Review: Prints exceptionally! - This is my first experience with TPU and I would say it's gone very well. I've attached a video of the calibration cube I printed with this filament and I've left my print settings down below. It was printed with two perimeters and 15% grid infill and it can be squished in the fingers and will still conform to the pressure. This filament is strong but flexible. TPU is supposed to be very Hygroscopic and I think it's moist from the packaging because it seems to give me a slight bubbly consistency on the surfaces of my prints, so I'm gonna try to dehydrate it and I'll edit this comment to reflect on my experiences. EDIT: I was printing too high a temperature. Often TPU is printed at roughly 235c but I took this down to 210 and it prints a dream. Updating settings below to reflect mine which prints perfectly now! Sanding does scuff the side and makes it a little smoother. Ensure you use a bonding agent (glue stick, hairspray) on the PEI print surface if you're using a prusa as TPU can adhere to PEI far too well and you'll damage your bed. However, it prints just fine. It's very firm, can withstand a lot of pressure and the layers bond perfectly so it when it flexes they don't split. It flexes a lot! It's impressive! PrusaSlicer already has a preset for this filament which is great! Here's my print settings, for the Prusa Mini+ Speed: 15mm/s for everything but 40mm/s for bridging Layer height: First 0.3mm, the rest 0.2mm (you want less squish on that first layer) Perimeters: 2 Infill: 15%, grid pattern Extrusion multiplier: 1.15 (helps those layers bond well) Max volumetric speed: 1.8 Filament type: FLEX Extruder temp: 210c Bed temp: 50c Fan speed: 80%, 100% for bridges Seam alignment: nearest (probably reduces stringing) Top layers: 5 Bottom layers: 4 Retraction: completely disabled Avoid Crossing Perimeters: enabled (important for massively reducing stringing) Overall, I'm happy with this filament! It even prints well on a bowden system which is great! Gave a 4 because of the bubbly surfaces, hopefully it can be resolved! EDIT: Gave a 5 now because I can print perfectly smooth models with this stuff. It's amazing! Hope this helps... Happy printing :) x
Review: Easy to Print with. - First time trying to print with TPU very easy and excellent results first time, the picture doesn't do it justice and there has been NO post processing what you see is how it came off the printer. Printed on a CR10s with a BMG extruder and a E3D V6 all metal hotend set up as a direct drive, I used the following settings in Cura... Initial Layer Hight - 0.32 mm Layer Hight - 0.2 mm Infill - 20% Nozzle Temp - 215c Bet Temp - 50c All Flow set to 110% except Infill and Initial Layer which I left at 100% Print Speed - 40 mm/s Wall Speed - 20 mm/s Top/Bottom Speed - 20 mm/s Initial Layer Speed -15 mm/s Retraction Disabled Combing Mode - Not In Skin (helps to avoid stringing) I used 3DLac spray to help with adhesion and removal. A little expensive at normal price but even then worth it if you need a flexible print for a trial I bought it on sale so well worth it, would definitely recommend.

## Features

- Approximately 250 grams, feet of filament on a spool with a case so it's not flopping all over the place. Splash Spools store easily in a desk drawer, stacked space or even hang on a wall. Be sure you are ordering the correct diameter for your printer. This product is only available in 1.75mm.
- Specially formulated plastic with increased amount of flexibility, with rigid structure. Recommended for printing objects, which will be impacted more than normal ones.
- SAINSMART filament is 100% TPU. TPU is essentially polyurethane, it belongs to the TPE class of thermoplastics. Recommended for printing objects, which will be impacted more than normal ones.
- Flexible Filament does not feed well on all 3D printers. Please check your printer specifications before ordering. Only available in 1.75mm diameter.
- It's better to work on direct drive extruders. Please print slowly and read the tips if you are bowden.

Very good quality filament, works really well after slowing print speed and disable retraction.
