CADtec3D Consignments and professional summery
An accomplished independent Senior Design Engineer with experience within the Space and Scientific equipment industries operating within my own company CADtec3D Ltd.
CADtec3D is a service provider with extensive experience designing high precision devices using Mechanical, Opto-Mechanical and Electro-Mechanical Design expertise including modelling of complex Harness Assemblies to a portfolio of clients on a contract basis operating outside IR35. I have my own SolidWorks Premium license, currently using 2022. Adept at producing designs from a requirement specification to conceptual design to finally producing full detail drawings for production utilising more than 20 years’ SolidWorks experience.
Accustomed to using standards ISO 10110, DEF STAN 05-10 and BS8888 including Geometrical tolerancing is the normal standard for CADtec3D unless client specifies alternatives. Able to perform linear structural analysis to determine the extent of deformations under different loads and conditions to ensure adherence to design specifications. Extensive knowledge and experience using traditional and modern manufacturing techniques for small to high volume production runs using Stereolithography, Sand and Investment castings, Turning, Milling, EDM, Wire Erosion and prefabricated (welded) components. CADtec3D has invested in 3D printing technology of the FDM (fused deposition modelling type) with a wide range of thermoplastics and colours and can offer samples of components for evaluation purposes or small batch production runs dependant on size. Can help and advise on getting that “sweet spot” method of manufacturing to minimise investment and maximise profit dependant on your initial required production requirements.
With excellent communication skills, a very analytical approach to everything done regarding problem solving, and many years design experience, I look forward to helping you achieve your company goals and aspirations.
CADtec3D Ltd (Design Consultancy) June 2023 to date
Completed a novel design for an Airsoft Sight that uses an L.E.D. instead of a fibre optic. The L.E.D. has a choice of 2 intensity levels that overcomes the necessity of having to use relatively bright ambient light when using conventional fibre optic sights. The Sight interfaces with a Picatinny Rail.
The design was modelled using SolidWorks 2022. The main Sight body is 3D printed after being optimised for a happy medium of speed, surface quality and material usage using PrusaSlicer software. In addition, I have invested time producing CADtec3D’s comprehensive website that includes visuals and examples of previous designs worked on for various industries.
and similarly an "online version" of this CV which contains detailed information with visuals & examples of my areas of expertise which includes Mechanical Design, Modelling of electrical harnesses, Opto-Mechanical Design, Photo Realistic Images, Animation and Graticule design (external ballistics), for armoured fighting vehicles.

Sagentia Innovation Ltd (a division of the science group) ~ contract outside IR35
Mechanical Engineer (May 2021 to date)
Working within a large Team of Engineers on a innovative Medical Robot. My contribution to the overall project was Designing and detailing a drive unit that controls the dextrous / nimble part of the robot / patient interface. I am restricted by an NDA preventing me sharing technical information in detail, but the drive unit was a highly complex electromechanical engineering task. Working to a very tight tolerances budget as a result of a tolerance analysis through the whole system. Working within International Standard IEC 80601-2-77 (medical electrical equipment), detail drawings conformed to BS8888 with full GD&T implementation using SolidWorks 2019.
Beck Optronic Solutions Ltd ~ contract outside IR35
Opto-Mechanical design engineer (August 2020 to May 2021)
Designing and detailing the main structure and components parts that produce a “state of the art” Electro, Opto-Mechanical Device (Space Satellite). This was achieved working from a Zemax prescription and a diagram of the allowable footprint (space claim). Expertise required to accomplish this is having the ability to house precision optics in a confined, predefined footprint whilst being able to access all the internal component parts for assembly and fine adjustment. Engaged to ensure the C of G (centre of gravity) was in a very tightly tolerance zone and the overall mass had to be adhered to which meant investigating the use of some exotic materials to meet specification after structural analysis. A key aspect of the functionality of this device is having the ability to focus a primary lens remotely using a stepper motor, whilst maintaining collimation to an extremely high degree of concentricity with the main collimating assembly. That was achieved by using a precise linear stage driven by an ultrasonic piezo motor. All components including optics were Designed and detailed using SolidWorks 2017.
CADtec3D Ltd (Design Consultancy)
Opto-Mechanical Design Engineer (May 2020 to August 2020)
Leading the design of a range of Sighting systems for clay pigeon enthusiasts, focusing on the elimination of the problem associated with cross-eye dominance, including two versions one machined from an aluminium extrusion as well as creating a 3D printed version to minimise weight and cost. Key Achievements: Devised opto-mechanical devices for an armoured reconnaissance vehicle, surveying the vehicle and crafting conceptual designs illustrating the required field of view from a specific head position. Developed all models required to produce parts utilising Stereolithography (3D printing in house) along with prefabrication of prisms by filling “optically clear Perspex prisms” with oil that simulated the production glass’s refractive index. Created design specifications and delivered presentations to immediate clients and end-users on technical matters. Conducted linear finite element analysis to determine acceptable levels of deformation and stress that the product could see in the environment.
Edinburgh Instruments ~ 3rd contract outside IR35
Mechanical Engineer (Oct 2019 to May 2020)
Providing Mechanical Design consultancy services on a wide range of Opto-Mechanical scientific instruments. Designing product improvements to existing designs.

I have transformed 2 prototype units into robust designs ready for sustained batch production using SolidWorks 2019. Specific areas such as Functionality, Aesthetics, Ease of Assembly / Serviceability, cost effective production methods and survivability (use in harsh environment) were all considered and implemented. Complementing the core design was a requirement for a custom Opto-Mechanical alignment jig in order to collimate the camera and laser assemblies which bring each axis to a point of coincidence at a specific pre-determined distance to a very high degree of accuracy. This was a modular design that can be used on any variation of the 2 Sensor Configuration.
