Best Open-Frame 3D Printers: Bambu A1, Prusa MK4S, Kobra, Neptune, Sovol SV08 (2026)

If you mostly print PLA, PETG and TPU, you don't need an enclosure, and open-frame printers give you more build volume for the money and easier access to the nozzle. This page covers bed-slingers (the bed moves front to back), open CoreXY machines and big-format printers. Multi-color support and acceleration separate them more than top speed, which is 500–700 mm/s on nearly every spec sheet.

Buying guide: how to choose the right open-frame 3D printer

Bed-slinger or CoreXY?

Bed-slingers move the bed front to back, which is simple and cheap but needs room behind the printer. Open CoreXY machines like the Sovol SV08 move the head instead and usually list higher acceleration.

Multi-color: decide early

AMS lite, ACE 2 Pro, MMU3 and Flashforge's IFS are each tied to their own printers. Buying the right printer now is cheaper than switching later.

Big volume brings big trade-offs

420 mm+ printers take long to heat, cool and level, and they need a big bench. Print size is limited by what you can dry and spool too.

Open frames and fumes

Open printers don't filter fumes. Print in a ventilated room and stick to PLA, PETG and TPU for long jobs.

How this ranking is calculated

Score = weighted average of normalised specs, out of 10. Full method

Build volumeWidth × depth × height from the spec table, in liters. Anything over 45 L gets full marks; see the large-format guide for the giants. Scale: 6 → 45 L.
25%
Multi-color system offeredYes when the maker sells or builds in a multi-filament system for this printer.
20%
Max accelerationHigher acceleration shortens real print times more than headline top speed. Prusa doesn't publish it, so its models get the category median. Scale: 5000 → 40000 mm/s².
20%
Max nozzle temperature300 °C or more lets an open printer handle PETG-CF, TPU and short ABS runs. Scale: 260 → 320 °C.
15%
Max bed temperatureHotter beds hold PETG and ABS flat on bigger plates. Scale: 80 → 120 °C.

Built-in camera listedYes when a camera ships built in. Optional add-ons count as No.

Frequently asked questions

What's the best first 3D printer?

Look for automatic bed leveling and Z-offset, a 220–260 mm bed and good slicer profiles. Our beginner guide lists picks that publish automatic calibration and a multicolor path.

Can these print ABS?

Several list ABS and ASA, but without an enclosure big parts warp and fumes aren't contained. See our enclosed printer comparison for ABS work.
