In recent years, 3D printing has evolved from a pure prototyping technology into a serious production method. What once served as a tool for rapid model development is now increasingly being used in serial manufacturing.

Why the Leap from Prototype to Series Succeeds

Three key factors have enabled this transition:

  1. Complexity at no extra cost: Complex geometries that become expensive with injection moulding or milling come at no additional cost in 3D printing. Components can be designed freely based on their function.
  2. No tooling costs: Especially for small and medium batch sizes, the costs for injection moulding tools – which can quickly reach five-figure sums – are eliminated entirely. Production starts directly from the CAD file.
  3. Material diversity: From PA12 and TPU through to PEEK and metals such as aluminium or titanium – for virtually every requirement there is now a suitable printing material.

The Challenge: Reproducibility

The decisive difference between a successful prototype and production-ready manufacturing is reproducibility. Every component must exhibit exactly the same mechanical properties, dimensional accuracy and surface quality – regardless of whether it is the first or the thousandth piece.

This requires controlled powder management, thermal process monitoring and standardised post-processing. The standard ISO/ASTM 52920 now defines the requirements for quality-assured additive manufacturing processes.

According to the Wohlers Report, 18.5% of companies using 3D printing already employ the technology in serial production.

How exactly powder ageing is controlled, why thermal in-situ monitoring is critical, and what role digital twins play in quality assurance – we have summarised all of this in a detailed article:
