We just published a course on the freeCodeCamp.org YouTube channel that will teach you about basic desktop printing and industrial-grade additive manufacturing.

This course covers the entire lifecycle of additive manufacturing, taking you from fundamental concepts to enterprise-level workflows:

• Industry 4.0 & Smart Manufacturing: How cyber-physical systems, IoT, and cloud computing integrate with 3D printing to create smart factories.

• Core Printing Technologies: Deep dives into ASTM-classified methods including Material Extrusion (FDM), Vat Photopolymerization (SLA/DLP), Powder Bed Fusion (SLS/SLM), Binder Jetting, Directed Energy Deposition (DED), and Hybrid manufacturing.

• Real-World Sector Applications: Case studies exploring aerospace fuel nozzles, custom craniomaxillofacial medical implants, automotive topology-optimized brackets, and energy sector gas turbines.

• CAD Pre-Processing & Slicing: Managing 3D data formats (STL, OBJ, 3MF), optimizing print orientation, generating support structures, and mastering slicing parameters.

• Materials Science: Material selection across thermoplastics (PLA, ABS, Nylon), photopolymer resins (Standard, Tough, Dental), and industrial metal alloys (Titanium Ti-6Al-4V, Inconel, Copper, Stainless Steel).

• Design for Additive Manufacturing (DFAM): Leveraging simulation-driven design, topology optimization, generative design, and part consolidation to produce lighter, stronger components.

• Digital Inventory & Warehousing: Transitioning from physical warehouses to on-demand, decentralized digital supply networks.

• Quality Control & Post-Processing: Addressing printing defects (warping, delamination, porosity), in-situ process monitoring, destructive/non-destructive testing (CT scanning, CMM), and post-processing finishing steps.

You can watch the full course directly on the freeCodeCamp.org YouTube Channel for free (7-hour watch).
