Cutting and Aligning 3D Printed Models Like a Pro

In the world of 3D printing, creating models larger than the printing volume can be quite a challenge. One effective solution is to cut the model into smaller, printable pieces, which can later be assembled. While basic cuts along the Z-axis can be executed directly in Slic3r, more complex cuts might require additional tools like Meshmixer. Let's delve into the process of cutting and aligning 3D printed models to achieve seamless results.

Simplifying Cuts with Slic3r

When using Slic3r for cutting models, the process is relatively straightforward. By specifying the height at which the model will be cut and potentially rotating the bottom part upside down, you can easily create separate pieces. However, the limitation lies in the ability to define cuts only along the Z-axis, which may lead to unwanted parts being severed.

Overcoming Challenges with Meshmixer

To tackle intricate cuts and avoid unintentional separation of model components, Meshmixer comes to the rescue. This versatile tool offers more flexibility in cutting models and aligning them accurately.

Basic Plane Cut in Meshmixer:
- Navigate to Edit > Plane Cut.
- Define a cutting plane by holding down the left mouse button.
- Opt for the Slice cut type to retain all parts of the model.
- Confirm the cut by hitting the Accept button.
Separating Model Shells:
- Even after the cut, the model may appear as one piece.
- To create individual models, select Edit > Separate Shells.
Refining Cut Areas:
- Use the Select tool to specify a particular area for the cut.
- Everything outside the selection will remain intact when the cut is applied.

Enhancing Assembly with Aligning Pins

Effective alignment is crucial for seamless assembly of the printed parts. Adding aligning pins facilitates easy and accurate joining of components.

Open the Objects browser and hide one part of the cut model.
Access the Meshmix menu and introduce a primitive (like a cylinder) to the cut plane.
Adjust the primitive's size and position using the provided gizmo.
Switch to Create New Object mode and finalize the placement.
Duplicate the primitive to ensure sufficient aligning pins.

With the aligning pins in place, exporting each model as an STL file becomes a breeze. The pins enable the parts to interlock effortlessly, eliminating the need for excessive glue during assembly.

Recap and Ready for Print!

By mastering the art of cutting and aligning 3D printed models, you can take your creations to the next level. From seamless cuts with Meshmixer to strategic placement of aligning pins, every step plays a vital role in the printing and assembly process. So, go ahead, experiment with different cutting techniques, and watch your 3D creations come to life effortlessly.
