I have to print some parts in nylon (Taulman 645) for an university project and im concerned about how a brass nozzle will handle it. I read that nylon or PLA filled with fibers are very abrasive to the nozzle but ¿Is nylon abrasive it self without the fibers? ¿How abrasive could be compared with PLA? ¿Is necesary also a steel nozzle? I compared Hardness Shore D and they are almost the same, but i dont know if this is a good measure of its abrasion to other materials. Hardness, Shore D 59.0 - 77.0 http://www.matweb.com/search/DataSheet.aspx?MatGUID=ab96a4c0655c4018a8785ac4031b9278&ckck=1 Hardness, Shore D 79.0 - 82.0 http://www.matweb.com/search/DataSheet.aspx?MatGUID=726845c457b94b7cafe31d2e65739e1d
As far as I know Nylon isn't abrasive at all. I'v printed with Taulman 645 before and did have no problems with it (except for bed adhesion). The hardness of a material is only applicable when it's solid.
