3D Printing in China, a reality check

I received my umpteenth marketing email (i.e. ‘SPAM’) predicting the eminent doom of China’s manufacturing sector thanks to the 3D printing revolution.  Underlying these predictions were assumptions that:

  1. 3D printing will replace traditional manufacturing in the very near future and, more subtly,
  2. That China is completely oblivious to 3D printing.

Personally I do not think that 3D printing is about to supplant traditional manufacturing anytime soon, though I may be proven wrong on this.

However, I am quite certain, that China is very familiar with 3D printing.

Let’s consider some facts for a moment:

  • Revenues from China’s 3D printing industry reached US$163 million last year and pundits have forecast this to grow to US$1.6 billion by 2016, which would make China the largest user of 3D printing technology in the world
  • Beijing has been investing in 3D printing and additive manufacturing research and development since 1992
  • In May 2013, China held its first 3D printing conference – the 2013 World 3D Printing Technology Industry Conference
  • Chinese car makers and aerospace companies already employ 3D printing
  • China’s Dalian University of Technology announced the development of the world’s largest 3D printer
  • China has established network of ten 3D printing innovation centers funded with over US$32.6 million of government investment.
  • China’s AVIC Laser exhibited, what it claimed was the world’s largest 3D printed titanium fighter component
  • China’s Tsinghua University, Xi’an Jiaotong University, Huazhong University of Science and Technology, and South China University of Technology, as well as some higher vocational schools offer course in additive manufacturing
  • A search on www.alibaba.com for 3D printing in China will bring up a large number of rapid prototyping service providers and 3D printed products
  • There are companies selling 3D printed products produced in China using 3D printing (e.g. 3D printed smartphone cases) on the global market
  • There is also a growing body of design talent in China proficient in designing components and other items suitable for 3D printing.

Though China is famed for cheap mass produced goods, the country is looking to 3D printing technology to help its manufacturers produce higher-end goods. Consequently China’s investment focus on 3D printing has been geared more towards technology transfer leading to increased demand and local supply of Rapid Prototyping capability than low-end 3D printers.

Rather than produce small items with 3D printers, the country’s manufacturers have been looking to 3D printing to reduce development times and production waste, particularly in the design, development and manufacture of aircraft.

This focus on large-scale 3D printing technology contrasts with current developments in the West where 3D printing has primarily been driven by (1) product personalization, (2) increased geometric flexibility and functionally and (3) low-volume / high value manufacturing.

Part of this can be explained by relatively high materials costs in China as well as low local demand, both of which have limited the ability of the country’s 3D printer makers to reduce their prices through improved economies of scale as many smaller Chinese companies or ordinary consumers cannot afford 3D printers. This, in turn, has discouraged many of the country’s material producers from developing new products (for 3D printers) because of limited consumption and demand.

One must also remember that it is still possible to get customized (i.e. handmade) goods – or produce customized products in low volumes – more cheaply in China than many other locations.

In summary, it would be dangerous to assume that China (or other countries) do not understand 3D printing technology and its potential benefits simply because China’s market for 3D printing has not developed in the same way as the West.

China clearly understands the potential benefits of 3D printing but because the driving force and focus for 3D printing there is large-scale 3D printing, it would seem that the Makerbots of this world are safe from Chinese competition – at least for now.

    I get this “revelation” regarding China’s downfall in manufacturing resulting from 3D printing.

    Mine come from Motley Fool.

    I love them but I bored of being asked to buy the full report.

    I get that here.

    Good Work.

    Maybe they can make safe food or maybe a glass of milk that will not make babies sick.

      Maybe they can print some baby girls to make up for all the ones they’ve killed through gendercide.

      • Ronald Yu

        Liz raises a good point, the quality of any production process whether through 3D printing or conventional assembly depends the quality of the materials that go into the product and assurances that the materials are not tampered with.

        As for the baby girls, sadly nothing will bring them back. However, I do hope that 3D printing improves quickly to the point where it can replace objects made from animals so that fewer wild animals will be slaughtered.

        I thought I would say I don’t think criticizing human rights issues worldwide is wrong. But the way these were worded sounded to me more ethnocentric than discussing human right issues objectively in our world.

        Maybe we can give back the land to Native Americans, when we made up land contracts for cheap trinckets that Native Americans signed without teaching them we were more or less taking their land. Maybe we can introduce legislation where we give yearly income sentlements to all Native Americans. The Supreme Court did rule the Trail of Tears illegal and yet the government did nothing when Jackson went ahead with it anyway. Maybe we can stop celebrating Christopher Columbus day. This is an accurate reflection of the tone that has been taken when discussing the Chinese human rights issues. If we want to use this tone when discussing this we need to do it in an egalitarian manner.

        Maybe we can print a history correction to make up for all the Native American ones we’ve killed through genocide.
