Combining CNC milling with 3D printing offers creators the flexibility to produce complex designs with precision and efficiency. Carbide Create, a popular CAD/CAM software, provides an intuitive platform for CNC workflows. While traditionally used for CNC milling, Carbide Create can be adapted to complement 3D printing processes. This guide explains how to set up and execute a CNC-assisted 3D printing project using Carbide Create.
Understanding CNC and 3D Printing Integration
CNC (Computer Numerical Control) milling removes material from a solid block, while 3D printing builds objects layer by layer. Integrating these technologies allows:
- Enhanced precision for detailed designs.
- Combined subtractive and additive manufacturing for hybrid workflows.
- Use of robust materials that may not be compatible with standard 3D printers.
Carbide Create simplifies CNC operations, making it a powerful tool for preparing 3D printing-enhanced projects.
Tools and Materials Needed
Tools:
- CNC machine compatible with Carbide Create (e.g., Shapeoko, Nomad series).
- 3D printer (FDM or SLA).
- Computer with Carbide Create installed.
- End mills (for CNC cutting).
Materials:
- Material block (wood, aluminum, plastic, etc.) for CNC.
- Filament for 3D printing (PLA, PETG, or ABS).
- Adhesive (if needed for assembly).
- Sandpaper or finishing tools.
Step-by-Step Process
Step 1: Plan Your Design
1.1. Choose Your Project Type
- Hybrid Design: Part of the object is milled using CNC, and another part is 3D printed.
- CNC-Assisted 3D Print: CNC prepares the base or features to complement a 3D-printed component.
1.2. Sketch the Design
Use CAD software (e.g., Carbide Create) to sketch a base model. Plan which parts will be milled and which will be 3D printed.
Step 2: Design in Carbide Create
2.1. Import or Create Your Design
- Launch Carbide Create.
- Start a new project and set the workspace dimensions.
- Import existing SVG or DXF files, or sketch directly within the software.
2.2. Define Toolpaths
- Use the “Contour” tool to create paths for cutting.
- Specify cut depth and type (e.g., pocket or profile).
- Assign tool parameters based on the material and tool diameter.
2.3. Simulate the Toolpath
- Preview the toolpaths to ensure the design is accurate.
- Adjust settings for optimal material removal and surface finish.
2.4. Export G-Code
Save the G-code file for CNC machining. Ensure compatibility with your CNC machine’s control software.
Step 3: CNC Milling
3.1. Prepare the Machine
- Secure the material block on the CNC bed using clamps or a vacuum table.
- Install the appropriate end mill.
- Zero the machine to the material’s origin.
3.2. Execute the Milling
- Load the G-code into the CNC control software.
- Start the machining process and monitor progress.
- Remove the material block after completion and clean up any debris.
Step 4: 3D Printing
4.1. Prepare the 3D Print Model
- Design or modify the 3D model to complement the CNC-milled component.
- Export the 3D model as an STL file.
4.2. Slice the Model
- Import the STL file into slicing software (e.g., Cura or PrusaSlicer).
- Adjust settings such as layer height, infill, and supports.
- Generate the G-code for 3D printing.
4.3. Print the Component
- Load the filament into the 3D printer.
- Start the print and monitor for errors.
- Remove the finished print and perform post-processing as needed.
Step 5: Assemble the Parts
5.1. Fit and Test
- Test-fit the 3D-printed part with the CNC-milled component.
- Sand or trim parts for a precise fit.
5.2. Secure the Assembly
- Use adhesive, screws, or other fasteners to combine the components.
- Finish with sanding, painting, or polishing as desired.
Tips for Success
- Use Accurate Dimensions: Ensure the 3D-printed and CNC-milled components align perfectly by double-checking measurements.
- Select Appropriate Materials: Choose materials that complement each other and suit the project’s requirements.
- Simulate Before Milling: Carbide Create’s simulation tools can help prevent costly errors.
- Optimize CNC Speeds: Use the correct feed and speed settings for clean cuts.
- Test Fit Frequently: Test components during assembly to avoid misalignments.
