Dimensional Accuracy Dimensional accuracy in 3D printing refers to how closely a printed object’s dimensions match the original CAD design. It is a critical metric for applications where precision is essential, such as engineering parts, prototypes, or assemblies. Dimensional inaccuracies can arise from factors like material shrinkage, over-extrusion, poor calibration, or environmental conditions. To achieve better accuracy, users can adjust slicer settings (e.g., flow rate, nozzle temperature), calibrate the printer’s axes, and compensate for material-specific behaviors. High-end printers often include features like closed-loop systems or advanced sensors to enhance accuracy. Regularly testing with calibration models ensures consistent results, especially when working on tight-tolerance projects. |
