What do you need from me to get started?

We require a clear project brief including sketches, reference images, dimensions, and functional requirements. Please also specify your intended manufacturing method and target budget to ensure we engineer the product correctly from day one.

Is the cost of the physical prototype included in your packages?

No. Our fees cover the engineering design, 3D modeling, simulation, and technical documentation. We provide the manufacturing-ready files (DFM) you need to send to a prototyping facility or manufacturer.

What if I don't like the initial design?

This is why our workflow includes a dedicated "Concept & Ideation" phase. We present initial directions for your approval before beginning detailed engineering. This ensures the final output aligns perfectly with your vision.

Why should I choose you over a cheaper designer?

We are degreed engineers, not just 3D modelers. We ensure your product is physically viable, manufacturable, and mechanically sound. Investing in professional engineering now prevents expensive re-tooling errors during manufacturing.

Do you provide Non-Disclosure Agreements (NDAs)?

Yes. We respect client confidentiality and are fully willing to sign an NDA before discussing your intellectual property or project details.

What file formats will I receive?

You will receive industry-standard 3D source files and 2D technical drawings ready for manufacturers.

Can you help me find a manufacturer?

While we do not handle manufacturing in-house, we provide comprehensive manufacturing support. We can recommend vetted partners and communicate with vendors to ensure your technical drawings are understood.

Do you only work with clients in Miami?

No. Sebar Design works remotely with startups and businesses across the United States. Our team is based in Miami, FL and Boston, MA, and all engineering deliverables (CAD files, technical drawings, and simulation reports) are delivered digitally, so location is never a barrier to working together.

What is a fractional product designer or engineer?

A fractional product designer or engineer provides senior-level mechanical engineering and industrial design expertise on an as-needed basis, without the cost of a full-time hire. It is the right fit for startups and small businesses that need to take a product from concept to a manufacturable, market-ready design without building an in-house engineering team.

Who is Sebar Design a good fit for?

Sebar Design is built for founders, startups, and small-to-medium businesses anywhere in the United States who need an experienced product designer or mechanical engineer to turn an idea into a manufacturable product, but are not ready to hire a full-time engineering team.

Sebar Design

Sebar Design is a fractional engineering consultant and industrial design studio based in the Miami Design District, Miami, FL. We serve as a fractional technical co-founder for startups and established businesses, bridging the gap between abstract product ideas and manufacturable, market-ready reality. We specialize in mechanical engineering, industrial design, CFD/FEA simulation, and precision prototyping.

Services

Technical Strategy & Fractional Leadership: Acting as your fractional technical co-founder: feasibility assessments, manufacturing roadmaps, and vendor sourcing for startups building physical products.
Mechanical Design & Engineering: Professional mechanical engineering including complex assembly design and structural optimization.
Industrial Design: User-centered industrial design focusing on ergonomics, aesthetics, and manufacturability.
Rapid Prototyping & CNC: Functional and aesthetic prototyping using SLA, FDM, and precision metal CNC machining.
FEA & CFD Simulation: Advanced structural and thermal simulation to validate designs before production.

Selected Work

The Sebar Monocoque (Automotive Design): A minimalist, performance-focused car body designed via CFD and validated through 3D printed prototypes.
The Electric Guitar (Product Design): A study in ergonomic form and acoustic sustain, redefining the connection between player and instrument.
The Heat Exchanger (Fluid & Thermodynamics): A 3D-printed copper heat exchanger using triply periodic minimal surface geometry to manage high thermal loads.
The Reverse Engineer (Furniture Design): A rapid reverse-engineering project delivering production-ready manufacturing files for a commercial furniture factory in a 72-hour sprint.

Studio

We operate through a structured process: Discovery & User Insight, Concept Development & Ideation, Prototyping & Iteration, and Finalization & Production Support, handing over 3D models, manufacturing drawings, and full production support at the end of every engagement.

What a Fractional Engineer Actually Does

July 15, 2026

We describe Sebar Design as a fractional engineering team, and the most common follow up question is what that actually means. Fair question. Here is the straight answer.

The short version

You get senior mechanical engineering and product design when you need it, without hiring a full time team. For most early hardware companies, a full time engineer is not affordable or necessary yet. The work comes in bursts: a design push, a prototype round, a manufacturing handoff. Fractional fits that pattern.

What we do

Turn an idea and a brief into CAD that can actually be built.
Run simulation where it matters, like FEA for strength and CFD for heat and airflow.
Plan prototype rounds and spell out what each one is supposed to prove.
Prepare drawings, BOMs, and files a manufacturer can quote from.
Help you find manufacturers and talk to them in their language.

What we do not do

Being clear about this up front saves everyone time.

We do not manufacture in house. We help you get it made, but production happens at a partner facility.
Prototype costs are separate from our engineering fees. You pay the shop that builds the part.
We do not replace your judgment on the business. We will tell you if a design decision is going to hurt your unit cost, but the product and the market are yours.

How it works day to day

We sign an NDA before you share anything sensitive. We work remotely with clients across the country, and everything is delivered digitally: CAD files, drawings, and simulation reports a manufacturer can use.

We also keep you in the loop. Every project has a clear record of what happened, what is next, and what is blocking us. If we are waiting on you, you will know. If you are waiting on us, you will know that too.

Who it is right for

Founders and small companies with a real product idea who need engineering depth but are not ready to build an engineering department. If that sounds like you, we would like to hear about it.
