The Selective Laser Sintering (SLS) process offers the capacity to create strong and durable, functional plastic prototypes for a wide range of applications. This process is self supporting allowing parts to be built within other parts with complex geometry, which could not be made in any other way. It is particularly well suited to under bonnet applications.
Like Stereolithography (SLA) the SLS process is a layer-additive processes building in layers from 3D data, but uses a hot laser to sinter the nylon powder. For form, fit, function and aesthetic evaluation, Frank R Hay & Sons produces a range of SLS models as a fast, cost effective method of proving CAD design before committing to your chosen production route.
SLS modelling offers the best rapid prototyping process for accurate models for form fit and functional prototype validation. With our Vanguard we can manufacture accurate prototypes, with a typical tolerance of +/-0.2mm per 100mm.

Advantages of SLS:
|
- Quick delivery.
- Direct Manufacturing.
- Parts up to 381mm x 330mm x 457mm high can be built in one piece.
- Multiple build option for low-volume production runs.
- Accuracy, not geometry sensitive. Can create very complex forms.
- Produce fully functional design / engineering verification models.
- Snap fits and live hinges.
- Strength approximate to 75% of an injection moulded nylon component
- High temperature and chemical resistance.
- Surface finishes available to make parts look like the production material.
- Excellent durability and wear characteristics.
- SLS process suits all manufacturing sectors.

Delivery and Finishing:
- 2-3 days for unfinished parts. (basic bead blast)
- 3-5 days for finished (Surfaces hand finished and if required sealed)
- 5-6 days for fully finished models. (Paint finishes in any colour and finish, gloss, spark, satin, matt).
