Fabricating Custom Scale Models of Actual Aircraft Ships and Cars requires a lot of creativity. Before starting any Scale model project for a client, we must determine whether to replicate the model using an existing donor or to build from scratch. Sometimes the best option is to use a product/material that is already available in the market. Other times, a Car or Ship is so unique that its impossible to obtain any parts what so ever. When do you decide to use 3D printing? When would you build a model from Resin or Wood? Perhaps both?
