Yes, but with a few caveats. The major issue is the 3-D artwork needed for these types of projects. Keep in mind that creating 3-D projects with your laser can be time consuming and has a learning curve. If you want to try your hand at creating 3-D artwork, plan on having a lot of time to learn and relearn the features of the software you use.
Profitability of a project is based on making more than one of them. Replication of the project will yield profits if you can sell multiples of the same project. Once the vector cutting files are created, running them over and over to produce multiples is an easy task. There is no doubt that as more 3-D artwork becomes available, that the process of creating highly detailed 3-D models using a laser will grow, and it will be exciting to see more new and creative applications for this technology.
