Lesson 2 • History and Evolution of 3D Printing

Traces additive manufacturing from 1980s stereolithography to modern desktop printers. Provides context for why specific technologies dominate today's market.

Lesson 3 • Core Additive Manufacturing Principles

Explains layer-by-layer deposition logic and how digital models become physical objects. Connects slicing math to real-world print outcomes.

Lesson 4 • Anatomy of a 3D Printer

Identifies every major hardware component and its functional role in the print process. Builds vocabulary needed for troubleshooting and maintenance chapters.

Lesson 1 • Material Testing and Validation

Teaches tensile, layer adhesion, and dimensional accuracy testing to validate material performance. Connects test results to slicer parameter adjustments.

Lesson 2 • Engineering and High-Performance Filaments

Addresses Nylon, ASA, PC, and PEEK processing challenges and industrial use cases. Prepares learners for functional part production in demanding environments.

Lesson 3 • Standard Filaments: PLA, PETG, ABS

Covers print temperatures, bed adhesion, warping behaviour, and mechanical properties of the three most common filaments. Establishes baseline competency for everyday printing.

Lesson 4 • Polymer Fundamentals for 3D Printing

Introduces thermoplastic behaviour, glass transition temperature, and crystallinity as they affect printability. Provides the scientific basis for all material-specific settings.

Lesson 1 • Modelling Software Selection and Setup

Surveys parametric, sculpting, and CAD tools by use case and skill level. Learners configure a chosen tool for print-oriented workflows.

Lesson 2 • Introduction to 3D Modelling Concepts

Introduces mesh geometry, coordinate systems, and manifold solids as prerequisites for printable design. Connects modelling decisions directly to print success or failure.

Lesson 3 • Sourcing and Repairing Existing Models

Guides learners through model repositories, licensing considerations, and mesh repair workflows. Ensures downloaded files are print-ready before slicing.

Lesson 4 • Designing for Printability

Teaches wall thickness, overhang angles, bridging limits, and tolerance rules that govern successful prints. Applies design-for-manufacturing logic to additive processes.

Lesson 1 • Infill Patterns and Structural Settings

Analyses infill geometry, density, and shell count for strength, weight, and material efficiency. Matches infill strategy to functional part requirements.

Lesson 2 • Slicer Interface and Workflow

Maps the end-to-end slicer workflow from file import to G-code export. Establishes efficient habits for navigating slicer environments.

Lesson 3 • Layer and Quality Settings

Controls layer height, line width, and print speed to balance quality against print time. Learners predict visual and structural outcomes from parameter changes.

Lesson 4 • Advanced Slicer Features

Uses modifier meshes, variable layer height, and custom G-code injection for complex prints. Unlocks professional-level print optimisation techniques.

Lesson 1 • Bed Leveling and First Layer Mastery

Covers manual tramming, automatic mesh levelling, and Z-offset tuning for perfect first-layer adhesion. First-layer quality is the single greatest predictor of print success.

Lesson 2 • Print Monitoring and Intervention

Establishes protocols for monitoring active prints, detecting failures early, and intervening safely. Reduces wasted material and time from undetected failures.

Lesson 3 • Extruder and Flow Calibration

Calibrates E-steps, flow rate, and pressure advance to ensure accurate material deposition. Eliminates under- and over-extrusion as root causes of defects.

Lesson 4 • Temperature and Speed Optimisation

Uses temperature towers and speed benchmarks to find optimal print parameters per material. Balances thermal performance with mechanical output quality.

Lesson 1 • Quality Inspection and Acceptance Criteria

Establishes measurable quality standards using callipers, visual inspection, and functional testing. Creates repeatable acceptance criteria for professional print output.

Lesson 2 • Adhesion and Warping Failures

Diagnoses first-layer detachment, warping, and elephant foot through thermal and adhesion analysis. Applies targeted fixes without changing unrelated parameters.

Lesson 3 • Extrusion and Flow Defects

Identifies under-extrusion, over-extrusion, stringing, and blobs through visual and mechanical diagnosis. Links each defect to specific hardware or slicer root causes.

Lesson 4 • Geometric and Dimensional Defects

Addresses layer shifting, ghosting, elephant foot, and dimensional inaccuracy through motion and calibration analysis. Restores dimensional fidelity to functional parts.

Lesson 1 • Support Removal and Surface Preparation

Covers safe support removal tools, techniques, and surface preparation for subsequent finishing steps. Prevents part damage during the most physically demanding post-processing stage.

Lesson 2 • Chemical Smoothing and Bonding

Applies acetone vapour smoothing for ABS, resin coating for PLA, and solvent bonding for assemblies. Achieves injection-moulded surface quality on printed parts.

Lesson 3 • Functional Enhancement Techniques

Integrates heat-set inserts, embedded magnets, and hardware inserts to add mechanical functionality. Extends the engineering utility of printed parts beyond raw plastic.

Lesson 4 • Resin Print Post-Processing

Covers IPA washing, UV curing parameters, and support removal specific to SLA and MSLA prints. Ensures full cure and safe handling of photopolymer parts.

Lesson 1 • Capstone Project Planning and Review

Structures a complete project from brief to finished deliverable with peer review and documented outcomes. Consolidates all course competencies into a single evaluated artefact.

Lesson 2 • Large Format and Long Print Management

Addresses part splitting, print farm scheduling, and failure recovery for prints exceeding standard build volumes. Manages risk and time for high-investment print jobs.

Lesson 3 • Multi-Material and Multi-Colour Printing

Configures dual-extrusion and filament-change workflows for multi-material and multi-colour outputs. Expands design possibilities for complex functional and aesthetic parts.

Lesson 4 • Multi-Part Assembly Design Strategy

Designs interlocking, fastened, and press-fit assemblies that exploit printing strengths while compensating for limitations. Produces functional multi-component products.
