ERYONE Polypropylene Filament 1.75mm +/-0.03mm for 3D Printer, 3D Printing Filament PP 900g/Spool, Black

I’ve used a lot of different filaments, and ERYONE’s Black PP is one of the better polypropylene options out there. Packaging was solid, spool came clean and tangle-free, and the filament itself feels consistent. PP can be a little tricky to print, but this stuff behaved better than I expected. I got the best results with a slower speed and a good adhesive surface, and once it was dialed in, the prints came out strong, lightweight, and flexible just like PP should. Layer adhesion was surprisingly decent for this material, and the black finish looks smooth and professional. If you’re wanting to get into PP prints—hinges, caps, functional parts, anything that needs toughness—this filament is a great option. Definitely worth trying, especially at this price point.

Gosh this stuff is... Interesting let's say. Had troubles but I expected it. Bonds nice to Poly sheets I bought on Amazon. Kinda like a big sticky piece of tape. Near impossible to remove from tape so whatever your print side touching the build plate is, expect an odd glassy plastic tape look. But yes it prints fine. I had heated chamber about 65c. I forget other specs but I used the mod specs on the box. Nearly indestructible stuff. Limited use or needs but it fills a niche. I think I printed an 8 or 10 line outside brim. A few failures but by the end printing a a roughly 1.5x2 in part only one or attempts pulled up. Mostly because I used a partial pp sheet and part was near the edge and it pulled it right up. If I stayed at least 2" from edge, no issue and little pull up. Play with, expect failures but it absolutely can be printed

Don't order filament when you're really tired. I thought I'd ordered polycarbonate. Surprise when I opened the box and it was polypropylene. Anyway, I took it as a sign to try something new. Did some quick research and realized this stuff doesn't stick well. I tried a few different things and got it to stick well on an epoxy coated plate after slowing down the first layer a bit and increasing the first layer temp. After that it printed really nice. Objects feel pretty strong yet flexible. Now I'm finding some real uses for this stuff and will be printing a bit more of it.

​I’ll start by saying PPS-CF is not a beginner filament. You need a capable printer and a dedicated filament dryer to get these results. This type of filament requires special attention to routing of your PTFE tube, to avoid any sharp bends, it will snap inside. The spool arrived perfectly wound, tangle-free, and vacuum-sealed with fresh desiccant. ​Performance & Settings: This material loves heat. I achieved best results with: ​Hotend: 340°C ​Bed: 110°C ​Chamber: 50°C (Heated) ​The Results: Adhesion was flawless with zero warping. The dimensional accuracy is honestly the best I’ve seen from any engineering-grade carbon fiber blend. The CF fibers do an incredible job of hiding layer lines, leaving a clean, matte surface finish. This stuff is awesome, its metal and the noise it makes when you drop on a counter. If you need high heat deflection for brackets or functional mechanical parts, I highly recommend this.

PP doesn't seem to be the best material, but it worked for my purposes. No printing issues, as long as you use a brim, since it tends to warp and lose adhesion along the build plate.

Finally got my hands on this Polypropylene filament…and I have to say, WOW!! I went for it right after opening it, no drying(the material is not hydroscopic) and wanted to see how it printed right out of the box. Ran a temp tower first, looked great with minimal stringing. Went straight in to a Cali Cat, looked great! Then dove right in and printed a straw cap for our cups. I have to say I am thoroughly impressed! To get it to stick to the bed…I used a generic PP profile in Bambu Studio, added some blue painters tape to the print bed with clear packing tape on top of that. Used a 10mm brim, bed at 60 degrees and nozzle of 230 degrees, and it came out flawless with no adhesion issues! Will definitely buy again! Highly recommended!!

Printed great and held up well to testing. I used PP tape for build late adhesion but plan on getting the proper adhesive going forward. But even with that it came out super clean and is firm yet flexible enough to be extremely durable.

Overall this filament was pretty easy to print, especially considering it’s a higher end engineering filament! The print quality and final finish is gorgeous with that rougher texture that hides the layer lines. For adhesion, make sure you use clear packing tape for PPCF and bed weld for ABSCF. I did fully calibrate the filament in my slicer and dried the filament for over 24 hours. Very strong and lightweight!
