What changes at factory scale
A successful print answers one question. A repeatable production route must answer several more.
Can a large part be printed in one piece?
Sometimes, but usable build volume, thermal behaviour, handling, finishing and inspection access all constrain the decision. Splitting and joining may be more practical. Check the full route rather than treating the published machine envelope as a guaranteed finished-part size. Explore large-format routes.
Does additive manufacturing remove tooling?
It may remove a mould or die, but build plates, fixtures, supports, handling equipment and machining workholding may still be needed. Include those items in cost and lead-time comparisons. A printed tool can also support a conventional manufacturing process without the final product being additively manufactured.
Can unused powder always be reused?
No. Reuse must follow a material- and process-specific control plan covering exposure, contamination, sieving, blending and verification. “Unused” does not mean unchanged. Ask how recovered material is identified and how its history remains linked to subsequent builds. Follow the material-control route.
Is a printed metal part ready to use?
Usually not without a defined finishing and acceptance route. Heat treatment, separation, machining, cleaning and inspection may be required. Specify the final material condition and functional surfaces before accepting a quotation. Read the finishing sequence.
Can a process move unchanged to another machine?
Do not assume equivalence. Machine configuration, software, calibration, material handling and thermal behaviour can require verification or requalification. Even machines of the same model can need evidence that the transferred route meets the relevant requirements.
Does computed tomography prove a part has no defects?
No. Detection depends on material, geometry, resolution and the examination procedure. Inspection needs defined acceptance criteria. A feature smaller than the effective detection capability may remain unresolved, and different defect orientations or locations can present different challenges.
When is additive cheaper than machining or casting?
There is no universal volume threshold. Compare complete costs at the same finished condition, including tooling, yield, inspection and qualification. Geometry, part consolidation and delivery requirements may matter more than quantity alone. Use a whole-route cost comparison.
What should a supplier quotation include?
It should identify the process, material condition, finishing scope, inspection evidence, accepted quantity, lead-time assumptions and exclusions. Ask whether engineering changes, replacement builds, special packaging and subcontracted operations are included. Organise your questions in a production note.
