Resin 3D Printing Course

Lesson 1 • Printer Hardware Components

Identifies every major hardware component and its function within the print system. Provides the vocabulary needed to troubleshoot and maintain equipment throughout the course.

Lesson 2 • Workspace Setup and Organisation

Covers ventilation, lighting, surface protection, and tool placement for an efficient resin workspace. A properly organised workspace reduces errors and exposure risks.

Lesson 3 • Essential Tools and Consumables

Lists and explains every tool and consumable required before printing begins. Students leave this section ready to stock and equip a functional resin printing station.

Lesson 4 • Resin Printer Types and Technologies

Compares SLA, DLP, and MSLA/LCD printer architectures and their trade-offs. Helps students select the right technology for specific print requirements.

Lesson 1 • Reading and Interpreting Resin Data Sheets

Teaches students to extract exposure settings, mechanical properties, and safety data from manufacturer documentation. Accurate data-sheet reading prevents print failures and safety incidents.

Lesson 2 • Health and Safety with Resin Materials

Addresses skin sensitisation, inhalation risks, and safe disposal of uncured resin. Compliance with safety practices protects health and meets workplace chemical-handling standards.

Lesson 3 • Resin Storage and Handling

Covers proper storage conditions, shelf life, and contamination prevention for liquid resins. Correct handling preserves resin quality and reduces material waste.

Lesson 4 • Standard and Specialty Resin Types

Surveys standard, ABS-like, flexible, castable, water-washable, and engineering resins. Knowing each type's strengths guides appropriate material choice for each application.

Lesson 1 • Slicer Interface and Navigation

Introduces the slicer workspace, menus, and viewport controls used throughout the course. Fluency with the interface accelerates all subsequent slicing tasks.

Lesson 2 • Exposure and Layer Settings

Covers layer height, normal exposure time, bottom exposure time, and lift speed parameters. Dialling in these settings determines print success, accuracy, and resin consumption.

Lesson 3 • Orienting Models for Optimal Printing

Explains how print orientation affects surface quality, support load, and suction forces. Correct orientation is the single most impactful decision in the slicing workflow.

Lesson 4 • Hollow and Infill Strategies

Teaches hollowing models and adding drain holes to reduce resin use and internal pressure. These strategies lower cost and prevent print failures on large solid models.

Lesson 1 • Auto-Support Generation and Editing

Covers automatic support generation tools and manual editing workflows in the slicer. Auto-supports provide a starting point that manual refinement optimises for each model.

Lesson 2 • Why Supports Are Necessary

Explains overhangs, islands, and suction forces that require support structures in resin printing. Understanding the physics of failure motivates precise support placement decisions.

Lesson 3 • Support Types and Anatomy

Describes light, medium, and heavy support types along with their tip, pillar, and base geometry. Matching support type to geometry prevents surface damage and print failure.

Lesson 4 • Strategic Support Placement Techniques

Teaches placement strategies that minimise visible marks on cosmetic surfaces. Strategic placement balances structural adequacy with post-processing ease.

Lesson 1 • Post-Print Printer Maintenance

Details vat cleaning, FEP inspection after printing, and resin storage after a session. Routine maintenance extends printer life and prevents contamination of future prints.

Lesson 2 • Build Plate Leveling Methods

Compares paper-method, digital, and tilt-and-lock leveling approaches for different printer types. Accurate leveling is the most critical factor in first-layer adhesion.

Lesson 3 • Pre-Print Preparation Checklist

Establishes a systematic pre-print routine covering leveling, resin filling, and FEP inspection. A consistent checklist eliminates the most common causes of print failure.

Lesson 4 • Starting and Monitoring a Print

Guides students through initiating a print job and monitoring early layers for adhesion. Early detection of failure saves resin and prevents vat contamination.

Lesson 1 • UV Curing Science and Parameters

Explains how post-cure UV exposure completes polymerisation and improves mechanical properties. Correct cure parameters prevent brittleness, tackiness, and dimensional distortion.

Lesson 2 • Support Removal Timing and Workflow

Explains when to remove supports—before or after curing—and the trade-offs of each approach. Timing support removal correctly minimises surface damage and part distortion.

Lesson 3 • Washing Fundamentals and Solvents

Explains how washing removes uncured resin from part surfaces and which solvents are appropriate. Choosing the correct solvent prevents part degradation and ensures safe handling.

Lesson 4 • Cure Validation Methods

Teaches tactile, visual, and hardness-testing methods to confirm complete cure. Validated cure ensures parts meet mechanical and safety requirements before use.

Lesson 1 • Sanding and Surface Preparation

Covers wet and dry sanding progressions from coarse to fine grits for resin surfaces. Systematic sanding is the foundation of all subsequent finishing steps.

Lesson 2 • Priming for Paint Adhesion

Explains primer selection, application technique, and curing for resin substrates. Primer reveals surface defects and ensures durable paint adhesion on photopolymer surfaces.

Lesson 3 • Clear Coating and Sealing

Teaches matte, satin, and gloss clear coat application to protect and unify painted surfaces. Sealing locks in paint layers and provides UV and abrasion resistance.

Lesson 4 • Specialty Finishing Effects

Introduces metallic powders, washes, dry-brushing, and resin tinting for decorative effects. These techniques expand the creative range of finished resin parts.

Lesson 1 • Dimensional Accuracy and Tolerances

Explains how to measure printed parts and adjust scaling and anti-aliasing for accuracy. Dimensional control is critical for functional, mechanical, and dental applications.

Lesson 2 • Optimising Print Speed and Efficiency

Covers lift speed, TSMC/LGS motion profiles, and batch printing strategies to maximise throughput. Speed optimisation reduces print time without sacrificing part quality.

Lesson 3 • Diagnosing Print Failures

Provides a structured diagnostic framework for identifying failure types from visual evidence. Systematic diagnosis prevents guesswork and reduces wasted resin and time.

Lesson 4 • FEP and Vat Maintenance Issues

Addresses FEP clouding, micro-tears, and cured resin contamination in the vat. Maintaining a clean, clear FEP is essential for consistent light transmission and print quality.
