To whomever this may concern, I hope this finds you well. I am very interested in printing an object through Shapeways, but ideally I would like to print it on top of another printed object. Do you know if his is possible? Additionally, I am wondering how many different materials Shapeways may print in creating the same object. For example, if my design calls for both aluminum and acrylic plastic, can Shapeways accommodate this? Thank you very much!
