Introduction
Material is what your custom part will be made out of. You can select select a material
from a list of common materials or specify a special material. For example you
might select aluminum for an electronic chassis to minimize
weight.
To select a material from a list:
- Choose Job | Material. The material types shown depend on your design. For example, if your part is configured for injection molding, only plastics will be enabled.
- Check Show only recommended materials if you want to see the recommended materials. (Point your mouse to this option for more detail.)
- In the grid select the desired material by clicking on your selection. Use the columns of information* to help you decide on the best
material for your job. Ignore columns not of concern to your requirements. If you don't have any specific requirements, consider selecting the lowest cost (VRCost column) steel, aluminum or plastic. The Availability column shows
approximate time in days to get the material. The
VRCost column shows approximate relative
material cost by weight, but selecting a lower cost material may not always give the lowest cost job**. See more information on materials here.
- Choose the lower checkbox settings as needed.
- Click OK.
* The data presented in the material dialog was collected from several sources.
Although the sources are believed to be reliable, the accuracy of the data is not
guaranteed. The data is intended as a general guide. If one or more parameters are
critical to your design you should verify the data independently. Please
contact eMachineShop with any corrections.
** The lowest VRCost may not yield the lowest part cost because many factors effect the total job cost. For example, a lower
cost material might be harder to machine or be more expensive to ship
due to increased weight. And a material of the same cost as another
might be less expensive because it's weight is lower. The VRCost value is most relevant to job cost
within a similar class of materials such as steels.
