Manufacturing strategy · Process and manufacturing decisions
Make or buy in additive manufacturing
Printer purchase price is only one part of in-house production. Operator time, data preparation, material handling, scrap, maintenance, inspection and idle capacity also count. Outsourcing has handover and delivery time in return.
In brief
In-house production is strong for frequent, urgent and well-controlled tasks. Outsourcing is strong for variable demand, many materials, production responsibility or missing process expertise. A hybrid model is often sensible.
Total cost, not machine price
Compare the finished inspected unit, not just build time and filament.
- Fixed
- Machine, space, drying, maintenance, software
- Variable
- Material, labour, energy, scrap, finishing
- Hidden
- Training, downtime, procurement, quality effort
Response time and utilisation
Immediate availability exists only when staff, material and machine are ready together.
- Recurring standard parts are easier to stabilise internally.
- Rare high-performance materials create storage and setup effort.
- Peak demand can be outsourced without holding permanent capacity.
Hybrid model
Splitting tasks can be faster and more robust than an absolute decision.
- Simple iteration samples in-house, demanding materials outsourced.
- Emergency capacity in-house, recurring batches with a qualified supplier.
- Shared data and revision logic for both routes.
