Unlocking Geometry with Inkbit Vista™
Manifolds are complex parts that require several levels of expertise to optimize. At Inkbit, we are optimizing the manufacturing of manifolds that finally unlock the geometric freedom of additive manufacturing.
Manifold Design Today
There is a problem in the industry today: engineers want to be able to design and manufacture fluid manifolds that are optimized for flow. The existing methods of manifold fabrication place major constraints on channel geometry. This makes it very difficult to optimize and places additional engineering burden on the equipment design. Additionally, the fluids used in these manifolds are frequently corrosive, requiring that the manifold material be made of a chemically resistant material. Engineers want a solution that provides geometric freedom while maintaining the excellent chemical resistance of existing fabrication methods.

Inkbit Vista™, providing new tools for designers
While many may think Inkbit Vista™ is just for the production floor, it provides new tools for product design and development. To illustrate, let’s look at the designed manifold printed with Inkbit Vista™ (see Figure B). This is a part we made for one of our clients. The client had an elaborate aluminum fluid manifold used to pump and circulate fluids. The client was looking for a way to improve efficiency and to reduce the driving pumps’ power loss.
We were able to design a chemically resistant manifold that not only met our client’s requirements, but also improved the fluid dynamics, reduced weight, and cut down lead time by 15x. Our design takes advantage of generative design, while maintaining the production level properties that make it appropriate for its intended application.
