Looks like German RepRap, now has Nylon PA6 Filament available in 1.75 mm. Is this a new type of Nylon, or is it similar to other nylon filaments out there on the market? Has anyone ever tried printing with this stuff? It's priced at 49.94 EUR for a 1 KG roll. Supposedly it is more durable than ABS. What type of prints would you guys suggest using this stuff on?
