No, PETG does not dissolve at the corners. PETG is a thermoplastic polymer that is known for its chemical resistance and stability, so it does not easily dissolve in common solvents. This makes it a popular choice for 3D printing and other applications where chemical resistance is important. However, PETG can be affected by certain chemicals, so it's important to be aware of its limitations and use appropriate handling and storage practices. **

Homemade PETG filament can potentially damage a 3D printer if it is not made to the proper specifications and quality standards. The quality of the filament, including its diameter, consistency, and impurities, can affect the performance of the 3D printer and potentially cause clogs, jams, or other issues. It is important to carefully follow the proper procedures and use high-quality materials when making homemade filament to minimize the risk of damaging the 3D printer. Additionally, using homemade filament may void the warranty of the 3D printer, so it is important to consider this before using homemade filament. **

When printing with PETG for the first layer, it is important to ensure that your bed is leveled properly to avoid any adhesion issues. Adjust the nozzle height to get a good squish on the first layer, which helps with adhesion. Use a higher bed temperature (around 80-90°C) to help the PETG stick to the bed better. Additionally, printing the first layer at a slower speed can also help improve adhesion and overall print quality. **

You can buy PETG and PLA filament at the cheapest price from online retailers such as Amazon, eBay, or AliExpress. These platforms often have a wide range of options and competitive prices due to the large number of sellers. Additionally, you can also check for discounts and promotions on these websites to get the best deal on filament. Keep in mind to read reviews and check the seller's reputation before making a purchase to ensure the quality of the filament. **

For optimal frictional adhesion on a PETG cone, you would need an inclination angle that is greater than the angle of repose for the material. The angle of repose for PETG is typically around 30-40 degrees, so you would need an inclination angle greater than this range to ensure optimal frictional adhesion. A higher inclination angle would provide more surface contact and therefore better adhesion between the cone and the surface it is placed on. **

Yes, piercings are considered a fashion trend. Over the years, piercings have become a popular way for people to express their individuality and personal style. From ear piercings to nose, lip, and body piercings, they have become a common form of self-expression and a way to enhance one's appearance. Many people view piercings as a fashion statement and use them to accessorize and complement their overall look. **

It is difficult to determine if something is a fashion trend without more specific information about what is being referred to. Fashion trends can vary widely and can be influenced by a variety of factors such as popular culture, social media, and celebrity endorsements. Without more context, it is challenging to definitively say whether something is a fashion trend or not. **

No, circumcision is not a fashion trend. Circumcision is a cultural, religious, or medical practice that has been performed for thousands of years in various societies around the world. It is not a passing trend, but rather a deeply rooted tradition with significant historical and cultural significance for many communities. While there may be fluctuations in circumcision rates over time, it is not accurate to categorize it as a fashion trend. **
