One of our designers at WhiteClouds has designed a 3D-printed architectural model that is a futuristic city named Tower City. The concept was based on a self-sustained resort that could be built in a remote location.
First, we take a 3D model of the home and send it to the printer's interfacing software, which slices the model layer by layer and determines how the layers will be printed. Then, a layer of powder is deposited and bound with glue. A fresh layer of powder is deposited and the process repeats until the model is complete. The model is then removed from a layer of unbound powder which acts as support material around the model. The part is then infiltrated with liquid super-glue to bring out the colors and strengthen the piece.
We used the different printers for the different strengths in materials. Horsley was able to print a lot of the smaller parts off of the ProJet that wouldn’t print in the sandstone material. We also used two printers for the look of the different materials; color verses finish. We also wanted to show the capabilities of using two different printers together.
The base and the shelves were all done on the ProJet 660 (sandstone). The two main towers and the bridge were done on the Connex500. All of the little pieces were done on the ProJet 3500.

Horsley said, “I designed the model in Maya based off of a couple of pictures I found on the web. The biggest challenge was trying to use the different materials for different parts and making sure they all still fit together in the end. The most fun part of this model was putting it all together after printing. There were about 53 separate pieces all together. So seeing the final print all go together was very rewarding.”
