Photocentric has unveiled a high-speed 3D printer designed for area. Dubbed the CosmicMaker, this machine was constructed to fabricate parts instantly in orbit, giving astronauts a brand new stage of self-sufficiency. If this expertise takes off, it may redefine how we take into consideration in-space manufacturing.
The CosmicMaker is the most recent innovation from this UK-based firm specializing in liquid crystal show (LCD)-based resin 3D printers and photopolymer supplies. What makes the brand new area machine stand out is that it’s constructed to function in microgravity, turning liquid resin into stable elements utilizing mild.
Photocentric introduced the CosmicMaker in 2023 to deal with the rising want to assist area missions use fewer sources, run extra easily, and rely much less on assist from Earth. The corporate has already constructed a working model of the printer and examined it within the lab underneath simulated microgravity situations by rotating the system to watch resin conduct from a number of angles. The subsequent step will in all probability be testing the printer throughout parabolic flights, which create quick moments of weightlessness to see how properly the machine works in actual space-like situations.
Photocentric hasn’t mentioned precisely when it can launch the printer, however since they’re working with the European Area Company’s (ESA) In-orbit Manufacturing Accelerator, a program set as much as assist firms construct tech for area, it appears to be like like they’re planning to ship it to the Worldwide Area Station (ISS) sooner or later.

Why Construct a 3D Printer for Area?
Sending tools and spare elements to area is extremely costly and takes time. Since 2021, the price to move one kilogram of cargo to the ISS was roughly $20,000. This quantity has elevated from earlier years; for instance, in 2019, NASA charged $3,000 per kilogram for upmass (cargo despatched to the ISS) however revised its pricing coverage in 2021 to mirror full reimbursement for the worth of NASA sources. These excessive prices are a glimpse into the monetary challenges of resupply missions and spotlight the potential advantages of in-space manufacturing options.
Along with the 1000’s of {dollars} of launch prices, ready for a resupply mission isn’t at all times an choice. Cargo resupply missions are scheduled months prematurely, with little room for flexibility. If astronauts want a crucial device or substitute half, they typically have to attend for the subsequent launch, which could possibly be weeks or months away.
Even when a mission is scheduled, launches could be delayed as a result of climate, technical failures, or mission precedence adjustments. The scenario turns into much more crucial for deep-space missions, the place resupply flights may not be potential in any respect. Because of this having a 3D printer like CosmicMaker onboard may make a giant distinction, letting astronauts print what they want, after they want it, with out relying on Earth.
The CosmicMaker is a resin-based LCD 3D printer constructed to work in microgravity. It makes use of mild to remedy liquid resin into stable elements, permitting for extremely detailed and sturdy prints, which is right for mission-critical parts.
What Makes CosmicMaker Completely different?
Relating to working in area, there are a number of key issues that set CosmicMaker other than different 3D printers. To this point, most space-based 3D printers have used filament extrusion to make plastic elements. This expertise has been the go-to strategy for in-orbit manufacturing aboard the ISS since 2014, with units like the unique Made In Area (now Redwire) printer, the Additive Manufacturing Facility (AMF), and the Refabricator all counting on it.
CosmicMaker, however, takes a distinct strategy, utilizing LCD-based resin printing. This methodology is compact, energy-efficient, and far sooner. Not like FDM, which requires excessive warmth to soften the filament, LCD resin printing makes use of mild to remedy liquid resin into stable shapes. In a spacecraft, the place power effectivity and managed environments are crucial, avoiding pointless warmth technology is a giant benefit, explains Photocentric.
Printing with liquid resin in area is a novel problem as a result of fluids behave unpredictably in microgravity. With out correct containment, the resin may drift round, making a sticky, floating mess. CosmicMaker solves this concern with a sealed, dual-chamber system that “retains resin circulate secure.” This ensures the fabric stays precisely the place it must be, permitting astronauts to print exact and practical elements with out worrying about stray droplets interfering with any tools.
Velocity is one other unbelievable function of the CosmicMaker. Photocentric claims the printer can produce as much as two tonnes of plastic elements per day. Whereas it’s unlikely to succeed in that quantity in a microgravity setting, the effectivity of this technique may make it a necessary device for printing spare elements, instruments, and mission-critical objects on demand.
Photocentric is working with the European Area Company (ESA) to speed up in-space manufacturing. The corporate is a part of ESA’s Enterprise in Area Development Community (BSGN) In-orbit Manufacturing Accelerator, an initiative targeted on creating applied sciences to assist sustainable area missions.
Past easy plastic elements, Photocentric can also be exploring methods to print complicated silicon carbide parts in area. Silicon carbide is robust, light-weight, and may deal with excessive temperatures and radiation, making it ultimate for area environments. If astronauts may make these elements in area, it could open the door to constructing high-performance methods for satellites, area telescopes, and even future Lunar or Martian habitats with out ready for half supply from Earth.

CosmicMaker is a component of a bigger motion to create space missions extra impartial from Earth. As firms like Photocentric refine these applied sciences, we’d see complete factories in area able to constructing every thing from instruments to spacecraft parts.
