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焊接性优势，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雷电竞充值申请。
The company’s recently-released ‘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 printer, a system that’s specifically built to enable the mass-production of parts.
通过技术启用了技术ImagineXplatform, Xaar’s latest printheads have also shown 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。
Most industrial inkjet printing applications, meanwhile, have typically had a recommended nominal jetting viscosity of up to 10-12cP, a parameter affected by aspects such as a printhead’s architecture, flow rate, temperature and fluid handling capabilities. The development of Xaar’s TF Technology helped enable the transition of inkjet into the industrial ceramics market, where fluids loaded with more particles have pushed the base viscosity higher.
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.
Applying Ultra High Viscosity AM
Launched in 2007 with the ‘Xaar 1001,’ TF Technology describes the open sub-manifold structure of the firm’s printheads, which are designed to reduce flow resistance and enable the jetting of highly-pigmented inks. In practise, TF Technology devices are able to achieve this thanks to their unique fluid paths, which ensure that fluids flow past the back of the nozzle at a very high rate, and continuously recirculate to help avoid any blockages.
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.
Hot on the heels of its TF and High Laydown technologies, 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。
Thanks to their enhanced material compatibility, Jackson and Seal concluded their paper by saying that Xaar’s printheads and Ultra High Viscosity Technology essentially open new applications for inkjet. The duo add that, at present, the firm’s Advanced Applications Team is working with customers to explore new applications and technologies, while their five-step process helps manufacturers evaluate fluids for use in new product development and advanced manufacturing.
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。
“With inkjet technology, the only difference between your final prototype and your product, is just the number you produce,” added Seal. “From enabling 3D printing on a truly industrial scale, to the mass-customization of 3D printed parts, we are excited to show customers how Xaar’s UHV Technology can take them from an initial conversation through to full commercialization.”
