Variables
Strengths & Limitations
Strengths
- +Comprehensive comparative analysis using established methodologies (LCA, LCC).
- +Inclusion of uncertainty analysis (Monte Carlo) to assess the robustness of findings.
Limitations
The specific findings are tied to the marine propeller example; results might differ for other product types or scales of production. The accuracy of the LCA/LCC depends heavily on the quality of the input data.
Reliability & validity
The study's reliability is supported by the use of established LCA and LCC methodologies and Monte Carlo simulation. Validity is strong within the specific context of marine propeller manufacturing, but generalizability to other products may be limited.
Think critically
How might the scale of production (e.g., mass production vs. bespoke manufacturing) influence the comparative advantages of WAAM, CNC milling, and SLM?
Design Principles
"Prioritize manufacturing processes that minimize material waste and energy consumption throughout the product lifecycle."
This research provides critical data for designers and manufacturers to select the most sustainable and cost-effective production methods.

The selection of manufacturing processes significantly impacts a product's environmental footprint and economic viability. Research by Kokare, Oliveira, and Godina (2023) demonstrated that for marine propellers, Wire Arc Additive Manufacturing (WAAM) offered a substantially lower environmental impact (2.5x less than CNC milling) and cost-effectiveness compared to traditional subtractive methods and Selective Laser Melting (SLM), primarily due to superior material and energy efficiencies. This highlights the importance of considering lifecycle assessments when choosing production methods.
