Prototyping by Stereolithography (SLA)

Stereolithography (SLA)

A tried and tested method to produce accurate 3D models with a range of material choices.

SLA ClearVueThis process has been widely implemented, and well proven, with a variety of different materials available. And Plunkett Associates should know; Tim Plunkett, having already established two pioneering additive manufacturing companies, has over 20 years experience in this industry and a wealth of knowledge and contacts as a result.

With feature resolution ranging from around 0.1-0.2mm (material dependent), and a maximum build envelope of 650x750x550, there are few designs that can’t be brought to life using Stereolithography (SLA).

A wide variety of resins are available, from all over the world, however many of them will only work in the machines they have been designed for. Materials have evolved to emulate commonly used plastics, such as ABS and polypropylene, with virgin parts displaying similar and in some cases superior properties to the materials they are imitating. This change in performance can result in many similar resins demonstrating your desired properties.

Composite-filled resins are also available for use in Stereolithography (SLA). These offer a large increase in stiffness, a moderate increase to mechanical strength and increased performance at higher temperatures; making Stereolithography (SLA) a high performance solution to your design needs. Due to the nature of the filler in the resin, components with high feature definition, and small passageways, may sometimes pose barriers to its implementation.SLA

Virgin parts give solid mechanical properties, however to get the highest performance from the resins, post curing in the form of UV and/or thermal treatment may be necessary.

Whilst deliveries are always tailored to customer requirements, a typical turnaround would be 5-7 days.

Plunkett Associates know it is imperatitve to choose the correct material for Stereolithography (SLA) in order to get the best results. With regular access to a large range of the latest resins and advanced processing platforms, Plunkett Associates can ensure that you make the right choice for your prototype part.
