MatterHackers Pro PETG Filament Review

For those curious about how we got to our conclusion, we review filaments using the following guidelines:

Each and every spool is brand-new and unopened.

Our first print is always a 3DBenchy. We use this to check for any inconsistencies in quality, color, and finish. After that, we print a few other models, the results of which we present to you. We slice the model using the latest version of PrusaSlicer. We do not post-process the prints in any manner, we simply remove them from the bed and cut off any support materials.

We start with the manufacturer’s recommended settings (where available). When the manufacturer offers a range of values, we go for the arithmetic mean. Therefore, if we are given a printing temperature range of 200-220 ºC, we would print at 210 ºC (unless noted otherwise).

For this review, we used an Original Prusa i3 MK3S in stock configuration. Statements regarding print quality are based on the printer’s ability and reputation to successfully print a wide variety of other filaments and models.

We would like to mention that every spool of filament can be slightly different, and filaments often vary greatly even within a small range. Simply fiddling with a single setting like retraction can have huge effects on print quality. This can make the difference between a disastrous fail and a wondrous success.

So, if you own a spool of this filament, we invite you to contribute in the comments below! Did you manage to get your prints to turn out? Did you have an interesting or strange experience? Let us know – we’d love to hear from you!
