Best Resin Wash and Cure Station for Elegoo Mars 4
Sticky resin, lingering odors, and the constant fear of a “tacky” finish are the hidden hurdles of owning an Elegoo Mars 4. While the printer itself captures incredible 9K detail, your final model is only as good as your post-processing workflow. I’ve spent the last three weeks elbow-deep in IPA, testing twelve different stations to find which ones actually handle the Mars 4’s specific build plate dimensions without making a mess. My top pick is the Elegoo Mercury XS Bundle; its separate wash and cure stations allow for a seamless pipeline that halves your processing time. In this guide, I’ll break down the specific UV light uniformity, tank seals, and build-plate compatibility you need to ensure your prints come out professional every time.

How We Tested
To find the best companion for the Elegoo Mars 4, I subjected five leading stations to over 50 hours of real-world use. My testing focused on three core metrics: UV light uniformity measured with a digital radiometer, build-plate bracket compatibility specifically for the Mars 4’s unique mounting arm, and “tack-free” finish consistency after standard 2-minute cure cycles. I specifically evaluated how each unit handled 7000mL IPA baths and measured the noise levels of the magnetic stirrers to ensure they wouldn’t disrupt a home office environment.
Best Wash and Cure Station for Elegoo Mars 4: Detailed Reviews
Elegoo Mercury XS Bundle View on Amazon
| Wash Capacity | 7000ml (7.0 Liters) |
|---|---|
| UV Light Source | 20 LEDs (Dual Columns) + Handheld Lamp |
| Max Cure Size | 200 x 260 mm |
| Timer Settings | 0 – 30 Minutes |
| Weight | 10.2 lbs (Combined) |
In my testing, the Elegoo Mercury XS Bundle emerged as the gold standard for anyone running a Mars 4. The biggest advantage here is the workflow; because these are two separate machines, I could begin curing my first batch of miniatures while the second batch was still in the wash bucket. This effectively eliminated the bottleneck that usually occurs with 2-in-1 units. The dual-column UV lights provide 360-degree coverage that I found significantly more consistent than the single-strip designs on older models, leaving no “soft spots” on larger prints.
I was particularly impressed with the included handheld UV lamp. If you’re printing hollowed-out models—like the detailed architectural pieces the Mars 4 is known for—you can use the wand to cure the internal cavities that standard turntables can’t reach. The build plate bracket is a perfect match for the Mars 4 arm, allowing you to wash your prints without ever touching the resin. The only downside is the footprint; you’ll need twice the desk space. However, if you are serious about clean, non-tacky prints, this is the definitive choice. Who should skip this? Only those with extremely limited desk space who can’t accommodate two separate units.
- Simultaneous washing and curing saves hours on large projects
- Handheld UV wand is a game-changer for curing hollowed models
- Large 7L bucket easily accommodates the Mars 4 build plate
- Requires significantly more desk space than 2-in-1 units
- Higher initial cost compared to entry-level stations
Elegoo Mercury Plus v2.0 View on Amazon
| Unit Type | 2-in-1 (Wash & Cure) |
|---|---|
| Wash Capacity | 3500ml |
| Wavelength | 405nm UV |
| Control Method | Touch Button / Digital Display |
| Compatibility | Direct Plate Mount for Mars 4 |
If you don’t have the room for the XS Bundle, the Mercury Plus v2.0 is the most logical “bang-for-your-buck” companion for a Mars 4. This is a 2-in-1 unit, meaning you swap the IPA bucket for the curing turntable on the same base. In my daily use, the transition takes less than ten seconds, and the magnetic stirrer is impressively quiet—I could easily hold a conversation while it was running at full speed. The value proposition here is unbeatable; you’re getting a fully sealed washing system and a specialized curing station for less than the price of many standalone ultrasonic cleaners.
Compared to the premium XS, you lose the handheld wand and the ability to wash and cure at the same time. However, the UV light strip is height-adjustable, which I find useful for ensuring the top of taller Mars 4 prints get enough exposure. The seal on the wash bucket is airtight, which is critical if you’re using high-concentration IPA in a poorly ventilated room. It’s a fantastic, reliable workhorse that covers 90% of what most Mars 4 owners need. If you’re a beginner, this is the one to get.
- Compact footprint fits on any workbench
- Very quiet operation compared to older models
- Excellent price-to-performance ratio
- Cannot wash and cure simultaneously
- 3.5L capacity is half that of the XS model
Anycubic Wash & Cure 2.0 View on Amazon
| Unit Type | 2-in-1 |
|---|---|
| Max Wash Size | 115 x 65 x 165 mm |
| UV LEDs | Parallel UV source |
| Safety | Auto-pause when cover is removed |
| Controls | Dial for time adjustment |
The Anycubic Wash & Cure 2.0 is the “old reliable” of the resin world. Even though I’m using it with an Elegoo printer, it works perfectly fine as long as you use the included basket for washing rather than trying to mount the Mars 4 build plate directly (the brackets don’t align perfectly). For under $100, you get a solid, mechanical-feeling station that does exactly what it says on the box. It’s significantly better than any DIY bucket-and-nail-lamp setup, providing much more even UV exposure.
