Outline :
Three-dimensional (3D) printing is an additive printing process used to make 3D solid objects from a digital model.
Until recently 3D printing has been rapidly gaining market popularity and it is on its way to becoming a multi-billion dollar business. 3D printing offers the ability to produce—both rapidly and inexpensively—short runs or
one-of-a-kind parts. In addition, 3D printing will revolutionize part manufacturing and the part distribution
supply chain by offering local, on-demand production. Over the past decades, various kinds of additive
manufacturing processes have been developed; stereo lithography, fused deposition modeling, and selective
laser sintering (SLS) to name a few. Though strengths and weaknesses are inherent to each of these technologies,
none of them meets the set of minimum satisfactory requirements of the ideal product; such as low product cost,
high production rates, good mechanical performance, good stability, and fine surface finish. To meet these
challenges, HP thermal inkjet-assisted Multi Jet Fusion (MJF) technology has been proposed to deliver
3D thermoplastic parts with superior mechanical properties to current SLS systems at breakthrough production r
ates (5-10x faster) at a fraction (~30%) of the hardware cost. These breakthroughs can power the widespread
adoption of 3D design and hardware innovation, creating the opportunity for a digital transformation of
manufacturing as widespread and profound as the way HP’s Thermal Inkjet solutions changed traditional printing.
HP Multi Jet Fusion is a new technology built on decades of investment in HP’s assets in inkjet printing, inks
and jettable agents, precision low-cost mechanics, and material science. HP Multi Jet Fusion technology
offers speed advantages as well as control over part and material properties beyond those found in other
3D printing processes.
About the Speaker :
Hua Tan is currently a research engineer of Engineering Modeling and Analysis Group of Hewlett-Packard (HP)
Company in Oregon USA. He obtained Ph.D. in Mechanical Engineering from the University of Wisconsin-
Milwaukee in 2010. Since joining the modeling team of HP in June of 2010, He has been providing modeling
services and consultancy to various development programs at HP. Dr. Tan gets involved with a large variety
of research projects in microfluidics and additive manufacturing (3D printing), ranging from fundamental study
to product development. He develops HP proprietary modeling tools that can be accessed by engineers across
the entire organization on a 24 hour-7day basis. Currently, he is leading the development and deployment of HP’
s next-generation microfluidic modeling tool and modeling effort to seek fundamental understanding of the key
issues of HP’s disruptive 3D printing technology-Multi Jet Fusion.
