The process of commissioning a 3D printing service:

The process of commissioning a professional 3D printing service is divided into several steps:

1. Data creation and upload:
   The customer creates a 3D model of their component, usually in formats such as STL, STEP or OBJ, and transmits it to the service provider.
   Alternatively, many services also offer support with design or data preparation.
2. Data checking and optimization:
   The model is checked by the provider for printability, wall thicknesses, dimensional accuracy and potential weak points.
   Incorrect geometries are corrected or, if desired, adapted together with the customer.
3. Selection of process and material:
   Depending on requirements such as strength, surface quality, heat resistance, flexibility and color, the appropriate printing process and material are selected.
4. Printing process:
   The model is built up layer by layer - by melting, curing or sintering, depending on the process.
   The workpiece is created directly from the digital data set.
5. Post-processing:
   After printing, cleaning, de-powdering, support material removal, grinding, painting, polishing or heat treatment follow as required to optimize the surface and function.
6. Quality control and shipping:
   The finished component is verified, measured and, if necessary, tested before it is shipped to the customer.

This well-structured process ensures high quality and repeat accuracy, even for individual orders.
