Lock baseline: —
Enable to lock your current configuration as a baseline, then change parameters to compare the delta.
Mechanical Properties
Toughness (Izod) ? Energy absorbed before fracture. Uses √(infill) curve — diminishing returns above ~70%.
—
kJ/m²
Stiffness (E-Modulus) ? Resistance to elastic deformation (bending). Linear relationship with infill density.
—
MPa
Hardness ? Surface resistance to indentation. Primarily a material property — intrinsic, not structural.
—
Shore D
Tensile Strength ? Max stress before failure. Pattern affects anisotropy — Lines pattern penalised for inter-layer weakness.
—
MPa
Estimated Part Mass
