What is the best source for consistent quality PLA?I’ve used Ultimachine in the past and would have no problem ordering from them again.Before I do– since it has been a couple of years since I last looked– I would like to gather opinions as to the current best source for high quality PLA?North America, please.Thanks!(A bit surprised not to see a “materials” entry on the sidebar. But I could be blind.) http://ift.tt/2esBc36
