Which process is described as simple and robust?

Fused Deposition Modeling (FDM) is known for its simplicity and robustness, making it a popular choice in the realm of 3D printing. This process involves the extruding of melted thermoplastic material through a heated nozzle, which then forms layers to create a three-dimensional object.

One of the key features that contribute to the robustness of FDM is its ability to work with a variety of materials, including ABS, PLA, and PETG, which exhibit superb adhesion properties during the printing process. This adaptability makes it suitable for both prototyping and production, allowing for reliable and consistent results.

Additionally, FDM printers are generally more accessible and easier to operate compared to other 3D printing technologies. They often have simpler maintenance requirements and are less sensitive to environmental factors, such as humidity and temperature fluctuations. This simplicity translates to a wider range of users, from hobbyists to industrial professionals.

Comparatively, other processes like SLA, PolyJet, and Selective Laser Sintering have more complex operating principles, requiring more specialized knowledge, handling with caution due to materials used, and generally more extensive post-processing steps, which can detract from their robustness in a typical user environment. Therefore, the identification of FDM as a simple
