Whether you're new to 3D printing or a seasoned pro, there's nothing better than Sainsmart TPU. This is the same filament we use in RDQ's professional 3D printing center, where we print all of your favorite parts daily with a fleet of Prusa i3 MK3 printers.  Details
  • TPU (Thermoplastic Polyurethane) is a subclass of thermoplastics which prints strong parts that are also flexible.
  • Compatible with all FDM printers on the market that accept 1.75 mm filament. Including Prusa i3, Monoprice MakerSelect, SainSmart xCreality, WanHao & Qidi, and other RepRap printers.
  • With proper settings, TPU is easy to print thanks to excellent bed adhesion and the filament’s tendency to not warp.

PRINTING TIPS:

Recommended for printers with direct drive extruder, 0.4~0.8mm Nozzles.
With bowden extruder you might pay more attention to these tips:

- Print slow 15-30 mm/s Printing speed
- First layer settings. (Height 100% Width 150% speed 50% e.g.)
- Retraction disabled. This would reduce messy, stringing or oozing printing result.
- Increase Multiplier(Optional). set to 1.1 would help the filament bond well. - Cooling fan on after first layer.

If you are having problems printing with soft filaments, firstly, and most importantly, slow the print down, run at 20mm/s will work perfectly.

It is important when loading the filament to allow it to only just start extruding. Once you see the filament coming out the nozzle hit stop. The load feature pushes filament through quicker than a normal print and this can cause it to get caught in the extruder gear.

Also feed the filament direct to the extruder, not through the feeder tube. This reduces the drag on the filament which can cause the gear to slip on the filament.

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.
