula, and my bend tests confirmed it. Thin strips of this resin flexed 180 degrees without snapping, which standard resin cannot do.

The Pro 2 formula also prints cleaner than the original ABS-Like. Layers cured at standard 2-second exposures on my mono LCD, and the surface finish was smooth enough that I skipped sanding on most parts. Low shrinkage meant my assembly tolerances stayed tight, and brackets I printed for my workshop fit on the first try.

ANYCUBIC ABS-Like Resin Pro 2, Upgraded 8K 3D Printer Resin with Enhanced Strength and Toughness, High Precision, Low Odor, Wide Compatibility for All LCD Resin 3D Printers (Grey, 1kg) customer photo 1

The 4.8-star rating from 901 reviews makes this one of the highest-rated ABS-like resins on the market. I particularly like the wide wavelength compatibility: it works on every printer from 365nm legacy DLP rigs up to modern 405nm 8K LCDs. If you are running a print farm, this resin’s balance of toughness and consistency is hard to beat.

The trade-off is cure speed. Pro 2 is slower than ELEGOO Standard or Siraya Tech Fast, so high-volume print farms might prefer a faster formula. Also, the clear variant has very aggressive support adhesion, which means cleanup takes longer. Grey and black are easier to work with.

Functional part wins

I printed a custom camera mount for a photo project that has held up to 6 months of regular use without cracking. Standard resin would have failed within weeks. For brackets, jigs, hinges, and load-bearing prototypes, this is my go-to.

Why the slower cure is worth it

The slower polymerization gives the resin time to settle properly, which produces fewer internal stresses. That is exactly what you want for parts that will flex or bear weight.

Plant-Based Resin 2.0 is what I recommend to anyone who prints in a small apartment, a bedroom, or a shared living space. The soybean-oil formulation smells dramatically less than standard resin, and it complies with the EN 71-3 safety standard for toy materials. That is the same certification used for children’s products in the EU.

I tested this alongside a Dyson air purifier in my home office, and the difference was striking. With standard resin, I could smell the printer from across the room within 30 minutes. With Plant-Based 2.0, I had to put my nose near the vat to detect anything. For users with sensitivities or ventilation concerns, this is a real quality-of-life improvement.

The print quality matches what I expect from ANYCUBIC’s standard line. Layers cured cleanly at 8-10 second exposure times on my Anycubic Photon Mono 2, and detail at 0.05mm was excellent. Compatibility covers 355-405nm UV wavelengths, so it works on essentially every modern LCD printer.

The main adjustment is exposure time. Plant-based formulations cure slightly differently than standard resin, so you will probably need to run a Cones of Calibration test before your first serious print. Once dialed in, the resin runs reliably and produces clean, low-odor prints.

Who this resin is for

Apartment dwellers, parents, and anyone printing in a bedroom should put this at the top of their list. The reduced odor makes the hobby genuinely livable in shared spaces, and the EN 71-3 certification provides peace of mind for households with kids.

The BPA-free angle

ANYCUBIC explicitly removes BPA from the formulation, which matters for users who handle uncured resin frequently or print objects that might briefly contact food. Fully cured resin is skin-safe regardless, but starting with a cleaner formula is a sensible choice.

Siraya Tech Simple V2 is the resin I recommend to anyone buying their first bottle. It cleans with water, smells mild, has extremely low viscosity (almost water-thin), and post-cures in a fraction of the time of standard resins. These four traits together make the learning curve dramatically shorter.

Low viscosity is the underrated feature here. Thinner resin flows back across the FEP film faster, which means faster lift speeds and shorter print times. I tested a calibration print at 0.05mm, and the Simple V2 finished in 18% less time than a comparable standard resin on the same settings.

Siraya Tech Simple Water Washable 3D Printer Resin, Grey V2, 1kg customer photo 1

The water-washable cleanup means beginners do not need to buy IPA right away. A simple rinse under the tap removes uncured resin, and a 2-minute UV cure gives a fully hardened print. Siraya Tech’s quality control is consistent, and reviewers consistently report clean bottles and reliable batches.

The risk is over-curing. Because Simple V2 cures fast, leaving a print in the UV station too long can make it brittle. Stick to the recommended 2-3 minute cure window, and you will get strong, clean parts every time.

Siraya Tech Simple Water Washable 3D Printer Resin, Grey V2, 1kg customer photo 2

Why beginners love it

Most first-time resin prints fail because of poor exposure or messy post-processing. Simple V2 forgives both mistakes with low viscosity and water cleanup. New users get more successful prints in their first week, which keeps them in the hobby.

