Next, Phrozen is yet another large manufacturer of resin 3D printers and supplies, and they are actually one of the leading companies behind 8K-quality printing. As such, it makes sense that they also make one of the highest-quality water washable resins on the market.

The most notable aspect of Phrozen water washable resin is its print quality. I can’t even exaggerate when I say that prints made in this material come out with incredible detail and precision.

Plus, this resin is also very tough, with a Shore Hardness rating of 80D, which is equivalent to the rigidity of an aluminum computer case. Compared to other water washable resins on the market, this is very strong, making Phrozen’s WW resin a great option for any prints that might require some strength.

Sadly, Phrozen’s resin only comes in two colors: gray and black. But, don’t worry, because painting resin 3D prints is super easy, especially when they come out as smooth as they do when you use Phrozen’s Water Washable resin! 

Anycubic is one of the largest manufacturers of both FDM and resin 3D printers in the world, and the company’s WW resin is very high-quality.

Anycubic WW resin, just like Elegoo’s option, can handle up to 8K print quality. As such, it’s a natural winner when it comes to printing high-detail models, such as miniatures.

On top of its mechanical properties, eSun Water Washable resin also handles detail on prints well. Unfortunately, though, this resin only comes in three colors, including beige, grey, and white, and each bottle costs a bit more than the others on this list.

But, if you’re looking for a resin that will make the washing process a breeze while not hurting the mechanical properties of your prints, then eSun Water Washable resin is for you!

What is Water Washable Resin?

Water washable resin is a type of 3D printing resin that contains an ingredient that’s water-soluble. As such, you can wash 3D prints made in this type of resin with water instead of a foul-smelling chemical like isopropyl alcohol or acetone, which is required for parts printed in regular resin.

Besides its easier washing process, water washable resin performs practically the same as regular 3D printing resin. Because of this, you shouldn’t have to make too many adjustments to your 3D slicer settings to achieve high-quality prints in this type of resin. We’ll go over some setting suggestions later, though!

On a different note, WW resin typically costs $5-10 more, per 1-kg bottle, than regular 3D printing resin. This is likely because this type of resin requires a special ingredient, which gives the material its water-washability property.

Finally, it’s worth mentioning that, today, there are tons of WW resin options, and each differs slightly in its mechanical properties, lie tensile strength, impact resistance, and flexibility. As such, even if two resins are both water washable, it’s still worth checking the reviews and listed product features to find which one is best. 

How to 3D Print With Water Washable Resins?

As I mentioned, water washable resin prints very similar to regular 3D printing resin, and no additional hardware for your printer is required. However, because WW resin contains some different ingredients than regular 3D printing resin, you’ll have to adjust a few slicer settings to achieve the best print results with WW resin.

The first setting you should adjust is the exposure time. Exposure time is a slicer setting for resin printers that control how long each layer of a print is exposed to UV light so the resin can properly solidify. Water washable resin, because of the water-soluble chemical mixed in, requires longer exposure times than normal resin.

While there isn’t one exposure time that works for all water washable resins, 10 to 15 seconds should work for most water washable resins. For reference, the typical exposure time for regular resin is 6-10 seconds.

On a related note, you should also increase the bottom exposure time (exposure time for the first layer). Instead of 60 seconds, which is common for regular 3D printing resins, I recommend setting the bottom exposure time to 70-75 seconds when using WW resin.

These are the two main settings that you should change when using WW resin, but you can also change other settings for further tuning.

I strongly suggest checking with the manufacturer of your resin bottle for their full list of recommended slicer settings as they know the material best. You can typically find the recommendations on the label of the resin bottle or on the online product page.

How Long Does Water Washable Resin Take to Dry?

Parts printed in water washable resin should only take a few minutes to dry after the washing process. Personally, I like to leave the part for 10-20 minutes on top of a rag so all of the water can get out of the model before the curing process.

And, on this note, water washable prints should take about the same time to cure under UV light as regular resin 3D prints. For most prints, 2-5 minutes does the trick perfectly!

How to Dispose Water Washable Resin?

While water washable resin might sound more eco-friendly, it’s just as toxic as regular 3D printing resin. As such, you should take the same precautions when handling and disposing of water washable resins.

