Reactions

Why people turn down the opportunity with 3D printing?

During the past year I have discussed with several industries and disciplines about the possibility to apply 3D printing technology in their activities in some form or another. I have been curious about the new opportunities and visions people create when they are faced with new technology, and also about the fears and sceptisism.

The discussions have taken place with people from manufacturing, construction, education, arts, making of musical instruments, bike builders, museums, designers, researchers, handcrafts, subcontracting, OEM, and many more.

In most cases the discussions and first reactions take similar paths: ”Our business is so conservative and traditional that I don’t see 3D printing coming into our activities in any way. The technology is far too expensive for us. And I believe, 3D printing is not mature enough or reliable for our business.” And they are right. This is of course the case when you come from a tradition and have established well-working and optimized practises.

Does this sound familiar? The experiences and encounters are more or less similar among all 3D printing evangelists and practitioners when they discuss with nonbelievers.

Simultaneously exploring the same industries and disciplines yields numerous examples and use cases how people already apply 3D printing in that specific application, industry, or discipline, and generate revenues with the new technology. The same observation emerges by looking at the industry forerunners and industry reports. 3D printing is applied in new areas and applications every day.

 

”No additive process (3D printing) can duplicate strength of the base material that could have been cast, moulded or machined from bar, let alone compete with the complex structures of composites” (Bike expert, 2013)

”First metal 3D printed bicycle frame”, ”Custom 3D printed titanium mountain bikes”, ”Robot Bike Company teams with AM experts on custom 3D printed bike frame”, ”Custom 3D Printed Carbon Fiber Bike Frame” (News titles on 3D printing and bikes, 2016)

What can we learn?

  • Forerunners do change the industry. Whatever business you think of, there is already somebody applying or exploring 3D printing. The number of these forerunners is overwhelming. And they seem to turn exploration and demonstrations into new businesses very quickly.
  • We are dealing with the phenomena of fast and slow thinking (Kahnemann). This is something deeply human which we can’t avoid. Fast thinking is automatic reaction that focuses on maintaining status quo and safety. It is often irrational and based on the incomplete, even conflicting, information that we have in the active memory. To my mind, forerunners are masters in slow thinking – combining and creating new information with deeper thought, and passing the phase of fast thinking without damage.
  • There are knowledge gaps. It is obvious that most of us don’t know enough about 3D printing and current status. And why should we? The technology is developing fast and it is really worksome to get proper information beyond the hype texts, successful demonstrations (forgetting the failed ones) and videos.
  • Consistency. It is interesting that the protective attitude against applying 3D printing is so similar across people and professions. Why guitar builders think that 3D printing will never come to their business? Why metal manufacturing company uses exactly the same words to turn down the opportunity?

The industrial renaissance and digitalisation, where 3D printing is one essential element, is a great task for all educators, knowledge generators and advocates. We all will be challenged by the new opportunities, the inefficiency of old practices and by the new business models and economy that have started to emerge.

We must think slow.

3D Printing and bikes

How 3D printing contributes to building and maintaining bikes?

This question was explored in Velo Vision magazine (Issue 45, July 2013), written by Pekka Ketola and Peter Eland. Download the full article from here.

Examples

Bike builders have already been active in exploring the possibilities. For example:

  • thingiverse.com, a catalogue for sharing 3D printing files, provides almost 300 bike-related items. The selection is growing every day, and covers everything from light mounts to preliminary designs for printable hub gears.
  • A clip-on drive pulley for an electric bike has been created. See: youtu.be/L4INtIgq1MQ
  • EADS, a Bristol based company, has created titanium bike parts including dropouts, working with bike company Charge. See: youtu.be/tkwd2YXNy9I
  • Parts to personalise bikes, specifically super-intricate lugs for framebuilding, have been printed from stainless steel. See: youtu.be/HwJwcnV-wso
  • TREK Bicycles has created functional bike parts, including suspension components, bar ends, frame parts, helmet models and more. See: http://youtu.be/7w2wB6hW-OI
  • Fairings for velomobiles could be printed, although I’m not sure it has yet been done, probably for cost and material reasons. Similar structures have, though, been printed for cars and motorbikes. Search for the Urbee 3D printed car, for example.
  • A complete bike has been printed too, although as a technology demonstrator more than as a practical product in its own right. See: youtu.be/hmxjLpu2BvY
  • Motorbikers have also been experimenting with 3D printing, and share many of the possibilities outlined in this article.

My predictions

In a few years, the bike industry and the culture of building and maintaining bikes will change. This future is already here in the form of early adopters, trials and experiments. My predictions are:

  1. That any bike builder will be able to design and produce new bikes, parts and special accessories in small volumes. Experimenting and prototyping will be fast and cheap. We will see very exciting bike designs and structures.
  2. Bike repair and maintenance services will change radically, as all parts will be available almost instantly, if not via the company’s own printer, via a printers in the same city. Fixing special and antique bikes will be easy and economical.
  3. Local bike manufacturing will boom, with the help of local printing houses. Business models will be revolutionised. Cycling communities will be active in designing and sharing bike parts worldwide.
