Verbatim Polypropylene 3D Filament 1.75mm 0.5kg Reel - Natural

After reading about 3D printing with Polypropylene (PP), I had low expectations. I was impressed how well this PP worked on my first try. I'm not finished yet, but encouraging. So far, this seems like really good stuff. You need a heated bed, good adhesion to the bed, I lowered the travel speed a bit and turned jerk down, filament cooling on. I also had an extruder issue. PP is soft. The extruder ground down the soft filament even though I thought I had reasonable clearance with the hot tip. Once I had reasonable flow, I retreaded the filament so the gear could get a good bite and push filament into the hotend. Then everything worked! I watch the spool and look for it to turn. If it doesn't, nothing is flowing. Your mileage may vary.

this stuff is very different to most other filaments. It is much lighter than PLA and warps more than ABS if you arent careful. I am running some proto-type parts for a guy and it works but you have to run it slow. The biggest issue is that it does not stick to the build plate. Polyprop only sticks to itself, i was using a PEI build plate, glue, painters tape, Kapton tape, etc. and nothing worked. The only thing this sticks to is cheap clear shipping tape. Once you figure that out it sticks no problem. I was running at 235C, 85C on the bed, 35mm/s 20mm/s on walls and have had good results. With this stuff hotter is better, it will not bond well to itself under 230. dont use a cooling fan if you can help it, it warps instantly.

Pp filament ist sehr gut leicht flexibel und doch ein Lebensmittel echtes filament.Die Haftung auf meinen druckbett war nicht so gut und das filament neigt sehr zu warping löst sich auf einmal vom druckbett. Abhilfe habe ich mit einen holzleim Wasser Gemisch auf mein druckbett gestrichen. Und einen geschlossen bauraum für meinen 3d drucker!

One the lowest density filaments at 0.89 g/cm3 (it floats really well!) with good fatigue resistance for living hinges. Final part operating temp range: -15C to 130C approx.So far I've only printed smallish items with 0.25mm nozzle (0.3mm line width, 0.16 layer (0.2 1st layer) 225C, 30mm/s), but am really pleased with how they've turned out.With a glass print surface it's been easy to put down some 3M clear packing tape (using some that's 75mm width), leaving a bit over the edge of the bed to help peeling it off.Not overly squishing the first layer gives multiple uses out of the tape; print closer and parts adhere really well so it tears up on removal. I haven't needed any heated bed for good adhesion.*Some things to consider*Virgin PP degrades in UV light, but stablisers can be added during its manufacture. No info on that for this filament - *hopefully* Verbatim would say if it were a major issue? I like that it doesn't absorb water.Part cleanup: It can't easily be painted, glued, pared or sanded (just sort of scuffs up) so surface finish is down to tuning your printer/slicer for the model. I've found small, sharp, curved cuticle scissors (good ones here: https://www.amazon.co.uk/Rostfreie-Scheren-im-Etui-1911-1914/dp/B07262ZG77/) and a heat tool useful for the minor things like zits/stringing.For small, thin parts it needs a minimum layer time or a silicone sock to prevent deformation from the radiant nozzle heat. Handles overhangs well with wider / flatter layers like PETG.Not really an every-day filament, but some good potential design uses for it - I will definitely keep some around. More colours would be nice, but presumably that's just down to the market. The Amazon offer of £22.98 is good and, because it's low density, 500g of filament was longer I expected at 233m. Verbatim gives detalied material info on their site (have included a screen) and the fact it's made by Mitsubishi Chem Co is impressive - says 'Made in Japan' on the box.As it doesn't appear to need a heated bed with PP tape I currently prefer this to PETG, which was my previous favourite for making durable stuff without a nasty VOC odour. It is similar to print with, if not a bit easier - would be interesting to know if it has similar low UFP emissions.

Gut verpackt, ordentlich aufgerollt, lässt sich bei angegebenen Temperaturen gut drucken. sehr maßhaltig. Neigt aber leicht zu warping und hält nicht gut auf super plate.

Gleich vorweg: Mag sein, dass jemand mit anderem Setup gut mit dem Filament zurecht kommt. Und mir ist auch bewusst, dass PP im Vergleich zu PLA eine andere Liga ist. Bei mir jedenfalls kam es trotz mehrerer Versuche basierend auf den vom Hersteller empfohlenen Einstellungen und weiterer für andere PP-Filamente zu massivem Verzug und Ablösung vom Bett. Der Druck war nicht zu gebrauchen. Im Wesentlichen habe ich es mit Düse 220°C, Bett 80 und 120°C und 30 mm/s Geschwindigkeit getestet.Daher "neutrale" 3 Punkte.Falls jemand bessere Ergebnisse erzielt hat, freue ich mich über Tipps und Empfehlungen.

I struggled at first getting this to print due to warping and bed adhesion, however, simply using ordinary clear parcel tape on the bed totally solved this. I always print on a raft as it both prevents warping, and makes the part easy to remove. I also disable print cooling as this seems to help reduce warping.This is similar to work with as Nylon, yet is quite a bit softer. Good advantage is it is resistant to organic solvents.Using Dremel 3D45Can print at 60mm/s for most stuff, slow to 30mm/s for fine detailBedTemp: 50CExtruder Temp: 225C
