We have a 3D printer, and have an evolving list of things to 3D print. Custom design work comprises most of the list now. Originally, I anticipated printing a whole bunch of little plastic bits that are seriously overpriced in retail stores. The bobbins for embroidery thread come to mind — 20 cents a piece (although I’ve subsequently found them at Walmart for 10 cents a piece). They weigh practically nothing. 3D printer filament runs between one and a half cent per gram and four cents per gram (not getting into pricey exotic stuff which doesn’t make sense to use as a base for winding embroidery threads!). I can print six for Walmart’s super cheap price!
And then I thought to check AliExpress – two cents a piece. I can buy 100 for less than the price of 28 at Walmart. Material cost would be a little lower printing with the cheapest filament. But there’s electricity and time to consider as well. I ended up ordering the things shipped from China.
But in the process started wondering if companies use either of these techniques for reducing expenses. 3D printing would be an interesting endeavor – include the company logo, make items the *exact* size needed for an application. But direct ordering from overseas manufacturers has a larger opportunity for expense reduction. Pens for a cent or two each. Ten thousand staples for five bucks. Paper clips, wires and cords, clip boards … there are all manner of random little consumable things companies buy. Start running low on staples, order another ten thousand. So what it takes six weeks to arrive? You’re just refilling a supply closet.
