Stratasys® PLA 3D Printing Polymer
Categories: Polymer; 3D Printing/Additive Manufacturing Polymer; Renewable/Recycled Polymer; Thermoplastic; Polylactic Acid (PLA) Biopolymer

Material Notes: PLA is a renewable plastic material offered as a low-cost material option for fast-draft part iterations. Available on the office-friendly Stratasys F123™ Series 3D printers, PLA offers a higher stiffness than ABS and its low melting point and HDT mean less heat and power required to print parts. PLA works well at high speeds, specifically fastdraft mode on the Stratasys F123 Series, for quick concept verification and design development. PLA offers good tensile strength and is available in a wide range of colors, including a variety of translucent colors. Applications for PLA include fast, early concept modeling and low-cost prototyping.
