3D Printer Course

Lesson 1 • Safety, Workspace, and Ethics

Covers ventilation, fire safety, material handling, and responsible use of shared designs. Establishes safe habits before any hands-on printing begins.

Lesson 2 • Real-World Applications and Industries

Surveys how prototyping, medical, aerospace, education, and consumer sectors use 3D printing. Motivates learners by connecting skills to tangible career and creative outcomes.

Lesson 3 • Core 3D Printing Technologies Overview

Compares FDM, SLA, SLS, and MSLA processes by mechanism, material, and output quality. Builds vocabulary for evaluating which technology suits a given task.

Lesson 4 • Anatomy of an FDM Printer

Identifies every major hardware component and its function within the print process. Provides the mechanical literacy needed for setup, calibration, and troubleshooting.

Lesson 1 • Core Modeling Concepts and Geometry

Teaches primitives, Boolean operations, extrusion, and lofting as building blocks of any model. Directly prepares students to construct printable geometry from scratch.

Lesson 2 • Introduction to CAD Software Options

Surveys Tinkercad, Fusion 360, and Blender relative to skill level and print intent. Guides learners to select the appropriate tool for their workflow.

Lesson 3 • Sourcing and Evaluating Existing Models

Navigates repositories like Printables and Thingiverse to find, assess, and legally use community models. Complements original design skills with efficient resource use.

Lesson 4 • File Formats and Export Preparation

Covers STL, OBJ, 3MF, and STEP formats, their trade-offs, and correct export settings. Ensures models transfer from CAD to slicer without data loss or errors.

Lesson 1 • G-Code Basics and Custom Scripts

Demystifies G-code structure and teaches start/end script customisation for automation. Empowers students to modify machine behaviour beyond slicer GUI limitations.

Lesson 2 • Support Structures and Placement

Configures automatic and manual supports for overhangs, bridges, and complex geometries. Reduces post-processing effort by generating only necessary support material.

Lesson 3 • Slicer Software Interface Navigation

Orients learners to PrusaSlicer and Cura layouts, toolbars, and viewport controls. Reduces friction so students focus on settings rather than interface confusion.

Lesson 4 • Temperature, Speed, and Flow Settings

Tunes hotend temperature, bed temperature, print speed, and extrusion multiplier per material. Directly links slicer parameters to print defect prevention covered in later chapters.

Lesson 5 • Infill Patterns and Density

Analyses grid, gyroid, honeycomb, and lightning infill patterns for strength and material use. Enables informed decisions that optimise part performance without waste.

Lesson 1 • ABS, ASA, and High-Temp Materials

Addresses warping, enclosure requirements, and post-processing for ABS and ASA. Prepares students for engineering-grade prints that withstand heat and UV exposure.

Lesson 2 • Specialty and Composite Filaments

Surveys wood-fill, carbon fibre, metal-fill, and glow-in-the-dark filaments with their nozzle and setting requirements. Expands creative and functional possibilities beyond standard materials.

Lesson 3 • PLA: The Beginner Standard

Covers PLA's print parameters, mechanical limits, biodegradability, and colour variety. Establishes a reliable baseline material before introducing more demanding filaments.

Lesson 4 • PETG: Strength and Flexibility Balance

Examines PETG's chemical resistance, layer adhesion, and stringing tendencies. Positions PETG as the go-to upgrade for functional parts requiring durability.

Lesson 1 • Routine Maintenance Schedule

Establishes lubrication, cleaning, and inspection intervals for rods, lead screws, and nozzles. Extends printer lifespan and prevents mid-print failures from neglected components.

Lesson 2 • Extruder and Flow Calibration

Calibrates E-steps, flow rate, and pressure advance to eliminate under- and over-extrusion. Ensures dimensional accuracy and clean surface finish on all prints.

Lesson 3 • Temperature and PID Tuning

Runs PID autotune for hotend and heated bed to stabilise thermal performance. Prevents temperature swings that cause inconsistent extrusion and layer bonding failures.

Lesson 4 • Unboxing and Initial Assembly

Guides step-by-step assembly of a kit-style FDM printer with torque and alignment checks. Builds mechanical confidence and prevents assembly errors that cause print failures.

Lesson 1 • Adhesion Failures and Warping

Identifies causes of bed adhesion loss, warping, and elephant foot, then applies targeted fixes. Connects bed levelling and material knowledge from prior chapters to real failure scenarios.

Lesson 2 • Layer Adhesion and Delamination

Addresses weak layer bonds caused by low temperature, fast speed, or insufficient cooling. Reinforces the relationship between slicer settings and structural integrity.

Lesson 3 • Dimensional Inaccuracy and Artifacts

Corrects ringing, ghosting, Z-banding, and dimensional drift through mechanical and slicer adjustments. Applies calibration knowledge to achieve dimensionally accurate functional parts.

Lesson 4 • Under-Extrusion and Clogs

Diagnoses partial clogs, grinding, and heat creep as sources of under-extrusion. Teaches cold pull, nozzle replacement, and PTFE inspection as corrective actions.

Lesson 1 • Hardware Inserts and Assembly

Installs heat-set inserts, magnets, and hardware into printed parts for functional assemblies. Elevates prints from prototypes to production-quality components.

Lesson 2 • Chemical Smoothing Methods

Covers acetone vapour smoothing for ABS and XTC-3D epoxy coating for PLA surfaces. Addresses safety protocols and ventilation requirements for chemical processes.

Lesson 3 • Support Removal and Cleanup

Demonstrates safe removal of supports and brims using pliers, flush cutters, and heat tools. Minimises surface damage and prepares parts for subsequent finishing steps.

Lesson 4 • Priming, Painting, and Coating

Applies filler primer, acrylic paints, and clear coats for durable, professional finishes. Connects surface preparation quality directly to paint adhesion and longevity.

Lesson 1 • Capstone Project: End-to-End Build

Students design, slice, print, and finish a self-defined functional object meeting specified criteria. Integrates every chapter's skills into a single documented deliverable.

Lesson 2 • Print Farm and Batch Production Basics

Introduces queue management, profile consistency, and quality control across multiple printers. Prepares students for small-scale production or maker-space management roles.

Lesson 3 • Multi-Material and Multi-Colour Printing

Configures dual-extrusion and filament-switching systems for colour and material combinations. Expands design possibilities while managing purge towers and wipe sequences.

Lesson 4 • Large-Format and Split-Part Printing

Strategies for printing objects exceeding build volume through splitting, keying, and bonding. Teaches orientation and seam placement to maintain structural integrity across joints.
