About 3DPrintRanker
The figure that decides whether a print finishes tonight or tomorrow is how many cubic millimetres of plastic the hotend can melt in a second, and it is almost never on the box. What is on the box is how fast the toolhead can move with nothing coming out of it. This catalogue converts one into the other for every machine whose maker publishes the flow rate, and says “not published” for the 34 that do not.

Millimetres per second is a motion spec, not a throughput spec
A gantry rated to 1000 mm/s can only lay a line that fast if something is feeding it. One millimetre of travel at a 0.4 mm nozzle and a 0.2 mm layer consumes 0.4 × 0.2 = 0.08 mm³, so a hotend rated at 20 mm³/s tops out near 250 mm/s no matter what the gantry is capable of. Dividing the published flow by that constant is the whole trick, and it is shown with its arithmetic on every printer page rather than folded into a score.
Only 15 of 49 machines here publish a flow rate at all, which is itself the finding. Where a maker publishes none, this site calculates nothing — inferring a flow figure backwards from a speed claim would fabricate the exact number the page exists to check.
6 types, and why a printer only carries one
Every printer holds exactly one of 6 types, so the type counts sum to the catalogue — 49 — rather than double-counting a machine that is both enclosed and CoreXY. The type is the attribute that most changes what you would buy the machine to do: an enclosure, a changer, a plate large enough that size is the reason, or the resin process, which shares almost nothing with FDM but the word “printer”. Motion (CoreXY, bedslinger, gantry) and firmware are recorded separately as facts, not folded into the type.
The 9 resin machines never appear as a related suggestion under an FDM printer, and never share a sort with one. Different consumables, different failure modes, different room.
Read off a specification page, not off a test bench
Specifications are the manufacturers’ own published figures, read off their specification pages and brand stores and cross-checked against named third-party coverage and each maker’s own documentation. Every entry records where its figures were read. Nothing here is a measurement taken by this site: no print has been benchmarked, no hotend has been pushed to its stated flow, and saying otherwise would be an easy lie to tell and a hard one to check. The full method, including which outlets are used and what gets rejected, is set out in how we compare.
Owner reporting, and the label it carries
29 of the 49 printers carry a “What owners report” section, drawn from public owner discussion in 3D-printing communities and kept in its own block with its own heading, so nothing owners say is ever presented as a manufacturer specification. It is where you find the things a spec sheet structurally cannot say: which bed adhesion problems recur, what the changer wastes in purge, which parts owners replace in the first year.
The remaining 20 say plainly that no owner discussion has been collected yet. That sentence is rendered by the component itself rather than left to whoever writes the copy, because a silently empty section looks like an editorial verdict.
Where this catalogue prints nothing
- Flow, for 34 machines. They read “not published” and sort last. An estimate would defeat the point.
- Star ratings, for 47 machines. A rating renders only when it comes from a named, checkable source that permits republication, which 2 currently do. The rest show nothing rather than a number with no provenance.
- Any tally of owner posts. Nobody counted them, so no badge claims a count.
- A composite score. Lists are sorted on one named measurement, printed at the top of the list, so you can decide whether it is the measurement you care about.
Who reads the specification pages
Two people, at home, around other work. No office, no print farm, no staff, and no review samples — no manufacturer has shipped a machine here, because there is nowhere to ship one to. No maker pays for a position in these lists, for a kinder paragraph, or for anything else; no money moves between this site and any brand in it. Nothing on these pages sells you a printer — the catalogue records each manufacturer’s product page as the reference for where a figure was read and stops there — so the order of a list cannot be worth money to us even in principle. If that ever changes it will be written here and on the privacy page before it changes anywhere else.
Passes, not a live feed
The catalogue is re-checked in passes rather than continuously, and the date at the foot of every page is the date of the last one: 2026-09-24. A pass re-reads the specification pages, removes machines a manufacturer has discontinued rather than leaving them looking current, and re-checks prices against each brand’s own store. Prices carry a ~$ because this category discounts hard and often — they are there to rank machines, not to quote back at a retailer. Between passes, nothing on this site silently updates itself, and the date tells you how stale it is allowed to be.
Prices currently span ~$179 to ~$4,299, and 21 of the 25 multi-material machines are listed at a price that does not include the changer they are pictured with.
