What is print-in-place in 3D printing?

Print-in-place means 3D models with movable parts, all in a single print. Unlike traditional 3D printing models, where each part is printed separately and then assembled, print-in-place design allows users to print as one cohesive unit without the need for post-print assembly.

The core idea behind print-in-place is to eliminate the assembly process, which is achieved by designing the 3D model in such a way that it includes tiny gaps or clearances between the moving parts. These clearances are precisely calibrated to ensure that once the printing is done, the parts can move or articulate as intended right off the print bed.

Print-in-place designs reduce the overall time from design to functional part, as there is no need for post-processing or assembly. It also enables the creation of complex mechanisms such as gears, hinges, and joints, all within a single print.

So, today, we find a list of great print-in-place 3D models for you! Let's print and have fun!
