I have been wondering why polypropylene isn't much easier to source as a 3D printing material. Given its incredible flexibility it should be much more widely used than it is. The price would also likely fall with greater demand. Your dedication and attention to detail are admirable.

PP is about the cheapest raw material is to buy. I was a materials manager in a plastic manufacturer for years. Part of my job was negotiating contracts with suppliers. I was buying high performance PP for around 68 cents per pound. That was after the price of oil went through the roof (PP price is directly tied to the price of oil). Before that I was paying well under 50 cents per pound. If you get into the cheaper PP material, for example T20P100, which is 20 percent talc filled, the price goes down significantly. Which basically means they throw dirt in the material to make it last longer, lol. In comparison, the ABS material we used was of a VERY low cost provider. That material was 1.40 per pound if I bought full truckloads. I can't speak for 3d printing yet, but in injection molding this was about the easiest material to process. You can crank out millions of parts with this stuff and not even show wear on the tooling. The bad part, in the automotive world at least, was that it couldn't be used for much. The vast majority of the material was nylon 6 or nylon 66, which varied between 2.25 and 2.75 per pound most of the time. And with the fillers needed became extremely abrasive, most commonly glass filled. I'm just starting to get into 3d printing. If I decide to start using PP, I'm going to pick up a filament extruder and make my own since I can get it from the last place I worked. Even if I pay twice what they're getting it for I'll still be way under 2.00 a pound and I know where the material is sources and the specific specifications it has to meet. The more I think about it, I might talk to my friend that bought the place I was working and see if it's viable to start producing filament.

I've used some Forefront F43 TOUGH PP (black) myself and was super impressed by it's layer adhesion and surface finish, when printed in 0.1mm layer height it's almost as if it's injection moulded. The nice thing about the F43 is that it can be printed at 200C so there's less warping. Also the layer adhesion is really annoying when it comes to supports on large objects/curved surfaces, the supports are borderline impossible to remove. I used it to create some velocity stacks for inside of a motorcycles airbox as it's properties were ideal for the application (They were designed to snap fit into the airbox + good chemical/temperature resistance).

What bed temp did you use? The manufacturer recommends 110C for the first layer and 30C for the second and subsequent layers. Don't know how I could achieve that.
@ILoveNeeps5 жыл бұрын
I used the 110C initial layer and I think 40C subsequent layers. I managed it with an Ender 3, it took about 20 mins to heat up and I was using a polythene sheet as an enclosure. If your printer is struggling you could try covering the bed with a sheet of cardboard until it reaches temperature.

Thanks - I'll give top insulation a go. I'll also add a significant brim as the corners were lifting. What I didn't understand was the logic behind lowering the temperature after the first layer as, because of the thermal mass of the bed, the temperature is still going to be well above 30C when the second layer prints.

Old video, but I came here because I recently discovered this material when searching for light weight filaments. In my hobby (FPV quadcopters) I keep my quads all under 250g, so weight is essential. The current build that I am doing right now will be super tight so trying to shave all the weight from the 3D printed parts (mainly antenna mounts, camera mounts and such). Ordered FormFutura's Pegasus PP Lightweight, which is supposed to have only 0.75g/cc. If I don't have to 'bulk up' the designs a lot, then the savings should be substantial vs. PLA and TPU that I'm using currently.

Also keeping the silicon sock may help a little. All other settings like 30mm/s for print speed and whatever CNC Kitchen does is what I do as well.
