Voron vs RatRig V-Core 4 — DIY CoreXY Comparison 2025
对比 RatRig Buying Guide
如果您在 2025 年考虑 DIY CoreXY 打印机，两个名字主导了讨论：Voron 和 RatRig。一方面，Voron V2.4 和 Trident——完全开源的机器，由单独采购的组件构建，背后有庞大的社区支持。另一方面，RatRig V-Core 4——一款以套件为先的机器，采用创新的框架设计和官方构建文档，为组装清晰度树立了新标准。两者都能打印出卓越的作品。两者都运行 Klipper。两者都是超越任何消费级打印机的发烧级机器。但它们在构建体验和长期拥有方面截然不同。
简要回答： Build a Voron if you want the largest community, endless mods, full open-source control, and maximum value through China-direct sourcing. Build a RatRig V-Core 4 if you want a larger build volume out of the box, a cleaner assembly experience with better documentation, and a machine that's easier to get printing. Read on for the full breakdown.

定价：Voron vs RatRig V-Core 4
Voron 和 RatRig 的定价模式根本不同，理解这一点对您的决策至关重要。
Voron 定价： QUERY LENGTH LIMIT EXCEEDED. MAX ALLOWED QUERY : 500 CHARS
RatRig V-Core 4 定价： RatRig sells official kits. 价格s range from $899 for the V-Core 4 300mm to $1,299 for the 400mm and $1,799 for the 500mm. The kit includes everything you need in one box — frame, motion system, electronics (Duet or BTT board options), toolhead, wiring, hardware, and printed parts. You don't source anything separately. The premium over a self-sourced Voron reflects the convenience of a single order, official support, and RatRig's higher overhead as a company rather than a community project.
价值分析： A Voron V2.4 350mm at $700-1,200 gives more printer for less money than a RatRig V-Core 4 400mm at $1,299. However, the RatRig 500mm at $1,799 has no direct Voron competitor at that size — the largest Voron is 350mm. If you need a 400mm or 500mm build volume, RatRig is your only option in this comparison.
框架设计与刚性
框架是 RatRig 在 V-Core 4 上采取真正创新方法的地方。Voron 使用标准的 2020 铝型材，通过 M5 螺栓和 T 型螺母固定在角支架上。它经过验证、刚性且广为人知——但这是传统方法。
RatRig 的无支架框架： The V-Core 4 uses custom extrusions with hidden internal brackets. The extrusions have precise machined slots that interlock with each other, eliminating the need for external corner brackets. The result is a cleaner-looking frame with fewer exposed fasteners and potentially better alignment because the joints self-locate. The hidden joint system also improves aesthetics — there are no bracket ears sticking out at the corners.
Voron 的支架系统： Voron's 2020 extrusion + corner bracket approach is simpler to source (2020 extrusions are available everywhere) and easier to modify. If you want to add extrusions for a different panel setup or mount additional components, you can drill and tap standard 2020 extrusion. With RatRig's custom extrusions, you're locked into their profiles — modifications are harder.
在刚性方面，两种设计在正确组装后都表现出色。V-Core 4的隐藏式关节由于互锁设计可能在扭转刚性上略有优势，但在实际加速度下差异微乎其微。一台框架方正、螺栓拧紧的Voron对于任何合理打印速度而言都足够坚固。
运动系统对比
直线导轨： Voron uses MGN9 linear rails on X and Y axes and MGN12 rails on Z. This is a proven combination that balances weight (MGN9 is lighter on the gantry) with rigidity (MGN12 on Z for bed support). RatRig uses MGN12H (heavy) rails on all three axes. The heavier rails add some moving mass but increase rigidity, particularly on larger build volumes where rail flex becomes a concern.
Z 轴运动机构： The V-Core 4 uses a three-motor Z system (fixed gantry, moving bed) similar to the Voron Trident. The Voron V2.4 uses a four-motor flying gantry system where the entire gantry moves up and down. The V-Core 4's approach is simpler to align and tune. The V2.4's flying gantry offers slightly better Z-height consistency for tall prints since the gantry leveling is dynamic.
皮带路径： Both use standard CoreXY belt routing with GT2 belts. The V-Core 4 uses wider 9mm belts on the primary XY drives compared to Voron's standard 6mm, which provides better stretch resistance at high accelerations on larger beds. For 300mm sizes, the difference is negligible. For 500mm builds, the wider belts are a real advantage.
工具头兼容性
Voron Stealthburner： The Voron ecosystem standardizes on the Stealthburner toolhead. It's a well-designed toolhead with excellent 5015 part cooling, integrated LED lighting, and support for multiple hotends (Dragon, Revo Voron, Rapido, etc.) and extruders (Clockwork 2, Galileo 2, Orbiter 2). The Stealthburner ecosystem means you have dozens of community-developed mods available — different fan ducts, probe mounts, cable management solutions.