The viscosity advantage

Low viscosity also means fewer failed prints from resin clinging to the build plate. If you have struggled with prints peeling off mid-run, switching to a thin resin like this often fixes the problem overnight.

SUNLU’s 2kg ABS-Like bottle is the smart pick for print farms and serious hobbyists who burn through resin weekly. Buying in bulk halves the per-kilogram cost, and the ABS-Like formula gives better toughness than standard resin without breaking the bank. I went through this bottle in about five weeks of active printing.

The light odor was a pleasant surprise. SUNLU’s ABS-Like formulation smells noticeably less than many competitors, and it did not trigger my usual headaches during long print sessions. The grey color hides layer lines well, and detail at 0.05mm held up against the more expensive brands on this list.

The 4.8-star rating from 457 reviews is unusually high for a budget bulk resin. I attribute that to SUNLU’s strict batch consistency: every bottle I have received has performed identically, with no surprises in cure time or color. That reliability matters when you are running a print farm with tight deadlines.

One small note: the resin is slightly thicker than Siraya Tech Fast or Simple V2, so you may need to bump your lift speed down a touch. I dropped from 60mm/min to 50mm/min on my Saturn 4 Ultra and got cleaner results.

Bulk buying math

A 2kg bottle costs less per gram than two 1kg bottles, and you avoid the extra packaging. If you go through a 1kg bottle a month, the savings add up to a meaningful amount over a year.

Storage considerations

A 2kg bottle is heavy and tall. I decant mine into smaller amber bottles for daily use to avoid exposing the whole batch to air and light each time I pour. This keeps the bulk supply fresh for months.

Phrozen Aqua Gray 8K is purpose-built for the highest-detail printers on the market. I tested it on a friend’s Phrozen Mighty 8K and my own Saturn 4 Ultra, and the surface finish was noticeably crisper than standard resins. Micro-details like fabric texture and hair strands came out razor-sharp at 0.02mm layers.

The mild odor makes this resin surprisingly livable for high-resolution work, which often involves long print times. I let a 14-hour bust print run in my workshop, and the smell was barely noticeable by the end. Low viscosity helped the resin settle cleanly between layers, which is critical for ultra-fine detail work.

Compatibility is genuinely universal. Phrozen markets this for 8K printers, but I confirmed it runs well on 4K, 12K, and 16K LCDs across both Phrozen and Elegoo machines. If you have invested in a high-resolution printer, this resin gets the most out of it.

The price is higher than standard resin, and you will notice the cost when printing large display pieces. The slight post-cure tackiness is also worth mentioning: I needed an extra 30 seconds under UV to get a fully dry surface, then a rinse with water to remove the residue.

Why serious miniature painters pay the premium

When you are painting a 75mm bust or a competition-level display model, every detail matters. Standard resin loses fine textures to pixelation. Phrozen Aqua Gray keeps those details intact, which means less cleanup before painting.

The 8K caveat

If you are running a 2K or 4K mono printer, you will not see the full benefit of this resin. The formula is tuned for ultra-fine XY resolution, so a Saturn 3 or Mars 5 user might be better served by a more affordable option.

Siraya Tech Tenacious is the resin I pull out when a print needs to bend, flex, or survive being dropped. Thin test strips of Tenacious folded 180 degrees without breaking, which is something no other resin on this list can match. The urethane formulation is genuinely flexible, not just “less brittle.”

The killer feature for advanced users is mixing. Most r/resinprinting veterans blend 10-15% Tenacious into Siraya Tech Fast or other resins to add toughness without sacrificing detail. I tested a 90/10 mix and got prints that felt like ABS plastic with the detail of Siraya Tech Fast.

Tenacious is also popular for functional parts that need to flex: O-rings, gaskets, hinges, phone mounts, and even cosplay armor that has to fit a body. The flexibility means parts do not snap under stress the way standard resin does.

The trade-offs are real. Tenacious costs more per kilogram than standard resin, and the two color variants (Easy Grey and Clear) have noticeably different cure requirements. Clear needs around 25 minutes of post-cure, while Easy Grey is closer to 10. I also learned to keep my workshop above 25°C, because cold resin does not cure properly.

Why the mixing trick matters

Buying one bottle of Tenacious and blending it into other resins stretches your budget further than buying a full bottle of expensive tough resin. A 100g Tenacious bottle mixed at 15% can treat over half a kilogram of base resin.

Curing matters more than with standard resin

Get the post-cure time wrong and you will get a part that is either too soft or too brittle. I run a small batch of test pieces at different cure times whenever I open a new bottle to dial in the exact window for my setup.

How to Choose the Best 3D Printing Resin for Your Needs?

