Executive summary pitch

What is the purpose of the presentation?

It might not be relevant but perhaps you could showcase your knowledge by noting common issues with solutions for each.

In that case your list is pretty comprehensive.

The only other thing I can think of is to discuss alternatives to fused deposition modelling, such as CNC mill. Most peasants I mention 3D printers to think that the plastic is cut out of a bigger block, so a making that distinction might be good.

Also, I'm sure if it's worth discussing laser sintering like the form 1 or whether that opens up a big can of worms.

I may be wrong, or just poor. but I think getting up past the $2000 USD range makes it more than common consumer grade. Never mind powders and liquids. At about a grand I start to flinch, maybe that is just the peasant in me .

I may start another thread and I don't mean to troll but it seems to me that if you are doing prototyping or single runs then a 1000 dollar filament printer vs. a 3000 dollar filament printer does not make that much of a difference.

Back to the point. The conclusion of the presentation may be to show that for the price of an xbox one can enable micro manufacturing. It depends on the audience. How it empowers people or whether there is any money to be made is out of scope.