构建体积选项
这是最明显的区别之一。Voron提供V2.4的250mm、300mm和350mm尺寸，Trident提供180mm（Voron 0）、250mm和300mm尺寸。最大Voron构建体积为350mm立方。
RatRig V-Core 4提供300mm、400mm和500mm尺寸。500mm V-Core 4的构建体积为500 x 500 x 500mm——几乎是Voron 350mm立方体积的三倍。如果您需要打印大型零件（cosplay盔甲、大型外壳、标牌打印），V-Core 4是明确的选择。
关于500mm打印的说明： Printing at 500mm introduces challenges that don't exist at 350mm. Bed temperature uniformity across a 500mm heated bed requires more zones or more powerful heaters. Enclosure temperature management is harder with the larger volume. Part cooling needs to be more aggressive. And the mass of the gantry means you need lower accelerations to avoid ringing. RatRig has designed the V-Core 4 to handle these challenges, but you won't be running the same speeds you could on a 300mm Voron.
固件与软件
Both useKlipper, which is excellent news. You get input shaper, pressure advance, flexible macro support, web-based control via Mainsail or Fluidd, and full remote access. In terms of firmware capability, they're equal.
区别在于默认配置。RatRig为其套件提供预配置的Klipper配置文件，专为V-Core 4的特定硬件定制。您仍需要进行输入整形器和压力提前调校，但基线配置已就绪。Voron的配置更偏向DIY——您从Voron GitHub配置模板开始，自行定制所有内容。Voron社区有出色的配置指南，但前期工作量更大。
组装体验与文档
RatRig在文档方面胜出——且优势明显。 The V-Core 4 comes with a professionally printed, full-color assembly manual with high-quality photos, torque specifications, and step-by-step instructions. It's comparable to what you'd get with an IKEA furniture assembly guide. Every step is documented, every bolt size specified, every alignment check explained. This makes the V-Core 4 significantly easier to build, especially for first-time DIY builders.
Voron的文档： QUERY LENGTH LIMIT EXCEEDED. MAX ALLOWED QUERY : 500 CHARS
组装时间： First-time builders report 8-14小时 for a V-Core 4 versus 12-20 hours for a V2.4. The difference comes from the cleaner frame assembly (no brackets to align), the better documentation, and the fact that the kit is more complete (no self-sourcing delays or wrong-part headaches).
社区与生态系统
Voron社区： QUERY LENGTH LIMIT EXCEEDED. MAX ALLOWED QUERY : 500 CHARS
RatRig社区： Smaller but highly focused and helpful. The RatRig Discord has dedicated channels for each printer model with active troubleshooting support. Because RatRig is a company (not just a community project), there's also official support available. The community is less focused on mods and more on getting the stock machine working well, although the V-Core 4 mod scene is growing.
改装生态系统： Voron has the largest mod ecosystem in 3D printing. From the Nevermore filter to the Galileo extruder to the ERCF multi-material system, hundreds of well-tested mods are available. RatRig's mod ecosystem is smaller but growing, with several popular mods for the V-Core series.
打印质量
两台机器在正确调校后都能产生出色的打印质量。在标准速度（80-150 mm/s）下，您很难区分输出。在更高速度（200-400 mm/s）下，差异缩小到微妙的表面质量变化。
Voron的优势： The lighter MGN9 rails on X/Y keep moving mass lower, which enables higher accelerations. The Stealthburner's 5015 part cooling fan provides more focused cooling for overhangs and bridges. The community-developed Klipper configs (including optimized input shaper profiles) are extremely well refined.
RatRig的优势： The heavier MGN12H rails on all axes reduce micro-vibrations at high speeds on larger builds. The 9mm belts provide more consistent tension over the longer belt path on 400mm and 500mm machines. The bracketless frame may provide slightly better rigidity at scale.
实际上，两者都是顶级打印机。打印质量的限制因素将是您的调校能力、耗材质量和切片机设置——而不是打印机硬件。
开源与长期拥有
Voron是完全开源的。 CAD files, STLs, firmware configs, bill of materials — everything is on GitHub under permissive licenses. You own your printer completely. If RatRig went out of business tomorrow, you could still source replacement parts from standard suppliers. If you want to modify the frame design, the CAD files are available.
RatRig是开源硬件。 The design files and documentation are available, but the custom extrusions and some proprietary parts are RatRig-specific. If you need a replacement extrusion for a V-Core 4, you need to buy it from RatRig or have it custom machined. The electronics options (Duet or BTT) are standard parts, but the wiring harness is custom.
对于长期拥有，Voron的优势在于完全由标准、广泛可用的组件构建。如果您计划保留打印机5-10年，这一点很重要。
