Shaping liquids into space structures - microgravity-assisted design and manufacturing of minimal surfaces
Erez Hochman, Aaron Sprecher, Amos A. Hari +1
This work advances a fundamentally new approach to space-based construction by using liquid self organization in microgravity as a generative design and fabrication principle. Buil…
Zero-waste manufacturing of ophthalmic lenses by direct Fluidic Shaping in arbitrary domains
Yotam Katzman, Mor Elgarisi, Amos A. Hari +4
The conventional manufacturing of ophthalmic lenses is an inefficient subtractive process where up to 97% of the material is discarded through grinding, polishing, and edging. Flui…
Fluidic Shaping over arbitrary domains: theory and high order finite-elements solver
Amos A. Hari, Moran Bercovici
Fluidic Shaping is a novel method for fabrication of optical components based on the equilibrium state of liquid volumes in neutral buoyancy, subjected to geometrical constraints.…
Modeling the Thermal Behavior of Photopolymers for In-Space Fabrication
Jonathan Ericson, Daniel Widerker, Eytan Stibbe +15
Future long-duration space missions will require in-situ, on-demand manufacturing of tools and components. Photopolymer-based processes are attractive for this purpose due to their…
LiquiFab -- Building with liquids in weightlessness
Erez Hochman, Aaron Sprecher, Kateryna Suzina +4
Existing digital manufacturing methods can be broadly divided into subtractive approaches, where material is removed from a bulk to reveal the desired form, and additive methods, i…
In-space manufacturing of optical lenses: Fluidic Shaping aboard the International Space Station
Omer Luria, Mor Elgarisi, Eytan Stibbe +12
In-space manufacturing technologies are vital for enabling advanced space missions and addressing logistical limitations of space exploration. While additive manufacturing has prog…
