SUNLU Resin Review 2025: Is This the Best Budget Resin for High-Detail Prints?

SUNLU Resin Review 2025: Best Value for SLA/DLP Prints?

In the ever-expanding universe of 3D printing, resin (SLA/DLP) printing has set the standard for high-detail, smooth-surface-finish models. From intricate miniatures for tabletop gaming to precise dental molds and engineering prototypes, the capabilities are astonishing. But this high resolution has historically come with a high price tag, not just for the printers, but for the consumable resin itself.

For years, hobbyists and small businesses have faced a difficult choice: pay a premium for “boutique” resins or risk failed prints and frustration with mystery-brand bottles from the depths of the internet.

Enter SUNLU.

Already a dominant force in the FDM world with their popular PLA+ filaments and filament dryers, SUNLU has turned its manufacturing expertise to the world of photopolymer resin. Their goal is simple: to deliver consistent, high-quality, and user-friendly resin at a price that makes 3D printing accessible to everyone.

But does it hold up? Is this the best-value resin for your SLA/DLP printer in 2025? In this comprehensive SUNLU resin review, we’re doing a deep dive into their most popular formulations—Standard, ABS-Like, and Water Washable—to help you decide where to spend your money.

Why Choose SUNLU Resin? The Value Proposition

Before we break down each bottle, let’s talk about why SUNLU has captured so much of the market. It’s not just about being a cheap 3D printer resin; it’s about providing incredible value.

Unbeatable Affordability: The ‘Affordable 3D Printer Resin’ King?

This is SUNLU’s most obvious advantage. A 1000g bottle of SUNLU resin often costs a fraction of what you’d pay for “premium” brands. This is a game-changer for several reasons:

• Learning Without Fear: Beginners can burn through their first bottle just learning how to level the build plate and dial in exposure settings. SUNLU’s low price removes the “fear of failure,” encouraging experimentation.
• Prototyping: Need to print three different versions of a design to check the fit? SUNLU makes it economically viable.
• Large-Scale Prints: When you’re printing a full-size helmet or a large diorama, the cost of resin adds up fast. SUNLU keeps large projects from breaking the bank.

When you combine their base price with a SUNLU coupon, it’s easily one of the most cost-effective resins available.

High Detail and Print Quality

A low price is useless if the prints are bad. Thankfully, SUNLU resins perform exceptionally well. They are formulated for 405nm mSLA printers (which includes 99% of hobbyist printers from Elegoo, Anycubic, Creality, and Phrozen) and are capable of resolving incredibly fine details. We’ve found that text, sharp edges, and delicate textures on miniatures are captured crisply with minimal light bleed.

Low Odor and User-Friendly Formulations

One of the biggest complaints about resin printing is the smell. While no resin is truly “odorless,” SUNLU has clearly invested in formulations that produce significantly fewer volatile organic compounds (VOCs) and have a much milder, less offensive smell than many competitors. This makes printing in a home office or workshop far more pleasant.

Wide Compatibility and Consistency

SUNLU resin works well with the entire spectrum of LCD printers, from older 2K monochrome screens to the latest 8K and 12K high-resolution machines. Their large-scale manufacturing ensures high consistency between batches. The bottle you buy today will have the same properties as the one you buy six months from now, which is critical for reliable printing.

The SUNLU Resin Lineup: A Detailed Review

SUNLU’s official store offers a growing range of resins, but most users will be interested in their “big three.” We put them to the test.

SUNLU Standard Resin: The All-Rounder for Daily Prints

This is the workhorse of the SUNLU lineup. It’s a rigid, somewhat brittle resin designed for general-purpose printing where high detail is the primary goal.

• Best For: Display models, miniatures, busts, and prototypes where functional strength is not the main priority.
• Printability: This resin has a medium-low viscosity, making it easy to work with. It flows well, settles quickly between layers, and is less prone to “cupping” issues on hollow models. We found it extremely easy to dial in.
• Post-Processing: It cleans up perfectly with a 2-3 minute bath in 95%+ Isopropyl Alcohol (IPA). It cures quickly under a UV lamp (around 3-5 minutes), resulting in a hard, matte surface.
• Pros:
  • Extremely affordable.
  • Excellent detail and sharpness.
  • Very low odor for a standard resin.
  • Fast curing times.
• Cons:
  • Brittle. Thin parts will snap rather than bend. Not recommended for parts that will be dropped or handled roughly.

Verdict: For anyone printing models that will sit on a shelf, SUNLU Standard resin is a no-brainer. The quality-to-price ratio is outstanding.

A Deep Dive: SUNLU ABS-Like Resin Review

This is where things get interesting. The “ABS-Like” formulation is designed to mimic the properties of ABS filament—specifically, its toughness and impact resistance. This addresses the number one complaint about standard resin: brittleness.

