Prototypes

 
At Spraytech the emphasis is on quality of finish and we try to mimic the intended production item as closely as possible.  We can apply a range of surface finishes and special techniques to rapid prototypes produced by SLA, SLS, FDM and LOM.

We take our commissions from client end users, RP bureau and universities.
  

We believe our blend of new technologies, and the traditional skills of painting and hand finishing, provide some of the best prototypes and models.

 We can mimic almost any surface finish including most injection mouldings, from spark to wood grain.
The following series of pictures show the transformation of an AP Racing brake calliper starting from the excellent and detailed SLA made by the DERA at Farnborough. (Click pictures for larger images).

The first stage is to remove as much build evidence from the SLA as possible, without taking away details.  At this stage, dimensions are checked and allowance is made for paint build up.

Then, the first covering of paint is applied.  This makes it far easier to see the form of the model and shows areas that require rebuilding.  Once the form is right, the base colour can be applied.  In this example of the calliper it was to be a metal casting.

Matching the finish of an AP Racing Calliper called for some special effects.  Some features like bolts and bleed nipples were replaced with manufactured parts for added realism.
