Agree - Here is the history: We used the term "Fused Deposition Modelling" and the abbreviation "FDM" on the RepRap website when the project started without knowing that they were Stratasys trademarks. In March 2008 Stratasys sent me a polite e-mail pointing out their trademarks and asking us not to use them (I will supply a copy on request, but will not post it as it is Stratasys's copyright - contact me). I then invented the term "Fused Filament Fabrication" and its abbreviation "FFF" as direct free and open equivalents (see the RepRap Licence). We did a global edit on the RepRap website to make the changes. - Adrian_Bowyer
