HP金属3D打印机已由生命值在2022年国际制造技术展览会（IMT）。3D印刷行业本周在芝加哥参加该节目。
生命值’s efforts to expand into metal 3D printing began to take shape in 2017 when plans for a high-volume jetting system were unveiled at its Security Analyst Meeting. As identified by 3D Printing Industry in 2017,惠普的金属3D打印机was expected to use Metal Injection Molding powder. HP would confirm this a year later.
惠普（HP）备受期待的金属喷气技术于2018年宣布，旨在与金属注塑成型（MIM）材料一起使用，而不是激光烧结金属添加剂制造系统中使用的球形粉末。根据该公司3D打印金属业务的全球负责人拉蒙·牧师（Ramon Pastor），这是“大事”，因为它使用户可以“将成本降低成本”下降20％至33％。
The Metal Jet S100 will launch with stainless steel 316L and 17-4PH compatibility. Pastor says that its efficiency improves its ergonomics in a way that allows it “to drive scale,” and HP “sees huge opportunities” for the system to address clients in the industrial, medical, consumer, and automotive industries.
惠普的金属射流3D打印旅程
自2014年揭幕其MJF概念以来，HP已在基于聚合物的机器和材料中建立了3D打印产品。在这段时间，生命值systems have 3D printed over 130 million parts, and MJF continues to address the needs of firms across sectors, with the likes of丰田现在3D打印汽车备件via the technology and奥卡多3D printing fulfillment bots.
Desktop Metal,Markforged, and数字金属have all launched their MIM powder-based machines. With a longer history and broader customer base, metal injection molding powders are currently cheaper than the metal powders required for additive manufacturing processes such as Direct Metal Laser Sintering (DMLS) or Electron Beam Melting (EBM). However, it has often been pointed out that material cost is not the only challenge when it comes to scaling metal 3D printing; repeatability/reliability, cycle time, post-processing, and capital investment are just some of the other considerations. Potential customers will no doubt be happy to pay less for materials.
Speaking ahead of the Metal Jet S100’s launch, Pastor described the platform as the “first introduced that is prepared to economically bring parts at scale.” HP’s metal 3D printing boss added that the system has been built with a “focus on total cost of ownership,” in a way that ensures “the variable cost of a part is the point at which users can scale production.”
Launching the Metal Jet S100
So, how does HP’s first Metal Jet 3D printer work? As the company has now revealed, the Metal Jet S100 comes fitted with a 430 x 309 x 200 mm powder bed onto which droplets of material are jetted by six HP Thermal Inkjet printheads attached to two print bars, equipped with a total of 63,360 nozzles.
使用这些打印头，该系统能够精确地将每层的液体粘合剂液液滴液液滴至最多6.3亿纳米液滴，以形成零件，分辨率为每英寸1,200点（DPI）。
In practice, the Metal Jet S100 is designed to be modular, so more than one can be installed to create a continuous production line as part of a four-step process. After print preparation and manufacturing via HP’s powder management station, users can then debind parts using its curing station before removing any excess powder with any third-party system of their choosing.
为了帮助实现这一自动化过程的潜力，惠普已开始与合作伙伴合作GKN,Parmatech,眼镜蛇高尔夫, theLegor Group, and Volkswagen. User-wise, the technology has also been adopted by initial clients like Domin Digital Motion, Lumenium, andSchneider Electric, the latter of which has already harnessed it to optimize the production of industrial metal air filters.
牧师解释说：“该金属空气过滤器用于断路器中的电弧线时，您需要不影响其余的安装。”“通常，这些过滤器是通过传统措施制成的，而且非常非常昂贵。我们已经能够减少生产时间的时间，并减轻体重的改善，因为它们现在更加紧凑。”
Speculators have argued that the massive gap between announcement in 2017, and launch in 2022 of the HP Metal Jet was a deliberate tactic. The announcement giving pause to potential customers who might defer their capital investments knowing an HP metal 3D printer was on the horizon. Will the success of HP’s efforts with Multi Jet Fusion translate into similar results in the metal 3D printing space?
Furthermore, it is noteworthy that the number of additive manufacturing companies producing MIM-based 3D printing systems is relatively small – with an element of cross-pollination.
Technical specifications and pricing
