When it comes to 3D printing, understanding how to calculate the cost of a print is essential. While the cost can vary based on several factors, having a clear understanding of the calculations involved can help ensure that you are pricing your prints appropriately. In this article, we’ll take a deep dive into how to calculate 3D print cost and provide actionable insights that will help you determine the right price for your 3D prints.
Determine Material Cost
The first step in calculating the cost of a 3D print is to determine the material cost. This involves calculating the amount of material used in the print and the cost per unit of material. Most 3D printing software provides an estimate of the amount of material required for a given print, and you can use this estimate to calculate the material cost.
Factor in Printer Depreciation
The cost of printer depreciation should also be factored into the cost of a 3D print. Over time, 3D printers lose value and will eventually need to be replaced. To calculate the cost of printer depreciation, divide the cost of the printer by its estimated lifespan in hours. Then, multiply this number by the number of hours the printer has been used for the print.
Consider Design Complexity
The complexity of the design can also affect the cost of a 3D print. More complex designs may require additional support structures, which can increase material usage and printing time. This, in turn, can increase the overall cost of the print.
Factor in Post-Processing Time
Post-processing, such as sanding, polishing, or painting, can also add to the cost of a 3D print. You should factor in the time it takes to complete post-processing when calculating the cost of the print.
Calculate Print Time
The amount of time required to print a given object can also affect the cost of the print. Most 3D printing software provides an estimate of the print time, and you can use this estimate to calculate the cost of the print based on the hourly rate for your printer.
Determine Overhead Costs
Overhead costs, such as rent, utilities, and marketing expenses, should also be factored into the cost of a 3D print. You can calculate your overhead costs on a monthly basis and divide this by the number of prints you expect to produce in a month to arrive at an overhead cost per print.
Once you have calculated all of the above costs, you can add a markup to arrive at the final price for the print. The markup should cover your overhead costs and include a profit margin.
Calculating the cost of a 3D print involves determining material cost, factoring in printer depreciation, considering design complexity, factoring in post-processing time, calculating print time, determining overhead costs, and calculating markup. By following these guidelines, you can arrive at a fair and accurate price for your 3D prints that will help you build a successful business in the 3D printing industry.
