In my experience, printers with a sturdy frame, heated bed, and all-metal hotend tend to give more consistent results with tougher plastics like PETG or Nylon. Also, the availability of well-prepared stl files for 3d printing can make a big difference—having models that are tested and optimized reduces trial-and-error. I’ve found sites like Gambody helpful because they offer professionally designed files with detailed instructions, which is especially useful when working with high-performance materials. Balancing cost, reliability, and compatibility with your intended prints is key.
