3D Modeling for Printing Course

Lesson 1 • Navigating 3D Modeling Software

Introduces the interface, viewport navigation, and tool panels of a parametric modeling application. Prepares students to work efficiently before creating geometry.

Lesson 2 • Core Geometric Concepts

Explains vertices, edges, faces, and mesh topology as the building blocks of all 3D models. Connects geometry theory to printability requirements.

Lesson 3 • File Formats and Export Standards

Covers STL, OBJ, 3MF, and STEP formats and their appropriate use cases. Students select the correct format for any downstream workflow.

Lesson 1 • Mirroring, Arrays, and Symmetry

Introduces mirroring and linear or radial array tools to replicate geometry efficiently. Reduces modeling time and ensures geometric consistency across repeated features.

Lesson 2 • Designing Your First Printable Object

Guides students through modeling a simple functional part using only primitives and booleans. Reinforces dimensional accuracy and export-ready geometry standards.

Lesson 3 • Boolean Operations for Solid Modeling

Applies union, difference, and intersection operations to combine or subtract geometry. Students create complex forms from simple primitives without manual mesh editing.

Lesson 1 • Parametric Assembly Basics

Introduces multi-body and assembly environments to position multiple parts relative to each other. Students verify fit and clearance before sending parts to the printer.

Lesson 2 • Parametric Dimensions and Constraints

Teaches dimensional parameters, named variables, and constraint-driven design intent. Models update predictably when a single parameter value is changed.

Lesson 3 • Fillets, Chamfers, and Detail Features

Applies edge treatments and secondary features to improve aesthetics and printability. Smooth transitions reduce stress concentrations and improve layer adhesion.

Lesson 4 • 2D Sketch Fundamentals

Covers drawing lines, arcs, circles, and polygons on a sketch plane with geometric constraints. Accurate sketches are the foundation of all parametric solid features.

Lesson 1 • Tolerances and Fit for Printed Parts

Covers dimensional shrinkage, thermal expansion, and clearance values for mating printed parts. Students apply tolerance offsets so assemblies fit without post-print modification.

Lesson 2 • Overhangs, Supports, and Bridging

Explains overhang angle limits, bridge span capabilities, and when support structures are necessary. Students redesign geometry to minimize support material and removal effort.

Lesson 3 • Orientation Strategy and Print Planning

Teaches how build orientation affects strength, surface finish, and support volume. Students choose optimal orientation for each part's functional requirements.

Lesson 1 • Layer, Infill, and Shell Settings

Explains layer height, infill density, infill pattern, and shell count and their effect on print quality and strength. Students select settings matched to each part's purpose.

Lesson 2 • Support Generation and Removal

Configures automatic and manual support structures, including interface layers and contact settings. Proper support setup reduces post-processing time and surface damage.

Lesson 3 • Importing and Orienting Models in a Slicer

Covers model import, placement, scaling, and rotation within slicing software. Correct orientation in the slicer is the first step toward a successful print.

Lesson 4 • G-Code Review and Print Simulation

Uses layer preview and G-code inspection to verify toolpaths before printing. Catching errors in simulation prevents wasted material and failed prints.

Lesson 1 • Joints, Hinges, and Linkages

Models pin joints, living hinges, and four-bar linkages for printed kinematic mechanisms. Students verify range of motion and clearance within the assembly environment.

Lesson 2 • Assembly Validation and Interference Checking

Uses software tools to detect collisions, interference, and clearance violations before printing. Catching fit errors digitally eliminates costly reprint cycles.

Lesson 3 • Designing for Disassembly and Serviceability

Applies design rules that allow printed assemblies to be disassembled, repaired, and reassembled. Reduces waste and extends the functional life of printed products.

Lesson 4 • Threaded Fasteners and Inserts

Teaches printed thread profiles, heat-set insert pockets, and captured nut traps for strong mechanical connections. Proper fastener design prevents stripping and part failure.

Lesson 1 • Retopology for Print-Ready Organic Models

Applies retopology techniques to convert high-poly sculpts into clean, printable meshes. Reduces file size and eliminates non-manifold errors common in sculpted geometry.

Lesson 2 • NURBS and Spline-Based Surfaces

Covers NURBS curves, loft surfaces, and patch modeling for mathematically smooth geometry. Ideal for product design surfaces requiring precise curvature continuity.

Lesson 3 • Introduction to Mesh Sculpting

Introduces sculpting brushes, dynamic topology, and symmetry sculpting for organic shape creation. Sculpting complements parametric modeling for ergonomic and artistic parts.

Lesson 1 • Topology Optimization for Printed Parts

Uses load-path analysis and topology optimization tools to remove unnecessary material while preserving structural performance. Results in lighter parts with optimized internal geometry.

Lesson 2 • Iterative Design and Version Control

Establishes a structured iteration workflow using version naming, change logs, and test print documentation. Students manage design evolution professionally across multiple print revisions.

Lesson 3 • Generative and Lattice Structures

Creates internal lattice infill and generative surface structures to reduce weight without sacrificing stiffness. Students select lattice cell types matched to load requirements.

Lesson 4 • Texture Mapping and Surface Detail

Applies displacement maps and procedural textures to add surface detail without increasing base mesh complexity. Enhances visual quality of printed models with minimal file size impact.
