On the first day of Formnext 2018, Boston metal 3D printer provider桌面金属已经升级了其工业规模生产系统。
Scheduled for installation with its first customer at the start of 2019, the Production System has undergone a number of major advancements promising to deliver “the lowest cost per part with the highest capacity of any metal 3D printing system available.”
According to台式金属首席执行官兼联合创始人Ric Fulop:
“We are excited to provide the international engineering and design community with deeper insights into the power of the Production System with updated innovations and an extensive display of metal parts to be publicly shown for the first time this week.”
In addition to new parts from the system, the company also boasts that these updates make the Production System “the fastest metal printer in the world.”
单次喷射技术
The Production System, in contrast to the company’s compact FFF-based工作室系统, is a large scale machine that works usingSingle Pass Jetting（SPJ）技术 - 一种基于喷墨和粉末的金属3D打印方法。
据报道，在最近的升级中，生产系统的构建信封已增加225％，达到750mm x 330mm x 250mm的测量seen at IMTS 2018。此外，将初始打印速度提高50％，生产系统现在的平均速率为12,000 cm3/小时，相当于每小时60千克的金属。
For complex parts, consolidation and mass serialization
为了展示生产系统的功能，桌面金属已经准备了三个基石案例研究，每个案例研究都解决了工业3D打印的关键挑战。
For complex part production, Desktop Metal shows the Milwaukee® Tool spauger bit. An intricate precision tool head, the spauger bit has been created on the Production System in a 4 step process, compared to a total of 14 steps needed in the traditional manufacturing process.
Further, part consolidation is demonstrated at high volume by a batch of print-in-place hinges, akin to the kind you use to build a metal watch strap. Measuring just 12 x 5 x 6 mm each, the Production System can print over 20,000 of these hinges in a single four-hour build.
And, for mass serialization the company demonstrated a set of gears each 3D printed with and individual ID number. Custom markings of this nature can be automatically generated when 3D printing on the Production System, cutting out the need to process each part independently.
生产系统availability
生产系统的第一个客户已被桌面金属确认为该公司早期先驱者中的“财富500强公司”。在整个2019年，该公司预计，客户将进一步安装生产系统“在主要的汽车，重型和领先的金属零件制造商处”，并计划于2020年广泛使用。
在闭幕评论中，福罗普说：“随着我们继续扩展我们的全球客户和合作伙伴列表，正在求助于生产系统可用的改变游戏规则的技术，并将在未来几个月内开始推出安装。金属正在寻求将行业进一步转移到原型中，包括全尺寸金属制造。”
升级生产系统打印的第一个示例用例3D在Formnext 2018 - 3.0厅C10上展出。
