    Objectives

    By the end of the training, participants will be able to:

    • Adjust print settings based on material and application.
    • Diagnose and correct printing defects.
    • Perform essential 3D printer maintenance.
    • Produce high-quality, reliable prints.
    • Manage complex 3D printing projects independently.

    Program

    1️⃣ Review of Fundamentals

    • Quick recap of FDM printing principles: extrusion, adhesion, temperature, speed.
    • Understanding critical parameters: layer height, flow rate, cooling, infill density.
    • Identifying key factors that influence the final print quality.

    2️⃣ Materials and Print Profiles

    • Study of material properties: PLA, PETG, ABS, ASA, TPU.
    • Adjusting profiles based on the chosen material and use case (rigid, flexible, heat-resistant).
    • Best practices for filament storage and handling.
    • Practical exercise: comparative test using two different materials.

    3️⃣ Advanced Slicer Settings

    • Exploring advanced features in PrusaSlicer or Cura:
    • Custom support placement
    • Adaptive infill and internal structures
    • Progressive temperature settings (heat ramp, cooling optimization)
    • Speed and acceleration controls
    • Creating an optimized user profile tailored to specific project needs.

    4️⃣ Troubleshooting and Print Quality Improvement

    • Identifying and fixing the most frequent issues:
    • Layer shifting, surface artifacts, or poor bonding
    • Stringing, oozing, or nozzle clogs
    • Under/over-extrusion
    • Warping (bed adhesion problems)
    • Using diagnostic tools and methods for both software and hardware solutions.
    • Case study: analyzing a failed print and correcting it live.

    5️⃣ Maintenance and Calibration

    • Routine maintenance: checking belts, sensors, and extruders.
    • Cleaning and replacing nozzles (brass / steel / ruby types).
    • Calibrating bed level, flow rate, and Z-offset.
    • Best practices for long-term printer reliability and accuracy.

    6️⃣ Practical Project

    • Each participant completes a personal print project following a defined specification.
    • Validation of print settings and quality control (tolerances, strength, surface finish).
    • Presentation of the full workflow: design → slicing → printing → evaluation.
