Inside 3D Printing Seoul 2019 Day Two

After having fun with the superb eating places and nightlife of buzzing Seoul we reconvened for day two of Inside 3D Printing Seoul. After opening remarks by Smartech’s Kirsten Mulherin, Dr. Behrang Poorganji of GE began his keynote. Dr. Poorgangji is the Director of Supplies Expertise at GE Additive. He took us by the essential function that supplies play in steel 3D printing. On this informative presentation, he tooks us by many alternative components of designing and growing supplies for 3D printing. In addition to examples of instances in aerospace and inside GE itself he additionally mentioned 3D printing for medical implants. He gave us an summary of frequent 3D printed supplies in addition to newer titanium alloys. We had been additionally informed of particular alloys for titanium and nickel superalloys in addition to tremendous thrilling growth reminiscent of TiAl (titanium alumide). He took us by lots of the course of parameters in steel 3D printing as effectively. We bought a extremely good overview of lots of the totally different components affecting your 3D printed half. From issues such because the powder supply, powder dimension, powder composition, and powder reuse procedures to the spot dimension, laser powder, laser journey velocity and dwell time to components reminiscent of your hatching technique and recoating parameters. Later he additionally confirmed us how tearing and solidification cracking that’s triggered when the soften pool solidifies. He talked about that understanding this conduct was key to designing and growing good designs for brand new alloys. He additionally took us by how powder characterisation could possibly be aided by pc imaginative and prescient. When then a “physics knowledgeable course of mannequin” was coupled with “multivariate probabilistic optimization” in course of growth was mixed with course of management and evaluation we may have physics primarily based machine studying lead us to new powders and elements.  Dr. Poorganji’s explanations had been actually a watch opener for a lot of to the numerous totally different components that management for a steel construct. The large variety of variables in 3D printing processes will need to have given many pause for thought, particularly those that maybe had been a bit too optimistic about their 3D printing implementation. In addition to giving us an excellent replace on the advances of supplies it supplied us with a really instructional overview of what it takes to fabricate with steel 3D printing.

This was a leitmotiv for the whole day with speaker after speaker returning with data from 3D printing’s frontlines. The day was a refrain of audio system who had been all filling us in on the small print and difficulties of producing utilizing 3D printing. It was actually refreshing to listen to so many spot-on shows that introduced actual realism and data to the ground. Gone had been the hypemasters with their goals on the desktop and overclaim. Right here was actual realism, actual data and other people preaching warning and cautious development. Everybody, to a person, was lifelike and preached realism and shared data that was helpful. Today actually warmed my coronary heart.

I didn’t get to see everybody however Hyundai Motors’ Shinhu Cho continued on this vein by displaying us all the related examples of 3D printing in automotive. From rivals, race automobiles and one-off vehicles he gave us a wonderful overview of the newest implementations in 3D printing for automotive. Clear examples had been mentioned and limitations and progress had been defined effectively to us all.

Subsequent was Manuel Michiels of Materialise. He additionally gave a wonderful presentation that actually imparted data on everybody. In his case, his discuss was enhanced by nice graphics and films displaying us what it could take for us to make certified aerospace elements. He took us by yields, scrap and the precise course of of manufacturing elements that match specs. In his opinion, all of it begins with the precise software. He felt sturdy give attention to course of engineering and productiveness can be necessary as effectively. Analysis demonstrated that half of half failures could also be accounted for by lack of understanding. He confirmed a visibly impressed room how in Magics you could possibly now see FEA simulations that confirmed half stresses. He additionally took us by the function that software program may play in saving cash in manufacturing as effectively.

Julien Cohen works for Eaton of their 3D Printing Middle of Excellence. He additionally gave a extremely instructional presentation that confirmed us how we will go from simply printing elements to having a sturdy manufacturing course of in place. He talked about that going from one half to many and from prototypes to manufacturing was “not a linear development.” He informed us how necessary it’s to “choose the precise elements for additive.” Multidisciplinary groups had been key to avoiding prices and points later within the course of.  An actual eye-opener was the assertion that within the growth of producing processes you had been going to spend “much less time and cash on printing” and extra on optimizing “pre and submit processes” reminiscent of planning and post-processing. He showcased elements that they are going to be 3D printing for Airbus to be used on plane and an modern Ram Air Valve Meeting that was an excellent instance of DfAM and took 22 elements and lowered it to at least one part with a mass discount of 10%. Julien maintains that the Digital Thread is essential for traceability particularly in areas reminiscent of aerospace. Julien additionally informed us that the “course of is the fabric” and that laser energy, scan velocity, spot dimension, layer thickness, uncooked materials in addition to gasoline circulation change your half. He talked about high quality administration as effectively. He talked about that like lots of people in 3D printing he doesn’t like STL and introduced the attention-grabbing level that many engineers don’t understand how edges in an STL may impact fatigue life within the last half for instance. In addition to design he mentioned knowledge administration, manufacturing and course of design in an excellent discuss.

Olivier de Deken of mass customization software program firm Twikit talked about how 3D printing may allow mass customization in automotive. The corporate that developed the BMW Mini mass customization software program, and he went into how this works. He gave us a glance into the Twikbot and how one can set parameters in that device. He informed us how Twikit was additionally specializing in orthotics and prosthetics in addition to life-style merchandise. He spoke about folks “wanting their very own automotive” and that it wasn’t about configuring however “actually about making your individual dashboard, making your individual textures, making your individual automotive fit your needs.” Made to suit seats was one other factor Twikit is happy about. He additionally spoke about individualized elements for car-sharing firms. He talked about how CAD and design itself is totally modified by individualization.

Albert Sutiono of NAMIC then went on to provide a presentation on the mixture of the industrialization of 3D printing and the round financial system. He detailed Singapore’s 200 million funding in 3D printing and 3D printing startups reminiscent of Siege Superior Manufacturing and Bralco. Singapore actually appears to be investing in and producing nationwide startups in many alternative areas and it appears just like the ecosystem could also be growing. Albert seemed into technical and enterprise challenges for 3D printing together with the excessive value of supplies and lead instances. Lack of built-in finish to finish workflow software program and lack of commercially obtainable inexpensive steel printing, in situ course of management and sensible post-processing had been additionally limiting. Requirements can also be one thing that must be addressed. Albert then mentioned and defined the round financial system and the way this can be enabled by 3D printing. All in all, it was an attention-grabbing exploration about how our know-how could essentially change the best way we eat.

Inside 3D Printing Seoul continues till June 28th at KINTEX, South Korea.
