The differences that matter
- Z height: 385 mm on the Neptune 4 Plus against 260 mm on the Kobra X — decides whether a tall part prints whole or needs splitting.
- XY bed size: 320×320 mm on the Neptune 4 Plus against 260×260 mm on the Kobra X.
- Multicolor with accessory only on the Kobra X (4 colors), absent on the Neptune 4 Plus.
- Price: around €389 for the Kobra X against €350 for the Neptune 4 Plus.
Which one to choose
Choose Kobra X if…
With its dedicated accessory, the Kobra X prints up to 4 colors — useful for prototypes that need parts to stand apart at a glance without moving up to a pricier machine. The rated 600 mm/s helps on repeat runs of simple parts.
Choose Neptune 4 Plus if…
385 mm of Z height against the Kobra X's 260 mm lets taller prints go in one piece instead of being split and glued — vases, tall stands, architectural models. The 320×320 mm bed follows the same logic on X and Y, at a slightly lower price.
