This technical report describes a detailed blade cost model for wind turbine blades in the range of 30 to 100 meters in length. The model estimates the bill of materials, the number of labor hours and the cycle time, and the costs related to direct labor, overhead, buildings, tooling, equipment, maintenance, and capital.
Assuming labor rates of $50/hr and machining rates of $150/hr, the total tool cost was approximately $1870 (Table 1). In terms of manufacturing time, from beginning to end, it took approximately two days to fully manufacture the mold. In comparison to SLS in the BAAM provides a more balanced distribution of costs.
From estimated cost data, a cost curve was plotted for spar cap cost against blade length. For validation, the curve was compared with one independently derived by a 35 m wind turbine.
A blade is one of the most expensive and time-consuming wind turbine components to manufacture, and that cost is rising as demand for larger blade sizes grows. Additive manufacturing eliminates the need for the plug, and building ducts into the mold’s design allows manufacturers to cure the mold’s fiberglass finish with hot air, eliminating .

6 FAQs about [Wind turbine blade mould cost]
Why are wind turbine blades so expensive?
Blades are one of the most expensive components of wind turbines, and that cost is rising with the demand for larger blade sizes. By pursuing direct printing of the molds, researchers targeted greater efficiency and cost savings as part of DOE’s commitment to improve the competitiveness of US manufacturers.
How are material costs related to wind blade manufacture?
Material costs were similarly generated from the detailed BOM, and allocated into direct, scrap, consumable, and indirect material costs. In addition, the overhead and business costs associated with wind blade manufacture have been more fully explored and detailed from what has been done in previous studies.
Does thermoplastic resin reduce wind turbine blade cost?
Conclusions Results of the techno-economic model show that a thermoplastic resin wind turbine blade has the potential to reduce the overall blade cost by 4.7% compared to a thermoset epoxy baseline blade.
Can 3D printing be used to make wind turbine blade molds?
DOE’s Wind Energy Technologies Office (WETO) and Advanced Manufacturing Office (AMO) are partnering with public and private organizations to apply 3D printing, or additive manufacturing, to the manufacturing of wind turbine blade molds.
What is a techno-economic model for Wind Blade?
A comprehensive techno-economic model for wind blade should consider four cost categories: labor, material, overhead, and business. Labor hours were examined and modeled by the authors in Ref. [ 21 ], and that model can serve as the basis for labor costing.
Can additive manufacturing be used in Wind Blade mold fabrication?
Researchers examined how additive manufacturing could be used in wind blade mold fabrication to decrease lead time and costs, leveraging technology at the DOE Manufacturing Demonstration Facility (MDF) at ORNL.
