Five-axis printing is a young field with no centre — so this site is built to be one: plain-English guides to conformal, non-planar printing, a map of the technology routes and the people exploring them, a glossary, and an open research agenda. Underneath it sits our own work: a prototype-stage 5-axis FDM platform — machine, multi-axis controller and curved-surface slicer — developed since 2022 and built to order for research institutes, universities and advanced makers.
Search for "5-axis 3D printing" today and you mostly find machine-shop pages, a few papers and scattered forum threads. The guides below are our attempt at the missing reference layer — written from the workbench, kept honest about what is proven and what is still open, and open to correction from anyone in the field.
What "5-axis" actually means in printing, how non-planar slicing works, and the vocabulary the field uses — start with the two guides below.
Read the guides ↓ PATH BTilt-rotate tables, tilting heads, 3+2 indexing, belt printers, robotic arms, hybrids — how each route works, where it wins, and who is pursuing it.
See the landscape ↓ PATH COur prototype platform: the machine, the POCENDER / PCD3D controller with RTCP, and the curved-surface slicer — and how to get one or co-develop it.
See the platform ↓A printer earns the label when the nozzle and the part can be re-oriented relative to each other while printing — three linear axes (X, Y, Z) plus two rotary axes working together. The rotary axes can live in three places: in the table (a tilting, rotating trunnion), in the head (a swivelling nozzle), or split between both. Each choice changes the machine's stiffness, collision behaviour and usable volume.
A conventional slicer intersects the model with horizontal planes and emits flat perimeters. A non-planar slicer instead generates toolpaths on the part's surfaces: offsetting paths across the geometry, assigning each point a nozzle orientation (usually the surface normal), then checking the whole motion for collisions between nozzle, part and machine.
"Multi-axis printing" covers machines with very different ambitions. Trunnion-table FDM (our route) targets true conformal layers at bench scale. Tilting-head designs keep a big flat bed but fight head collisions. 3+2 indexing is the pragmatic middle. Belt printers add one endless axis for long parts at a fixed angle — useful, but not conformal. Robotic arms trade accuracy for metre-scale freedom. Print-and-mill hybrids buy surface finish with a machining pass, at hybrid prices.
For labs setting up a non-planar programme, the questions that save the most time are asked before any hardware arrives:
The whole site uses these words with exactly these meanings — here and in the full glossary.
A 3-axis printer can only stack horizontal slices, so every curved surface becomes a staircase and every overhang needs scaffolding. Add rotary axes and keep the nozzle normal to the surface, and the geometry rules change completely.
By tilting the part as it grows, walls and undercuts that would need support structures on a flat-layer machine print self-supported. No supports to design, print, break off and sand away — and internal, curved geometries that flat slicing simply cannot reach become printable.
FDM parts are weakest across layer lines. Conformal layers run along the part's surface — along the load path — instead of slicing across it, so curved shells, ducts and brackets behave more like the continuous material they imitate.
Layers that follow the surface eliminate the staircase finish on domes, tubes and freeform shells — the surfaces come off the machine smooth, with far less post-processing, which matters for airflow, fluid flow and anything that touches skin.
Five axes let you deposit onto curved, already-existing objects: add features to a printed or machined substrate, repair a worn curved surface, or print directly onto a shell. The substrate becomes part of the build — a research direction flat-layer machines can't explore at all.
The machine below is our current prototype: a fully enclosed benchtop unit with a tilting build stage, touchscreen control and our own multi-axis controller and slicer. There is no fixed catalogue configuration — every unit is built to order, and travels, hotend, sensors and software options are agreed with the buyer before we build.
Built for labs and serious workshops: an enclosed machine that prints true non-planar toolpaths with simultaneous five-axis motion, driven by our POCENDER / PCD3D controller and curved-surface slicing software.
Travel figures are the reference prototype's controller configuration; usable conformal volume depends on part geometry and tilt angles. Final specification of any unit is confirmed in writing before build — if your project needs different travels or sensors, that is a configuration conversation, not a problem.

A conventional FDM printer stacks flat layers and can only move in X, Y and Z. A 5-axis machine adds rotary axes, so the nozzle stays normal to the surface being printed and the layers themselves curve to follow the part — that is conformal, or non-planar, printing. Overhangs and undercuts print without support structures, curved shells come out smooth instead of stair-stepped, and material is laid along the surface, where the loads run, instead of across flat slices.
Not yet — and we would rather say so plainly. The platform is at prototype stage: every machine is built to order, configured with the buyer, and still evolving. It is not a mass-produced, lights-out production printer, and it rewards users who are technically engaged. If you need certified fleet repeatability today, this is not the right purchase yet. If you want to research, teach or push non-planar printing — and shape the machine while you do — this is exactly the stage to join.
Research institutes and university labs working on non-planar printing, multi-axis motion or slicing algorithms; teaching labs that want students on real five-axis hardware; and advanced makers and small studios who have hit the limits of flat-layer printing. Typical projects include conformal printing research, curved composite shells, printing onto existing curved parts, and custom machine or slicer development with us.
The current reference prototype is configured with axis travel of X 220 × Y 190 × Z 180 mm. The usable conformal volume is smaller than the travel box and depends on part geometry and tilt angles — send us your model and we will check it honestly. Custom builds can be specified with different travels.
A prototype machine, a custom build, a slicer collaboration, a research idea — or a correction to this hub: all of them start the same way.
