Process Selection Flowchart

Q1

Does the part require metal?

YES →

CNC Milling or Plate Fab

Strength, heat, or regulatory requirement

NO →

Consider polymer

Weight, corrosion resistance, or cost priority

Q2

Is tolerance tighter than ±0.005"?

YES →

CNC Milling (±0.002")

Bearing fits, press fits, threaded bores

NO →

FDM or SLS viable

Housings, ducts, brackets with clearance fits

Q3

Does geometry have internal channels or undercuts?

YES →

SLS or FDM with supports

Seed metering channels, hydraulic passages

NO →

CNC preferred for metal

Prismatic parts, plates, flanged components
