RE:"terms simple enough for us 'mericans to understand"

Not about financials and not apples to apples but this is what I'm talking about...sort of.

Materials:

One of the key differentiators between DMLS and EBM are the materials available for processing. Although you can likely find ways to manufacture materials in either system, it has been seen that there is a natural fit for each technology. Below is a table that highlights what family of materials work well in DMLS vs EBM.



There are uses for all of the materials above so to process them in the most efficient manner you are driven to having both technologies.


Part Size:

Another key consideration is the size of the part required. The optimal size of the part for a technology is driven by the process rate of the machine. How much metal can be deposited each hour? The faster the rate, the larger the parts are going to make sense. The size of the production run may alter this but below is a good guide for reference. The images below are used to represent the optimal size of each part for the technology.



Based on the image above DLMS is best suited for parts no larger than a lemon whereas wire deposition based printers are well suited to parts larger than a watermelon. Obviously, there will be exceptions to every rule but the above is a good rule of thumb for which technology to choose for your project.

If you're giving visual examples of size differences the items should be using the same visual size scale.
