Design & Engineering

At D Squared we have invested heavily in software, equipment, and staff training to ensure we're able to apply the very latest in design and engineering techniques to the development of our clients' products and medical devices.

Our design and engineering capabilities include:

  • Concept Generation & Presentation Sketching

  • Computer Aided Design (SolidWorks & Creo)

  • UI & UX Design

  • Photorealist Rendering (KeyShot)

  • Finite Element Analysis (SolidWorks Simulation)

  • Instructions for Use (IFU) Development

  • Characterisation & Usability Studies

  • Technical Report Writing 

  • Reverse Engineering & Competitor Analysis

  • Intellectual Property (IP) Generation & Capture



Alongside these techniques, D Squared utilise a wide range of materials and processes for the production of both visual and working prototypes.

Our in-house prototyping capabilities include:

  • High Resolution 3D Printing (SLA)

  • Large Format 3D Printing (FDM)

  • Laser Cutting

  • CNC Milling 

  • Vacuum Forming 

  • Silicone Casting

  • CNC Cutting Plotter 

  • Manual Milling & Turning

  • Extensive Model Making Tools

In addition to these capabilities, we work closely with a trusted network of partners to provide additional prototyping processes, from sheet metal forming to vacuum casting and rapid tooling.

Testing &


Being able to characterise and/or verify the performance of products and medical devices is an essential part of the development process, which is often left until the final stages of the project. At D Squared we believe it is essential to thoroughly test each iteration of the design before moving onto the next phase of the project, and we have invested in a wide range of test equipment and software to support this.

Our test and verification capabilities include:

  • Force & Torque Measurement

  • Ingress Protection (IP) Testing

  • Pressure & Flow Rate Measurement

  • Calibrated Measurement Instruments (Balances, Timers, Thermometer/Hygrometer, etc.)

  • Acoustic Analysis (SPL & FFT)

  • Metrology 


Industrialisation & Production Support

Like testing and verification we believe that the process of industrialisation should be integrated into the development process from the outset and we're able to provide a range of services to ensure a trouble-free transition into production.​

Our industrialisation and production support capabilities include:

  • Manufacturing Specification Preparation

  • Tolerance Analysis

  • Design for Manufacturing & Assembly (DfM&A) Assessment 

  • Injection Mould Tooling Procurement

  • Verification & Validation (ISO 13485 Compliant)

At D Squared we have extensive experience in the industrialisation of products and medical devices for both batch and volume manufacturing, having worked on projects with annual production volumes varying from 1,000 to 1,000,000 units.


Electrical & Electronics Engineering

Combining our in-house capabilities with those of our trusted local partner, D Squared are able to offer a full range of electrical and electronic engineering capabilities including:

  • Arduino & Raspberry Pi Prototyping

  • IoT & Sensor Integration

  • Electrical Control Systems

  • PCB Development & Manufacture

  • Firmware & Software Development

  • Test & Validation

  • Contract Electronics Manufacturing (CEM)

This enables us to develop products and medical devices which seamlessly integrate electrical/electronic and mechanical systems.

Services (Patent Application & Regulator

Patent Application & Regulatory Submission Support

At D Squared we're dedicated to ensuring that your development journey is not only innovative, but also compliant with all relevant regulatory standards. From working in conjunction with patent attorneys to preparing regulatory submissions, we’re able to offer a broad range of services including:

  • Patent Claims & Technical Illustrations

  • Design History File (DHF) Documentation

  • Risk Management (ISO 14971 Compliant)

  • Usability Engineering (IEC 62366 Compliant)

Whether you need assistance in navigating complex regulatory landscapes, creating accurate patent illustrations, or implementing robust risk management strategies, we're here to support you. 



Established in 2012, D Squared Product Development is a Liverpool-based SME that offers product development, design and engineering consultancy services, to clients across the consumer, medical and industrial sectors.

We enable individuals, universities, hospitals, and new technology start-ups to bring innovative new products and medical devices to market, as well as supporting established manufacturers looking to improve on their existing ranges, and/or outsource elements of their development process.

With experience in both consultancy and manufacturing environments, our multidisciplinary team has gained extensive knowledge of the entire development process, from early-stage research and development activities to industrialisation and production scale-up.

Located in the UK but serving clients internationally, we are happy to offer a free consultation to discuss your development requirements further.
