The Laminated Object Manufacturing (LOM) Masterclass is a comprehensive professional training program designed to take learners through the engineering, operational, and material foundations of sheet lamination additive manufacturing. The course establishes a deep theoretical and practical understanding of how 3D objects are created by sequentially layering, adhesive-bonding, and laser-cutting sheet materials, tracing the technology's development from early Helisys platforms to modern industrial systems. Learners explore the underlying physics of layer construction, material feed systems, heated roller lamination, and automated platform indexing.
Participants will develop technical proficiency in CO2 laser cutting optics, kerf compensation calculations, cross-hatching strategies for waste removal, and thermal adhesive bonding mechanisms including hot-melt thermoplastics and pressure-sensitive systems. The curriculum provides an exhaustive exploration of material systems, covering standard adhesive-coated kraft paper, thermoplastic films (PP, PE, PET, PVC), fiber-reinforced composite sheets, and solid-state Ultrasonic Additive Manufacturing (UAM) for metal foils. The course also guides students through the complete production workflow, including CAD mesh repair, watertight STL validation, slicing parameter selection, machine bed calibration, and manual or chemical post-processing techniques like decubing, sanding, and sealing.
Through detailed international case studies and industrial examples from the United States, the United Kingdom, Germany, and Australia, learners examine real-world implementations across aerospace tooling at Boeing, large-scale architectural master planning at Pipers Model Makers, automotive exterior prototyping at BMW Designworks, and heavy mining vehicle development.
About the Course Program
This course is structured to provide an authoritative, industry-aligned education in sheet lamination technologies defined under ISO/ASTM 52900 standards. The curriculum balances mechanical engineering principles with hands-on shop-floor procedures, focusing on how sheet-based additive manufacturing achieves rapid build speeds, high dimensional stability, and low material costs for large components.
The program bridges the gap between digital CAD modeling and physical manufacturing, emphasizing practical design-for-additive-manufacturing (DfAM) constraints, post-processing durability, and multi-material integration. By combining clear technical explanations with proven industrial methodologies, the course equips professionals to evaluate, implement, and optimize LOM technology within modern manufacturing, design, and prototyping workflows.
