The Ender 3 V3 Plus is the large-format version of the V3, adding 80mm in each XY axis for $90 more. The CoreXZ motion system is worth understanding before buying: unlike CoreXY (where both X and Y motors move the print head), CoreXZ moves the print head in X while the Z gantry also participates in motion. It produces better results than a pure bedslinger, especially at speed, but at 600mm/s on tall narrow parts, the bed movement in Y can still cause wobble that a CoreXY avoids.
For 300×300mm PLA and PETG printing at high speed, this is one of the best-value machines available. The limitations are: no enclosure (no ABS/ASA for large parts), and the bed inertia issue on tall narrow prints at maximum speed.
What It Does Well
300×300mm at $289 is compelling. The next step up in enclosed 300mm territory (Creality K1 Max) costs $599 and adds an enclosure but drops Z height to 300mm. The V3 Plus provides more total build volume at half the price, for users who don’t need the enclosure.
Klipper-based firmware with input shaping handles 600mm/s without the ringing artifacts that made older bedslingers unusable above 150mm/s. Direct drive handles the material range expected at this price.
110°C max bed temperature is adequate for ABS first layer adhesion, though the open frame makes consistent ABS printing on large parts difficult regardless.
Where It Falls Short
CoreXZ has a fundamental limitation: at very high Y-axis speeds, the bed movement causes inertia issues on tall parts. For wide flat prints (large plates, bases, flat models), this doesn’t manifest. For tall narrow prints above 150mm printed at 400mm/s+, some ringing or layer shifting can occur from bed dynamics. Reduce speed for tall narrow models.
300×300mm bed requires careful attention to leveling consistency — the larger the bed, the more temperature variation affects flatness. The 121-point mesh leveling compensates well, but a cold-to-hot thermal cycle on a 300mm plate introduces more bow than a 220mm plate.
No enclosure: ABS parts wider than 100mm will warp. The hardware supports it (300°C nozzle, 110°C bed) but the open frame negates it for large prints.
Materials
PLA and PLA+: 215–220°C, 60°C bed. Print at 300–400mm/s for normal quality, 150mm/s for perimeters on demanding prints. The speed range gives flexibility.
PETG: 240–245°C, 70–80°C bed, fan 40%. Reduce outer wall speed to 80–100mm/s. PETG bonds aggressively to PEI at high bed temps — 70°C is usually sufficient to prevent over-adhesion.
TPU (95A): 220°C, 25–30mm/s, retraction 0.5mm. Direct drive makes this workable. Large flat flexible prints are well-suited to the 300mm bed.
ABS: Possible for small parts under 80mm. Larger than that without an enclosure, expect warping on the corners from temperature differential. Use a brim and print at a slow 60°C/100°C bed setup.
vs. the Competition
Creality Ender 3 V3 ($199): Same CoreXZ, 220×220×250mm, $90 less. If you regularly print near 220mm limits or want the extra space, the Plus is worth $90 more.
Elegoo Neptune 4 Plus ($299): Similar format (320×320mm), Klipper, slightly larger at a similar price. Closely competitive — Neptune 4 Plus edges it on build area.
Creality K1 Max ($599): 300×300mm CoreXY enclosed. The K1 Max adds an enclosure and CoreXY motion for $310 more. If ABS/ASA printing on large parts is a real need, the enclosure justifies the cost.
