The purpose of Geometer becomes apparent when you realize its simplicity: [David Troetschel]’s project is to create an easily understandable design tool that encourages goal-oriented design. The kit comes with physical components and digital counterparts that can be combined in a modular way. They each have a specific geometry, which provide versatility while keeping manufacturing simple.
For the prototyping phase, small snap-on parts 3D printed on a Formlabs printer mimic the module components on a smaller scale. Once a design is conceived and the Geometer Grasshopper program finalizes the module arrangement necessary for the model, the larger pieces can be used as a mold for a concrete or hydrocal mold casting.
The present set of modules is in its seventh iteration, initially beginning as a senior thesis for [Troetschel]. Since then, the project itself has had an extensive prototyping phase in which the components have gone from being injection-molded to 3D printed.
The overall process for prototyping is faster than 3D printing and more cost-effective than sending to a third-party shop to build, which adds to the project’s goal of making manufacturing design more accessible. This is an interesting initiative to introduce a new way of making to the DIY community, and we’re curious to see this idea take off in makerspaces.
