The Ender 5 S1 uses a cube-frame design where the bed only moves on the Z axis — up and down — while the print head handles X and Y motion. The result is that the print itself never experiences lateral inertia from a moving bed. For tall, narrow, and heavy prints, this is a genuine mechanical advantage over bedslingers where the bed moves in Y. The trade-off: 250mm/s max speed and a 2022-era price that doesn’t compete well against faster modern alternatives.
What It Does Well
The Z-only bed motion is the defining feature. A 200mm tall, narrow bracket printed on a bedslinger risks wobble or layer shifting from bed Y-axis inertia at high speeds. The Ender 5 S1’s fixed-bed-in-XY design eliminates this failure mode entirely. Tall figurines, narrow structural columns, and any print with a high aspect ratio are more reliable here than on a comparable bedslinger.
Sprite direct drive extruder is all-metal at 300°C — same as the Ender 3 S1 Pro. TPU, nylon, and high-temp filaments are within hardware capability.
The cube frame is rigid. At 250mm/s, ringing artifacts are less pronounced than on less rigid frames, even without input shaping. The structure absorbs vibration better than gantry designs.
Where It Falls Short
250mm/s in 2025 is slow. The Ender 3 V3 runs at 600mm/s on a CoreXZ design and costs less. The Ender 5 S1’s mechanical advantage in tall prints doesn’t compensate for the speed gap on most workloads.
220×220mm build area is standard but the cube frame design uses more floor space than an equivalent bedslinger. The footprint is larger than the build volume would suggest.
No enclosure means ABS and ASA are limited to small prints. 110°C bed helps with adhesion, but the open sides create temperature gradients that cause warping on parts larger than roughly 80mm.
The firmware is Marlin-based without Klipper’s input shaping or pressure advance. At 250mm/s, this is less critical, but there’s no firmware upgrade path to modern motion planning features.
Materials
PLA and PLA+: 215–220°C, 60°C bed. Run at 150–200mm/s for quality prints. The stable frame produces clean results at these speeds.
PETG: 240–245°C, 70–80°C bed, fan 30–40%. PETG’s print speed requirements (80–120mm/s for quality) align well with this machine’s comfortable speed range.
TPU (95A): 220°C, 20–25mm/s, retraction 0.5mm. The Z-only bed movement is genuinely helpful for TPU — no Y-axis bed movement means flexible prints don’t get knocked over or stretched by bed inertia.
ABS: 240–250°C, 100–110°C bed, zero fan. Small parts work. Larger parts need an enclosure. The cube frame design makes adding an enclosure straightforward (flat sides).
Nylon: 250–270°C, 80–90°C bed. Dry thoroughly. The all-metal hotend enables it. An enclosure significantly improves success rate on nylon.
vs. the Competition
Creality Ender 3 V3 ($199): CoreXZ, 600mm/s, half the price, similar material range. Worse for tall narrow prints due to bed Y-axis movement, better for everything else. A better all-around choice for most users.
Bambu A1 Mini ($299): Direct drive, 500mm/s, 180mm cube, AMS Lite compatible. Bambu’s ecosystem is more polished. Choose Ender 5 S1 for the larger volume and cube-frame stability advantage.
Artillery Sidewinder X3 Plus ($399): 300×400mm, Klipper, 500mm/s, same price. Much more build volume and speed. The Ender 5 S1 only wins for the specific use case of tall narrow prints where Z-only bed movement matters.
