Explains PID control loops for hotend and heated bed temperature stability. Students run auto-tune routines and verify thermal performance under load.
Lesson 2 • Mechanical Assembly and Inspection
Covers frame squaring, belt tensioning, and axis alignment for Cartesian and CoreXY printers. Proper assembly prevents compounding errors in later calibration steps.
Lesson 3 • Extruder and Flow Calibration
Teaches E-step calibration, flow rate multiplier tuning, and pressure advance setup. Accurate extrusion is the foundation of dimensional precision and surface quality.
Lesson 4 • Bed Leveling Techniques
Compares manual tramming, mesh bed leveling, and automatic probes like BLTouch and CR Touch. Students achieve a consistent first layer across the full print surface.
Lesson 5 • Input Shaping and Resonance Compensation
Introduces accelerometer-based resonance measurement and input shaping algorithms. Students eliminate ringing artifacts and unlock higher print speeds safely.
Chapter 3HideHide detailsSee detailsSlicer Software Mastery
Slicer Software Mastery
Lesson 1 • Slicer Interface and Navigation
Orients students to PrusaSlicer, Cura, and Bambu Studio layouts. Establishes efficient navigation habits before introducing complex parameter tuning.
Lesson 2 • Advanced Slicer Features
Explores modifier meshes, multi-material purge towers, and custom G-code injection. Students unlock slicer capabilities for complex, production-grade prints.
Lesson 3 • Temperature, Speed, and Cooling Profiles
Links hotend temperature, print speed, and part cooling fan curves to print quality outcomes. Students build material-specific profiles from scratch.
Lesson 4 • Support Structures and Bridging
Covers automatic and manual support placement, interface layers, and bridging parameters. Students minimise support waste while ensuring overhang success.
Lesson 5 • Layer, Infill, and Wall Settings
Explains how layer height, infill density, pattern, and wall count affect strength and print time. Students balance quality and efficiency for each job type.
Chapter 4HideHide detailsSee detailsMaterials Science for 3D Printing
Materials Science for 3D Printing
Lesson 1 • Moisture, Storage, and Drying Protocols
Explains hygroscopic degradation and its effect on print quality. Students implement drying schedules and storage systems to maintain material integrity.
Lesson 2 • Resin Materials for SLA and MSLA
Distinguishes standard, ABS-like, flexible, and castable resins by chemistry and cure behaviour. Connects resin choice to exposure settings and post-cure requirements.
Lesson 3 • Composite and Specialty Filaments
Covers carbon fibre, wood-fill, metal-fill, and flexible TPU materials. Students adjust hardware and settings to handle abrasive and exotic blends.
Lesson 4 • Material Testing and Qualification
Introduces tensile, layer adhesion, and dimensional accuracy tests for printed specimens. Students validate new material batches before production use.
Lesson 5 • Polymer Filament Fundamentals
Examines PLA, PETG, ABS, ASA, and Nylon at the molecular level. Links polymer structure to print behaviour, strength, and temperature resistance.
