We haven't updated in awhile as things have slightly changed on how we are going to produce these two models. Although we would have loved to have continued to pursue making the housings in metal via CNC the shape and structure pretty much ruled out any cost effective CNC option. Even going the route of metal injection mold the cost was just prohibitive and there was no guarantee we would get the results we wanted.
We were about to go back to the drawing board and go for a more traditional, easier CNC machined design, when we choose instead to invest in very high resolution 3D printer, machines which can churn out prints that are 1:1 like anything made in a plastic injection mold, expect they are able to make our intricate shapes and and less restriction in design (nor imagination).
Although the 3D printing option was new, the idea that we would make these two models in house rather than use a contract manufacturer is still staying true. Our new workshop is kitted out and running, these two models and many to come in the future will be made in house, this allows us to control the quality far, far better.
