Its glass transition temperature is relatively low, limiting its use in high-heat environments but making it ideal for applications requiring easy forming at moderate temperatures. Furthermore, its high stiffness ensures that printed parts or molded components retain their shape effectively, reducing the need for complex support structures in manufacturing processes.
Current Limitations and Material Comparisons Despite its many benefits, PLA properties dictate certain limitations that must be considered during material selection. This process utilizes annually renewable plant resources, distinguishing it fundamentally from petroleum-based polymers like ABS or polypropylene.
