These little ghost snails/slugs would love to be your friend for Halloween (or year-round)! They promise not to eat your plants, because ghosts don't need food. File by: Layers in Green (printed under a commercial license) What is PLA? Polylactic acid (PLA) filament is a thermoplastic polyester made from renewable resources like corn starch or sugarcane. It's a common material used in 3D printing. Properties: Biodegradable: PLA can be broken down in composting plants or under certain conditions with high heat Recyclable: PLA can be melted and reused without significant damage Non-toxic: PLA doesn't emit toxins or fumes when melted Low shrinkage: PLA doesn't deform after cooling, making it ideal for 3D printing Low melting point: PLA has a melting point between 80 and 150 °C (176 - 302°F) Good layer adhesion: PLA has excellent layer adhesion, making it good for creating intricate designs Production: PLA is made by breaking down the starch in plants like corn or beets into lactic acid PLA is the second most produced bioplastic
