Creating 3D modeling drawings is based on drawing in digital object processing programs such as Maya, Zbrush, Google SketchUp, Photoshop, etc. In addition to these programs, it is possible to scan a real object using a 3D scanner, which converts a real object into a three-dimensional .stl file, or primarily by hand drawing. Software development is most often used since scanners are inaccessible due to the price. Programs allow us to process every detail of an object, its edges, and the details that characterize it. If you are not experienced in using drawing programs, you have a wide range of tutorials on the Internet for their use.
Before starting to draw in a program, it is most practical for more complex models to make a few hand sketches so that the final model can be transferred to the program later as precisely as possible.
After selecting a 3D modeling program, it is necessary to plan some items before starting the design. The two items that must be considered are the thickness of the walls when printing and the details. These measurements are based on the type of printer and materials used. The minimum wall thickness of an object is how thin the thinnest part of an object is. The object must be thin enough to be able to print from a specific material. Consideration must also be given to how thin the parts are to support the main object being printed. For example, if a wine glass were made, and the wall thickness was 1mm, the structure would not be strong enough to withstand the larger structure above. But if the thickness is changed to 5mm, the structure would be stronger.
In animation software, your model exists in a world without gravity and physics. In order for the model to exist in the physical world, you must consider the characteristics of the filament. To better understand the strength and weaknesses of the material, watching the printer in action can be helpful. Take time to see how the model will be distributed. If you want the model to stand on its own, make sure that the bottom of the model has weight. Adjust the size of the model to fit the dimensions of the printer. The level of detail must also be taken into account because 3D printers can create detailed objects up to a certain level. Like regular printers, they do not have an unlimited resolution. Research must be conducted to know the capabilities of a particular 3D printer. Moving parts must be carefully spaced so as not to interfere with the printing process accidentally. Everything is based on the material that will be used during printing. Different materials have support for different wall thicknesses and levels of detail.
In addition to freelance model design, completed print-ready objects can be found on Pinshape, Thingiverse, and many more. On them, you can find models that are free to download, as well as complex objects that are charged to download. In commercial circles, the creation of models by the scanning and 3D printing of the human model or MiniMe is gaining in popularity. After creating a 3D model in one of the available programs, it is necessary to save the model in a convenient format for later release. The most commonly supported .stl file is available in all 3D modeling programs.
