The gravity-defying future of manufacturing | Schendy Kernizan

3D printing promised to reinvent how we make things, but it's mostly stuck producing prototypes with a high level of waste. Designer and TED Fellow Schendy Kernizan found a different way — by printing objects directly into a tub of gel. He explains how this technique eliminates the constraints

Episode Summary

Executive Summary: Skendi Kernizan explains Rapid Liquid Print, a manufacturing method that prints objects inside a reusable gel to suspend them in space, reducing supports, waste, and shape limits. The conversation explores his Haiti-rooted maker mindset, a personal drive for softer custom-fit products due to his club foot, the company’s current applications in medical, automotive, consumer, and robotics sectors, and the long-term vision of mass customization and new manufacturing possibilities beyond Earth.

Main Topics: Gravity-free manufacturing inside gel (Priority: 5/5): Kernizan describes a process that lets materials be printed inside a gel bath, eliminating the need for molds and support structures while enabling complex soft parts to retain shape during curing. Limits of conventional 3D printing and molding (Priority: 5/5): He contrasts Rapid Liquid Print with standard 3D printing and injection molding, arguing that existing methods are strong for prototypes or high-volume identical parts but weak for soft, customized, or low-volume production. Customization for the human body (Priority: 5/5): Kernizan connects his personal experience with club foot and rigid braces to a broader belief that products should conform to bodies rather than force bodies into standardized forms. Origin story and maker mindset in Haiti (Priority: 4/5): He credits growing up in Haiti, around construction and improvisation, with teaching him to build creatively from limited resources and to see making as an adaptive, practical skill. Failure, persistence, and startup realities (Priority: 4/5): Kernizan emphasizes that innovation emerges through many failures, and that the hardest obstacles often include hiring, funding, and long development cycles rather than just technical problems. Current and future applications (Priority: 4/5): The technology is already being explored for seals, gaskets, wearables, soft grippers, consumer products, robotics, and medical devices, with a long-term vision that could extend to space manufacturing and habitats. Advice for aspiring makers (Priority: 3/5): He encourages curiosity, bravery, and willingness to try unfamiliar things, telling listeners to begin before they feel ready and to approach learning with a childlike willingness to experiment.

Key Arguments: Traditional manufacturing relies too heavily on molds, standard shapes, and support structures, which creates waste and limits customization. 3D printing is useful, but it still depends on a build platform and struggles with complex geometries, soft materials, and production-scale needs. Printing inside a gel allows objects to be drawn in space, held in place, and then cured, making the process more flexible and reusable. The gel-based method reduces waste because supports are unnecessary and the gel can be rinsed and reused. Mass customization should become accessible not only for niche medical needs but for many consumer and industrial uses. Kernizan’s background in Haiti and his personal experience with a club foot shaped his attraction to flexible, body-conforming materials. Innovation is not a single breakthrough but a long sequence of experiments, failures, and incremental discoveries. The company’s near-term mission is to solve factory problems that current manufacturing methods cannot solve, rather than targeting hobbyists. The technology is best suited to soft materials and geometries that do not require solid blocks or sharp 90-degree corners. Future manufacturing may enable entirely new products and environments, including space applications.

Pivotal Quotes: "If I have an idea in my mind and I have a pencil, can I draw it in space and then have that shape there?" — Skendi Kernizan: He uses this analogy to explain the gel-based printing process. "People often imagine that, you know, innovation is like one big breakthrough and you're done. But in reality, that journey is really created from thousands of different failures along the way." — Skendi Kernizan: He reflects on the reality of building a new manufacturing technology. "Have fun and be brave." — Skendi Kernizan: The advice he says he gives his daughter and would extend to aspiring makers.

Implications: The episode suggests manufacturing may shift toward flexible, reusable, body-specific production, especially for medical and industrial soft goods. It also reframes innovation as persistence-driven and accessible to anyone willing to experiment.
