Tips from the 3D Printing Experts- If you’re new to 3D printing, MakerBot PLA Filament is a good material to start with because it’s easy to use and performs well on most prints. MakerBot PLA Filament adheres well to acrylic and to blue painter’s tape. Prints with a large bottom layer may have a tendency to curl. To prevent curling, turn on the raft option in MakerBot Desktop. Store MakerBot PLA Filament in a cool, dry place as it can absorb moisture from air and long-term exposure to humidity can compromise filament quality and performance. Be sure your build plate is level, clean, and oil-free before printing.
