Why we recommend it
Most robot parts fit on a standard bed, but a large arm's base, turntable or long links don't — and splitting them adds joints that flex. The Neptune 4 Plus offers a 320 × 320 × 385 mm build volume with auto-levelling, a direct-drive extruder and a 300 °C nozzle, which widens the range of engineering filaments you can print. Choose it if you're designing a bigger arm; for desktop arms a standard-size printer is enough.