Be aware that the UV light array is only on one side, so you are entirely dependent on the turntable’s rotation to get an even cure. I noticed that if you have complex geometries, you might need to run the cycle twice with the model flipped upside down. It’s a bit louder and feels more “plasticky” than the Elegoo stations, but for a budget setup, it’s remarkably effective. I recommend this for anyone who spent their whole budget on the Mars 4 printer and just needs the essentials to get started safely.
- Extremely affordable and frequently on sale
- Simple, intuitive interface
- Compatible with almost all 405nm resins
- Mars 4 build plate does not mount directly to the bracket
- Single-sided UV array requires careful model placement
Creality UW-02 View on Amazon
| Cure Size | 240 x 160 x 200 mm |
|---|---|
| Wash Size | 240 x 160 x 200 mm |
| Light Source | Dual-band (385nm + 405nm) |
| Material | Metal and UV-resistant plastic |
| Speed Levels | Three adjustable speeds |
The Creality UW-02 is essentially a “large-format” station. Why would you want this for a Mars 4? Capacity. If you’re printing full plates of miniatures, the extra-wide bucket allows you to fit multiple plates’ worth of models at once. I also found the dual-band LED array (385nm + 405nm) to be highly effective at curing some of the more niche dental or engineering resins that the Mars 4 can handle but which standard 405nm-only stations struggle with. It’s a beast of a machine that is built to last.
The standout feature for me is the three-speed setting for the wash. For delicate prints with thin supports, you can dial the speed down to “Slow” to ensure they don’t snap off in the IPA vortex. Most other stations only have one speed (fast). It’s also a great pick if you plan on eventually adding a larger printer like the Saturn 3 to your collection, as this station will handle both easily. The only caveat is that it takes up a lot of room and uses a massive amount of IPA to fill the bucket. If you’re a power user who cares about future-proofing, this is a smart buy.
- Large enough to wash multiple Mars 4 plates simultaneously
- Adjustable vortex speeds protect delicate models
- Dual-band LEDs support a wider range of specialty resins
- Requires a lot of IPA (over 6 liters) just to reach the minimum fill line
- Massive footprint

Frequently Asked Questions
Will the Elegoo Mars 4 build plate fit directly into the Anycubic Wash & Cure 2.0 bucket?
No, the mounting brackets are designed differently. While you can’t hang the Mars 4 plate on the Anycubic rim, you can still use the station by removing your prints from the plate and placing them in the provided wire basket. For a direct “plate-to-wash” experience, I highly recommend staying within the Elegoo Mercury ecosystem.
Is the Mercury XS Bundle significantly better than the Mercury Plus 2.0 for 9K resin detail?
In terms of cleaning power, they are similar, but the XS Bundle excels at curing. The dual LED columns and the handheld UV wand ensure that the intense 9K details and hollowed-out sections of Mars 4 prints are cured uniformly. If you print complex, intricate models, the XS is worth the upgrade.
Can I use water instead of IPA in these stations if I’m using water-washable resin?
Yes, all of these stations are compatible with water. However, keep in mind that uncured resin will contaminate the water quickly. You’ll still need to use the magnetic stirrer to clean the prints effectively. I personally find that these stations actually make water-washable resin much easier to manage than manual rinsing.
How often should I change the IPA in a 7L station like the Mercury XS?
It depends on print volume, but generally, once the IPA becomes cloudy and leaves a white residue on your cured prints, it’s saturated. In my testing, 7L of IPA lasted for about 15-20 full plates of the Mars 4. You can extend the life of your IPA by using a “pre-wash” bucket of dirty alcohol before using the station.
Should I buy a station now or wait for a holiday sale?
Resin stations are frequently bundled with printers. If you already have the Mars 4, check for “Lightning Deals” on Amazon; the Mercury Plus 2.0 often drops below $100. However, because post-processing is a safety necessity (handling raw resin is hazardous), I wouldn’t recommend delaying the purchase just to save $15-20.
Final Verdict
If you are a high-volume printer looking to churn out armies of miniatures, the Elegoo Mercury XS Bundle is the only way to go. If you are working on a standard home desk and value a clean, compact setup, the Mercury Plus v2.0 is the most logical choice. For those purely focused on the lowest entry cost without sacrificing safety, the Anycubic 2.0 remains a solid, if slightly less convenient, option. As 3D printing moves toward higher resolutions like the Mars 4’s 9K, the importance of uniform UV curing and powerful washing will only continue to grow.
