Could I propose an option for priority printing for WSF? I make camera accessories that are very technical and require a lot of tweaking. It takes me usually 3 tries to get the product right. I spend 5 days for each tweaking and about 14-16 days waiting for the shipment. If I had to tweak 3 times, that is a total of around 60 days to develop my product. Usually I get notified after 7 days of submitting a model that it has gone into production, then 3 to 5 days later it is shipped. 4 more days to received package. My dream would be to get a prototype overnight! I could finish a product in 18 days! but I know it's not practical for overnight. What I propose is to set one machine aside for priority printing with a 3 day production, down from the average 10 days, cutting 7 days of waiting. With 3 tries, this would save me 21 days out of the normal 60 day process. I would be willing to pay double the cost for priority printing. The queue could be setup to accept priority orders during checkout only when there is enough space for a 3 day production. Being able to develop a product faster would justify the additional fees for me. Another reason why I would like priority printing is that I am constantly moving from city to city each week or month while I go hiking or traveling, and having to stay in the same place to wait for my prototype limits my mobility. My goal is to use 3D printing to support my travels. Currently my 1st set of products supports 15% of my travel costs. I hope that my next 2 sets will increase this to 50%.
