Which of the following thermoplastics is known for its ease of printability in FDM?

PLA, or Polylactic Acid, is widely recognized for its ease of printability in Fused Deposition Modeling (FDM) due to several factors. First, PLA has a lower melting temperature compared to other thermoplastics, which allows it to be extruded easily and adhere well to the print bed. This characteristic reduces the risk of warping and makes it a beginner-friendly material.

Additionally, PLA offers excellent layer adhesion during printing, resulting in stable structures and high-quality surface finishes. Its flow characteristics enable it to transition fluidly through the nozzle without frequent clogs, which is a common issue with more viscous materials. Furthermore, PLA is available in a variety of colors and can be printed at relatively low temperatures, making it compatible with most standard FDM printers.

These attributes contribute to PLA's popularity among new users and hobbyists, as it simplifies the printing process while still producing satisfactory results. In contrast, materials like polycarbonate, nylon, and ABS typically require more advanced techniques, higher temperatures, or specific printer setups to achieve optimal results.
