|3D Hubs Marvin in 4 brands of PLA from Amazon.ca|
|MG Chemicals Label|
|765 grams of MG Chemicals PLA|
First up is the MG Chemicals PLA that I'm using as a reference point. Filament label is a bit basic, mostly just batch numbers and a brief description of the spool contents. Weight wise, the spool itself is about 190 grams of plastic, so the total weight is roughly 1,190 grams of material out of the box. Printing temperature range is 180C-220C, although it will print at up to 230C with some loss of detail.
Next up is the Hatchbox PLA, it comes a plain brown box, nothing special to look at on the outside. On opening it, I was surprised at the level of information included on the label, optimum temperature range, links to the brands social media pages, and the poorly advertized fact that the spool is a Pantone Colour (Purple C). That makes choosing a colour much less of a guessing game than some brands. Spool weight is on the heavier side with 311 grams of deadweight being used just to hold the filament.

For contrast, the AMZ3D is probably the most generic brand of the lot, colour is more of a fiery red/orange than pure red, and it's quite brittle to the touch, making handling a bit tricky. Spool weight is 228 grams with a temperature range of 180C-210C although it seems to work just fine up to 225C.

And lastly is the surprise spool in the group, the 3D Solutech Apple Green PLA. The overall presentation of this filament is the nicest of the bunch, with both a decorated box and brand label on the spool. The real surprise though is the 3D printed filament clip that is used to lock the filament on the spool during packaging, not something you usually see. Spool weight is 180 grams, with a temperature range of 190C-220C, although it prints at 225C without complaints, the 190 is a hard floor, attempting to go below that just resulted in 'air printing' or zero material flow. Amazon's supply of this brand is a bit unstable, the selection of colours seems to vary from time to time.

|3DBenchy in AMZ3D Transparent Red PLA at 220C|
|3DBenchy in 3D Solutech Apple Green PLA at 220C|
As you can see, all 4 filaments print fairly similarly, with only minor variations due to slightly different temperature tolerances. The 3D Solutech PLA suffered a slight extrusion glitch around layer 6 due to the slight temperature drop caused by the below nozzle cooling fans coming online. As for the temperature towers, here's a 2 minute video showing them in sequence.
Overall, I'd recommend the both the Hatchbox and MG Chemicals brands as best quality vs cost, and the 3D solutech as a good alternate if you don't mind a slightly random colour selection. I can't recommend the AMZ3D filament at all, since while I was writing this post, it snapped inside the filament tube on the Micro Kossel below the extruder motors' gearing!
