I’m looking to print a flask, will alcohol break down the plastic?

Our lab testing report is included in the Amazon product photos. There you can see what FDA tests were conducted. The plastic was tested in an alcohol solution, per the FDA requirements. Please review the testing report to view the percentage of alcohol that this material is certified for.

Is this material considered dishwasher safe after using for 3d print?

The lab test results are attached as an image to this listing. The attached report states that the filament was tested at 250 degrees Fahrenheit for 2 hours. After this test was completed, the total extractives were at the legal limit. Please review the results. Your issue is less about if the material will be safe to be machine washed. The greater concern is warping. I would print at 100% infill and wash only on the top rack. To further increase the dimensional stability of your parts, you should anneal them. There are resources online on how to do that. I hope this helps you.
