3D printing technologies

Designing a curriculum for teaching 3D printing technology to school students can be both educational and practical. Below is a suggested curriculum outline for introducing students to the basics of 3D printing.

Grade Levels: 6-10

Objective: Introduce students to the principles of 3D printing, including design, modeling, printing techniques, and applications.

Week 1-2: Introduction to 3D Printing

  • What is 3D printing?
  • History and evolution of 3D printing technology
  • Types of 3D printing processes (FDM, SLA, SLS, etc.)
  • Overview of 3D printing materials (PLA, ABS, PETG, etc.)

Week 3-4: 3D Modeling Basics

  • Introduction to 3D modeling software (Tinkercad, SketchUp, Fusion 360, etc.)
  • Understanding basic 3D modeling concepts (shapes, extrusion, rotation)
  • Hands-on exercises to create simple 3D models

Week 5-6: Intermediate 3D Modeling Skills

  • Advanced features of 3D modeling software (boolean operations, fillets, chamfers)
  • Design principles for 3D printing (overhangs, support structures, tolerances)
  • Designing more complex 3D models (e.g., mechanical parts, figurines)

Week 7-8: Preparing Models for 3D Printing

  • Exporting models for 3D printing (STL file format)
  • Introduction to slicing software (Cura, PrusaSlicer, Simplify3D)
  • Optimizing print settings (layer height, infill density, print speed)
  • Understanding the role of support structures and rafts

Week 9-10: Hands-on 3D Printing

  • Introduction to 3D printers and their components (extruder, heated bed, build plate)
  • Basic operation and maintenance of 3D printers
  • Loading filament and calibrating print settings
  • Printing simple objects and troubleshooting common issues

Week 11-12: Advanced Applications and Projects

  • Exploring advanced 3D printing techniques (dual extrusion, multi-material printing)
  • Collaborative design and printing projects (e.g., creating prototypes, designing custom objects)
  • Ethical considerations and sustainability in 3D printing
  • Future trends and career opportunities in additive manufacturing


  • Evaluation of 3D models created by students
  • Quality of printed objects and adherence to design specifications
  • Participation in hands-on printing activities and projects
  • Quizzes and exams assessing theoretical knowledge.

Note: It’s essential to prioritize safety throughout the curriculum and provide adequate supervision during hands-on activities involving 3D printing equipment. Additionally, integrating real-world projects and applications can enhance students’ engagement and understanding of 3D printing concepts.
