Product Visualization & Mechanical Design - Barcelona

Product Visualization & Mechanical Design

A mechanical engineer who renders. I help product teams, manufacturers, and brands turn concepts into photorealistic product, packaging, and exhibition visuals — backed by real CAD, DFM, and manufacturing knowledge.

01

Product & packaging visuals

Clean product views, campaign scenes, label variants and technical cutaways for a launch or catalogue.

Plan your product renders →
02

Named engineering support

Work directly with me on CAD, assemblies and drawings. Manufacturing-focused product development and DFM enquiries can go through my engineering business, IAEngineering.

03

A clear scope before work

Visualization quotes include two consolidated revision rounds within the agreed brief. Extra rounds, new views or design/scope changes are quoted separately before work. Deliverables, usage rights, source files, price and schedule are agreed in writing after reviewing the inputs; no universal rush-delivery promise.

About

Mechanical Engineering Meets
Creative Vision

I'm a freelance Mechanical Engineer (B.Sc. University of Twente) focused on product development, 3D CAD, DFM, and precision manufacturing.

Before establishing IAEngineering, I spent years at Micronit as a Process Development Engineer and Researcher in the microfluidics sector. There, I developed custom C# intranet systems, optimized CNC machining accuracy to 5-micron assembly tolerances, and slashed an additive manufacturing development timeline from 5 months to just 2 weeks.

Today, I leverage that rigorous engineering background to deliver end-to-end CAD design and 3D visualization — ensuring every product is not only visually striking but technically sound, documented, and production-ready.

Before We Start

Questions Before We Start

A short project brief is enough to work out the right next step.

Can I start with a sketch, photo, or existing CAD?

Yes. A sketch, photo, reference product, or existing CAD file is enough to define the next engineering step.

Do you prepare files for manufacturing?

Yes. Support can include production-ready CAD, assemblies, technical drawings, exports, and DFM review for CNC, 3D printing, and injection molding.

Do you work with international product teams?

Yes. I am based in Barcelona and work remotely with international teams in English, Spanish, and Lithuanian.

How are price and scope handled?

Visualization is quoted as a fixed price for a defined set of views after I review your inputs, with two consolidated revision rounds included. Engineering is scoped per deliverable or by the hour. You get the estimate in writing before any work starts.

Do you sign NDAs?

Yes. Ask for an NDA before sending confidential CAD, drawings or unreleased products. Files travel through a secure sharing link, never through the form.

Which file formats can I send and receive?

Send STEP, IGES, STL, DXF/DWG, Fusion 360, Blender or FBX/OBJ files, or only sketches and reference photos. I deliver renders as PNG/JPG/TIFF (MP4 for animations), CAD as STEP/IGES/Fusion 360 files and drawings as PDF/DXF. SolidWorks users can open the STEP and IGES exports.

Who will I work with?

Directly with me, Ignas: the engineer who also builds the visuals. Questions and revisions go straight to the person doing the work.

How do we get started?

Send the brief below: what you are making, what you already have and your deadline. I reply by email with questions or a scoped next step, then confirm price, schedule and deliverables in writing before work begins.

Contact

Send the brief.
Get a clear
next step.

You do not need a finished specification. Send a sketch, photo, existing CAD file, target process, or short description of the problem. I will reply with the right next step.

  • What are you making or visualizing?
  • What do you already have?
  • What needs to be decided?
  • What is the target deadline?

By sending, you share your details with Ignas Anskaitis to respond to your enquiry. Formspree processes this form. Do not send confidential files here: ask for an NDA and secure sharing link first. Formspree privacy.
