Example:

Let’s assume you purchase a $1500 3D printer and plan to use it for 8 hours per day over two years. Ignoring repair costs, electricity, and other variables for simplicity:

• Total operating hours: 8 hours/day x 365 days/year x 2 years = 5840 hours
• Hourly machine cost: $1500 / 5840 hours = ~$0.26/hour

Therefore, for a 3D model that takes 4 hours to print, you’d need to allocate $1.04 to account for the machine’s upkeep. This simple calculation demonstrates how the cost of the printer is distributed across its operational lifespan. This is one of the biggest factors that will effect your 3D printing prices.

1.2. The Blueprint: The 3D Model Itself

The 3D model is arguably the most crucial factor influencing 3D printing cost. Its complexity, volume, and design intricacies directly impact material usage, printing time, and the need for support structures.

1.2.1. Model Volume

The volume of the 3D model determines the amount of material required for printing. Larger volume translates directly to higher material consumption and, consequently, increased cost. Hollowing out the model can significantly reduce material usage and printing expenses.

Example:

A 3-foot hollow model might have a lower volume than a solid 1-foot model, leading to lower material costs.

1.2.2. Complexity

The intricacy of a 3D model plays a significant role in determining printability and the need for manual intervention. Complex geometries, intricate details, and delicate features often require support structures, which add to material usage and post-processing efforts.
