3D printing with printer training

Lesson 1 • Safety and Workspace Setup

Lesson 2 • What Is Additive Manufacturing

Defines additive manufacturing and contrasts it with subtractive methods. Grounds students in the core concept before exploring specific technologies.

Lesson 3 • Key Components of a 3D Printer

Identifies mechanical, electrical, and software components common to desktop printers. Builds vocabulary needed for setup and troubleshooting chapters.

Lesson 4 • Essential 3D Printing Terminology

Defines layer height, infill, supports, and other critical terms. Ensures students communicate accurately throughout the course.

Lesson 1 • Hotend and Nozzle Systems

Details heat break, heater block, thermistor, and nozzle materials. Students select correct nozzles for specific filament types covered later.

Lesson 2 • Build Plates and Bed Systems

Covers glass, PEI, and flexible magnetic bed surfaces and their adhesion properties. Students match bed surface to material requirements.

Lesson 3 • Motion Systems and Kinematics

Explains Cartesian, CoreXY, and delta motion architectures. Students predict how kinematic choice affects print quality and speed.

Lesson 4 • Extruder Systems In Depth

Differentiates direct drive and Bowden extruder setups and their trade-offs. Directly impacts filament control decisions made in later chapters.

Lesson 1 • First Print Validation

Executes a calibration cube and first-layer test to confirm all settings. Students diagnose and correct issues before moving to slicing.

Lesson 2 • PID Tuning and Temperature Stability

Runs PID autotune for hotend and heated bed to eliminate temperature fluctuations. Stable temperatures are prerequisite for consistent print quality.

Lesson 3 • Unboxing and Initial Assembly

Guides systematic unboxing, hardware inspection, and assembly steps. Prevents common assembly errors that cause print failures later.

Lesson 4 • Automatic Bed Leveling Setup

Configures BLTouch, CR Touch, and inductive probes for mesh bed leveling. Builds on manual leveling understanding to automate compensation.

Lesson 5 • Extruder and Flow Calibration

Calibrates E-steps and flow rate to ensure accurate filament extrusion. Directly determines dimensional accuracy of all future prints.

Lesson 1 • Speed, Temperature, and Cooling

Tunes print speed, hotend temperature, and part cooling fan for each material. Connects slicer settings directly to print defect prevention.

Lesson 2 • Layer and Quality Settings

Controls layer height, line width, and wall count to balance quality and print time. Students make informed trade-offs for each print job.

Lesson 3 • Infill Strategies and Patterns

Explores infill density, pattern types, and their effect on strength and weight. Students select infill for functional vs. aesthetic prints.

Lesson 4 • Advanced Slicer Features

Uses pause at layer, color change, and custom G-code injection for complex prints. Prepares students for multi-material and specialty print workflows.

Lesson 5 • Support Generation and Optimization

Configures automatic and manual supports for overhangs and bridges. Reduces post-processing effort and surface damage from poor support placement.

Lesson 1 • PLA: The Beginner Standard

Covers PLA composition, print settings, and limitations. Establishes the baseline material before introducing more demanding filaments.

Lesson 2 • ABS, ASA, and High-Temp Materials

Addresses warping, enclosure requirements, and fume management for ABS and ASA. Students configure enclosed printers for high-temperature materials.

Lesson 3 • Flexible Filaments: TPU and TPE

Explains shore hardness, retraction challenges, and direct-drive requirements for flexible filaments. Students produce functional flexible parts.

Lesson 4 • PETG: Strength and Flexibility

Details PETG's superior layer adhesion, moisture sensitivity, and stringing behavior. Students adjust settings to exploit PETG's functional advantages.

Lesson 1 • Diagnosing Adhesion Failures

Identifies causes of warping, lifting, and first-layer detachment. Students apply targeted fixes rather than random adjustments.

Lesson 2 • Extrusion and Flow Defects

Diagnoses under-extrusion, over-extrusion, and clogged nozzles through visual inspection. Connects defect appearance to specific hardware or slicer causes.

Lesson 3 • Layer Shifting and Ghosting

Traces layer shifts to mechanical causes and ghosting to resonance. Students tighten belts, adjust current, and apply input shaping.

Lesson 4 • Systematic Troubleshooting Workflow

Teaches a structured defect-diagnosis process using observation, isolation, and testing. Students build a personal troubleshooting reference log.

Lesson 5 • Stringing, Oozing, and Blobs

Addresses retraction, temperature, and travel speed settings that cause stringing and blobs. Students tune retraction profiles per material.

Lesson 1 • Mesh Repair and Optimization

Uses Meshmixer, PrusaSlicer, and Netfabb to fix non-manifold geometry and holes. Ensures models slice correctly without errors.

Lesson 2 • Scaling, Splitting, and Combining Models

Scales models for fit, splits large models for printing, and combines parts in slicer. Students handle real-world model preparation challenges.

Lesson 3 • Finding and Evaluating 3D Models

Navigates model repositories and evaluates files for printability and licensing. Students avoid wasted prints from poorly designed models.

Lesson 4 • Introduction to CAD for Printing

Introduces Fusion 360 and TinkerCAD for creating original printable geometry. Students design a simple functional part from scratch.

Lesson 1 • Chemical Smoothing Methods

Applies acetone vapor smoothing for ABS and XTC-3D epoxy coating for FDM parts. Students use chemical methods safely with proper PPE.

Lesson 2 • Support Removal and Cleanup

Removes supports cleanly using proper tools and techniques to minimize surface damage. Foundation step before any finishing process.

Lesson 3 • Assembly, Inserts, and Hardware

Installs heat-set inserts, magnets, and fasteners to create functional assemblies. Students produce multi-part functional objects.

Lesson 4 • Painting and Surface Finishing

Covers priming, airbrushing, and hand painting techniques for professional results. Students apply color and texture to completed prints.
