Prototype Development and Manufacturing Support Service

Where Thinking Meets Testing and Becomes Real

At MILIVOJA, we don’t just design. We build. Because ideas don’t become products until they’re tested, broken, refined, and built again. Prototype development is where assumptions end and learning begins. It’s the part of the process where you stop guessing and start knowing.

From early look-alike models to high-fidelity, production-intent prototypes, we build what it takes to validate your product before investing in full-scale manufacturing. And when it’s time to move forward, we stand beside you in the handoff to production, helping you maintain quality, cost control, and design intent at every stage.


We work with startups launching their first pilot and global teams prepping for tooling. Wherever you are on the path from concept to product, we help you move forward with certainty and speed.

Why Prototyping Matters

Because the First Version Is Never the Final One

Sketches lie. Renderings flatter. But prototypes? They tell the truth. They reveal what breaks, what fits, what surprises people, and what just doesn’t work. Prototyping gives us feedback that the market eventually will. We just get it early, when it’s still cheap to change.

Whether you’re testing ergonomics, user interaction, thermal management, or manufacturability nothing replaces physical validation. And in regulated or mission-critical industries, that early insight can mean the difference between a smooth launch and a costly rework.

At MILIVOJA, we build to test, test to learn, and learn to improve because it’s easier to fix problems on the bench than in the field.

Our Prototyping Approach

Fast, Functional, Feedback-Driven

Every prototype we build has a purpose. Sometimes that means speed. Sometimes it means Polish. But always it means learning. We tailor our prototyping approach to match what your team needs to validate next.

Define Prototype Objectives

Before we start building, we align on what the prototype is meant to prove. Is it for ergonomic testing? Engineering validation? A pitch demo? Pilot production?

We clarify
  1. What needs to be tested or demonstrated
  2. What level of fidelity is required
  3. Which materials, tolerances, or interactions matter most
  4. Who the prototype is for (internal, investor, user, regulator)


Clarity here keeps us fast, focused, and effective.

Select the Right
Build Path

We’re technology-agnostic. We don’t push one method we use the one that fits. Whether it’s additive manufacturing, CNC, sheet metal, soft tooling, or hybrid builds, we choose based on speed, cost, and relevance to production.

We regularly use
  1. SLA, SLS, MJF, and FDM 3D printing
  2. Urethane casting for production-like textures and finishes
  3. CNC machining for metal, plastics, and composites
  4. Rapid injection molding or vacuum forming
  5. Assembly mockups with off-the-shelf + custom parts

We often combine methods printing a housing, machining brackets, laser-cutting internals to get exactly what the prototype needs without wasting time.

Build, Test, Refine

We move quickly, but precisely. We assemble prototypes in-house or with trusted partners. And we test them not in a white room, but in conditions that simulate real use.

We evaluate
  1. Fit, finish, and mechanical behavior
  2. Stress points and wear zones
  3. Assembly ease and fastening logic
  4. Ergonomic feel and user response
  5. Performance under thermal, vibration, or drop loads

Then we iterate. Because the first prototype isn’t about perfection it’s about information. We document learnings, adjust designs, and prepare for the next cycle. Fast loops mean fast progress.

Functional Integration

For products involving electronics, sensors, displays, or moving parts, we integrate functional hardware into prototypes. This enables real-world testing and user trials.

We can support
  1. Embedded system setup and wiring
  2. Sensor and actuator integration
  3. Light guides and display fitting
  4. Basic firmware loading for interaction demos

The goal isn’t to fake functionality, it’s to simulate it well enough to gather real feedback.

Pilot Builds & Bridge Manufacturing

What Comes After the First Working Unit

Once your design is proven and ready to scale, we support the next step: building a small run for deeper testing, regulatory trials, or early user deployment. This is where DFM (Design for Manufacturing) becomes more than a theory it becomes a necessity.


We support:

  1. Pilot builds of 5–500 units
  2. Short-run tooling for injection molding or metal forming
  3. Assembly line setup and work instructions
  4. Manufacturing BOM generation and cost tracking
  5. Supply chain sourcing for mechanical components


We also coordinate with your production partners, validate samples, and ensure your design survives the transition to the factory floor because good design doesn’t mean much if it doesn’t survive tooling.

Manufacturing Support

Ready for Production—Without the Guesswork

We don’t just hand off files and walk away. We guide you through production setup, factory selection, and tooling readiness. We stay involved so that your product gets built the way it was designed no shortcuts, no surprises.

Our manufacturing support includes

  1. DFM reviews with vendors
  2. Tolerance analysis and assembly testing
  3. Feedback loop for tooling modifications
  4. Sample inspection and root cause analysis
  5. Final spec documentation for all components

If you don’t have suppliers, we help source them. If you do, we act as an extension of your team, translating design into manufacturing language and helping troubleshoot every step of the way.

For regulated products, we assist with

  1. Technical documentation and build traceability
  2. Regulatory submission samples
  3. Pre-compliance verification and risk analysis


Our role is to reduce friction, de-risk decisions, and accelerate your path to production.

Why MILIVOJA for Industrial Design?
Because Real Products Need Real Engineering.

We’re not theoretical. We’re tested. Our engineers have delivered mechanical systems for:

  1. Electric drivetrains
  2. Robotics linkages
  3. Consumer electronics housings
  4. Medical device frames and mechanisms
  5. Thermal and structural components in EVs and mobility systems


We know what works and what breaks. That saves you time, cost, and reputation risk.

Built-In Engineering Rigor

Our prototyping process is backed by real engineering. That means assemblies that fit, tolerances that hold, and geometry that translates. We don’t build “pretty” prototypes, we build prototypes that work.

Trusted Vendor Network

We’ve spent years building relationships with prototype houses, rapid tooling shops, and manufacturing partners who deliver on time, on spec, and without drama.

Prototype to Production, Without Gaps

We know how to scale. And we help clients avoid the most common pitfall: building a prototype that can’t actually be manufactured. Our designs are built to bridge.

Clear, Collaborative Process

Weekly check-ins. Shared documentation. Aligned decisions. Whether you’re running lean or scaling fast, we meet your cadence and keep communication open - no black boxes.

Let’s Build the Version That Gets You to the Next Stage

If you’re stuck in the idea stage, let’s build the first thing that proves it works. If you’ve validated the design, let’s build the version that’s ready for 500 units. Whatever your next milestone is, we’ll help you build the version that gets you there.
