High-temperature resistance is defined as the ability of a material to withstand elevated temperatures without undergoing physical or chemical changes. For example, materials like ceramic and certain food-grade plastics are designed to resist high temperatures. These materials maintain structural integrity, preventing deformation or melting.

The mechanisms involved include thermal expansion, which is the tendency of materials to change in size with temperature changes. High-temperature resistant materials exhibit low thermal expansion, meaning they retain their dimensions when exposed to heat. Additionally, certain materials have high melting points, making them suitable for cooking applications.

Specific conditions that contribute to the need for high-temperature resistance include exposure to boiling water, hot oils, and the high temperatures generated during cooking. For instance, a 3D printed spatula that is used to flip frying food must withstand temperatures above 200 degrees Celsius (392 degrees Fahrenheit) without melting or warping.
