Great article. Certainly, inventory strategies for companies will adapt and 3DP will become the new normal for legacy parts once consumers become comfortable with the technology's capabilities and governing bodies certify 3DP as an acceptable process for these parts. There's an awful lot of money currently tied up in safety stock, and a lot of revenue opportunity lost whenever a production line has to be stopped to make an obsolete part for a customer. Tons of potential customer goodwill benefit from being able to deliver out of warranty parts in a timely fashion too. To curious aardvark's comment, what will be interesting to see is where the liability lines are drawn as production increasingly shifts to 3DP. I could see a good number of low risk parts being produced by consumers at home, but for most industrial functions - aerospace, auto, life sciences, etc. - OEMs are likely to demand a degree of oversight whether or not a governing body requires it (e.g., FAA, FDA). Will any OEMs take the plunge and let consumers print their designs "at their own risk?" I could see it happening, but it will be a while if so.
