“The shortest possible development and delivery time for this model was very important,” said Jonas Sandwall, Project Manager at Prototal AB. “The time to market schedule for this new infra-red camera was very tight so to produce the precise, highly detailed models the customer wanted, stereolithography technology was the only option.”

Protoal specialises in the production of highly detailed prototypes and functional models using stereolithography (SL) technology, selective laser sintering (SLS), vacuum casting (PUR) as well as serial part production from milled tools.

Prototal AB provides a full SL model development and production service to customers, delivering a fully functional prototype from original CAD data provided by the client. In this particular application, the prototype parts were produced in an SLA^® 5000 SL apparatus using Huntsman’s RenShape^® SL 7810 photopolymer.

RenShape^® SL 7810 is one of the latest SL photopolymers from Huntsman, designed to create prototype models and parts with improved overall functionality. These durable parts have high impact strength together with long term dimensional stability, even under conditions up to 40^oC and 90% humidity.

This makes them particularly suitable for the field testing and customer approval systems required by applications such as the FLIR infra-red camera. The model it produces has a good surface finish with fine detail.

“The models we produced for FLIR using RenShape^® SL 7810 successfully completed a range of internal assembly and functionality tests as well as going for final customer approval,” concluded Mr Sandwall.
