3D modeling can be complicated. Different software is used, different materials are used, and different printing technologies are used. It's normal to feel confused and sometimes it can be difficult to create a 3D model that is perfect for 3D printing.
We have compiled a list of the top mistakes when turning a 3D model into a 3D printed model.
1. Every printing material is unique. Materials may be strong or weak, flexible or firm, smooth or rough or heavy or light. An object should be optimized for a particular material. You can also get help from the 3D Designer who can work on the best 3D models & product design from https://vizframe.com/3d-model-library.
If you decide to print your 3D model using Steel, you will need to consider specific material-related design considerations such as supporting overhanging pieces, strengthening elements that stick out, rounding corners, and so on.
2. Not only are the chemical properties of printing materials different but so are the technologies used to print each material. Interlocking parts is the best example. You can print interlocking pieces in ABS, Polyamide, or Alumide materials, but not in Gold, Silver, or Bronze. This is due to the technology used to print each material.
Fused Deposition Modeling is used for ABS. It uses a nozzle with extra material support. Laser Sintering is used for Polyamide, Alumide, and Polypropylene. Lost wax casting is used for precious metals. This 3D print is in wax. Stereolithography, which uses liquid polymer-based, can be used for Resins.
3.Although you can find information on the wall thickness in the guidelines, it is worth mentioning this again. Wall thickness problems are the main reason why 3D models cannot be printed. Sometimes, the wall thickness is too thin.
Walls too thin can make parts of the model impossible to print or fragile and may cause them to break. Walls that are too thick can cause internal stress, which could lead to the item cracking or even breaking.
