PLA 3D printer filament Material Characteristics: 1. PRILINE PLA ?Polylactic Acid? is one of the most popular materials for 3D printing. Our PLA filament has a relatively low melting temperature, low warp properties and is biodegradable. It?s suitable for home printers, hobbyists, and schools. 2. PLA filament has a low shrinkage rate and it is very rigid with minimal flex. This material can print extremely high resolution models and is perfect for a wide range of uses. 3. PLA filament has a huge range of vibrant colors and opacity for that perfect look whether it is artistic or utilitarian. PLA can be printed without the use of a heat bed, and can stick to glass or a PCB plate with a binder such as hairspray or white glue for a curl free print.

PRILINE 3D Printer Filament Storage Tips: 1. Since PLA material is made from biodegradable sources, it is susceptible to moisture. We recommended storing filament in a sealed plastic bag or box after each print. 2. If the filament gets damp, you can bake it in an oven with 50°C(122°F) for about an hour to restore its dryness. Friendly Reminder(After Use): Be sure to insert the free end of the filament into the hole to avoid the filament being tangled for next time use.
