How Hard Is It to Design Something to 3D Print?

Designing something to 3D print is a bit more difficult than designing something for a two-dimensional printer. This is because 3D printing relies on virtual three-dimensional models that need to be created in CAD (Computer Aided Design) software before they can be printed out.

Designers need to consider the size, shape, and material of their object when creating the model, as well as how it will be supported during the printing process. The complexity of the design also affects the difficulty of creating a 3D printable model; some objects may require intricate details or delicate shapes that are difficult to recreate in software.

In addition to design considerations, 3D printing requires specialised hardware and software. A variety of 3D printers are available on the market with different capabilities and features, so designers must select one that is suitable for their project. Additionally, designers must make sure that the CAD software they use is compatible with their printer’s requirements and can support all of the features needed for their project.

Designers must also account for potential errors during printing. For example, if an object has too many overhangs or unsupported edges, it may collapse during printing. To prevent this from happening, designers must take into account how each layer of material will be laid down by the printer and adjust their designs accordingly.


Overall, designing something to 3D print can be quite challenging depending on its complexity and required features. The designer must consider how their model will be supported while being printed as well as selecting suitable hardware and software before they can begin creating it in a CAD program.
