Inside 3D Printing – Seoul

I attended last week’s fourth annual Inside 3D Printing event near Seoul, South Korea. It has been interesting to watch the even grow over the past four years. A total of 10,532 people from 28 countries attended. The event, organized by Rising Media and KINTEX, included three days of exhibition with 80+ companies and a two-day conference with 42 speakers and panelists. Many of the presentations were excellent.

Alex Lalumiere, a director at HP in Singapore, gave one of six keynote presentations. He focused mainly on how HP, as a manufacturing company, is using Multi Jet Fusion (MJF) to produce parts that save time and money. The presentation, focused on the following drill extraction shoe, was one of most interesting and compelling that I’ve heard from HP. It is used to aid in the manufacture of an HP inkjet printhead.

The image at the far left shows aluminum parts that are conventionally manufactured and assembled to produce what you see in the middle. The optimized design, shown at the right, consolidates eight parts into one and was 3D printed by MJF in PA12. This improved design reduced weight from 575 grams (1.27 lbs) to 52 grams (0.11 lb), a savings of 91%. The cost to produce the drill extraction shoe was reduced from $450 to $18, a savings of 96%, according to HP.

The previous example is what’s possible with methods of design for additive manufacturing (DfAM). Wohlers Associates is conducting a three-day, hands-on DfAM course in the Rocky Mountains of Colorado.
