I spent a week with their support trying to get my N Scale designs ready for Shapeways to sell my designs. Everything was uploaded and the renders looked good and gave the green light to print. On the first order everything was taken down that my details were too thin and would not survive there manufacturing. Adding the thickness they wanted to the models would ruin the look of the model.
I was able to print these fine on my home resin printer and the details did not break during cleanup, painting or assembly. Apperatly a $150 home use resin printer and real person can outperform a larger international company on quality, durability and handling.
