The PLA 3D printing material offers strength and heat resistance ideal for low-cost, quick rapid prototyping in a wide range of colors. A stiff thermoplastic made from renewable resources, PLA is perfect for quick concept verification at a low cost. It works with fast-draft mode on the Stratasys F123 series and comes in 11 different color options. PLA also has a low melting point, which means it requires less heat and power to print parts.
