PLA, or Polylactic Acid, is one of the most commonly used materials in FDM (Fused Deposition Modeling) 3D printing.
It was specifically developed for this technology, ensuring clean and warp-free printing.
PLA finds widespread use, primarily for rapidly and cost-effectively creating prototypes. Its low shrinkage makes PLA particularly suitable for large-scale parts.

Biodegradable
PLA is derived from cornstarch or grains and is biodegradable under industrial composting conditions.
Despite its compostability, PLA is very durable and can be used for long-lasting applications. Additionally, it is resistant to most chemicals.
Temperature Sensitivity
PLA is known for its hardness but is also brittle. It's sensitive to high temperatures, as it tends to lose its strength.
When exposed to direct sunlight, especially in a vehicle, PLA can soften and start to deform. Ideal for Segmented Bone and Skull Models Due to its matte surface finish, PLA is particularly well-suited for creating segmented bone and skull models, offering excellent detail and realism.
It can accurately reproduce anatomical features, making it valuable in medical and educational applications.

Mechanical Use
While PLA is not as mechanically robust as some other materials, it can still be used for mechanical applications with moderate loads. It is essential to consider its temperature sensitivity and brittleness when selecting PLA for mechanical parts. For applications where high mechanical stresses are not a concern, PLA can provide a cost-effective and accessible solution."

Examples of Applications:

• Point-of-Care 3D Printing: PLA can be used in point-of-care medicine to create customized medical devices and aids that meet the individual needs of patients.
• Surgical Planning: In the field of surgery, PLA 3D printing enables the creation of precise anatomical models that can be used for surgical planning and simulation.
• Housings for Medical Devices: PLA can be employed to manufacture casings and enclosures for medical devices and instruments, making them easier and more cost-effective to customize.
• Prototyping in Mechanical Engineering: PLA is ideal for the rapid and cost-effective production of prototypes for mechanical components and mechanical engineering applications.
• Demonstration Models and Rapid Prototyping: PLA is commonly used for creating detailed demonstration models and for rapid prototyping, making it an invaluable tool for students and researchers working on various projects.

The versatility of PLA in 3D printing enables a wide range of applications in research and medicine, from individual patient care to medical device engineering, surgical planning, and rapid prototyping for student research projects.
