How Do You Design Something to 3D Print?

Designing something for 3D printing involves many considerations. It is important to have a clear idea of the function and purpose of the object, as well as its size and any other specifications that must be taken into account. Additionally, an understanding of the properties of the material being used and its limitations is necessary.

Before beginning to design an object for 3D printing, it is important to consider the type of printer that will be used. Different types of printers use different methods and materials, so it is essential to choose the right one for your project.

The cost, speed, accuracy, and resolution should all be taken into account when selecting a printer. Additionally, certain types of printers may be better suited for certain materials or specific objects.

Once you have chosen a printer and material for your project, you can begin designing the object. It is best to start with a rough sketch or concept art before creating 3D models in CAD software.

This allows you to brainstorm ideas without getting bogged down in technical details. Once you have a basic idea of what you want to create, you can begin modeling in CAD software such as Fusion 360 or Solidworks.

When modeling in CAD software, it is important to keep in mind how the object will be printed in order to achieve the desired result. The surfaces should be designed using smooth curves so that they print correctly; sharp edges may cause problems when printing due to lack of support or warping from heat buildup during printing. Additionally, it is important to design parts with appropriate overhangs and supports so they are structurally sound once printed.

It is also necessary to consider post-printing processes such as sanding or painting before designing an object for 3D printing. Many objects need additional finishing after being printed in order for them to look their best; this includes smoothing out any remaining sharp edges or imperfections on the surface with sandpaper or filler material before painting them with primer and paint if desired.


Designing something for 3D printing requires careful consideration of many different factors including the type of printer being used, material properties and limitations, surface curvature design principles, and post-printing processes such as sanding and painting. With careful planning and attention to detail it is possible to create stunning 3D printed objects with excellent results!
