So how much does 3D printing cost?Our most common question after ‘Hang on, explain how it works again?’, is ‘How much does it cost?’. This is also another difficult one to get your head around as the cost based on volume of material, not complexity of the part like in traditional methods of manufacture. This means that the cost of your part depends on the type of material, and the volume of the part. There is also support material to take into consideration.Controlling volume to keep costs down Volume works in a beautiful way, if you reduce the size by 25%, you reduce your part cost by 58%, and if you reduce your part size by 50%, you reduce your cost by 87.5%! This is due to the cubic relationship between length and volume. For example: If you have a cube of 1cm sides, you have a volume of: 1cm x 1cm x 1cm = 1cm ³ With a 25% reduction, you will have sides of 0.75cm: 0.75cm x 0.75cm x 0.75cm = 0.42cm ³ (a 58% reduction in volume, and therefore cost) scaling_down
