Comparison of the fast mould tool prototyping process.

Minimum Feature Size Aspect Ratio Dimensional Accuracy Young’s Modulus Roughness (Ra) Time
Micromilling 50 µm for sunk features 1.5 (features in the range between 50 and 100 µm) 20 µm 180 GPa 0.5–1 µm 6 days
LIGA and LIGA like processes 100 nm 2 (features in the range between 10 and 100 µm) 5 µm 170 GPa <15 nm 30 days
Selective laser melting 100 µm 6–10 (features width is larger than 100 µm) 50 µm 180 GPa 20~30 µm ~20 min
