Brittleness Brittleness refers to a material’s tendency to fracture or break under stress without significant deformation. In 3D printing, brittle filaments like some types of PLA or certain composites can snap during extrusion or handling. Factors contributing to brittleness include material composition, moisture absorption, and improper storage. To reduce brittleness, users should store filaments in dry, airtight containers and ensure proper printing temperatures. Understanding a material’s brittleness helps in selecting the right filament for specific applications and improving the durability of printed parts. |
