What type of AM material is commonly used in filaments, liquids, and powders?

Polymers are widely used in additive manufacturing (AM) across various forms, including filaments, liquids, and powders. This versatility is one of the reasons why polymers are the most commonly used material in 3D printing technologies. In filament form, polymers like PLA (polylactic acid) and ABS (acrylonitrile butadiene styrene) are favored in Fused Deposition Modeling (FDM) processes. In resin form, various liquid polymers are utilized in Stereolithography (SLA) and Digital Light Processing (DLP) methods. Moreover, powdered polymers are often employed in Selective Laser Sintering (SLS) processes. The ability to manipulate polymers into multiple physical states makes them highly adaptable, allowing for a wide range of applications and products in the additive manufacturing industry. This adaptability and the widespread availability of polymer materials contribute to their predominance in AM practices.
