喷墨技术开发人员Xaar已经出版了white paper这表明了它如何超高粘度技术可用于在3D和增材制造应用中“无限制并驱动创造力”。
Through in-house analysis, Xaar has highlighted how the ability of its printheads to deposit fluids with viscosities of around 100 centipoises (cP) at jetting temperature (or 1000cP at ambient temperature), allows them to overcome the traditional drawbacks of inkjet technologies. In fact, thanks to the improved level of precision these printheads are able to achieve, the firm says that Ultra High Viscosity is now taking the inkjet 3D printing or coating of parts to a ‘whole new level.’
“Ultra High Viscosity Technology offers a wide range of new 3D and AM possibilities which are really as wide as the customer can think of,” said Mike Seal, Xaar’s Head of Advanced Applications, Technologies and Fluids. “We’re giving people a new tool to create better products, and with Ultra High Viscosity, transforming traditional and 3D printing by enabling extra material properties that aren’t possible with other inkjet printheads.”
Xaar’s growing AM inkjet offering
Xaar成立于英国剑桥，是高级喷墨打印头的领先制造商，旨在始终如一地精确地精确地进行精确的液体。由于该公司已经迭代开发了技术，因此它逐渐建立了一个投资组合，具有足够的效率和可卸载的优势，包装，标签，陶瓷，玻璃装饰以及越来越多的3D和添加剂制造客户已经开始在各种最终使用中采用它们申请。
该公司最近发行的Xaar Irix’ printhead, for example, is capable of printing 3D fluids and inks, whether they be solvent-based or those needed for industrial use-cases, while its Xaar 1003 printhead is now being shipped withindp polar’s AMpolar i13D打印机，该系统专门为实现零件的批量生产而构建。
通过技术启用了技术ImagineX夏尔平台,荣誉护卫的最新喷咀也显示significant potential within 3D printing, thus to delve deeper into why this might be, and identify further applications for the technology, Seal has teamed up with the firm’s Principal Engineer of Advanced Applications Nick Jackson, to pen a paper they’ve now published online.
Inkjet’s viscosity conundrum
根据Xaar Duo的说法，喷墨打印的速度，分辨率和可靠性使其成为“许多创新者的关键推动者”，但该技术也有其限制。这样的缺点与喷墨兼容流体的“低粘度”有关，因为它们的高流动性使它们很难打印，并且通常会导致它们在实验性生产应用方面被忽略了其他技术。
同时，大多数工业喷墨打印应用程序通常具有高达10-12CP的建议标称喷射粘度，这是受Printhead的架构，流量，温度和流体处理能力等方面影响的参数。XAAR TF技术的开发有助于使喷墨过渡到工业陶瓷市场，在那里装有更多颗粒的流体使基本粘度提高了。
However, the firm says that it’s only with the further development of a new technology and its latest printheads, that the stabilization of increased particle concentrations and densities, as well as the ability to explore higher viscosities in applications such as 3D photopolymer jetting, have now become viable.
应用超高粘度AM
TF技术于2007年推出了“ XAAR 1001”，描述了该公司打印头的开放式子模构结构，该结构旨在降低流动阻力并使高音油墨的喷射。在实践中，TF技术设备能够借助其独特的流体路径来实现这一目标，从而确保流体以非常高的速度流过喷嘴的后部，并连续循环以帮助避免任何障碍物。
Since the introduction of TF Technology, Xaar has continued to build on this approach, developing a new print mode known as ‘High Laydown Technology.’ Compatible with the company’s existing printhead portfolio, the process enables larger drops of material to be deposited at a throughput of up to 165 ml/min, thus it’s increasingly allowing users to address productivity-intensive applications.
继的特遣部队和高搁置电子logies, the firm has also developed Ultra High Viscosity, a capability which allows for the printing of high molecular weight polymers and fluids with high pigment densities and concentrations, which can be used to 3D print parts with functional benefits, such as being more robust, resilient and flexible.
在固定印刷品之前，由于降落的涂抹量减少（称为DOT增益），因此喷射较高的粘度流体也可以对非孔子底物进行改进的边缘定义，并使新型材料被喷墨印刷，包括粘合剂，包括粘合剂，包括粘合剂，包括粘合剂，油漆和光吸师为新的生物医学，汽车，电路，电子和盲文印刷应用开放了技术。
由于其增强的材料兼容性，杰克逊和海豹突击队结束了他们的论文，说Xaar的打印头和超高粘度技术基本上为喷墨开放了新的新应用。二人组补充说，目前，该公司的高级应用团队正在与客户合作探索新的应用程序和技术，而其五步过程可以帮助制造商评估用于新产品开发和高级制造业的流体。
Xaar表示，它正在“继续与许多流体伙伴合作”，以进一步建立其打印头的粘度能力，并且已经确定了其产品在“帮助制造商过渡到喷墨机”和“和为了有效地生产从定制的小部分到质量产生的组件。
“使用喷墨技术，最终原型和产品之间的唯一区别就是您生产的数字，” Seal补充说。“从真正的工业规模启用3D打印到3D印刷零件的质量定量，我们很高兴向客户展示Xaar的UHV技术如何从初始对话到完全商业化。”
