## Overview

The SainSmart 101-90-161 Blue Flexible TPU 3D Printing Filament is a high-quality 1.75 mm filament weighing 0.8 kg, designed for creating strong and flexible parts.

## Description

Overview: SainSmart TPU filament is renowned for its high strength and flexibility. With the design freedom of 3D printing, SainSmart filament is the key to bringing your project, whether it be a weekend hobby or prototyping for a Fortune 500 company, from the sketchpad to reality. Each spool of SainSmart TPU filament comes with 0.8 kg/1.76 lb of material. This filament is drawn out to a diameter of 1.75 mm with a dimensional accuracy of +/- 0.05 mm, making it the perfect choice for most printers on the market. Specification: Diameter: 1.75 mm Material: Flexible TPU Net Weight: 0.8 kg Shore Hardness: 95 A Recommended Printer Settings Print Nozzle: 0.4 – 0.8 mm Extruder Temperature: 195 – 230°C Print Bed Temperature: 40 – 60°C Cooling Fan: On Printing Tips For Bowden Drive Printers Print Slower: 15 – 30 m/s First Layer Settings: 100% Height. 150% Width, 50% Speed Disable Retraction: Should reduce oozing and stringing Cooling Fan: On after first layer Increase Multiplier: 1.1, should increase bonding  Do not over extrude filament when loading. As soon as the filament start protruding from the nozzle, stop. Loading any faster will cause the filament to get caught in extruder gear.  Feed the filament directly to the extruder, and not through the feeder tube. This reduces back tension in the filament as well as drag, ensuring proper feeding. What’s in The Package 1x SainSmart TPU Flexible Filament 1.75mm 0.8kg vacuum sealed w/ desiccant

## Features

    Prints great with a bowden extruder (slowly)
  

*by S***P on Reviewed in the United States on May 4, 2017*

This stuff's pretty awesome. It prints well at 10mm/s through my (long) bowden extruder. Just make sure the area after the filament leaves the extruder gear is closely constrained so there's no gap for the flexy filament to buckle and push out when it's trying to feed.- 10mm/s- 220C- retraction disabled- cooling fan on after first layerI got the TPU in "clear", but it prints kinda milky. Colorwise, it almost looks foamy, but the surfaces are nice and smooth. In my experience it doesn't bridge very well and it can string, but neither is terrible. I recommend picking up some flush cutters to trim the strings; the prints are very durable, and so are the strings! You probably won't be able to cleanly pull them off and sometimes even a razor is tricky to use for cleanup.Layer adhesion is fantastic. Thin-walled prints stretch and squish pretty easily and return to their shape. I haven't seen any delamination yet.A single layer printed on the bed is floppy and droopy like wet paper. Two or three layers are about the stiffness of thick paper. Half a centimeter thick with 25% infill and it's a little less stiff than a rubber spatula. Add thickness and infill and the print starts to feel like a rubber doorstop.TPU is great for printing parts that need to friction-fit together since you don't have to worry about getting tolerances really close. Things will just flex into place.

    Surprised!
  

*by K***S on Reviewed in the United States on September 21, 2015*

Sainsmart 3d printer hardware and electronics have often been a disappointment in the past. So I really hesitating trying this filament, especially considering it is roughly half the price of Ninja Flex (get what you pay for...). Surprise! This stuff is incredibly good!!Using an E3D hybrid with a PTFE liner through the aluminum fin body and another PTFE liner through the stainless steel barrel, this produced the best flex prints I've ever done (NinjaFlex, FilaFlex, Flex PLA). Good layer adhesion, good bed adhesion (Aquanet on 50C glass). It's printed object is a little less elastic (stretchy) than others. I could not get reliable prints using an all metal barrel, but have printed a dozen objects with no feed problems using a PTFE lined barrel. Sainsmart TPU on the roll is very flexible, meaning there can be no gap between the extruder drive gear/idler and the channel the filament is being pushed into - this stuff is a bit more exacting than other flexs for that.225C produced a very glossy finish. 215C produced a jam..4 nozzle, .2 layer height30mm/sec.Slic3r Default Extrusion Width setting of 125%.Slic3r retraction of 1.5mm with a Lift Z on retraction of 1mm with a Retract on all non-print moves. The Lift Z setting takes a split second, which gives the heat chamber pressure time to react to the retraction, eliminating the hysteresis dribble that is so common with flexible filaments.If I can think of other flexible things I want in other colors, Sainsmart TPU will be first choice based on the performance of their black.

    Dang good stuff!
  

*by M***A on Reviewed in the United States on February 19, 2018*

I ordered a roll of this TPU in Crystal Orange on Feb 13 2018.  As it would turn out I ran out the last of it on Feb 13 2022.  I bought it for the color, having seen some amazing prints others had done in this color.  I also bought a roll of the crystal blue.  I've used them randomly and for about every kind of project.  This TPU prints as easily as anything you will ever print with.  Extrudes smoothly and beautifully.  It almost looks like its just falling out of the nozzle.  It is VERY strong.  Stronger than any TPE and as strong as any TPU I've used.  So its great for protective thingys, but also nice to look at.  The color is very dense and vivid yet is nonetheless very translucent.  The color really pops under light, and looks even more amazing when its backlit.  The filament itself seemed very consistent and never seemed to absorb much moisture nor did it discolor over time.  And after exactly 4 years I can tell you that the last foot of the roll looked and extruded just as good as the first foot.  So buy with confidence.  This is some of the best stuff out there.
