I thought this might interest some of us here. The company I work for just launched a service specifically for small runs called Batch Control.
The idea is that if you’re a business or professional you can print off short series of objects, controlling the z-axis print orientation, scale, number, particle size etc. but since the minimum order is fairly low (20) it’s great for hobbyists too.
I plan on using it for printing off custom robot parts, get the design right iteratively on my @Peachy_Printer (can’t wait to get it!) before ordering a stack of prints in more durable nylon from @Sculpteo .
Disclosure: As mentioned in my post above, I work for Sculpteo, but think this should be of interest to the community
Anyway, enjoy the article, @Engadget says it better than I could anyway!
