BASF Ultrafuse InnoPET has excellent layer bonding properties, while some materials may be much weaker along the layer lines and split if force is applied along the grain, PET offers a much stronger bond between layers offering higher tensile strength than both PLA and ABS. PET is very rigid and will resist bending, it will break rather than bend and deform like soft plastics. BASF Ultrafuse InnoPET does not give off pungent fumes like ABS does.

BASF Ultrafuse InnoPET is the best PET we have tested to date and it naturally has some inherent transparency in it's colour which hides slight imperfections.  Surface quality is equivalent to OEM filaments if not better.  Best of all,BASF Ultrafuse InnoPET is 100% compatible with Ultimakers in filament diameter and spool size. It even uses standard PLA profiles, so no additional configuration is required for reliable operation.
