Practical questions and answers
3D printing or conventional manufacturing?
Compare printing with a specific process such as machining or molding, not with an undefined conventional method. Printing builds layers, machining removes stock and molding uses tooling. Quantity, geometry, material and tolerances drive the choice.
When does quantity change the decision?
Printing may avoid tooling for a limited trial, while per-part time and finishing may favor another process later. Compare setup, unit cost, rejected parts and revisions. A break-even quantity must be calculated for the actual project, not assumed.
What must be tested before selecting a process?
Check mating fit, performance in the load direction and surface finish. Moving from printing to molding or machining may require redesign. A successful printed prototype does not prove that the same geometry suits every manufacturing method.
| Process | Key question |
|---|---|
| Printing | Do geometry, material and layer direction suit the test? |
| Machining | Can tools reach critical surfaces and dimensions? |
| Molding | Does the planned volume justify tooling? |
