This is a relatively new industry and as I think about it one of the problems of purchasing filament is that there is not a "standard" to go by, that I know of. Another problem is that in most cases if you ask the vendor you are using what the make up of the compound is or who maker of the filament is, they do not know. So when we go to purchase said filament we really have no way of telling what we are getting or how well it will work in our machines. Also the vendor could change suppliers so the quality could change and we would not know it until it is purchased and tried.
I wonder if it would be a worthwhile project to come up with "our own" list of questions to ask a vendor? So that when we report on a filament we would have some sort of guideline to go by. I know that I am stating this as a simple joint project but it is not. For instance I do not even know what composition makes the best PLA for 3d printers. For reference http://en.wikipedia.org/wiki/Polylactic_acid
This sounds like a lot of work so perhaps just keeping it simple with a use / no use endorsement would be better.
What do you think?
