Manufacturing Plan: Cut Lists, Hardware, and STL Exports

1. From Model to Plan: What We Need

A complete manufacturing plan tells you everything you need to know to build your design. For our shelf project, this plan has three key parts:

1. A Cut List: The dimensions for the wooden shelf.
2. A Hardware List: The type and quantity of screws needed for assembly.
3. An STL File: A 3D printable file for the brackets.

We will generate all of these directly from the Fusion 360 model you created in the previous lesson.

2. Creating a Parts List and Cut List

For physical items like wood and hardware, engineers and woodworkers use a Bill of Materials (BOM) or a Parts List. In Fusion 360, the most robust way to create this is within the Drawing workspace. It can automatically generate a table of all components in your design.

To make this list useful, we first need to ensure our components contain the right information.

Step 1: Add Properties to Your Components

Open the shelf design you saved from the last lesson.

1. In the Browser, find your Shelf component. Right-click it and select Properties.
   • In the Description field, enter the stock material you would use, for example, 18mm Plywood or 1x6 Pine Board.
   • Click OK.
2. Now, right-click the Shelf component again and select Physical Material.
   • In the dialog, find a suitable Wood material (e.g., Pine, Oak, or just the generic Wood) and drag it onto the Shelf component in the Browser or viewport.
3. Repeat this process for the Bracket component.
   • Properties: Add a Description like 3D Print.
   • Physical Material: Assign a plastic, such as ABS Plastic or PETG Plastic. This helps differentiate parts in the list.

These properties will now automatically populate our parts list.

Step 2: Generate the Parts List

The following video provides an excellent walkthrough of creating a parts list in the Drawing workspace. We'll follow this process for our shelf assembly.

Step 3: Apply the Workflow to Your Shelf

Now, let's apply those steps to your file:

1. With your assembly open, go to File > New Drawing > From Design.
2. In the dialog, ensure Full Assembly is selected. For sheet size, A4 or 8.5 x 11 (Letter) is fine. Click OK.
3. Place a base view of your assembly onto the sheet. An Isometric view is often best for this purpose.
4. Go to the toolbar and select Tables > Table (or just Table depending on your UI version).
5. Place the table in a corner of the drawing.

Fusion 360 will automatically generate a parts list. It should show one Shelf and two Bracket components. Double-click the table to edit it and customize the columns as shown in the video. A good setup includes:

• Item
• QTY
• Part Name
• Description
• Material

Step 4: The Hardware List

You'll notice our screws are missing from the list. This is because we only modeled holes for them, not the screws themselves. For complex projects, you would model or import standard hardware from a library like McMaster-Carr (a topic we'll cover in the capstone project).

For this project, we can simply add a manual note.

1. In the Drawing workspace toolbar, select Text.
2. Create a text box on your drawing.
3. Add your hardware list, for example:

   Hardware Required:

   • 4x Countersunk wood screws for wall mounting (e.g., #8 x 1.5")
   • 2x Pan-head wood screws to secure shelf (e.g., #8 x 0.75")

Step 5: Finalize the Plan

You now have a drawing sheet that contains a 3D view of your project, an itemized parts list, and a hardware list. This is your manufacturing document. You can save it within Fusion 360 and also export it as a PDF via the Export > Export PDF option for easy printing and viewing in your workshop.

3. Exporting the STL File for 3D Printing

With the plan for the wood and hardware complete, the final step is to generate the file for your 3D printer. The standard file format for this is STL (stereolithography), which describes the model's surface geometry as a mesh of triangles.

The video below clearly explains how to export an STL file from Fusion 360.

Now, let's export the Bracket component:

1. Return to your main Design workspace tab.
2. In the Browser, right-click on the Bracket component.
3. Select Save as Mesh. (This is a direct way to the same dialog shown in the video).
4. In the dialog box:
   • Format: STL (Binary)
   • Unit Type: Millimeter
   • Refinement: High. As the video mentions, modern computers and slicers handle high-polygon files easily, and this ensures your curved surfaces are smooth.
5. Click OK and save the STL file to your computer.

Because you created the second bracket using the Copy and Paste commands, it is an identical instance. Therefore, you only need to export one STL file and simply print it twice.

You now have the file ready to be imported into slicer software like Bambu Studio, which we'll cover in a future module.

Conclusion

Excellent work. You have successfully taken a complete 3D assembly and generated a full manufacturing plan. This is the workflow that turns digital ideas into physical realities.

Key Takeaways:

• A comprehensive manufacturing plan includes drawings for traditional fabrication (like woodworking) and digital files for modern methods (like 3D printing).
• The Drawing workspace in Fusion 360 is a powerful tool for creating parts lists, which are automatically generated from the components in your model.
• Populating component Properties (like Description and Physical Material) is key to creating a rich, informative Bill of Materials.
• STL files are the standard for 3D printing and are exported from Fusion 360 using the Save as Mesh or 3D Print commands.

You have now completed the module on designing with mixed materials, culminating in this complete project plan. You're ready to tackle something bigger. In our next module, we will begin your capstone project: Designing and Modeling the PC-Integrated Gaming Desk. We will start by defining its functional requirements and constraints, laying the groundwork for the ambitious build you're aiming for. The skills you've consolidated here will be invaluable.
