Why does 3D printing take so much time?

3D printing can indeed take a considerable amount of time, and there are several reasons why the process can be time-consuming:

  • Layer-by-layer construction: 3D printers create objects by building them up layer by layer. Each layer has to be printed individually and depending on the height of the printed object this can take a lot of time.

  • Print Speed: Print speed significantly affects print time. Slower print speeds can result in better print quality, but are more time-consuming.

  • Design complexity: Complex designs or models with a lot of details require more time to print each layer. Layer height: The layer height, i.e. the thickness of each printed layer, also influences the printing time. Lower layer heights result in more detailed prints but require more time.

  • Fill and Infill: The percentage of internal fill or infill of the printed object affects print time. Higher infill values mean more material and more time.

  • Printing material: Different materials have different printing parameters, and some require slower printing speeds or higher temperatures, which may affect printing time.

  • Print quality settings: Higher print quality settings, such as finer layer heights or more detailed print patterns, result in longer print times.

  • Support Structures: If a model requires support structures to support overhanging parts, this increases printing time as these structures also need to be built up layer by layer.

  • Printer performance: The performance and speed of the 3D printer itself also plays a role. High-quality printers with fast movements can speed up the printing process.

  • Cooling times: After each layer is printed, the material needs time to cool before the next layer is printed. Print time is often a compromise between speed and print quality. The exact duration depends on the factors mentioned above and can vary from print to print.
