Amalgam prototype modelmakers recently completed a set of prototypes for the Triggertrap Redsnap, an affordable timelapse and high-speed camera system funded through Kickstarter. Our vacuum cast prototype of the look-and-feel enclosure is one of many similar projects we have undertaken over the years, a list which includes the Gapgun, which we produce in batches as a fully functional production model. Our vacuum casting facility and hot new 3D printer enable us to offer a comprehensive prototyping service for a range of products, and our understanding of materials allows us to make these objects suitable for practical testing and ergonomics as much as look-and-feel display pieces.
Our method combines the reliability and speed of 3D printing and additive manufacture with craftsman-level hand skills to turn a stepped rough build into a fine-tolerance, exquisitely finished casting master. We are then able to make batch casts of this object to replicate its form, texture and tolerances in a range of materials appropriate to its application, for example durable enclosures or rubberised gaskets and facial seals. In some cases this has meant the casts are the final product, not a stage in the design process.
