the melting chamber needs to have ceramic coating to supports the pla  the press does not have that its just brass all the way.

or just apply that oil so it glides

And if I dont have sewing machine oil, anything else ? I have the problem with PLA, didnt print any, the greatest record: 2 layers then stopped extruding.

With PLA, it's very likely you're extruder body is too hot and the filament slumps at the entrance to the heat break tube. (The press extruder cooling is rather weak.) At least that's what I run into.

i tried this whit yellow glow in dark pla and it worked fine if printed slowly .

i tried silver pla but more difficult its more soft.

but the solution should work on most pla and rubber flex

yes only sewingmachine oil i have not tested any other oil.

Re: if you have problem whit pla on the press do this

I have a stock sd4 have only printed pla . Not a heavy user  . I have heard dipping the filament tip in canola oil will improve printing. HAve not tried it.  If you compare msds sheets on various oils you will see MANY are mineral oil.  just with a different label instrument oil knife honing oil sewing machine oil , way oil of course various additives even perfume may be added .

If you do a quick google search of canola oil and pla  you will see a bit of discussion on various forums . People have mentioned grape seed oils and peanut oils as well as the aforementioned mineral oil and canola oil.

The idea here is PLA is corn starch base and a bit sticky when heated. a drop of oil on the tip seasons the innards of the hot end  much as one would season iron cook ware. 
the need for the seasoning depends on the internal finish of the hot end and if it has a liner.


So the need to do this would be based on what hot end you have what material you use.
