Aluminum 1.75 filament eats nozzles?

Aluminum 1.75 filament eats nozzles?

Postby Guinness » Sun Dec 13, 2015 2:58 am

I've heard using the metallic powder filaments causes excessive wear on the extruder nozzles.. Can anyone out there tell me how often I'll be going thru tips? Should I buy 1 or 2 or 5-10 for a 500 gram roll of aluminum filament? And, will anything else get extra wear?? This probably isn't the best place to ask this, but I'm sure others would also like to know, should they decide to use this stuff.. Since I'm still awaiting delivery on my printer, any info on normal wear for tips would also be appreciated. If you are looking for the best possible results, how often should you change the tips?

... Aluminium shouldn't be this big a problem - filament filled with wood- or ceramic-dust is much more abrasive and they print some kilograms woodfill filament without issues :wink:

A few basic tips are as follows:
Wet sanding helps to reduce sandpaper clogging and reduces heat buildup. Although messy it really helps. Just make sure your using waterproof sandpaper...



Use a hard/flat surface. If you have a piece of granite or a sheet of glass use that. The smoother the surface is the easier it is to polish a flat item. This does not apply for non-flat items unless you want the bottom smoothed out.



Always work your way progressively up the sandpaper grits. It takes longer but the results are worth it. Higher grit sandpapers are not intended for removing large quantities of material and will wear out very quickly. Use the low grit sandpaper to clear as much material as possible.



While optional I like to rub my models down with "Nu Finish" liquid polish. This forms a very nice glossy shine and also protects the model against tarnishing... unless you want the model tarnished then skip this step!



Hope that helps some when it comes to polishing up metal models. While it can be a bit time consuming the end result is well worth the effort! When starting out I highly recommend you use a flat model to practice on as well as make a spare so just in case you mess anything up you have not affected the final model!



In the near future I plan on touching on tumbling models and the various medias you can use and some of the advantages and disadvantages to this method over sanding.
