At what width do you cut the plastic strip from the bottle?<\/p><\/div>

The width of the cut depends on the thickness of the bottle wall, as a general rule:
Thickness(mm)->Width(mm): 0.2-><\/strong><\/strong>10, 0.25-><\/strong><\/strong>9, 0.3-><\/strong><\/strong>8, 0.35-><\/strong><\/strong>7<\/p><\/div><\/div>

How do you make the strip round?<\/p><\/div>

At 195\u00baC and about 25cm\/min the PET plastic strip is bent into a straw shape by force, the plastic does not melt at any time when the filament is being made, only when 3D printing is when it melts at 255\u00baC.<\/p><\/div><\/div>

How do you get such clean results with bottle filament?<\/p><\/div>

I clean the plastic thoroughly at every stage of the process; before cutting the bottles, I wash them with soap and water, and use a solvent if there are any traces of glue.<\/p><\/div><\/div>
