PolymakerPC-PBT Filament 1.75mm, Black Polycarbonate Filament 1.75mm PBT Blend, 1kg Cardboard Spool - Low Temperature Toughness & Good Chemical Resistance PC Filament 1.75mm

By far the best filament I have ever used, strong, rigid, prints fantastic. 270 nozzle, 110 bed and 50 heated chamber on a Qidi ifast.Couple things to keep in mind, works better with large nozzle (.8mm) tends to clog my .2mm which means that it doesn't work great for fine details like a gear that I was trying to print with really fine teeth, will end up using PA12 for that instead. Using it for supports isn't terrible to break free (~12-15%) but will look at adding PVA in the future for easier removal.Why use anything else for functional parts, blows ABS/ASA and PA12-CF out of the water...

The PC/ABS blend is one I use pretty frequently as it’s reasonably strong and also can be printed with a nice looking shiny finish. In terms of print difficulty, it’s somewhere between ABS and PC. The size and dimensions of the model you’re printing will also greatly vary the difficulty level. The larger and taller your model is, the more likelihood of warping. Also, chamber temperature must stay consistent throughout the whole print. An enclosed build chamber is almost required due to how easily it warps with any temperature fluctuations or airflow. In terms of strength, it has respectable bend and impact strength and can hold up well for prints being subjected to the elements.Best Used For——————- Smaller prints requiring a durable, high quality production-like finish- Applications requiring Impact Resistance- For use in high humidity environments- Prints needing higher temperature resistance- Everyday use itemsNot recommended for——————————- food storage- for use around acetone- large and/or tall prints (due to warping)My Recommended Settings————————————- 280c nozzle temp- 85c bed temp- 0% fan speeds (all)- Use enclosure

An all around filament for demanding applications. Prints warp free like PLA+ on my Bambu Labs X1 Carbon.Engineering plate, PVP glue stick, 250C Nozzle, 110 C Bed, enclosed chamber ~45 C, 0.2mm layer, max 50mm/sec print speed. Supports separate easily, good detail with step files.

I tried other brands and I thought I was going insane trying to get it to work this one is supper durable and easy to work with yes it's a little more expensive but it's way better than trying to get another type to work out

The media could not be loaded.  Don't get me wrong, this stuff has great impact resistance on thicker parts, but the thing that really annoys me is the cracking. Even on a freshly dried spool i was having a hard time getting parts that needed to be screwed together or attached to something to not crack during the fastening process. This is probably mostly due to it being a stiff filament, but even the filament being fed into my direct drive would often break off mid-print instead of flex, which is odd because it is usually pretty bendable right off the spool, but there would be extremely brittle sections that would just snap off the spool entirely almost like really old pla.This ended up happening 3 times, ruining 3 rather large prints and wasting a ton of filament in the process. Pretty sure i got a funky spool, because some parts would flex and stretch a bit rather than snaping outright, but others would be extremely brittle and just snap and fragment. It wasn't even an issue of layer adhesion because the cracking wouldn't occur between layers, and all parts were annealed at 90c directly after printing. I'm tempted to buy more to see if i just got a really bad spool, but I'm not sure how i feel about this stuff considering how inconsistent the quality of the spool i got was, and i would advise buyers to watch out for bad batches of filament.Update: Polymaker was kind enough to send me a new roll of filament after seeing my review, and after opening it, drying it, and attempting to load it into my extruder, i heard a snap and saw a section break off like dry spaghetti. A few prints later I had another failure due to filament snapping during a print, and cut off the remaining section to check for if it was brittle, and made the following video of the results.Adding a star for the great customer service, but I'm pretty bummed that this new spool is going to have the same issue as my last one.

J'utilise couramment des filaments ASA et NYLON. Pour quelques pièces j'ai besoin d'une résistance supérieure a l'abrasion. J'utilise une imprimante Anet a8 ( lowcost...mais déjà imprimé plus de 20kgs de filament, principalement de l'ASA ).Ce fil Polycarbonate:Impression très facile, aucuns problèmes . ( Rien changé même pas la buse qui a quelques heures de fonctionnement )Températures a 260° et 90° pour le plateauVitesse d'impression 30mm/sRecuit 4H a 90° et refroidissement dans le fourPas de déformation, j'ai pu mettre les écrous sans soucis (photo)Maintenant a voir l'usure des pièces en fonctionnement.Pour moi c'est un très bon filament, un peu cher mais peut être utile pour certaines applications.Je recommande

バイクの部品を作って使用していますが100-150℃くらいで3ヶ月ほど壊れることなく使用できています。積層面と密着性もよく満足です。

Facile à imprimer, ne wrap pas, et est d'une résistance impec, je vais enfin pouvoir faire des pièces mécaniques :)Sur la photo, j'ai essayé de casser la pièce avec deux pinces, et il a fallut que j'y aille fort ! (en torsion je n'y suis pas arrivé)L'axe est mal imprimé, pour les petites surfaces, il faut ajouter un temps de refroidissement, sinon ça dégouline comme on peut le voirMes réglages :bed: pei texturé - colle baton (fournit par prusa) - 100degbuse : 260 degfan : offvitesse : 50mm/spremière couche : 0.1deuxième couche : 0.2remplissage : 20% rectiligneperimètres : 3couches solides : 4bordure : 5mm (surement non nescessaire)enceinte close mais non chaufféeUpdate: avec un temps d'impression min par couches de 20s et sans bordures, résultat nickel (cf nouvelle photo)

hard to print, looks strong, but almost not sticking to bad and like wrap like hell compare to the eSun brand. i just wanted try my luck with PC-FR compare to the PA-CF.

ブラックを購入。265℃ノズルを購入して試してみました。（2022年3月現在欠品中のようですが）プリンターに付属のノズルは使えないそうです。カーボンファイバープラットフォームにケープスーパーハードを吹き付けて使用しています。スライサーは製品付属のFlashXPrint正直難易度はかなり高めで，サポートはライン型でパラメータはデフォルト，スライスはエキスパートモードでパラメータを調整する必要がありました。積層ピッチ　0.27mm（もっと薄くても良いとは思いますが）ノズル温度　260℃プラットフォーム温度　100℃印刷速度，樹脂押し出し中は40mm/s，押し出していない時は50mm/sラフト　マージンは10mm，モデルとのスペースは0.05mm冷却ファン　起動しない（必須っぽいです）壁　有効軽くて剛性が高い印象です。糸引きもほとんどありません。少し色ムラが出てる様に思いますが，気になる人がいるかも，というレベルです。価格と扱いの難しさを考慮して星をひとつ減らしましたが，3Dプリンターというのは最適条件を探るのも楽しみのひとつと捉えれば満足のいくものだと思います。