Sadly, you can’t simply dispose of WW resin by pouring it down your sink. In fact, you can’t actually dispose of the resin at all when it’s in a liquid form because that’s when it’s most toxic. Moreover, pouring resin down a drain can not only cause damage to your pipes but can also hurt the environment because the toxic resin will run throughout the water or sewer system. 

Instead, to dispose of leftover WW resin, you have to first solidify it and then throw it out. To do this, simply pour all of the resin into a bottle (if it’s not already in one), remove the cap, and place the bottle outside when it’s sunny. The sun’s UV rays will eventually cure and solidify all of the liquid resin in the bottle, and, from there, you can throw it in the trash.

Do You Need IPA for Water Washable Resin?

No! That’s the whole point!

Parts printed in water washable resin don’t require a special solvent chemical, like isopropyl alcohol or acetone, for the washing process. While you might be able to use IPA to wash parts made in water washable resin, you shouldn’t. Not only is it more expensive than using water (free), it also might cause a chemical reaction that degrades the quality of your print.

You’ll only need IPA (or acetone) if you’re washing parts printed in traditional resin because IPA is one of the few solvent chemicals for normal resin.

Is Water Washable Resin More Brittle?

Unfortunately, yes. Parts printed in WW resin are typically weaker and more brittle than parts made with normal resin (or other printing materials). This stems from the inferior mechanical properties, mainly tensile strength, of the ingredients used in WW resin compared to those in normal resin.

But, for clarification, the difference in brittleness between the two types of resin is pretty small. And, compared to FDM 3D printing materials like ABS and PETG, both resin materials are relatively weak and are better suited for printing decorative and display models, like miniatures, than functional parts.

Is Water Washable Resin Safer?

No! Water washable resin is basically just as toxic and dangerous as regular 3D printing resin, as I mentioned when I went over the disposal process.

Because of this, make sure to follow the same precautionary measures when handling WW resin. This means wearing gloves when pouring resin or picking up un-cured prints. And, if you want to be the most safe, you might also want to wear a face mask to prevent the resin fumes from damaging your lungs.

Advantages & Disadvantages of Water Washable Resin

Below, I’ve listed the advantages and disadvantages of water washable resin, as it compares to traditional 3D printing resin. Note that these pros and cons are general and aren’t specific to any one WW resin product.


  • Much easier and less expensive washing process
  • Prints very similarly to regular resin
  • Many different options for water washable resin
  • Easier to clean resin spills


  • Slightly more expensive than regular resin
  • Requires some minor adjustments to the slicer settings
  • Tends to yield weaker and more brittle parts
  • Printing defects are more common
  • Longer drying time

Water Washable Resin VS Normal Resin

The main difference between water washable and normal resin is the washing process for parts. As I’ve explained, models printed in WW resin can be washed with water, while parts made in regular 3D printing resin must be washed in a solvent chemical, like IPA or acetone.

But the washing process isn’t the only difference between these two types of resins.

Another major difference is that water washable resin requires longer exposure times, leading to a longer print time. While each layer printed in WW resin only takes a few seconds longer to cure than if printing with regular resin, this time adds up quickly. A large print job might take an extra hour when printed with WW resin.

Additionally, normal resin boasts better mechanical properties, including tensile, flexural, and extension strength, than WW resin. Even though the difference in strength between the two types of resin is fairly small, it’s enough to make normal resin noticeably better than the alternative when it comes to printing functional parts, like a door hinge or bike part.

Lastly, water washable resin tends to cause more printing defects, like layer delamination and cracking, than normal resin. While increasing the exposure time can mitigate these issues, there’s definitely an apparent drop in the quality of prints when using water washable resin compared to normal resin.


Overall, if you despise the washing process for your resin 3D prints, consider getting some water washable resin.

Water washable resin prints just like regular resin, offers similar mechanical properties, and costs only a few bucks more, per bottle, than regular 3D printing resin. And, parts made in this resin can be washed after printing with just water. No foul-smelling chemicals like IPA or acetone are needed!

The best water washable resin I’ve found is from Elegoo. Elegoo’s standard water washable resin comes in a wide variety of colors, prints super well with the manufacturer’s recommended slicer settings, and doesn’t cost too much! Plus, it makes the washing process a total breeze.

But, if you’ve got some extra money in your budget and want to maximize the print quality, I recommend Phrozen’s Aqua Gray water washable resin. The resin can handle exceptional detail on models, and it’s also decently strong.
