YOUSU PP Filament 1.75mm for Industrial Part, High Temperature Applications, Mechanical Compon, 1kg (2.2lbs) Polypropylene 3D Printer Filament, 5 Pcs Build Sheet Included,White

This filament prints very well for polypropylene. The filament size is consistent, it extrudes easier, and it seems to adhere better than your usual roll of PP. They even provide a handful of sheets that you can stick to your build plate, which is likely a film also made from polypropylene. And no, you don't have to worry about the adhesive having a death grip or leaving behind tacky residue. I just want to make it's clear that this filament is pretty high quality, but there are some things that you should know about it first. Since you are also likely looking specifically for polypropylene, which is a pretty uncommon printer filament, I would assume you are also chasing after its unique resilient properties. Let me quell some of your concern and give you the details so you know what you're buying. Full transparency: I bought this roll of filament because my usual source of polypropylene was out of stock. Getting your hands on 1.75mm PP filament right now seems to leave you with very few choices. Usually all you can find is expensive international options or expensive gimmicky rolls with some sort of color or filler like carbon fiber. The bright white color of this polypropylene is a red flag since it is usually quite translucent. The full 1kg roll is also a concern since polypropylene is usually only sold in 0.7kg quantities. This has to do with the density of polypropylene being much lighter than PLA or ABS. After doing a print, I did indeed confirm this filament is denser than pure, raw polypropylene by about 13%, something that was not made clear in the listing at the time. Let me be clear, this is still lighter than PLA. I talked with the manufacturers about this since the part I printed was obviously heavier than a part printed with pure PP, and they were very helpful and patient with me. I was informed that, yes, this polypropylene is heavier than pure PP because of some of the additives. These additives are used to help the filament in all the ways I mentioned before, namely extrusion and bed adhesion. According to what they told me, this filament still retains the toughness, chemical resistance, and similar rigidity to pure polypropylene. I can attest that yes, the toughness and rigidity is very similar, but I am unsure about the chemical resistance. And even though they, and many other PP distributors say these material is food safe, I wouldn't EVER drink or eat off of a mystery plastic unless it's been through some kind of legitimate certification process, which I don't think exists for printer filament. One last note, this polypropylene also has the same layer adhesion just like pure PP, you just need to make sure you're printing at a high enough temperature to get those layers to really stick together. If you've never printed with PP before, the layer adhesion strength is amazing. It's almost like the part is completely homogeneous. Layer separation is quite difficult if not impossible to even forcefully induce in some cases. It'll be much stronger than PLA or ABS in this way. Maybe better than any other readily made printer filament. So in short, here's the pros and cons. Pros: -Actually consistent filament diameter. A lot of manufacturers say this but don't deliver. These rolls are actually good. -Slightly better bed adhesion than raw polypropylene (use their film or PP packing tape). -Better extrusion characteristics (didn't need to adjust or crank flow rate as much for a good print). -Comes with bed adhesion films so you don't have to hunt down tape or buy expensive adhesive. Neutral: -Denser than raw PP by 13~%, but take that number with a small grain of salt. -Opaque white color -Unknown additives that result in the above property changes. -Sweet print smell. Cons: -No obvious cons. Any of the neutral points could be considered cons, and for me, the extra density of the filament WAS a con, but it completely depends on what you need the filament for. If you do your due diligence and are looking at this review or others, you'll know more or less what you're getting, and how different this stuff will be from pure polypropylene.

I was able to print with this filament using the supplied PP film. It comes with 5 pcs PP sticky sheets (I think they are 150*150 mm), which from my experience each one is only good for a single use since the print fuses with it and you essentially tear it when removing the print with part of it remaining on the print. Printing is feasible, I was able to print a 100mm long part. However, warpage is significant, and the only thing helping with it is the part literally fusing with the PP sheet, but the edges still get pulled a bit, the bottom of the print is not flat. And should be noted that I was printing on an enclosed printer with 45°C chamber temperature.

This appears not to be a pure PP filament, other sources claim it is slightly denser than pure PP and has additives to make it easier to print... Well, whatever they are, they work! This filament has fairly typical PP bed adhesion issues, and it can, and will warp in certain situations, but it's remarkably easy to print and manage. Layer adhesion is incredibly strong, just like pure PP, and it produces a semi-flexible print, but it strings and ozzes very little and flows extremely well, even at moderately high speeds. This seems like a quality filament if you need the resilience and chemical resistance of PP, just a bit easier to print. Don't forget to check the bottom of the box for the included PP adhesion stickers. I use Magigoo on a textured PEI bed, so I haven't tried the stickers, but if you have a smooth bed it's nice that they include them.

I tried this on an AnkerMake M5. I used the film that is supposed to attach to the plate, but it won't stick once the print starts. According to Yousu, I need to use these settings: Hot End Temperature: 225 - 235 Bed Temp: 85 Printing Speed: 30mm/s Nozzle: 0.04 Bed Surface: Clear Build Film On my first test print, the build film warped and my nozzle burned through it. I adjusted the temp down thinking that my bed might be hotter than others. After multiple attempts going all the way down to 50, it won't stick. The film warps and the nozzle burns through and tears when I try to pull the failed parts off the film. I tried using tape and the tape didn't warp, but when I checked the print, the PP had curved and warped. The first pic is what I got when I stopped printing. That is pure garbage. After multiple attempts at various settings, I have given up. This stuff is useless and a giant waste of time. Do not buy it.

