Deciphering PLA vs PETG: A Mold Maker’s Guide to Material Selection

In the intricate world of mold making, choosing the right material is akin to laying the foundation for success. Polylactic Acid (PLA) and Polyethylene Terephthalate Glycol (PETG) are two prominent contenders in this arena, each offering unique properties and applications. In this guide, we’ll unravel the differences between PLA vs PETG, empowering mold makers to make informed decisions in material selection.

Introduction to PLA and PETG

PLA is a biodegradable thermoplastic derived from renewable resources like corn starch or sugarcane. Renowned for its eco-friendliness and ease of use, PLA is favored for its versatility in creating intricate designs.

On the other hand, PETG boasts exceptional strength, impact resistance, and transparency. Widely utilized across various industries, PETG stands out for its durability and versatility in mold making applications.

Properties and Characteristics

• PLA: Featuring a low melting temperature, PLA offers smooth surface finishes and intricate details. Its biodegradable nature and ease of printing make it ideal for eco-conscious projects. However, PLA may not withstand high-temperature environments.
• PETG: With a higher melting temperature, PETG excels in strength, durability, and chemical resistance. Its transparency and impact resistance make it suitable for a wide range of applications, including those requiring visibility and robustness.
