PLA
Material Data Sheet
PLA
PLA is a renewable plastic material offered as a low-cost material option for fast-draft part iterations. 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 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. Ideal applications for PLA include fast, early concept modeling and low-cost prototyping.
Color options:
Black, White, Light Gray, Medium Gray, Red, Blue, Natural Translucent, Red Translucent, Blue Translucent, Yellow Translucent, Green Translucent
