Degradable tree-based filament: Extrudr BDP Pearl review! #Filaween2


What do you get when you take all unique traits
of PLA and try to amplify them – well, you get something like Extrudr BDP. Selling at a decidedly premium 56€ for a
one kilogram spool, it’s a biopolymer that is, as I understand it, related to the polymers
that hold trees together. It’s biodegradable in a household compost
pile, unlike PLA, which needs very specific conditions. According to Extrudr, within four months in
the compost, almost half of the material will have broken down. I couldn’t test this claim yet, but might
do in the future. At the same time, BDP is rated safe for food
contact, but as with any 3D printed part, getting them clean including the ridges the
layers create can be challenging in a handwash. BDP sticks incredibly well to buildplates
and itself, can be printed at extremely low temperatures down to 160° and show very little
warp, so it’s ideal for huge prints and unheated buildplates. I ran the calibration 3Dbenchies at 160, 180
and 200°C, and they all printed perfectly! I did not expect BDP to perform well over
this wide of a temperature range and the only differences were a slightly more dull finish
on the 160°C one and some some slight hair growth on the 200° Benchy. For the rest of the prints, I went with 180°,
a 55° buildplate, 110% flow and the cooling fan turned up all the way. With this being the “Pearl” version of
BDP, it comes with a decent shiny, metallic look. It’s not of the in-your-face-type like some
other shiny filaments and resembles, well, Pearl and nacre, so I printed a seashell and
it did turn out beautifully! No supports on the inside. Print quality otherwise is solid as well,
so BDP earns the second set of 5 flaming stars here. Mechanically, it’s decent, but it’s not
great. Impact resistance is slightly better than
PLA, but it is a bit softer and doesn’t quite get a highscore for strength. Thermal resistance is very comparable to PLA
despite the lower possible print temperature. So mechanically, that’s only three and a
half stars, BDP is rigid, consistent and predictable, but wouldn’t be my prime choice for heavily
load-bearing parts. Overall, that sums up to five solid stars,
making BDP a great choice as a straight upgrade path from PLA.

  1. Sounds very cool 🙂 But it's very expensive… you can get economy pla from colorfabb for like 16 Euro/kg and it prints like the expensive version 🙂

  2. Cool review ! I'm just printing on my own Dolly 😉 Just a question, do you plan Filaween review of some budget PLAs like Genius or Mladec ?

  3. Did you get a chance to compare BDP Pearl vs. the normal "Extrudr Greentec BDP"? I think the results might differ drastically.

  4. that's a very cool filament. Their website is confusing though. You can set your cart to USD but you can't ship to the US. Oh well I guess I have to pass.

  5. Man thanks for your filament reviews, Tom. Pretty expensive stuff. I hope it's because they don't produce it in such high volumes as standart PLA… yet.

  6. Recently I've printed a 3D map with this filament. I think I've printed it a bit to hot, as I had the stringing you also ended up having on the 200° C printed Benchy. But overall, I really like that Filament a lot!

  7. @Thomas_Sanlander There is one more piece of info i think we all would like to hear in your videos and that is the total print time. My reason for wanting this is in my attempts to increase print quality with different filaments i'm often playing with the top speed settings in search of a good middle ground between excessive print times are acceptable print results. Keep up the good work, your videos are great being full of technical info but also just entertaining as well. Hope to someday buy a printer designed my you personally.

  8. Hey Tom, any chance of you testing Polish made Devil Design filaments? They are dirt cheap here in Croatia 🙂 Thanks

  9. I think you shouldn't have tested the "pearl" version. The normal color versions claim temperature resistance of 110°C and can be printed hotter. They might be stronger too?

  10. Thomas my suggestion, I understand the beauty of the blurred background, but if your plane of focus is so small is hard to distinguish prints detail [0:58]! keep up the good work!

  11. Got another idea for you "tests". Like the boiling water test is subjective as f***. You might go to more mechanical property but just strength. How about friction and wear.

  12. Pearl or… what?! Had to turn on closed caption to make sure a certain word wasn't said. I'd never heard of nacre before this video. 🙂
