Product Development Engineering: From Concept to Production-Ready CAD
Founder-led mechanical design, DFM review and prototyping for startups and manufacturers. Fusion 360 CAD, ANSYS FEA and Moldflow checks, delivered as supplier-ready STEP files and drawings.
Integrated Engineering Services
Product development needs design intent, manufacturing constraints and cost targets to stay in step. IAEngineering is founder-led: you work directly with the engineer doing the design, from first feasibility checks to production documentation. Models are built in Fusion 360 and validated with ANSYS and Moldflow where it changes the decision. You receive STEP and IGES files, drawings and BOMs that open in SolidWorks and any other CAD system.

How an Engagement Works
- BriefSend sketches, CAD, drawings or just the problem. Need an NDA first? We agree it before you share anything sensitive.
- ScopeYou get a written scope, deliverables, schedule and price before work starts. The first DFM review of one part is free.
- DesignParametric CAD in Fusion 360 with DFM, tolerance and FEA or Moldflow checks where they change the decision, plus review calls.
- HandoverSTEP/IGES models, 2D drawings with GD&T, BOM and supplier notes, so your manufacturer can quote and build.
IAEngineering is led by Ignas Anskaitis, a mechanical engineer (B.Sc., University of Twente) and former process development engineer in microfluidics manufacturing. Based in Barcelona, working in English, Spanish and Lithuanian with clients across Europe and beyond.
Engineering Support Built for Real Product Decisions
Most product delays come from unclear requirements, incomplete CAD handovers, weak tolerance decisions, or design choices that do not match the intended manufacturing process. IAEngineering focuses on the technical work that moves a physical product from an idea toward a buildable, quoted, tested, and documented design package.
Production-ready CAD handoff
Fusion 360 models, STEP/IGES exports, manufacturing drawings, GD&T notes, and BOM data can be prepared so suppliers have a clear package to quote and build from.
DFM before expensive tooling
Parts are reviewed for wall thickness, draft, undercuts, CNC access, bend allowances, tolerance stack-up, assembly sequence, material selection, and supplier feedback.
Prototype learning loops
Prototype builds are planned around the question that needs answering: fit, function, strength, ergonomics, thermal behavior, assembly access, or production readiness.
See the engineering communication, not just the service list
These visuals come from the founder's public portfolio. They are portfolio visualizations, not claims of a completed IAEngineering client project, tested performance or production approval.
Internal layout: mechanism and enclosure
Useful for discussing component fit, assembly access and the interfaces a CAD brief must define.
Exploded assembly communication
Useful for discussing assembly order and the information a supplier-facing documentation package needs.
Sealed enclosure stack-up
Useful for agreeing how the housing, gasket, fasteners, connectors and PCB fit together before parts are quoted.
Tooling context
Useful for discussing mould constraints early: parting lines, ejection, cooling and slide actions.

Frequently Asked Questions
What industries do you serve?
We work across multiple sectors including consumer electronics, industrial equipment, medical devices, and custom machinery. Our methodology adapts to the specific requirements and regulatory standards of each industry. We work with the documentation practices of medical-device and consumer-product development, but certification stays with you and your notified body.
What documentation do you need to begin?
Projects can begin from various starting points: conceptual sketches, existing 2D drawings (DWG, PDF), 3D models (STEP, IGES, SolidWorks parts and assemblies), or detailed functional specifications. We adapt our workflow to your available documentation and fill in gaps as needed during the design process.
Do you provide prototyping support?
Yes. We prepare manufacturing-ready files and provide guidance on selecting appropriate prototyping methods based on your requirements: additive manufacturing (FDM/SLA/SLS) for rapid iterations, CNC machining for functional metal parts, or sheet metal fabrication for enclosures and brackets.
How much does it cost and how long does it take?
Every engagement starts with a written scope, price and schedule. The first DFM review of one part or assembly is free; paid work is quoted per deliverable or by the hour once we have seen your files. A simple part optimization can take a few days, a full product development cycle weeks.
Which CAD software and file formats do you use?
Fusion 360 for parametric CAD, ANSYS for FEA and Moldflow for injection-molding checks. We exchange STEP, IGES, STL, DXF/DWG and PDF. SolidWorks users can open our STEP and IGES exports, and we can open SolidWorks parts and assemblies (SLDPRT/SLDASM) you send us. Native SolidWorks files are not part of our deliverables.
Who will work on my project?
IAEngineering is founder-led: Ignas Anskaitis, a mechanical engineer with a B.Sc. from the University of Twente, does the design work himself and brings in manufacturing partners for CNC, molding or sheet metal when a project needs production.
