There’s a good chance you’ve heard of five-axis machining before, especially in aerospace or advanced manufacturing, but now that same concept is starting to make its way into the world of 3D printing. And honestly, this could become one of the biggest shifts in how makers design and print parts in the future.
At a recent event, we stopped by the Unlayered 3D booth to check out a working five-axis 3D printer, and this wasn’t just another modified printer with a gimmick attached to it. This machine was doing things that traditional three-axis printers simply struggle with, especially when it comes to supports, surface quality, and printing complex geometry.
What Is Five-Axis 3D Printing?
Most desktop 3D printers today are considered three-axis printers. That means the printer moves in the X, Y, and Z directions while printing layers stacked on top of each other.
Five-axis printing adds additional rotational movement. In the case of the Unlayered 3D printer, both the print bed and the print head can rotate while still moving in traditional X, Y, and Z directions.
That means the printer is no longer locked into printing everything flat layer by layer in one orientation. Instead, it can reposition the part and the nozzle dynamically during the print process.
The result is a completely different approach to additive manufacturing.
Printing Without Supports
One of the biggest advantages of five-axis 3D printing is the ability to dramatically reduce — or even eliminate — supports.
Traditional FDM printers often need supports for overhangs, bridges, internal channels, or complex angles. Those supports waste filament, increase print times, and usually require post-processing after the print is finished.
Unlayered 3D demonstrated parts that were printed with no supports at all, even on geometries that would normally be difficult on a standard desktop printer.
That’s where things start getting really interesting for makers.
Instead of designing parts around the limitations of gravity and layer orientation, you can start designing around the actual function of the part itself.
Better Surface Finish
Another thing that immediately stood out was the surface quality of the prints.
Traditional FDM prints often show visible layer lines and banding, especially on curved surfaces or angled geometry. Because five-axis printing can continuously reposition the part during printing, it can create smoother transitions and cleaner surface finishes.
The prints looked significantly more refined compared to what you would normally expect from a standard layer-by-layer process.
For cosplay makers, prop builders, RC enthusiasts, and functional part designers, that could mean less sanding, less filler, and less cleanup overall.
Complex Internal Geometry
Internal geometry is another area where five-axis printing could completely change how parts are designed.
One example shown was an intake manifold-style print with internal channels that would normally require difficult-to-remove support structures on a standard printer.
With traditional three-axis printing, cleaning out supports inside enclosed spaces can be almost impossible without damaging the print. Five-axis printing allows the printer to approach geometry from different angles, making those internal structures far easier to produce cleanly.
That opens the door for more advanced airflow systems, ducting, robotics components, and engineering-focused designs.
TPU Printing Gets Even More Interesting
Flexible materials like TPU are already popular with makers, but supports on TPU are notoriously frustrating.
They can fuse too aggressively, become difficult to remove cleanly, and often ruin the final surface finish.
Unlayered 3D showed a TPU part being used on a robot that was printed entirely without supports. Seeing flexible material printed in complex geometry without support cleanup was honestly one of the most impressive parts of the demo.
For makers working on wearable projects, robotics, RC cars, custom grips, or flexible functional components, this could become a huge advantage.
The Software Side Matters Too
Of course, hardware is only half the battle.
Unlayered 3D also developed a modified slicer based on Orca Slicer called Unlayered Slicer. Right now, the slicing process still requires some user input when defining planes and orientations, but the long-term goal is to automate much of that process.
That’s important because five-axis printing introduces a whole new level of complexity compared to traditional slicing.
If companies can simplify that workflow enough for everyday makers, five-axis printing could eventually become far more accessible than many people expect.
Is Five-Axis 3D Printing Ready for Makers?
Right now, five-axis 3D printing still feels experimental in the maker space. The technology is clearly advancing quickly, but it hasn’t reached the plug-and-play simplicity most hobbyists are used to with modern desktop printers.
That said, the potential is enormous.
Less support waste, cleaner prints, improved TPU printing, smoother surfaces, and more advanced geometry all solve real problems makers deal with every day.
And honestly, this feels less like a small upgrade and more like a completely different philosophy for how 3D printing could work in the future.
Five-axis 3D printing may still be early for makers, but it already shows signs of where desktop manufacturing could be heading next.
For years, the focus in desktop 3D printing has mostly been about speed. Faster Benchys. Faster accelerations. Faster layer times.
But five-axis printing shifts the conversation toward something different: making better prints.
And that may end up being the bigger revolution.
