Well, you can make 100+ high-quality plastic parts a week on a $500 SLA printer (if you can fit at least 5 on the bed, vertically), and the price per part for the material could be below $1/part (the goo costs $70 per liter). At least in theory, that's my plan in the next weeks. PCBs are no issue in smaller quantities, although the setup cost for PCB assembly will add to per unit cost if you are doing less than ~500. Here's an example, although perhaps a little big: https://www.youtube.com/watch?v=RDUn3CoVmuc https://www.youtube.com/watch?v=RDUn3CoVmuc Looks quite saleable to me. Maybe sand blasting would improve the finish. The real plus China having Taobao.. like eBay, but with every imaginable component you could need, and five different Chinese clones of it at 20% of the original component cost, all available at wholesale prices, in quantities of 1 or 100,000. The Shenzhen markets are still active, but shrinking.. you can usually find more variety, faster, cheaper, online. You can hand your BOM over to an agent on Taobao, and he'll get the parts together for you and ship them over.. it might cost 1/4 of the price of Digikey.
