Micro American Rail Prototypes

Micro American Rail Prototypes are Z scale kits of American heavy equipment and American railroad equipment not available in the model railroad consumer market. I'm a heavy equipment Industrial Designer and right now that gives me very little free time. This store is just a hobby and I try to add to it when time permits. I have gotten many requests for N scale work and would like to someday venture into that area. But for now, its a matter of finding free time to do anything in any scale.

I strongly recommend cleaning parts for all my models before painting in order to get the support material used in the printing process off the parts. You can go on Shapeways forum for many different solutions for cleaning fine detailed parts martial (AKA FUD).

Personally I find 10 minutes soaked in 90%+ isopropyl alcohol in an ultra-sonic cleaner (about $20 on Ebay and the likes) works best. Rinse parts in cold water right after taking them out of the cleaner to wash off the alcohol as it will ruin the parts if left on. Let completely dry before priming and painting. You still might have to scrape/sand away some of the support material before priming to get a nice smooth surface.

I also recommend using Dupilcolor Filler Primer (Part # FP101). It dries fast, sands real easy and helps smooth out the surfaces without taking away the detail when applied in light coats. Shake can for at least 2 minutes before use. I’ve tried them all and this filler primer works the best. It has a very fine filler, perfect for z scale. You can apply any paint on top after its dry. I would still recommend 24 hours before putting paint on to be on the safe side.  

If you have any questions, please feel free to contact me.
