Acetone-based nail polish removers can be used to smooth PLA
When using acetone to smooth PLA, it is important to be cautious as it can soften the material if exposed for too long. It is recommended to gently heat the plastic and use a utensil to smooth out the surface. A hairdryer can be a useful tool for this process, but care must be taken to only lightly melt the outside of the model.
In addition to acetone, other methods for smoothing PLA include using a hairspray product called Got2beGlued, or mechanical removal techniques such as sanding with high-grit sandpaper. Some people also experiment with different chemical mixtures, such as a methyl chloride and acetone mix, to find the best results for their specific application.
It is worth noting that while acetone can be effective for smoothing PLA, it may not be the best option for ABS. Acetone will dissolve ABS, so alternative solvents such as ethyl acetate-based nail polish removers or other filler materials like white Valejo putty may be more suitable for ABS models.
Overall, acetone-based nail polish removers can be a cost-effective and accessible option for smoothing PLA, but it is important to be mindful of potential issues with adhesion and to manage expectations as everyone's idea of smooth may differ.

Ethyl Acetate-based removers can remove PLA residue
Ethyl acetate is a highly effective solvent for breaking down and dissolving PLA. It is a common ingredient in non-acetone nail polish removers. While acetone is not very effective at dissolving PLA, ethyl acetate easily breaks it down. It also evaporates quickly, so it dissipates into the air soon after use.
Ethyl acetate can be used to remove support materials from 3D prints. This can be done by soaking the entire part in an ethyl acetate solution, which will completely dissolve the supports. If you are unable to print in two materials, you can 3D print the entire model in PLA and manually break off the supports. If there is any leftover material, you can dissolve it using ethyl acetate.
Ethyl acetate can also be used to smooth PLA prints. This can be done by applying a small amount of the chemical to the surface of the print or using ethyl acetate vapour. This will smooth out any imperfections on the surface of the print, resulting in a smooth, professional-looking finish.
To dissolve PLA residue from 3D printer nozzles, you can soak the nozzle in ethyl acetate for 15-25 minutes. After removing the nozzle from the solution, brush and wipe away any remaining bits of residue. It is important to then rinse the nozzle with water to remove any residual solvents.
While ethyl acetate is not particularly toxic, it is a potential carcinogen and can be absorbed into the skin easily. It is also flammable, so it is important to take safety precautions when using it. This includes wearing gloves and working in a well-ventilated area to avoid inhaling fumes.

Acetone-free removers can smooth PLA without dissolving it
Acetone is a powerful chemical solvent that is often used to strip lacquers, paints, waxes, and resins. It is also a common ingredient in nail polish removers. While acetone is effective for cleaning and smoothing 3D prints made with ABS, it is not suitable for use with PLA. This is because acetone tends to make PLA rubbery or sticky rather than fully dissolving it, which can ruin the strength and surface finish of a print.
There are, however, alternatives to acetone for smoothing PLA prints. One option is to use ethyl acetate, which is an organic ester compound with a clear liquid form and a fruity odor. It is a highly effective solvent for breaking down and dissolving PLA, and it can be applied directly to the surface of the print or used in vapor form.
Another alternative to acetone is to use manual techniques such as sanding. Sanding is a safe and effective way to smooth a PLA print, although it can be time-consuming. It involves using sanding blocks, sandpaper, and nail files to gradually remove the outer layer of the print. For best results, it is recommended to rub the sanding medium in circular motions against the grain of the print, starting with low-grit sandpaper and gradually increasing the grit level. The process can be finished with wet sandpaper to achieve a smooth and polished surface.
It is important to note that when working with chemicals, proper personal protective equipment (PPE) and good ventilation are crucial to ensure safety. Additionally, the specific brand and composition of nail polish or remover can impact its effectiveness and potential damage to PLA, as some may contain additional ingredients beyond the basic solvents. Testing on a small area or a swatch is recommended before applying any substance to the entire print.

Removers with ingredients like baby oil, lanolin, and fragrances may discourage adhesion
When it comes to the use of nail polish removers for polishing 3D prints, there are some important considerations to keep in mind. While nail polish remover can be used to smooth out 3D prints, the effectiveness of this method depends on the type of nail polish remover used and the material of the 3D print.
Nail polish removers with ingredients like baby oil, lanolin, and fragrances may not be ideal for this purpose as they can discourage adhesion. Lanolin, derived from the Latin terms lana (wool) and oleum (oil), is a natural product obtained from sheep's wool. It has emulsifying properties and is commonly used in skincare and cosmetic products due to its ability to mimic the skin's natural oils. However, lanolin can also act as a protective coating, potentially reducing the adhesion of the nail polish remover to the 3D print.
Baby oil, which is typically mineral oil or castor oil, can also hinder adhesion due to its greasy and oily nature. Fragrances, while enhancing the sensory experience, may not be necessary for the functionality of the nail polish remover and could potentially interfere with the adhesion process. Therefore, when selecting a nail polish remover for polishing 3D prints, it is advisable to choose one without these specific ingredients to ensure optimal adhesion and a smooth finish.
It is worth noting that acetone-based nail polish removers are commonly recommended for smoothing 3D prints, particularly those made with PLA (polylactic acid) material. Acetone is a solvent that can soften PLA, and while it may not completely melt it, prolonged exposure can affect the material. However, it is important to exercise caution when working with acetone due to its potential health and safety concerns.
Additionally, it is suggested to test the nail polish remover on a small area of the 3D print first to ensure it does not cause any discolouration or damage. Alternative methods for smoothing 3D prints include gently heating the plastic with a hair dryer and using a utensil to smooth out the surface. Overall, while nail polish remover can be used for polishing 3D prints, it is important to consider the ingredients and their potential impact on adhesion, as well as exploring other smoothing techniques for optimal results.

Mechanical removal of nail polish is possible with a knife and sandpaper
While nail polish removers are typically the go-to method for removing nail polish, other methods can be used, such as mechanical removal with a knife or sandpaper. However, it is important to note that picking, filing, or scraping off nail polish can damage your nails and cause white spots or other irritation. Therefore, it is recommended to use alternative methods with caution.
When it comes to 3D prints, specifically PLA models, there is some debate about the effectiveness of nail polish remover. Some sources suggest that acetone, a common ingredient in nail polish removers, can be used to smooth PLA prints. However, others argue that acetone may not be strong enough to dissolve PLA effectively and that the success of this method depends on the purity of the PLA and the specific ingredients of the nail polish remover.
In terms of mechanical removal, using a knife to scrape off nail polish from 3D prints is not recommended as it may damage the surface of the print. On the other hand, sandpaper can be an effective tool for removing nail polish from 3D prints. One source mentions using 1000-grit sandpaper with water to sand the surface of a PEI sheet, reviving the sheet and improving adhesion. This method may also be applicable to removing nail polish from PLA models or other 3D printed objects.
It is worth noting that there are alternative methods for removing nail polish from nails and 3D prints. For nails, some household products such as toothpaste, alcohol, or hand sanitizer can be used. As for 3D prints, one suggestion is to gently heat the plastic and use a utensil to smooth out the surface, being careful not to overheat and melt the model.
In conclusion, while mechanical removal of nail polish with a knife is possible, it may cause damage. Sandpaper, particularly fine-grit sandpaper used with water, can be a more effective and safer method for removing nail polish from both nails and 3D prints. However, as with any removal technique, caution should be exercised to avoid unwanted outcomes.
