So, you’ve just finished printing a jaw-dropping model on your 3D resin printer, and it looks stunning. Well, almost. Still, the finished look is only temporary, since it’s still covered in sticky resin. If you disregard printing maintenance, your prints will fall apart fast.
All types of resin printing need cleaning since it is what makes your parts look finished. If you have been in the resin printing community for a while, you already know there are more challenges than you might expect.
The hard part is not finished when your print is printed. Think about the gooey surface. That is an uncured resin that should be washed before you finish curing it.
If you skip these dental practices, you risk getting surfaces covered in sugar and bacteria, teeth that look bad, or a damaged jaw, and discomfort.
In case you are aiming for that freshly rated print feeling and want your prints to look like they were made at a professional shop, look no further.
Here are the steps to clean up your prints in a safe way so that your workspace stays neat.
Why It’s Important to Wash and Clean Resin Prints
Leaving the cleaning out is much like baking a cake and not bothering to remove it from the pan. Prints that are not washed out are like works in progress instead of completed pieces.
3D resin printer models are covered in a layer of liquid resin when they come off the build plate. That stuff’s toxic, sticky, and if left on, can degrade your model’s detail and make curing a mess. Cleaning ensures that the structure of your print stays intact, sharp, and safe to handle.
Plus, if you want your prints to last (and not warp, crack, or irritate your skin), proper cleaning is your first line of defense.
4 Practical Ways to Wash and Clean Resin Prints
Alright then, it’s time to dive into the material—however, just metaphorically. Wear gloves every time you have a job to do outdoors. Several cleaning options exist, and what you use, the area you have, and what resin you work with might lead you to different cleaning methods.
Each technique has its perks. Let’s walk through the four most popular ones and figure out what fits best for your workflow.
1. Alcohol Cleaning (Isopropyl Alcohol / IPA)
The classic. This method is the gold standard when it comes to 3D resin printer post-processing. Pouring 90% or higher Isopropyl Alcohol (IPA) on top of uncured resin makes it dissolve swiftly.
Here we will explain how to do it.
- Add IPA with at least 90% alcohol concentration to a container.
- Gently dunk and swirl your print for 3–5 minutes
- Use a soft brush to scrub stubborn resin
- Let it dry or rinse it with a clean IPA
Keep in mind, though, IPA can evaporate quickly and fill your room with a pretty nasty smell. Always ventilate your space and use gloves. Also, don’t reuse murky IPA forever—it'll just smear resin back on your prints.
2. Ultrasonic Cleaning
If you are looking to step up your cleaning skills, an ultrasonic cleaner is the solution. It works like the lazy genius’s version of cleaning prints.
This little machine uses tiny sound waves to shake loose uncured resin, even from the tiniest nooks and crannies your brush couldn’t reach.
Why people love it:
- Gets into the tiny crevices without damaging parts
- Works well with IPA or resin-safe cleaning fluids
- It’s fast, effective, and hands-free
Perfect for folks printing intricate models or batches that need a reliable clean every time.
3. Water Cleaning with Water-Washable Resin
Now we’re talking! If you’re using water-washable resin, cleaning is way simpler and safer. No solvents, no fumes—just warm tap water and a brush.
Steps to follow:
- Rinse your print in warm water (not hot)
- Use a soft toothbrush to scrub the details
- Dry the print with paper towels or let it air dry
Pro tip: Stick to lukewarm water, not hot—it keeps your structure intact. And don’t leave prints soaking forever. Just wash, scrub, rinse, and dry.

4. Two-Stage Cleaning Method
This method is for those chasing perfection. If your model has insane detail or you're printing for professional use, this double-duty approach is the one to beat.
Here's how to do it:
- First bath: dunk in used IPA to remove heavy resin
- Brush gently to loosen the residue
- Second bath: Use clean IPA or clean water if you're using water-washable resin
- Final air-dry before curing
The two-stage method makes sure you’re not smearing dirty IPA back onto your prints and keeps every corner crisp and residue-free.
Important Precautions When Cleaning Resin Prints
Now that you’re cleaning like a pro, let’s talk safety. This part isn’t optional. Resin is no joke if you’re careless.
Always treat your workspace like a mini lab—because you’re working with chemicals that can irritate the skin, damage surfaces, and mess with air quality.
Here’s what you must keep in mind:
- Wear nitrile gloves (latex might break down in resin)
- Use safety glasses if splashing is a risk
- Always work in a well-ventilated area or use a fume extractor
- Seal your IPA containers to reduce evaporation.
- Dispose of waste (dirty IPA, used resin) per local hazardous waste rules.
Also, avoid pouring IPA or resin water down the sink. That’s a one-way ticket to plumbing regrets and environmental damage.
Conclusion
Cleaning resin prints might sound tedious, but it’s honestly where the magic happens. A well-cleaned model looks smoother, cures better, and feels more “finished.” It's not an afterthought—it's the final brushstroke on your masterpiece.
Whether you're sticking to IPA, getting fancy with ultrasonic cleaners, going green with water-washable resin, or combining methods like a pro, the goal is the same: crisp, clean, flawless models that don’t just look great—they last.
And if you're tired of juggling containers, gloves, and IPA bottles like a mad scientist, here's the upgrade you need: the HeyGears Wash and Cure Station. It's efficient, safe, and super convenient. Just load your print, push a button, and let the station do the heavy lifting.
