There are many filament suppliers produce at high speed, the filaments are not well cooling and not dried enough, so keep lots of moisture inside .Moisture will make melt strength of filament decreased rapidly , and then bubbles,stringing, shrinking,warping,brittle,vacancy, etc , see some vacancy spread the surface on right vase of last photo above
Some customers said , 3DDPLUS pla black require higher temperature. Yes, that is right.
In traditional plastic industrial, many plastic processing at higher temperature and better melt strength is more expensive than that in lower temperature. The same kind of material which processing in higher temperature means better melt strength that is a key point performance in plastic processing since plastic should be melt flowing to shape. .
3DDPLUS pla has better melt strength, well cooling , dried and post treatment, less stringing, less shrinking, less warping,less vacancy when 3d printing, smooth and shiny model surface.
