Trusted by Founders Who Are Serious About Going to Market
Proof of execution across markets.
Designed, engineered, prototyped, and stress-tested for mass production and market launch.
World’s First Handheld Human Heat Sink Device - $58K+ Raised
Developing a CNC-manufactured product from a rough hand-drawn sketch, raising $58,000 on Kickstarter.
Beer Can Holder for Ski & Snowboard Helmets
Fully tested, injection-molding ready manufacturable design, prepared in just 30 days from product concept.
Pillow for Recovering from Shoulder Pain & Surgery - $4.8M+ in Sales
Ergonomic consumer product, taken from foam prototype to a design that has helped 30,000+ post-op patients in the US.
The unfair advantage of an engineering-first product studio.
Mechanical engineers, industrial designers, electronics specialists, and an in-house prototyping lab, so your product gets built right from the design stage.
Hold it before you manufacture it
We 3D print and test in-house so every fit, mechanism, and dimension is validated on a real physical object. No outsourcing.
Parallel execution, no idle time
SolidWorks modeling, PCB layout planning, and DFM optimization all run in parallel across our engineering team.
Watch it come to life in real-time
Regular video updates from the engineers actually working on your product, to keep you involved in every design decision.
Documented for manufacturers
Technical drawings, BOM logic, material specs, assembly notes, all handed off, so the manufacturer starts work right away.
Hear from Founders Who Watched Their Vision Come to Life
"The 3D Cube team exceeded our expectations. They rapidly produced a well-made MVP of our LSR silicone sleeve for climbing quickdraws, communicated clearly every day, and shared short videos to explain their decisions and progress. Their proactive feedback and thoughtful challenges helped improve the design faster than we expected. We're very happy with the outcome and highly recommend them for rapid prototyping and product development."
"Working together has been an absolute pleasure. The team not only completed every task quickly, accurately, and reliably, but also took the initiative to think ahead, suggest improvements, and solve issues before they even appeared. Communication was always clear and professional. Deadlines were met, quality was consistently excellent, and the final results exceeded our expectations."
"I brought the 3D Cube team on for the initial research and assessment phase of a baby-product design project. They're meticulous, communicative, and incredibly reliable. It's been a great experience collaborating with a team that takes pride in their craft. Highly recommended."
"I had an excellent experience working with the 3D Cube team. Despite a very tight deadline, they delivered everything without compromising on quality. Their professionalism, attention to detail, and dedication truly stood out."
End-to-end product development partners.
For teams that need speed, stability, and scalability without juggling five different vendors.
Concept Validation & Direction
Our engineering team reviews your product idea, checks feasibility, identifies technical risks, and comes back with concept directions and a cost estimate.
CAD Development
Your product starts to take shape in SolidWorks, with structure, fitment, assembly logic, and mechanical systems all engineered for real-world performance.
Prototype & Testing
STL files prepared and printed in our in-house lab. The prototype gets physically tested for fit, function, ergonomics, and assembly. Because what looks right in CAD doesn't always work in your hand.
Minimum Viable Product
Physical MVP shipped directly to you after design refinements. We can also run a small batch of 25–100 units at MVP quality, with packaging design and branding support if needed.
Manufacturing Package
DFM-optimized CAD, technical drawings with tolerances, STEP and native SolidWorks files, manufacturing notes, and supplier handoff support, along with manufacturer referrals.
Optional Electronics & Hardware Integration
For IoT devices, smart products, and electronics-based hardware, our electronics specialists run in parallel with mechanical design. Handling component selection, PCB layout, firmware, open-bench testing, and full ECAD-MCAD integration.