• Best For: Functional parts, mechanical prototypes, articulated figures, tabletop miniatures that will actually be used in a game, and anything that might be dropped.
• Printability: This SUNLU ABS-like resin is slightly more viscous (thicker) than the Standard resin. This is normal for “tough” resins. It just means you might need to add a slightly longer “light-off delay” in your slicer settings (e.g., 1 second) to allow it to settle.
• Post-Processing & Performance: It cleans in IPA just like standard resin. After curing, the difference is night and day. Parts are significantly more durable. Thin pieces have a noticeable flex, and the cured resin can withstand impacts (like being dropped on a hardwood floor) that would shatter a standard resin print.
• Pros:
  • Excellent toughness and durability.
  • Still captures fantastic detail.
  • Gives prints a functional, professional feel.
  • Greatly expands the applications of your resin printer.
• Cons:
  • Slightly more expensive than Standard resin.
  • May require slightly longer exposure times.

Verdict: The SUNLU ABS-like resin review is overwhelmingly positive. For a small increase in price, you get a massive upgrade in durability. This is our pick for the best SUNLU resin for general-purpose use.

SUNLU Water Washable Resin: Is the Convenience Worth It?

The mess and smell of Isopropyl Alcohol are major turn-offs for many users. SUNLU water washable resin is the solution. As the name implies, you can clean your prints using only tap water.

• Best For: Beginners, users in small apartments, or anyone who wants to simplify their workflow and avoid flammable, smelly chemicals.
• Printability: We found this resin to be just as easy to print with as the Standard formulation. Detail is sharp, and it adheres well to the build plate.
• Post-Processing: This is its superpower. Simply rinse your print in a container of water (or an ultrasonic cleaner with water) for a few minutes. Important Note: Do NOT rinse it in your sink. The water will be contaminated with uncured resin particles, which are not sewer-safe. Cure the contaminated water in the sun to solidify the resin particles, then filter them out and dispose of the solid waste.
• Performance: Once cured, water washable resin tends to be even more brittle than Standard resin. It’s also slightly hygroscopic (it can absorb moisture), so it’s not ideal for parts that will be used in humid environments.
• Pros:
  • Incredibly easy and cheap cleanup—no IPA required!
  • Very low odor.
  • Great for users with sensitivities to chemicals.
• Cons:
  • Cured parts are brittle.
  • Improperly cured prints can be prone to cracking over time.

Verdict: If your primary concern is convenience and avoiding IPA, this resin is a fantastic choice. Just be aware of its brittle nature and don’t use it for functional parts. Don’t forget to grab a SUNLU resin coupon code to make this convenient option even cheaper.

Getting the Best Results: SUNLU Resin Settings and Curing

A great resin is only half the battle. You need the right settings. While the official SUNLU website provides recommended settings for popular printers, here is our universal guide to dialing in your SUNLU resin settings.

Dialing in Your Exposure Settings

1. Start with a Calibration Test: Don’t just guess and start a 10-hour print. Use a calibration model like the “Cones of Calibration” or the “AmeraLabs Town.” These print in under 20 minutes and help you find the perfect exposure time for your specific printer and resin.
2. Monochrome vs. RGB Screens: If you have a modern printer with a monochrome (mono) screen, your exposure times will be very fast, likely between 1.8 and 3.5 seconds. If you have an older printer with an RGB screen, your times will be much longer, from 6 to 12 seconds.
3. Bottom Layers: Start with 4-6 bottom layers at around 20-30 seconds each. This ensures a strong-as-concrete adhesion to your build plate, preventing prints from failing halfway.

A good starting point for SUNLU ABS-Like Resin on a typical 8K mono-screen printer is:

• Layer Height: 0.05mm
• Bottom Exposure: 25 seconds
• Normal Exposure: 2.8 seconds
• Light-Off Delay: 1 second

Adjust your Normal Exposure up or down by 0.2 seconds based on your calibration test.

Post-Processing: Washing and Curing

• Wash: For Standard and ABS-Like, use a “dirty” bath of IPA first to get the worst off, followed by a “clean” bath to finish. For Water Washable, use the same two-bath method, but with water.
• Dry: This is critical! Ensure your print is completely dry before curing. Use a compressed air can to blow IPA or water out of crevices. If you cure a wet print, it will get a white, chalky residue.
• Cure: A dedicated UV curing station is one of the best investments you can make. It provides consistent, 360-degree UV light. If you don’t have one, a simple UV nail lamp or even direct sunlight will work, but you’ll need to manually rotate the part to ensure all sides are cured.

How Does SUNLU Resin Compare? (SUNLU vs. Elegoo)

This is the big question for most budget-conscious buyers. SUNLU resin vs Elegoo resin—which is better?

Honestly, both brands are fantastic and represent the “gold standard” of affordable resin. Elegoo’s Standard and ABS-Like resins are famous for a reason. However, in our 2025 testing, we found a few subtle differences:

• Odor: We consistently found the SUNLU formulations to have a noticeably milder, less “chemical” smell than their Elegoo counterparts.
• Price: The price fluctuates daily. Sometimes Elegoo is cheaper, sometimes SUNLU is. This is why it’s essential to check a deals page like Prodynest before you buy.
• Toughness: We found Elegoo’s ABS-Like to be slightly more flexible, while SUNLU’s ABS-Like felt a bit harder and more rigid, truly living up to the “ABS” name. Both are vast improvements over standard resin.

Verdict: You cannot go wrong with either. Our advice is to buy whichever is on sale. More often than not, SUNLU’s Amazon deals or our exclusive coupons give it the edge.
