Material Detail

This peer-aligned, Washington Accord-compliant educational module presents an engineering economics and techno-economic evaluation framework comparing Additive Manufacturing (AM) against conventional subtractive (CNC milling) and formative (injection molding) production methods.

Key topics covered include:- Total and unit production cost models: C_total(N) = C_fixed + N * C_marginal.- Exact algebraic derivation and graphical interpretation of the breakeven lot size crossover threshold (N*).- Four-pillar industrial cost decomposition for Laser Powder Bed Fusion (LPBF): capital machine amortization, gas-atomized powder and inert shielding consumables, secondary post-processing (Wire EDM, HIP, precision finishing), and technical metrology/labor.- Straight-line capital depreciation models incorporating Overall Equipment Effectiveness (OEE) and operational utilization.- Supply chain logistics: digital inventory repositories, lead-time reduction, elimination of safety-stock holding overheads, and the economic justification of on-demand additive production in mission-critical applications.- Fully worked numerical engineering case studies and self-assessment quantitative review problems.

Curriculum Context: Module 10 of the Additive Manufacturing & 3D Printing Engineering Series.Canonical Web Location: https://prep4uni.online/stem/physical-technologies/industrial-and-manufacturing-technologies/additive-manufacturing-3d-printing/economics-breakeven-future/
