JENI<\/strong> doesn’t look like a 3D printer. It’s a tower, lit from within by a deep red glow, modular sections stacked and racked like server infrastructure. <\/span>Add a module and it grows. Reconfigure a node and it takes on a new process. A single install can produce hundreds of thousands of parts a day and in some cases, more than a million.
\n<\/span><\/p>\n

Photocentric<\/strong> launched JENI as an autonomous production platform that pairs high-resolution LCD 3D printing<\/a> with robotic post-processing to manufacture plastic parts at volumes and costs the UK company says compete directly with injection molding.<\/span><\/p>\n

It\u2019s Time to Use 3D Printing for Mass Production<\/h2>\n

Additive manufacturing is known for being excellent for prototypes, and for complex or bespoke components, but never for the parts that the world runs on: the clips, caps, connectors and grommets made in the millions. Photocentric argues that the idea is now outdated, and that additive’s failure to compete with injection molding at volume was not about the printing itself, but about labor, part handling, batch inconsistencies, and material cost. <\/span>That\u2019s why JENI is designed to run continuously and unattended, with every job carrying its own process parameters.<\/strong>

With this high degree of automation, JENI removes the labor cost. Take the example of stand off spacers: a single module can produce 238,000 spacers per day, at a cost of less than $0.02 each. That makes material the primary expense, and users can print with the resins Photocentric formulates itself, or whatever 405nm materials they prefer.<\/span><\/p>\n

How JENI works<\/h2>\n

Photocentric describes JENI plainly as “injection molding without tooling.”<\/strong> It automates production using high-resolution LCD 3D printers and post-processing nodes connected by high-speed robotics. A customer can start with a single robotic control and one process module, then add modules as production scales.<\/span><\/p>\n

A digital file sent to JENI carries the print instructions as well as the full sequence of post-processes, like wash and cure time. JENI monitors every node, assigns the job to the next free one that matches its requirements, and a gantry collects the appropriate print platform and moves it into position. Because every job is treated as unique, JENI can run different geometries and post-processing sequences in the same batch, and apply machine learning to optimize a job for cost, speed, carbon footprint, or quality.<\/span><\/p>\n
