Join AON3D's 3D printing application and materials experts for a 30-minute session that covers all the key information
The cost of materials are an important factor when calculating a 3D printer’s total cost of ownership. Closed material systems, especially for industrial 3D printers, often mark up the cost of their materials, sometimes as much as 500% for simple commodity polymers. To help disguise the costs, these proprietary materials are often sold in volumetric (cubic centimeter / inch) increments instead of the industry standard weight-based pricing. So how do you convert this into a cost you can compare?
How to Convert Cubic Centimeter Filaments to Kilograms for Cost Comparison
First, you will need to find the filament’s Material Data Sheet (MDS) or Technical Data Sheet (TDS). Here you will find the material’s density or specific gravity, often stated in grams per cubic centimeter. To help, we have provided a list of common materials and densities below for reference. Now that you have the density use the following equation or use the calculator below.
Convert cubic cm filament to cost per kg.
Reel size: kg
Common Material Densities & Open Market Pricing
|Material||Density (g/cm³)||Cost per kg (USD)|
|Carbon Fiber (10%) Nylon||1.17||122|
|PEI (ULTEM™ 9085)||1.34||285|
The Value of Open Material Systems in Industrial 3D Printing
Open material systems like the AON M2+ High Temperature 3D Printer provide more material options compared to closed systems while providing significantly higher return on investment. Assuming 15kg of ABS used per month, a business can save upwards of $34,000 on annual basis by using an open material system. Materials are not the only factor when calculating the total cost of ownership of a 3D printer, find the equations and which expenses should be considered here.
