Update: BambuLab PC-FR
Added 2025-03-09 12:40:30 +0000 UTCEarly access (but only few hours) and table update, new line is BambuLab flame resistant polycarbonate (PC-FR). Video link in the table (or follow the playlists).
Comments
Can you send me an example, modified table?

2025-03-29 20:56:52 +0000 UTCThanks for the updated table, Igor! One request I have is to consistently use the unnalealed values in the table (or perhape even better: add new rows with the annealed values). Case in point, when I compare the different PET-CF filaments in the table I see that Polymaker PET-CF is listed as 137 C (with a comment saying that it is only 93 C WITHOUT annealing) and Bambu Lab is 120 C (with a comment saying that the value is more than 200 C WITH annealing). So when sorting the table by deform temp, Polymaker is best, but when looking at the comments, the Bambu Lab is better. Another thing that surprised me was that the Siraya PET-CF has almost double the deform temp compared to Bambu Lab when they are not annealed. This seems strange and definitely gives Siraya an advantage since no annealing is needed. And Qidi PET-GF has almost double the layer adhesion compared to Siraya PET-CF. Would love to see all the PET-CF filaments compared in one video. Whenever I download your updated table, I always add conditional formatting to make it easier to get a sense of the values and move deform temp as one of the first columns, since I think this is a separate property of relevance compared to creep, twisting and bending where these values often correlate to some extent. If you agree, you could consider implementing this by default. Thank you once again!

2025-03-11 08:43:05 +0000 UTCThe reason we use transparent PETG is that it don't have coloring pigments in it and with this the base material is not "contaminated". I work on food engineering department and it's important for us in some applications. I will try to play with the transparency in a separate video.

2025-03-11 06:40:55 +0000 UTCI’ll be happy with whatever you post. For me, transparent filament is only interesting if it is transparent, the mechanical properties are not what I would use as a metric judge between them. With transparent filaments, things like print speed, temperature, orientation affect the transparency, just like layer adhesion or annealing options affect mechanical properties. I’d kinda hoped to see similar testing but know you are swamped with work.

2025-03-11 06:07:54 +0000 UTCIf you are talking about that 10×transparent PETG, the point will be on the mechanical properties. I will not tune the settings, to get max transparency, I will just use default settings, and measure somehow the transparency too.

2025-03-10 21:45:49 +0000 UTCI like the preview! Can’t wait to see how you tackle the transparent filament comparison. I’ve been overwhelmed with options for trying to maximize transparency. Trying that on 10 filaments seems…. Challenging.
