Unless you've been living under a rock, you've undoubtedly come across countless articles discussing the potential for 3D printing to revolutionize product design and manufacturing. As with any new technology, however, existing laws, particularly copyright laws, are not always equipped to keep up with these advancements. This event will include a live demonstration of 3D printing and a discussion of its capabilities from David Struve of Struve Designs, an award-winning design firm. Lisa Moore and Elizabeth Wheeler of The Moore Firm, LLC will then discuss the many copyright issues that this technology raises and sort through whether these issues are likely to result in any real disruption of copyright-reliant industries.

Great post on BoingBoing illustrating disruptive potential to traditional supply chain by 3d printing technology. It is also a small case study how physical objects can behave as digital objects.

Basically, someone on internet said:

I need this plastic replacement part, but it is incredibly expensive!

Few hours later, complete stranger sent him .stl file to 3d print that part.

Truly revolutionary!

On separate note, there are two additional things to think about here:

1. if you run a company with business model based on sale of overpriced small plastic parts, maybe it is time to think it over
2. if you want to be a (rich) lawyer, you should start researching 3d printing

From the source article:

Back in April, a redditor complained that a simple plastic cable-comb (used to bundle cables) was too expensive at $45. Later that day, WillySF modelled a printable cable comb and linked to the shape files (1, 2). It's a bit of a futuristic moment, no?
Saw the cable comb on Amazon with prime shipping

Here is another example of DIY 3d printable replacement part, this time for popular personal activity / fitness tracker Jawbone Up.
The cap can be lost or broken and someone designed replacement cap (with their logo on it). Retail price of the original part is around 10 $ + shipping, so printing it can save huge percent of that cost.
It shows how home 3d printing can change economics of replacement parts and raises some questions about IP rights. Since I'm sure that this trend of DIY replacement parts will continue  I wonder what will be the response from the corporate manufacturers and design IP rights owners.
