When you think about United Parcel Service (if you ever do), you like think about the big brown truck that brings boxes to your house. But UPS does much more than deliver e-commerce purchases to residential addresses. They also have a significant business handling supply chain logistics. That business is potentially threatened by the evolving technology of additive manufacturing. Who needs a logistic purveyor when parts and components can be reduced to a file, sent around the world, and then printed at its point of use?

That concern has led UPS to experiment with 3D printing, investing in a start up and setting up a facility at UPS’s hub in Louisville. They currently have 100 printers and are planing to to expand to 900 (UPS Tests a 3-D Printing Service, Wall Street Journal, Sep 18). Just what are they doing with these printers?

UPS expects more companies will migrate some production to 3-D printing from traditional manufacturing on an aggressive growth curve, according to Rimas Kapeskas, head of UPS’s strategic enterprise fund. And UPS is also talking with customers about taking on a bigger role as a light manufacturer using 3-D printers. …

Late last month, the operation received an order for 40 mounting brackets for paper towel dispensers from a division of Georgia-Pacific LLC that makes dispensers, Dixie cups and cutlery. CloudDDM printed the mounts and UPS shipped them to a Georgia-Pacific engineer by the next morning. The brackets were slated for a month-long “stress test,” said Michael Dunn, senior vice president of innovation development for Georgia-Pacific.

Whirlpool turned to the operation recently when its own 3-D printers were all occupied. The maker of Maytag and KitchenAid products uses the printing method for prototypes of items like trays for refrigerators and venting systems for dryers, as a way to test parts on smaller scale.

The article also reports that UPS has used the service itself to produce parts for its fleet of planes. (more…)

How do you get replacement parts? In a developed country the answer is pretty simple. For some things (e.g., car parts), you may need to go through a dealer or specialized retailer. For others, you may be able to just stop by a general hardware store. But what if you are in a developing nation? Then you might have to get creative.

Markplace had a fun report about craftsmen in Mozambique carving replacement parts (like the gear above) out of ebony (Ebony woodcarvers learn to craft machine parts, Oct 3).

Young Makonde sculptors apprentice for years, sanding and polishing the works of their teachers. They study the ornate canes and traditional busts that are still a bestseller to tourists. But the expert woodcarvers are also finding a market for more “functional” sculptures. Manuel Xavier is a customer here at the woodcarvers’ collective. He repairs gas stoves for a living but has trouble finding spare parts.

MANUEL XAVIER: Here in the north, there is a lack of equipment for gas stoves.

A month ago, Xavier got a call from an unhappy customer. She said that the knobs on her stove had broken off.

XAVIER: I told the woman who owns the stove, “That part isn’t sold here in the North.” Not in stores, or anywhere else. So I decided to have them made out of Pau Preto.

Pau Preto is what the locals call the wood in Portuguese. In English, it’s known as African blackwood, or ebony. …

And versatile. Sculptors have carve parts for espresso makers, sewing machines, and motorcycles. For film projectors, and even computers. Patterson says that storekeepers in Mozambique don’t have the capital to keep spare parts in stock.

The article goes on to report that doing replacement parts is harder than doing creative sculptures. For the latter, there is no formal standard of perfection. Replacement parts, however, must conform to what they replace for them to be useful.

It’s a cute story, but does it have any relevance in the West? We’ll never have hand carved replacement parts, but what if they could printed on demand?
