对比 Prusa Buying Guide

QUERY LENGTH LIMIT EXCEEDED. MAX ALLOWED QUERY : 500 CHARS最后更新：2025 年 5 月。

快速结论： Buy a Prusa MK4S if you want a printer that works out of the box with minimal tinkering and don't mind paying a premium for that convenience. Build a Voron if you want the best performance per dollar, fully open-source hardware and software, and a machine you can repair and upgrade for a decade. Read on for the full comparison.

正面交锋对比表

价格明细

The Prusa MK4S kit costs$1,099 directly from Prusa Research. That includes everything you need — printed parts, electronics, motion system, and a 2-year warranty. An assembled MK4S is $1,199. The optional enclosure (the Prusa 外壳) adds $299, bringing a fully-enclosed MK4S to $1,398.

Voron的价格取决于你如何采购零件。通过中国直供（AliExpress、淘宝、认证供应商），当前市场价格为：

• V0.2： $350-650. Includes frame, motion system, electronics, and printed parts. The V0.2 is the most affordable Voron by a wide margin. A fully-sourced LDO V0.2 kit (premium quality) runs ~$650. A self-sourced budget build can hit $350.
• Trident 250mm： $600-1,000. The Trident is the best value in the Voron lineup — fixed gantry CoreXY with triple Z leadscrews for excellent rigidity. A Formbot Trident kit is ~$700; a full LDO kit is ~$1,000.
• V2.4 350mm： $700-1,200. The flagship Voron. A Formbot V2.4 kit (the most popular kit option) is ~$750 for the 350mm version. An LDO V2.4 350mm kit is ~$1,200 with premium components.

中国直购优势： Voron parts sourced directly from Chinese factories cost 40-60% less than buying from US/EU retailers. A V2.4 that would cost $1,800+ from a US reseller can be built for $750-900 with direct sourcing. The trade-off is longer shipping times (10-20 days) and the need to vet suppliers yourself — or use a service like ours that pre-validates suppliers.

速度与打印质量

Prusa MK4S在启用Input Shaper（Prusa称之为“Input Shaper”——自MK4起内置在Prusa固件中）时，最高速度额定为200 mm/s。200 mm/s下的打印质量出色，得益于开箱即用的良好调谐输入整形，重影极少。MK4S还配备了Prusa的Nextruder——一种齿轮减速直驱挤出机，带有用于自动Z偏移的测力传感器——无需手动调整即可实现出色的首层打印。

Voron printers, when properly tuned, can reach300-500 mm/s with comparable print quality. The speed advantage comes from the CoreXY kinematics (lighter toolhead, no moving bed on X/Y) and Klipper's superior input shaper implementation. A V2.4 or Trident at 300 mm/s with good pressure advance and input shaper tuning produces prints that are visually indistinguishable from the Prusa at 200 mm/s — but 50% faster. The V0.2, despite its tiny size, is the speed king: its lightweight gantry can hit 10,000-15,000 mm/s² acceleration with minimal ghosting.

The key difference: Prusa gives you this quality at speedwith zero tuning effort. The MK4S arrives calibrated and ready to print fast. A Voron requires significant calibration time — input shaper, pressure advance, bed mesh, and belt tension tuning — before it reaches its speed potential. But once tuned, the Voron's speed ceiling is considerably higher.

构建体积

Prusa MK4S提供250 x 210 x 220 mm的构建体积——一个宽敞的bedslinger体积，可处理大多数常见打印（RC零件、cosplay道具、功能部件和小到中型外壳）。210mm的Y深度是这里的限制，继承自Prusa i3的血统。

Voron提供三个构建体积层级：

• V0.2： 120 x 120 x 120 mm. Extremely compact. Best for small functional parts, miniatures, gears, connectors, and printing parts for other printers. Not a general-purpose volume.
• Trident： 250 x 250 x 250 mm (standard). Matches the Prusa MK4S on X/Y and exceeds it on Z. Available in 300mm as well. The Trident's cubic volume is more useful than the Prusa's rectangular bed for tall prints.
• V2.4： 250, 300, or 350mm cubed. The 350mm V2.4 is the largest standard Voron and dwarfs the Prusa's build volume. For printing large one-piece items (RC bodies, helmets, enclosures), the V2.4 350mm is in a different class entirely.

组装体验

Prusa MK4S套件是3D打印中记录最完善的组装体验之一。在线手册包含分步说明、照片、扭矩规格和视频教程。初次构建者可以在1-2天内以轻松节奏完成MK4S套件。每个零件都在盒中，按组装步骤标记和分类。固件已预装在控制板上——开机并运行校准向导即可。从开箱到首次打印的总时间：大多数构建者为6-12小时。

Voron组装则完全是另一回事。V0.2需要10-20小时，Trident需要20-40小时，V2.4需要30-50小时。你将需要：

• 切割并组装铝型材框架，确保完全方正
• 安装并校准直线导轨（精细工作——导轨对齐对平稳运动至关重要）
• 自行打印塑料部件（若自备材料）或使用预打印部件
• 连接整个电子系统——主板、步进驱动器、热端、热床、传感器、风扇
• 从头配置Klipper固件：引脚映射、步进设置、热敏电阻校准、限位开关
• 安装并配置Mainsail或Fluidd以使用网页界面
• 校准所有项目：调平、Z轴偏移、输入整形、压力提前、挤出倍率

优势： After building a Voron, you know every screw, wire, and setting on your printer. When something breaks, you can fix it in minutes because you built it. Voron builders universally report that the assembly process, while demanding, is deeply rewarding.

