Recently a good friend shared a copy of "Wired" magazine with me because it has an article about a company producing 3-D printers (October 2012, page 136, the company is MakerBot.) She has recognized the potential this technology has for home-made doll furniture!
After reading the article I have a slight idea of how these things work (and a reminder of how far out of touch I am with the "modern" world!) Here is a Wikipedia article that helps http://en.wikipedia.org/wiki/3D_printing (Make sure to scroll down to the "domestic and hobby uses" area.) The article in "Wired" predicts that such "printers" will be standard home computer peripherals in the very near future. And both the article and the Wiki entry point out one of the plus points in this type of production of objects: "Traditional techniques like injection molding can be less expensive for manufacturing polymer products in high quantities, but additive fabrication can be faster, more flexible and less expensive when producing relatively small quantities of parts" (Wikipedia) - Etsy-type stuff!!!!!
So, let me know when you get yours and start producing doll furniture! But meanwhile I guess I'll stick to my current method - 2-D paper printouts of scans of ME magnetic dollhouse furniture, with added sides and tops, folded and glued into (fragile) 3-D objects. (And to those of you tempted to use cinnamon hard candies for the bright red knobs on the drawers as I was, beware!! Put away in storage for a while two out of my four cinnamon candy knobs decided to absorb moisture from the air and perhaps the glue and gradually oozed their way towards the bottom of the dresser. Ick.)
Best wishes for Thanksgiving! R.