I don't like leaving negative reviews, but I am convinced this filament has "chunks" that regularly clog your hot end. PP is hard enough to print as is. Dealing with random clogs that cannot be mitigated through any setting changes (at least on a Bambu X1C w/ a 0.4mm nozzle) is a deal breaker. That said, it seems people have luck printing this with a 0.6mm.nozzle - again suggesting that "chunks" are an issue. In the end, I bought some Verbatim Natural PP and found it prints beautifully. No clogs, crystal clear, and just as easy to print as this stuff. I recommend going with Verbatim and never looking back.

I have edited my review to discuss a serious issue with the filament and grit that is present in it that causes the nozzle to clog. My initial experience was very good but it changed. My initial review is at the bottom. I’m very familiar with PP filament in general and have a fair bit of experience using it. This filament worked well initially but clogged my nozzle at random intervals. I initially tried to clear the blockage using an thin wire tool and the tool was also blocked by the foreign object. I was able to dislodge it to the point that I could hand press the filament through the hot nozzle for a few seconds before the foreign object would block the nozzle again. I decided to trap the object and do a cold pull. I then used a piece of white PLA and the thin steel tool to clear the nozzle of the black Polypropylene until only white PLA was flowing through. Then I reduced the nozzle temperature to 100 C and pulled the solidified PLA out. The cold pull worked perfectly and I got everything out of the nozzle in one piece. And as expected I could see a small black object embedded in the white PLA right where the nozzle narrows down. I’ve never had this happen before with another filament and I thought that perhaps it was something that fell into the extruder and I didn’t want to blame the manufacturer right away. So I thoroughly cleaned my 3D printer and carefully unwound about 10m(30ft) of filament off the roll and wiped the filament down with a white paper towel soaked in isopropyl alcohol. The paper towel did show some black particulate but not of the sort that could clog a nozzle I think it was mostly just plastic dust so that’s ok. I then restarted the print. And after extruding about 16-18 grams of filament, the nozzle was clogged again with a foreign object. I have experienced 3 cloggs in less than 30 grams of filament being extruded from a 0.3mm nozzle( I know it’s a smaller than average nozzle but since I could see the foreign objects were bigger than that, I’m sure an 0.4mm nozzle would also clog). So unfortunately for me, this filament is not usable with regular sized nozzles, I will keep it to try with a 0.8mm nozzle someday as I think that will likely let the contaminants pass through but who knows? Too bad, I did like it. first review “I was initially hesitant to try a different brand of polypropylene filament vs the Fillamentum 2320 PP that I usually use. But this filament prints better than that one while using the same settings. I did find that this brand was less strong, a bit softer and and had a greater elongation than Fillamentum 2320. But for me the easier printing (easier to stick it to itself, and more fluid at 242 degrees C) was more of a benefit.

As with any other PP filament, getting it to stick to a bed not specifically designed for PP is incredibly difficult. Product itself is solid though, no jamming or anything.

Polypropylene PP Filament 1.75mm, hailed as a high-quality material for 3D printing enthusiasts, seemed promising upon initial inspection. Arriving as described, the filament was vacuum sealed with a desiccant inside, to aid with keeping it free from moisture and in optimal condition for use. Despite these positive initial impressions, my experience with the filament has driven me to award it only one star. My 3D printer is the Neo Kobra 2, a reliable machine that typically delivers excellent results with various materials. However, when I attempted to print a keychain using this Filament, I encountered significant issues that hindered the printing process. The first few layers of the print were ok, seemed to be able to produce high-quality output. However, as the print progressed and more material accumulated on the printing bed, the filament started to warp. This warping was not just a minor inconvenience; it caused substantial distortion in the print, ultimately leading to the print detaching itself from the bed. This recurring issue rendered the filament practically unusable for my project. In an effort to resolve this problem, I experimented with various adjustments. Setting the bed to higher temperatures, which is a common solution for improving adhesion and reducing warping in many filaments, did not yield the desired results. I even placed the printer in a temperature-controlled environment, hoping that stabilizing the ambient temperature would mitigate the warping. Unfortunately, these measures proved ineffective, and the warping persisted. The frustration of watching a promising print fail repeatedly overshadowed the initial appeal of the Polypropylene PP Filament 1.75mm. While the material itself appeared to be of good quality, the practical difficulties I faced made it clear that this filament was not suitable for my needs. The warping issue, in particular, highlighted a significant drawback that could be a dealbreaker for many users seeking reliable and consistent printing results. In conclusion, while the Polypropylene PP Filament 1.75mm arrives in excellent condition and appears to be a high-quality material, my experience has been marred by persistent warping issues that compromise the overall printing process. For those considering this filament, it is worth noting that despite its promising attributes, it may present significant challenges in achieving successful prints. As such, I would advise potential users to approach this filament with caution and be prepared for potential difficulties in achieving the desired results.