开源理念

Prusa和Voron都声称“开源”，但它们在实践中对这一术语的解释截然不同。

Prusa Research releases the 3D models and source files for their printers under GPL. You can download the STEP files, print replacement parts, and build a Prusa from scratch if you source components yourself. However, the Prusa MK4S firmware is专有 — you cannot modify it, and it only runs on Prusa's proprietary control board (the Buddy board). The slicer (PrusaSlicer) is open source and excellent, but the firmware lock-in means you can't experiment with different motion controllers or add custom features. Prusa has also moved toward a more locked ecosystem with the Prusa Connect cloud service, sparking debate in the community.

Voron Design is fully open source — no exceptions. The CAD files, BOM, firmware (Klipper), assembly guides, and documentation are all on GitHub under permissive licenses. You can:

• 使用任意主板（BTT Octopus、Fysetc Spider、Manta、SKR、Duet——任何支持Klipper的主板）
• 使用任意切片软件（Orca Slicer、SuperSlicer、PrusaSlicer、Cura——使用正确配置时输出质量相同）
• 修改任意组件——更换热端、改变工具头、添加不同探针、重新设计外壳
• 完全离线运行打印机，无需依赖云端
• 根据开源BOM清单自行组装整台打印机，无需从特定公司购买

对我们而言，开源意味着完全自由。 Voron is the only truly open-source high-speed 3D printer platform available today. If you value the ability to control, modify, and repair your printer without asking a company for permission, the choice is clear.

社区与支持

Prusa 拥有最大且最易上手的用户社区。Prusa 论坛活跃，文档详尽，官方支持团队会回复工单和邮件。如果你是 3D 打印新手，Prusa 的支持体系能提供 Voron 无法给予的安全网。

Voron's community lives onDiscord andReddit (r/voroncorexy). It's a more technical, expert-oriented community. Questions that would get a "read the manual" response on an enthusiast forum get detailed, technical answers on the Voron Discord — but you're expected to have done basic research first. The community maintains an extensive knowledge base, user mod database, and volunteer-run support channels. There is no official support — if something breaks, the community helps you diagnose it, but you fix it yourself.

Voron 社区规模较小，但可以说更具创新性。过去 3-4 年间大多数重大 3D 打印创新（基于 Klipper 的输入整形器应用、CAN 总线工具头、工具头 PCB、快速更换探针）均由 Voron 社区推动，随后被商用打印机采用。

可升级性与长期持有

Prusa MK4S 的升级路径有限。你可以添加 Prusa 外壳、升级热端（若为早期型号可升级至标准 MK4S 热端），以及添加 MMU3 多材料单元。但框架和运动系统作为完整产品设计——你无法将 bedslinger 改为 CoreXY 运动结构，无法更换控制板，重大升级需要购买新打印机。Prusa 的升级路径围绕其生态系统设计。

Voron 打印机设计为可无限升级。每个组件均为标准工业零件——你可以将线性导轨更换为更高质量型号、将热端换为不同型号、升级工具头（Stealthburner、Dragon Burner 或定制款）、将主板更换为新一代产品、添加 CAN 总线、安装不同探针，以及更换外壳面板。V2.4 可通过少量打印零件和修订版接线图升级至 V2.4r2 规格。Trident 的固定龙门架设计本身具有可升级性，因为你可以完全访问每个组件。

对于长期持有（5-10 年），Voron 是更明智的投资。你永远不会遇到专有零件停产导致打印机变砖的情况。每个 Voron 组件均可从多个供应商处采购，开源设计意味着新零件总能被制造出来。

最终结论

选择Prusa MK4S，如果：

• 您希望打印机开箱即用，只需最少组装和调试
• 您是3D打印新手，需要官方支持和详尽文档
• 您更看重便利性而非定制化
• 主要打印PLA和PETG（开放式框架）是您的核心需求
• 您想要一台可靠、经过验证且提供2年保修的机器

构建Voron，如果：

• 您追求最佳性价比——V2.4 350mm比封闭式MK4S更便宜
• 您需要高速打印（300-500 mm/s）和大打印体积（300-350mm）
• 您重视完全开源控制，不希望有任何专有锁定
• 您享受组装过程，并想了解打印机的每个部件
• 您打印ABS、ASA、尼龙、PC或其他需要外壳的高温材料
• 您想要一台可维修、升级并持续运行十年的机器

Prusa MK4S 对合适的人来说是一台出色的打印机。它可靠、支持完善，能以最少努力产出卓越打印件。如果你想要的是工具而非项目，它是最佳选择。

Voron 属于建造者、黑客、那些想要超越价格价值的打印机且不畏惧通过组装和调试来获得它的人。它属于那些相信最好的 3D 打印机是自己亲手打造——并对其了如指掌的人。

Both are excellent machines. The real question is:你想成为什么样的打印机拥有者？
