1. Hello !

    Thanks a lot for this sutdy. although it contains bias , this study deserves to exist .

    By cons there is something I do not understand.
    Why did you use the same print temperature for all filaments ?

    It is well known that each filament has an optimal printing temperature . Even on a particular brand , according to the color, the temperatures vary .

      Hello Sylvain,

      Each filament does have an optimal printing temperature, but the supplier usually just gives a range of temperature: e.g. 180-230C. I made sure that the temperature I chose (200C) was in every filament suppliers’ range, but I did want to keep the temperature constant across filaments to prevent another bias, especially for performance testing (different printing temperatures may lead to different mechanical performances).

        I agree, the printing temperature should have been specified by each manufacturer.
        For instance your could have took the center of the recommended temperature interval unless otherwise specified.

        I put some brand in a disadvantage position. For example Colofabb incorporate PHA in their PLA which can affect the temperature and performance compared to other brands. UV resitance etc.

        However, my personal appreciation of ColoFabb perf and quality is not very good. Filament texture tend to raise friction, more difficult to push. Harder to extrude fast and tend to warp more than other brands. It has tendency to jam in E3D hotend. Not my favorite. But the diameter tolerance is good.

        Other spec to take in account and easy to check is the filament diameter tolerance, roundness. It can have a great impact on the print result if it is too inconsistent.

        Color consistency between rolls is also important.

        Definition of red for instance has a very large interpretation… turn out to be more yellowish than orange sometimes.

        Color plays a role in quality too. For instance they can put a lot of crap in the black but it is more difficult in natural color.

        You can checkout this site: http://www.3dsettings.net/fr/
        They have a great idea about sharing 3d printing settings, but the site need more love.

        you did a great job

          Hi Pierre, thanks a lot for your insight, it will be helpful for us to refine the procedure (influence of the hotend model, diameter tolerance, influence of colors).

          We had seen the 3D settings website and we think it could be useful if they manage to get *many* datapoints (though you would need to significantly process the data to bring out the conclusions). But what we tried to do was to have a consistent procedure across filaments, rather than an anecdotal approach to the testing. In any case, both efforts are improving the user’s understanding of materials!

  2. Hello 3D Matter,

    We are company who is manufacturing filament for 3D printer and we are interested to submit our filament for a comparison test with other manufacturer of filament. How can we participate on the comparison testing (in case there will be another testing will be perform) and is there any registration fee require?

    I’d like to check out Dutch Filaments, but I couldn’t find any online retailer except one which sells rebranded Dutch Filaments for nearly twice the price mentioned here. Can you share the link if you know a reasonably priced source? Thanks.

    • 3D Matter

      We used reprapworld.com to get Dutch Filaments. They seem to have changed their branding since our study though, but it probably is under the name “REAL PLA” now.

      • Balu

        Dutch Filaments is a private label manufacturer. Their filaments are being sold under a lot of different names…

        • 3D Matter

          Hi Balu, at the time of the study they were still selling under their brand on some retail websites. It is not the case anymore as you are pointing out, and the “REAL PLA” filament from Reprapworld.com is actually not them.

  4. Linas

    I have asked reprapworld.com, they said REAL filament is not related to dutchfilaments.com. There are two similiar manufacturers (dutchfilaments.com and dutchfilament.com(which is REAL filament)) So actually, which filament did you test?

    • 3D Matter

      Hi Linas, the “Dutch Filaments” we tested is definitely from the company Dutch Filaments. On the other hand, the “reprapworld.com” filament we tested has apparently since been rebranded to “REAL filament” or “Dutch Filament”. Sorry for the confusion, changes that happen in the market after we publish the studies is out of our control!

      • Linas

        I have tried contacting dutchfilaments.com, but i got no answer from them. Do you know where I can buy their production?

        • 3D Matter

          Dutch Filaments is only a white label supplier, meaning that they don’t sell directly filaments to individuals, they sell to filament suppliers who have their own brands. If you are a distributor then you can contact them for bulk order. Otherwise I am afraid you would have to find a distributor that sells their material, but it is a bit tricky since they will not advertise who their distributors are.

  5. You have done a good research about the comapnies. Colorfabb is good if you want to spend more money on filaments. But for the limited amount, I would suggest you to go for Innofil3D. I have used filaments of different companies but Innofil3D filaments are best suits to my printer. Its looking like my printer is addicted to their filaments.
