3D Animation for Industry, Defense and Serial Production

Modii3D’s 3D animation is a precise, moving visualization of a mechanism, process, or product, built directly from the client’s technical documentation — CAD, STEP, and IGES files — and covered by an NDA from the very first stage of the project. We work with industrial plants, the defense sector, medical and pharmaceutical companies, machinery manufacturers, and businesses selling high-volume products, from a single concept animation to variant libraries running into the hundreds of files.

This service covers 3D animation only — objects, mechanisms and processes in motion. For static 3D renders, see our 3D Visualization service.

Why Modii3D?

Modii3D builds every 3D animation from real technical documentation, so each frame matches the production geometry of the actual product rather than a simplified marketing version. We work directly from CAD and STEP files supplied by the client’s engineering or design department — we cover the import, repair, and optimization process step by step in our guide, STEP files in 3D animation — a guide for companies.

• Documentation as the source of truth — the 3D model is built from CAD/STEP files rather than reference photos, eliminating dimensional discrepancies from the real product.
• Data confidentiality (NDA) — we sign a non-disclosure agreement as standard practice before any project documentation is shared, regardless of project size.
• Production scalability — a single base model can generate dozens of color, configuration, or size variants without remodeling from scratch.
• An engineering-first approach — we review geometry and tolerances directly with the client’s R&D or design engineering team, not only with marketing.

Pricing: tell us what the animation should show and attach CAD files (preferably .STEP) if you have them. We reply within 24 hours. Projects start from EUR 1,500 net.

Industries and Specializations

Modii3D delivers 3D animation across three industry areas: heavy industry and critical infrastructure, machinery and technical products, and serial production sold through B2B and e-commerce channels. The full portfolio of completed projects is available in the Modii3D project catalog.

Heavy Industry, Energy, Rail and Defense

In this area, 3D animation captures large-scale technological processes, installations, and infrastructure — from power plants to rail networks — based on design documentation, 3D scans, or on-site surveys. Our work includes an animation of an electric steel plant complex, technical materials for PGE, and an animation showing the reconstruction of railway infrastructure. For PEC Gliwice, we produced animations of a district heating installation, and for the mining sector, a 3D animation project for Nepean. The portfolio also includes work for Carbospec and Exme Berger Group.

In the defense sector, we produce 3D animations of military equipment and systems under the confidentiality standards specific to this industry, including work on segregated infrastructure and restricted access to source files. Example project: 3D animation for the defense sector.

Machinery, Equipment, Automotive and Medicine

For machinery and component manufacturers, 3D animation demonstrates how a mechanism works, an assembly sequence, or an equipment’s operating cycle in ways a photograph simply cannot capture. Examples include a technical animation produced for AS Technik and a project showcasing components for the automotive industry. We have also delivered product animations for Boccard Kates and Niczuk Thale — roofing construction systems, along with a 3D industrial product animation campaign for the CVA brand.

In the medical and pharmaceutical sector, 3D animation supports the presentation of equipment and procedures in 360°/VR format, letting viewers explore the model independently from any angle. Example project: 360°/VR medical animation.

B2B E-commerce, Joinery and Serial Production

For products sold in high volumes — lighting, pergolas, fencing, window joinery, roller shutters, and balustrades — 3D animation shows assembly and product variants without the need to physically prototype every version. Our work includes window joinery animations for the Salamander brand, a roller shutter assembly animation, and the Balustrady Smart project.

The 3D Animation Production Process

The 3D animation production process at Modii3D covers six stages — from analyzing engineering documentation to delivering the final render — described in detail in our 3D animation guide for businesses.

1. Documentation review and NDA — we review the CAD/STEP files and project scope after signing an NDA, before preparing a detailed quote.
2. Script and technical storyboard — we define the shot sequence, camera angles, and key highlights (e.g. cross-sections, exploded assembly views), approved by the client before animation begins.
3. Geometry optimization — the CAD/STEP model is cleaned up, retopologized, and prepared for animation; this stage determines the final render’s quality and turnaround time.
4. Animation and motion simulation — we bring the model to life with movement that matches the real kinematics of the mechanism or process (rigging, keyframe animation, physics simulations).
5. Rendering and post-production — the final render is produced in the resolution and format agreed at the start of the project, including color grading, compositing, and sound design.
6. Delivery and variants — the finished material is delivered in the agreed formats (including MP4, MOV, WebM, and 360°/VR), along with any language or color variants included in the order.

Technical terms used in this process — such as topology, rigging, or poly count — are explained in our 3D graphics glossary.

How Much Does 3D Animation Cost?

The cost of 3D animation depends on five main factors: the complexity of the model’s geometry, the length and number of shots, the level of render realism, the number of product variants, and the number of revision rounds included in the agreement. We publish a detailed price list, budget ranges, and calculation examples in the article How Much Does 3D Visualization and Animation Cost?

• Geometry complexity — the number of moving parts, level of detail, and the starting condition of the CAD/STEP model.
• Length of the material — the number of seconds and shots in the final animation and the number of independent scenes.
• Level of realism — from a simplified concept animation to a fully photorealistic render.
• Number of variants — color options, configurations, language versions.
• Revision rounds — the number of iterations and approval stages defined in the project agreement.

Frequently asked questions

How much does a 3D animation cost?

Projects start from EUR 1,500 net, and a typical technical animation falls between EUR 1,500 and 4,500 net. The final figure depends on the length of the material, the number of models and variants, the level of photorealism, and whether you can supply CAD documentation. We walk through detailed calculation examples in How much does a 3D visualization and animation cost?

Can I send my own CAD or STEP files for a quote?

Yes — CAD/STEP files are our preferred input format and allow the most accurate quote without a modelling-from-scratch stage. We accept STEP, IGES and Parasolid, as well as native files from common CAD systems. How to prepare the export is covered in our guide to STEP files.

Do you sign an NDA before receiving technical documentation?

Yes. We sign an NDA as standard before any project files are shared, regardless of the size of the commission. This applies in particular to defence and medical projects.

How long does a 3D animation take to produce?

Standard lead time is 3 to 8 weeks, counted from storyboard approval to delivery of the final render. Shorter product animations close nearer the lower end, while projects with many variants or photorealistic rendering require a longer schedule, which we agree before we start. The production stages are described in our 3D animation guide for businesses.

Can you produce an animation without a CAD model, from 2D drawings or photographs?

Yes. A 3D model can be rebuilt from 2D technical drawings or photographic material through reverse modelling, although this extends the timeline and increases the risk of dimensional discrepancies. Where possible we recommend CAD/STEP documentation as the most accurate source.

In what formats and resolutions do you deliver finished animations?

We deliver in MP4, MOV or WebM at up to 4K as standard, and additionally in 360°/VR for medical and product presentations. On request we also prepare a version with an alpha channel for compositing on a website. Technical terms are explained in our 3D graphics glossary.
