1 English review written for FormFutura ReForm rPET White

Slow and not particularly pretty, but good mechanical properties and consistency

Rated with 4 out of 5 stars.

I've been using this filament for a while now, for functional, structural parts that are designed to be watertight and used outside. For this application, I think it's a very good filament, however there are some downsides/challenges.

It's important to note that this filament is not PETG; it is rPET, and from my limited understanding of these things, the different chemical structure makes this stuff a little harder to print, but can lead to stronger parts than PETG.

Like other reviews I've seen on this material, it likes to be printed hot; 230 degrees C or thereabouts, and slow; I print at a maximum of 40 or 50mm/sec on a 0.4mm nozzle and stock hotend etc.

I've seen this is a little prone to warping on larger models. If you use Cura, you can mitigate this by enabling the 'Alternate Wall Directions' setting, under the 'Experimental' tab. Obviously good bed adhesion is critical in this as well. It may take a bit of experimentation with settings like 'initial line width', 'initial layer temperature' etc. to get this right. I usually do an initial layer temperature of 245 deg C to help it stick to the bed (glass in my case).

If your application is similar; printing strong parts for exterior use, then I thoroughly recommend this filament. If you want smooth looking, pretty parts for aesthetic models, this is probably not a good choice.
