PET (Polyethylene terephthalate) is the well-known PET bottle material. This recycled material is a food-approved grade and has a natural transparent blueish look. We predict a bright future for this material: it has excellent 3D printing properties and good mechanical characteristics. We added colors so you can make prints with a nice translucent and decorative look.
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. InnoPET does not give off pungent fumes like ABS does.
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, 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.