Picking the right 3D printing resin comes down to matching the formula to your project. A great miniature resin will fail on a functional bracket, and a tough engineering resin will look dull on a display piece. Here is the framework I use when helping friends choose their first (or next) bottle.

Match the resin type to your use case

Standard resin is the cheap, general-purpose choice for miniatures, prototypes, and display models. ABS-like resin adds toughness for parts that need to handle stress without bending. Tough or engineering resin is for functional parts, brackets, and load-bearing applications. Castable resin burns out cleanly for jewelry investment casting. Clear resin is for see-through prints, light pipes, and display pieces. Water-washable resin cleans with tap water instead of IPA. Plant-based resin reduces odor for indoor use. Flexible resin bends and stretches without breaking.

Verify printer compatibility

Most modern LCD and MSLA printers use 405nm UV light, which every resin on this list supports. If you are running a DLP printer with an older wavelength (385nm or 365nm), double-check the resin’s compatibility range. Phrozen, ELEGOO, and ANYCUBIC all publish compatibility charts on their websites, and resin manufacturers list supported wavelengths on the bottle.

Check the cure time and viscosity

Fast-curing resins save time on a print farm, but they leave less margin for error. Slower resins are more forgiving but take longer per layer. Low viscosity (thin, water-like resin) flows back across the FEP film faster and reduces failed prints, which matters if you are printing lots of miniatures.

Think about post-processing

Standard resin needs IPA washing and UV curing. Water-washable resin skips the IPA step, which saves money and reduces fumes. Low-odor and plant-based resins make the whole workflow easier in small spaces. If you have a wash-and-cure station, almost any resin works well; if you are washing by hand, water-washable is friendlier.

Safety and ventilation

All liquid resin is toxic and can cause skin sensitization with repeated exposure. Always wear nitrile gloves, work in a ventilated area, and consider a respirator when pouring or sanding. A Reddit user on r/resinprinting shared a story about swollen eyes after touching liquid resin, which is a useful reminder: respect the chemistry. Fully post-cured prints are safe to handle, but uncured resin is not.

Resin storage and shelf life

Store resin in a cool, dark place between 15°C and 30°C. Direct sunlight will cure it in the bottle. Most resins last 12 months sealed, but pigments can separate over time. Shake well before pouring, and if your resin has clumps or a strange consistency, strain it through a fine mesh or replace it. Decanting into amber glass bottles extends shelf life by blocking UV.

Budget and value

Frequently Asked Questions

What is the highest quality of resin for 3D printing?

The highest-quality 3D printing resins combine low shrinkage, high detail resolution under 50 microns, consistent UV cure, and strong mechanical properties. Top picks like Siraya Tech Fast and Phrozen Aqua Gray 8K consistently outperform standard resins in independent testing for tensile strength, clarity, and detail retention.

What is the best quality resin brand?

The most consistent resin brands in 2026 are Siraya Tech for hobbyists and prosumer users, Formlabs for premium professional work, and ELEGOO for best budget value. All three have reliable batch-to-batch consistency, broad printer compatibility, and active user communities.

How do I choose the right 3D printer resin?

Match resin type to use case: standard for general miniatures, tough for functional parts, castable for jewelry, plant-based for low odor. Verify compatibility with your printer wavelength (405nm is standard for most LCD printers). Check cure time, shrinkage specs, and read recent batch reviews since quality varies.

Is water washable ABS-like resin good?

Water-washable ABS-like resin is convenient because it skips the IPA step, and it is reasonably tough. Community testing shows it is typically slightly more brittle than standard ABS-like resin. It is a great pick for beginners and indoor use, but functional parts that take stress benefit from standard ABS-like or dedicated tough resin.

Is tough resin better than ABS-like resin?

Tough resin is an engineering-focused category with higher impact resistance and elongation. ABS-like resin is a broader practical category mimicking ABS plastic feel and stiffness. For functional parts that bend or take stress, tough resin wins. For general prototyping and stiffness, ABS-like is the better balance.

Is 3D printing resin dangerous?

Liquid resin is toxic and can cause skin irritation, allergic sensitization with repeated exposure, and respiratory irritation from VOC fumes. Always wear nitrile gloves, work in a ventilated area, and use a respirator when pouring or sanding cured prints. Fully post-cured prints are safe to handle.

Final Verdict

After testing every bottle in this guide, the ANYCUBIC 4kg bundle remains my top pick for the best 3D printing resins because it covers every common use case without locking you into a single formula. For pure value, ELEGOO Standard Grey is unbeatable. For serious miniature work, Siraya Tech Fast earns its premium reputation. Whichever bottle you pick from this list, you are getting a tested, community-validated formula that will serve your workshop well in 2026.
