The recommended profit margin depends on the type of part and market. For standard parts sold on generic platforms, a margin of 30-50% over manufacturing cost is usually reasonable. If you offer functional, on-demand, or custom-designed parts, margins of 60-90% are completely common in the industry. For specialized technical orders—such as industrial spare parts, prosthetics, or molds—margins can exceed 100-200%. Remember that the margin must also cover design time, post-processing, shipping, and machine wear across many prints.
