I am Richard Tegelbeckers, designer of the DeltaTrix 3D printer. The design for the initial prototype has been published on Instructables with over 80000 views and over 700 'likes' so far: http://www.instructables.com/id/DeltaTrix-3D-Printer/
The current information on Instructables is sufficient to re-create my first prototype, with more updates to follow soon. Anyone interested in making a printer from scratch is welcome to use the Open Source
plans already published. Alternatively, the printer is now available as a kit on crowdsourcing platform Kickstarter: http://kck.st/1i6fQ6w
The printer is not trying to be the cheapest around, but is aimed at satisfying the requirements of the more demanding maker and the professional design engineer. It is very fast, very accurate, made to last, and designed to inspire. Thanks for your attention, and may the (Open) Source be with you!
