Passive income: NO

Earning passive income solely from 3D printing custom manufacturing and prototyping services is challenging and not common. While it is possible to automate certain aspects of the process, such as order management and print scheduling, achieving a completely hands-off, passive income stream is rare. Most individuals in this industry actively manage their operations to ensure quality, timeliness, and customer satisfaction. Setting up automation tools and outsourcing tasks can help streamline operations, but ongoing involvement is typically necessary for success. It is important to note that reaching a truly passive income level in this hustle may require scaling up significantly, which can be capital and resource-intensive. While there may be some outliers who have achieved passive income through this hustle, for the majority, it involves active participation and management. Unrealistic expectations of easy passive income without active involvement are common myths associated with this business. Costs range from $500 to $2000 for setup, and time to profit can vary but typically ranges from 3 months to 1 year.
