RAPID PROTOTYPING

Currently a managed service with our selected business partner extending our traditional Prototyping and Development service we now provide three dimensional parts produced direct from CAD data. The advancements in technology mean that you can now not only have a part in your hand within a week of finished model data being available but that part can be of a material that will enable it to be tested for both fit and function.

There are two main advantages that this service can deliver for our customers: -

1. Confidence that the part designed will be right visually and functionally before moving to production tooling.
2. Early promotion of a product; therefore, the payback on your investment can start at a much earlier time.

Concept Modelling

With a lead time of 3 to 4 days this is the most basic form of Rapid Prototyping. The parts are built up in layers using a fine powder and binder before being impregnated using either a wax or resin to improve the strength. These concept models can provide a designer with a basic 3D model in their hand at an early stage of the project.

SLA

Stereo Lithography (SLA) is a widely used technique. Models are produced in a transparent epoxy resin, initially cured layer by layer with an ultraviolet laser. There is then a second post curing operation required. These parts can usually be supplied in 5 to 7 days. When cosmetic finish is important the parts can be sanded and painted as required but they do need to be handled with care as they remain relatively brittle.

SLS

Selective Laser Sintering (SLS) differs from SLA models in that it can deliver complex, durable and functional products. These parts can usually be supplied in 5 to 7 days. Components are created from 3D data by a laser fusing thin layers together to form a solid object. Parts are usually supplied in Nylon, GF Nylon or Stainless Steel although more material options are becoming available.
