About us

James Barr BSc (Hons) - 3D Product Designer

Follow us on Instagram 
to see our updated gallery.

Company owner James Barr BSc (Hons) established a limited company in 2014 to work directly with clients. With a network of trusted manufacturing partners James Barr Design has reliable links to both prototype and manufacture products.

James has been a consultant designer since 1999, working in a wide range of industries as both a consultant and in-house senior designer. Consultancy work requires the ability to research and quickly understand any products unique challenges and opportunities. Running in-house design teams requires great attention to detail for all aspects of a product launch including quality control, graphic design and packaging. 

We specialise in CAD product design in Surrey, London, Kent and Sussex but do take on clients across the UK and Europe. Communication is key for remote working; We make sure clients are regularly kept updated with progress through zoom meetings, phone calls and emails.

Research and development (R&D), and new product development (NPD) involve some iterative design work to solve practical, technological or scientific uncertainties. Through experience we work with our clients to make sure the service we offer is as effective and efficient as possible.    



"James managed a team of designers and technicians and was responsible for product design over a range of Audio Visual brands owned by Armour. An important part of his role was to ensure that projects were managed to time and budget which required extensive liaison with brand managers and manufacturers."
Dr Mark Collingwood
Director - Armour Home Electronics
"Reliable, trustworthy and responsible. He is creative and able to communicate his design concepts effectively through the use of 3D CAD and rendering software. Hard working, well organised and extremely personable having a natural ability to get on with everyone who came in contact with him."
Tony Lee
Owner - Lee Design Associates
"James has supported R'Care with both his creativity and technical ability to develop a family of new products for us. Working with European manufacturing partners he has developed attractive and economic products underpinned by a good understanding of our market requirements."
John Gough
Director - R'Care KFT

Experience and technology

Having worked since 1999 in product design and engineering we have a wealth of experience to draw from both in terms of manufacturing knowledge and aesthetics. We use the very latest 3D CAD systems (SolidWorks), and have in-house 3D printing and 3D scanning technologies.

Investment in rapid prototyping equipment and industry standard software means our design process is very efficient. We can develop concepts in a few days and in some cases can produce a working prototype in under an hour!.

We use the very latest version of SolidWorks to generate our 3D parts, assemblies and 2D control drawings. It can import legacy data from most common 3D file formats for reuse or as a reference.

SolidWorks is the industry standard software for designing and releasing information to prototyping and manufacturing partners. The 3D designs we create can easily be used by manufacturers for mass production.

Evaluation of physical prototypes using 3D scanning and in-house prototyping allows for fast iterative testing of components.

We have the in-house ability to create very large 3D printed prototypes up to 500x500x500mm. Printed models can be very precise holding dimensions less than 0.05mm.

Our software allows us to create both very precise geometric forms for engineering projects and smoother ‘organic’ shapes more suitable for ergonomic applications.
