Engineering Services
We provide end-to-end engineering support for physical product development. Our services span the complete design cycle – from initial concept validation through production-ready documentation. Each engagement is tailored to your project's specific requirements, technical constraints, and timeline.
What You Can Hire Us To Deliver
IAEngineering is strongest when a product needs more than a basic CAD operator. We combine mechanical engineering, manufacturing awareness, supplier-ready documentation, and prototype validation planning so teams can move with fewer avoidable loops.
Mechanical Design & 3D CAD
Comprehensive parametric modeling, finite element analysis (FEA), and technical documentation per ISO/ASME standards. We turn concepts into production-ready data.
Learn More
Manufacturing Engineering
Design for Manufacturing (DFM) optimization for injection molding, CNC, and sheet metal. We ensure your product is cost-effective to produce at scale.
Learn More
Prototyping & Validation
Rapid iteration support using 3D printing (SLA/SLS), CNC machining, and soft tooling. Verify fit, form, and function before committing to hard tooling.

Technical Consulting
Expert feasibility studies, design reviews, value engineering (VA/VE), and supplier liaison services for complex engineering challenges.

Manufacturability reviews for injection molding, CNC, sheet metal, 3D printing, and assembly.
Barcelona Engineering Consultancy
Local mechanical engineering and product development support for Barcelona and European clients.
Prototype Design and Validation
Prototype planning for looks-like, fits-like, works-like, and manufacturing-ready builds.
Technical Consulting
Feasibility studies, design audits, supplier liaison, value engineering, and project coordination.
Our Engineering Workflow
1. Discovery & Requirements
Every successful project starts with a clear understanding of the goals. We work with you to define the functional requirements, environmental conditions, and target manufacturing costs. This creates a "Product Design Specification" (PDS) that serves as the roadmap for the entire project.
2. Concept Design
We generate 3D concepts to explore different approaches. This phase focuses on feasibility and form. We use quick CAD models and basic renderings to visualize solutions, allowing you to choose the best path forward before committing to detailed engineering.
3. Detailed Engineering
This is where the heavy lifting happens. We refine the chosen concept into a fully detailed 3D assembly. We add fasteners, select off-the-shelf components, and detail every custom part. Finite Element Analysis (FEA) is often performed during this stage to verify structural integrity.
4. Prototyping & Validation
We produce prototypes to test form, fit, and function. Whether it's a 3D print to check ergonomics or a CNC-machined part for stress testing, this stage validates the design against the original requirements. We then iterate the digital model based on real-world findings.
5. Production Documentation
Once the design is finalized, we generate the 2D technical drawings and bills of materials needed for manufacturing. We ensure every drawing has the correct tolerancing (GD&T) to guarantee that the parts you order are the parts you get.
