Can you use 70 isopropyl alcohol to clean resin prints? Yes, you can use 70% isopropyl alcohol to clean resin prints effectively. It works well to remove uncured resin from 3D printed parts.
When delving into the realm of 3D printing, specifically resin printing, post-processing is a crucial step to achieve flawless prints. Among the various substances employed for cleaning, 70% isopropyl alcohol is a popular choice owing to its balance of effectiveness and relative safety.
This type of alcohol swiftly dissolves uncured resin, making it an asset for print makers striving for neat and detailed models. While utmost precision is vital in creating exceptional resin prints, the cleaning process equally contributes to the final outcome, with isopropyl alcohol being a key ingredient to success. This introductory guide aims to assist hobbyists and professionals alike in understanding the importance of proper post-processing, ensuring their prints are not only aesthetically appealing but also structurally sound and ready for display or functional use.
The Role Of Isopropyl Alcohol In Post-processing Resin Prints
Isopropyl alcohol (IPA) is a key player in cleaning and finishing 3D resin prints. Fine details and clarity emerge when IPA removes the uncured resin. Proper use ensures prints are smooth, clean, and ready for use or painting.
Properties Of 70% Isopropyl Alcohol
70% isopropyl alcohol is a preferred cleaning agent for resin prints. Its properties make it suitable for this sensitive process:
- Evaporation rate: Quick-drying, decreasing waiting time.
- Strength: Effective at breaking down uncured resin without damaging the print.
- Safety: Less harsh than stronger concentrations, safe for most users.
Comparison With Other Solvents
Selecting the right solvent is crucial. Here’s how 70% IPA stacks up:
| Solvent | Cleaning Efficacy | Safety | Drying Time |
|---|---|---|---|
| 70% IPA | High | High | Fast |
| 90%+ IPA | Higher | Lower | Faster |
| Acetone | Very High | Low | Fast |
| Water | Low | High | Slow |
70% IPA offers a balance. It cleans effectively without excessive harshness. A perfect middle ground for both hobbyists and professionals.

Effects Of Isopropyl Alcohol On Different Resin Types
Understanding how isopropyl alcohol (IPA) interacts with various resin types is crucial for any 3D printing enthusiast. The focus is on cleaning the resin prints without damaging the material integrity or surface finish. Selecting the correct concentration and exposure time is key.
Impact On Print Integrity And Surface Quality
Isopropyl alcohol can deeply affect a resin print’s physical properties. Its effects range from slight changes in color and texture to potential cracking or warping. The outcome largely depends on interaction time and IPA concentration.
- Short exposure can enhance print quality.
- Overexposure leads to weakened structures.
- 70% IPA is generally safe for short durations.
For consistent results, maintain detailed cleaning protocols accounting for the specific resin used.
Compatibility With Common Resin Formulations
| Resin Type | Compatibility | Suggested IPA Concentration |
|---|---|---|
| Standard | Highly Compatible | 70%-90% |
| ABS-like | Moderate Compatibility | 70%-80% |
| Flexible | Low Compatibility | 60%-70% |
| Water Washable | Not Recommended | N/A |
Standard resins typically handle IPA well, while flexible resins may suffer. Water-washable resins do not require IPA cleaning and can be damaged by it. Always review the resin manufacturer’s guidelines.
Optimal Use Of 70% Isopropyl Alcohol For Resin Cleanup
Resin 3D printing offers incredible precision and detail, but it also requires thorough cleanup to maintain the quality of the prints. 70% isopropyl alcohol (IPA) is widely used to clean resin prints due to its effectiveness and availability. When used properly, it can remove uncured resin and leave prints spotless.
Step-by-step Cleaning Process
- Remove the print: Take your resin print off the build plate gently.
- Submerge the print: Place the print in a container filled with 70% IPA.
- Swirl and soak: Gently swirl the liquid or let the print soak for a short time.
- Brush off excess resin: Use a soft brush to gently clean the surfaces.
- Rinse the print: Remove from IPA and rinse with fresh alcohol or water.
- Dry the print: Let the print air dry or use compressed air to speed up the process.
- Cure if necessary: Expose to UV light to fully cure, if required.
Precautions And Safety Measures
- Wear gloves: Always protect your skin from IPA and uncured resin.
- Work in a ventilated area: Ensure proper airflow to avoid inhaling fumes.
- Avoid fire hazards: Keep IPA away from open flames and heat sources.
- Store safely: Keep IPA and resin in closed containers when not in use.
- Dispose of waste properly: Follow local regulations for disposal of resin and IPA waste.

Alternatives To Isopropyl Alcohol For Cleaning Resin Prints
Cleaning resin prints is crucial for a crystal-clear finish. While 70% isopropyl alcohol (IPA) is a popular choice, there are effective alternatives. Let’s explore options that keep your prints spotless without IPA.
Ethanol vs. Isopropyl Alcohol
Ethanol Vs. Isopropyl Alcohol
Ethanol, also known as grain alcohol, is a potent alternative. It works similarly to IPA but is often gentler on certain plastics. Here’s a quick comparison:
| Aspect | Ethanol | Isopropyl Alcohol |
|---|---|---|
| Strength | Strong | Very Strong |
| Drying Time | Fast | Faster |
| Safety on Plastics | Gentler | Varies |
Using Water and Detergents
Using Water And Detergents
Cleaning with warm water mixed with detergents can be effective. Follow these steps:
- Fill a container with warm water.
- Add a few drops of liquid detergent.
- Place the resin print in the solution.
