🛠️ Lesson: Complete a Print-to-Finish Project

🎯 Focus: Bring together everything you’ve learned—from modeling to slicing, printing, post-processing, and presentation—by completing a full 3D printing project from start to finish.

✅ Lesson Summary

This capstone-style lesson gives students the chance to apply every step of the 3D printing process in a guided or self-directed project. From concept to final presentation, learners will select a model or design their own, prepare it for printing, carry out the print, and finish the object for final use or display. The goal is to experience a realistic 3D printing workflow and gain confidence in handling a project end-to-end.

🎓 Learning Objectives

By the end of this lesson, students will:

  1. Apply design, slicing, and printing knowledge to a complete project

  2. Practice post-processing techniques such as support removal and surface finishing

  3. Troubleshoot and document problems during the printing workflow

  4. Prepare and present a finalized part with visual and written documentation

📘 Lesson Content

🔧 1. Step 1: Choose Your Project Type

Choose one of the following (or submit your own idea for approval):

  • Functional Object (e.g., phone stand, tool holder, cable organizer)

  • Artistic Print (e.g., miniature, decorative sculpture)

  • Prototype Component (e.g., part for a larger build or repair)

  • Educational Model (e.g., anatomy piece, math visual aid)

  • Customized Gift (e.g., name plate, personalized keychain)

Note: Students may download an existing STL or model their own in FreeCAD, Tinkercad, or Fusion 360.

🖥️ 2. Step 2: Slice and Prepare the Print

Open your slicer of choice (e.g., Orca Slicer, Cura, Chitubox) and set up the following:

  • Layer height

  • Supports (if necessary)

  • Infill density and pattern

  • Shells/wall thickness

  • Print speed and temperature

  • G-code preview to inspect critical layers

Export your final G-code and prepare your printer.

🖨️ 3. Step 3: Execute the Print

  • Load your filament or resin

  • Perform printer calibration (bed leveling, Z-offset check, extruder priming)

  • Monitor the print’s first few layers

  • Take time-lapse photos if possible

If errors occur (warping, stringing, layer shift), pause and troubleshoot using the guides from Module 6.

🧼 4. Step 4: Post-Processing

Once your print is complete:

  • Remove supports using pliers, cutters, or flush tools

  • Sand rough edges with progressive grit sandpaper

  • (Optional) Apply primer or paint

  • Photograph the finished object with good lighting

📋 5. Step 5: Document the Workflow

Create a simple project report including:

  • 1–2 sentences describing the purpose of the print

  • Screenshots or photos of:

    • Your model or STL source

    • Your slicing settings

    • The printing process

    • The final result (front/back/angled photos)

  • 1 paragraph summarizing:

    • What worked well

    • What you’d improve next time

    • Materials used and estimated cost

🧠 Summary

This final project is your opportunity to prove you can take a concept from idea to finished physical object. By completing a print-to-finish workflow, you’re not just building something—you’re demonstrating technical competency, creative problem-solving, and an understanding of what it takes to succeed in the world of 3D printing.

📂 Assignment

Submit the following:

  • A finished object photo

  • Your slicer project file or screenshot of your slicing settings

  • A short PDF or slide deck (up to 5 slides or 1 page) describing your process and results
