This post aims to create awareness that many filaments are not different from one another, encouraging smarter purchases to drive greater competition and potentially lower costs. Wouldn’t it be great if other could run similar test below on two other brands to see if they get similar results?
I’ve often criticized filament makers for their marketing tactics. Most brands, except perhaps one, use similar tactics, trying to convince us their product is superior when they all come from a few factories in China with only different packaging. I posted an example of this in another thread(link), recommending a low-cost PC filament marketed under different brand names but yielding good results.
My contention is that unless you have verified it yourself, don’t get suckered into marketing hype.
In my quest for the elusive $10 spool, I’ve had varied experiences on Amazon. Thanks to Amazon’s liberal return policy, I return bad spools if I can’t calibrate the filament, sometimes after using 10% of the spool.
The other problem
Some of you have stated that you stick with one filament maker for convenience of not having to worry about calibration. This is understandable, but is it worth spending 2X on a spool? Consider how much you use and decide if you’d prefer the convenience or twice the number of spools.
However, I’ll quickly admit that buying on the open market based on price can create problems if you need to split a print between two manufacturers. If the filaments are not identical, you’ll see the difference when you change spools mid-print.
Here’s what two filaments SUNLU and Overture with spools changed in mid-print look like.
I’ve been testing ways to identify filaments from the same factory with different labels. I’ll share my technique and proof that they are the same for at least two different makers on my example. See the link I posted above for my example on PC filament.
The scenario is this, I was running out of Overture PLA Black which I had just purchased for $14. I simply do not see why I need to spend more than $15 these days but after the one-time promotional price, Overture jacked the price again back up to $18(list is $24). Buh-by!!! Next!!!

Don’t get me wrong, that filament is high quality and it prints well. But why should I overpay. So I go back out to Amazon and start searching for other suppliers. Both SUNLU and JAYO were discounting their products to $13. I only needed one spool but the two looked almost identical in the ads so I decided to purchase both and do a side by side comparison.
Note: I have purchased from both before, and JAYO has been my choice the last three times I needed PLA Black. However, I primarily buy based on price and delivery. Both products in this example were next-day delivery and the same price.
Comparing two ‘different’ brands that look the same.
Methodology to determine factory of origin between SUNLU and JAYO are the same.
I used the same methodology as I did with my PC filament report that I did in the previous (link) post above.

Outer Carton: Same size, same shipping address and same carton design with the tab in the same location.
Identical spools:
From the back, you can’t even tell them apart.
Same vacuum packed bags with same heat seal and dual ziploc seals.
Same Desiccant bags with complimentary filament retaining clip.
Spooled tightly like they were made on the same machine.
The real test. How do they look on the same print when switching mid-print?
So this is really where it makes a difference doesn’t it? Are these two similar enough to make a difference in the print? Well my testing methodology was crude but I will let you decide. Here is the testing methodology.
- Use default Bambu Basic PLA filament profile so neither spool has an advantage. This is so others can perform the same test if they wish to.
- Use a Cylinder and Cube Primitive shape scaled to be 25.4x25.4x50mm as the test model.
- Set the print to Pause at midpoint 25.4mm and swap filaments mid-print. This will simulate the same issue as having run out of filament in the middle of a print.
- Perform the same test by unloading and reloading the same filament spool to simulate changing spools while keeping the brand the same.
Results: Two models were printed using two filaments, while the third was printed with the same filament. At the midpoint, you can barely see where the print was paused. But can you see a difference in quality, shine, or pigment between them? Can you spot which model used a single filament or had the filament changed?

The one in the middle was the one printed with only one filament brand.
So you think now that all brands are all that different or if it’s just the price?
At the end of the day, in my view and with this test, you can see why I do not trust anything I read unless I tested it myself. As an example. PLA+ Really??? Until the industry uses a unified standard of what constitutes PLA+ I call B%llsh*t!!!
