A renewable, easy-to-print thermoplastic for fast, low-cost rapid prototyping, concept modeling, and educational applications.
Polylactic Acid (PLA) is a versatile thermoplastic derived from renewable resources such as corn starch or sugarcane. As a material, it is characterized by its high stiffness and low melting point, which allows it to be printed at lower temperatures and higher speeds than materials like ABS. This efficiency makes PLA a highly accessible and easy-to-use option, particularly for rapid design validation where speed and cost are critical factors.
With good tensile strength and higher stiffness than ABS, PLA is well-suited for producing dimensionally stable concept models and non-functional prototypes. Its properties are ideal for parts that need to hold their form for visualization, fit checks, and early-stage design verification. While not intended for high-stress functional applications, it provides excellent reliability for form and fit evaluation.
PLA is optimized for a streamlined printing process, especially in the fast-draft mode available on Stratasys F123 Series printers. This capability enables designers and engineers to produce and evaluate concepts in a fraction of the time. Parts printed in PLA use a simple breakaway support structure, allowing for fast, tool-free removal of supports and reducing post-processing time.
PLA is positioned as an ideal material for the earliest stages of the product development lifecycle. Its primary applications include low-cost, rapid concept modeling and prototyping where multiple iterations are needed quickly. Its non-toxic, low-fume nature also makes it a safe and popular choice for educational settings, from secondary schools to university engineering departments.
