📌 Metal Base & Scrap Labs Usher in an Ultra-Low-Cost Sub-$10,000 Metal LPBF Evolution
The landscape of metal additive manufacturing is undergoing a seismic shift. For years, the high cost of industrial Laser Powder Bed Fusion (LPBF) systems placed them firmly out of reach for most workshops, let alone enthusiasts. That barrier is now crumbling, thanks to pioneering efforts from companies like Metal Base and Scrap Labs, who are ushering in a new era of ultra-low-cost metal 3D printing.
金属增材制造的格局正在经历一场颠覆性变革。多年来，工业级激光粉末床熔融（LPBF）系统的高昂成本使其远超出大多数工坊的承受范围，更不用说爱好者了。如今，这一壁垒正在瓦解，这要归功于Metal Base和Scrap Labs等公司的开创性努力，它们正引领超低成本金属3D打印的新时代。
The revolution began in earnest last month with Dutch firm Metal Base. Founded by engineer Tom Bakker, the company engineered a value-optimized LPBF system with a direct path to the powder bed and superior airflow, debuting at an astonishing price point under $10,000. Skepticism was widespread, but Bakker had a powerful rebuttal: six beta systems were already operational at customer sites, including private homes.
这场革命于上个月随着荷兰公司Metal Base的崛起而正式拉开序幕。该公司由工程师Tom Bakker创立，设计了一款价值优化的LPBF系统，具备直达粉末床的路径和卓越的气流设计，首发价格惊人地低于1万美元。尽管质疑声四起，但Bakker提出了有力反驳：已有六台测试系统在客户现场（包括私人住宅）投入运行。
This proven track record fueled a highly successful Kickstarter campaign. Surpassing its initial €51,000 goal, Metal Base raised over €93,870. This funding will enable the production of 23 additional units, building on the existing six. What began as a fanciful dream is now a funded project with real machines producing real parts, signaling a major step toward accessible metal AM.
这一实际成果推动了其Kickstarter众筹活动大获成功。Metal Base不仅突破了最初5.1万欧元的目标，更筹集了超过9.387万欧元。这笔资金将用于在现有六台设备基础上，再生产23台设备。这个曾经看似天方夜谭的梦想，如今已成为获得资金支持、能用真实机器生产真实零件的项目，标志着金属增材制造迈向普及化的重要一步。
Not to be outdone, US-based Scrap Labs is joining the fray. The Boulder, Colorado team plans to debut its “Scrap 1” 3D printer at the upcoming Rocky Mountain RepRap Festival (RMRRF). Their offering includes a kit for $14,990 and a fully assembled machine at $17,990, with shipments targeted for 2027.
不甘示弱的美国公司Scrap Labs也加入了竞争。这支来自科罗拉多州博尔德的团队计划在即将举行的落基山脉RepRap节（RMRRF）上首次展示其”Scrap 1″ 3D打印机。他们的产品包括售价14,990美元的套件和17,990美元的整机，目标发货时间为2027年。
The reported specifications are compelling for a machine in this class:
- Build Volume: 100 x 100 x 100 mm
- Laser: 200W at 915 nm
- Layer Height: 20-100 microns
- Software: Built on Klipper, compatible with PrusaSlicer and OrcaSlicer, with a custom ScrapSlicer in development.
据报道，该机器的规格参数在同级别中颇具竞争力：
- 构建体积： 100 x 100 x 100 毫米
- 激光器： 200W，波长915 nm
- 层高： 20-100 微米
- 软件： 基于Klipper，兼容PrusaSlicer和OrcaSlicer，定制版ScrapSlicer正在开发中。
The company’s ambitious material portfolio includes stainless steel, tool steel, copper, nickel alloys, and cobalt-chrome (CoCr). However, this ambitious material list, particularly for a machine intended for less-controlled environments, raises significant health and safety concerns that cannot be ignored.
该公司雄心勃勃的材料组合包括不锈钢、工具钢、铜、镍合金以及钴铬合金（CoCr）。然而，对于一台旨在用于控制较少环境的机器而言，这份雄心勃勃的材料清单，尤其是包含某些材料，引发了不容忽视的重大健康与安全隐患。
The prospect of printing advanced alloys like cobalt-chrome on a desktop machine is fraught with danger and demands extreme caution. CoCr powder is a known skin irritant, sensitizer, and a presumed human carcinogen (classified as 1B). Studies have shown that handling these powders leads to dermal exposure and widespread surface contamination. In case of fire, the oxide fumes are carcinogenic.
在桌面设备上打印钴铬合金等先进合金的前景充满危险，需要极度谨慎。钴铬合金粉末是已知的皮肤刺激物、致敏物，并被推定为人类致癌物（分类为1B）。研究表明，处理这些粉末会导致皮肤接触和广泛的表面污染。一旦发生火灾，其氧化物烟雾也具有致癌性。
While the democratization of technology is exciting, it must be paired with rigorous responsibility. The inclusion of such hazardous materials in a platform targeting a broad audience is a serious concern. For the vast majority of users exploring premium STL files for functional prototypes or custom tools, safer alternatives like various grades of stainless steel are not only sufficient but highly recommended.
虽然技术的民主化令人兴奋，但必须与严格的责任感相结合。在面向广大用户的平台上包含此类危险材料是一个严重问题。对于绝大多数探索高级STL文件以制作功能原型或定制工具的用户而言，更安全的替代品（如各种牌号的不锈钢）不仅足够，而且强烈推荐。
Despite the safety debates, the core trend is undeniable: metal 3D printing is becoming radically more accessible. This opens up incredible possibilities for rapid prototyping of metal components, custom tooling, small-batch production, and advanced R&D outside traditional factory settings. The success of these projects proves there is a hungry market for capable, affordable metal AM systems.
尽管存在安全争议，但核心趋势不可否认：金属3D打印正变得前所未有的触手可及。这为金属部件的快速原型制作、定制工具、小批量生产以及传统工厂环境之外的高级研发开启了令人难以置信的可能性。这些项目的成功证明，市场对功能强大、价格合理的金属增材制造系统有着迫切需求。
As this technology evolves, a focus on safety, education, and responsible material handling will be paramount. The dream of a desktop metal forge is inching closer to reality, empowering creators to bring their most durable and complex 3D printing models to life in metal.
随着这项技术的发展，关注安全、教育和负责任的材料处理将至关重要。桌面金属打
