# Overview What the area is for, equipment at a glance and who the Area Champion is. # Digital Fabrication Overview Digital Fabrication covers the machines that turn a computer design into a physical part: **3D printers**, the **laser cutter** and **CNC**. The 3D printers live in the print lab; the laser and CNC are in the laser/CNC shop. 3D printing and laser cutting are **self-serve once you have been trained**. ## Equipment at a glance The current list of equipment, with locations and which machines need training, is in **Atlas**: https://atlas.waukeshamakers.com. The 3D printers with maintenance pages in this book are: - Original Prusa MK4 - Original Prusa i3 MK3S+ - Bambu Lab X1 Carbon with AMS 2 Pro and AMS - Anycubic Kobra 2 Max ## Pages in this book - **Digital Fabrication: Fusion 360 Cheat Sheet**: the basics of designing parts in Fusion 360 - **Digital Fabrication: Laser Cutter** - **Digital Fabrication: Laser-Safe and Prohibited Materials** - Maintenance checklists for each 3D printer in the **Maintenance** chapter ## Before you work here - **Get trained** on each machine before you use it. See **Training and Certification: How Certification Works**, and check your certifications in Journeyman at https://journeyman.waukeshamakers.com. - **Never leave the laser unattended** while it is running. - **Only cut approved materials** on the laser. See **Digital Fabrication: Laser-Safe and Prohibited Materials**. - **Fumes.** See **Shop Safety: Air Quality**. - **Inspect before use.** See **Training and Certification: Pre-Use Inspection**. If a printer or the laser is not working right, tag it and report it: see **Shop Safety: Tagging a Tool Out of Service and Reporting It**.

To be confirmed: whether members supply their own filament and laser stock or the shop provides some, and how members send jobs to the printers. See also **Facility Operations: Consumables**.

## Learning to design New to 3D design? The **Fusion 360 Basics** class walks you through your first model. The class outline and handout are in **Classes and Instructors: Fusion 360 Basics**, and the cheat sheet is in this book. ## Area Champion

To be confirmed: who the Digital Fabrication Area Champion is and how to reach them. See **Volunteer Runbooks: Area Champions** for what Area Champions do.

# Fusion 360 Cheat Sheet A quick reference for designing parts in Autodesk Fusion 360. This is the handout from the **Fusion 360 Basics** class; see **Classes and Instructors: Fusion 360 Basics** for the class itself. ## The core workflow This is the process you will repeat for almost everything you build: 1. **Sketch** a 2D shape on a plane or face. 2. **Extrude** it into 3D (add material). 3. **Sketch** on a face of your 3D object. 4. **Cut** to remove material (extrude inward). 5. **Fillet** to round edges and finish. 6. Repeat steps 3 to 5 to add detail. ## Keyboard shortcuts | Shortcut | Action | |---|---| | **S** | Search bar (find any tool by name) | | **L** | Line | | **C** | Circle | | **R** | Rectangle | | **D** | Sketch Dimension | | **E** | Extrude | | **F** | Fillet | | **Q** | Push/Pull | | **M** | Move/Copy | | **Ctrl+Z / Cmd+Z** | Undo | **Tip:** press **S** and type the name of any tool. It is the fastest way to find anything. ## Mouse navigation | Action | Control | |---|---| | **Orbit** | Middle mouse button | | **Pan** | Shift + middle mouse button | | **Zoom** | Scroll wheel | | **Reset view** | Click the house icon on the view cube (top right) | ## Practice project: phone stand The class project. Dimensions are included so you can rebuild it at home. ### Step 1: Base 1. **Create Sketch** on the XZ plane (the floor). 2. Draw a **Rectangle**: 70 mm x 80 mm. 3. **Finish Sketch**. 4. **Extrude** (Symmetric): 10 mm. ### Step 2: Back support 1. **Create Sketch** on the back face (the 70 mm x 10 mm face). 2. Draw a **Rectangle** from the top-left corner: 70 mm wide x 60 mm tall. 3. **Finish Sketch**. 4. **Extrude**: 10 mm (away from the base). ### Step 3: Phone slot 1. **Create Sketch** on the top face of the base. 2. Draw a **Rectangle**: 50 mm x 4 mm, positioned 5 mm from the back wall. 3. **Finish Sketch**. 4. **Extrude** as **Cut**: -8 mm (leaves a 2 mm floor). ### Step 4: Fillet 1. Select **Fillet** (or press **F**). 2. Click the top edges of the back support; radius **5 mm**. 3. Optionally fillet the bottom edges of the base: **3 mm**. ### Dimensions reference | Feature | Size | |---|---| | Base | 70 x 80 x 10 mm | | Back support | 70 x 60 x 10 mm | | Phone slot | 50 x 4 mm, 8 mm deep cut | | Fillets | 5 mm (top), 3 mm (bottom) | ## Stuck? Check here first | Problem | Fix | |---|---| | Can't see my sketch | Click the **Home** icon on the view cube | | Extrude is grayed out | Click **Finish Sketch** first | | Extrude didn't cut | Undo, redo the extrude, and change Operation to **Cut** | | Sketch lines are still blue | Add dimensions to fully constrain the sketch (it still works if you don't) | | Can't select a face | Zoom in and hover until the *face* highlights, not an edge | | Model disappeared | Check the eye icons in the Browser panel (left side) | ## What to learn next 1. **Components:** organizing multi-part models. 2. **User Parameters:** named variables for dimensions. 3. **Patterns:** repeating features in circles or grids. 4. **STL Export:** File, Export, STL, so you can 3D print your design. ## Resources - **Product Design Online** (YouTube): beginner-friendly Fusion 360 tutorials. - **r/Fusion360**: a Reddit community for questions and inspiration. - **The makerspace:** come in and practice, and ask in #general on Discord if you get stuck.
