DESCRIPTION

SainSmart TPU filament is characterized by its high strength and flexibility, resembling a hybrid of plastic and rubber.

95A TPU has high abrasion resistance and low compression compared to rubber parts, especially at higher infill.

In comparison with common filaments like PLA and ABS, TPU must be run much slower.

SPECIFICATION

• Material: Rep-Flex TPU - Vacuum sealed with desiccant
• Shore Hardness: 95A
• Weight: 1 KG (approximately 2.20 lb) spool weight total, net weight 0.8 KG
• Diameter: 1.75mm (+/- 0.05mm)
• Recommended extruder temperature: 195 - 230°C
• Recommended platform temperature: 40 - 60°C

PRINTING TIPS

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

• Print slow at 15-30 mm/s printing speed.
• First layer settings: height 100%, width 150%, speed 50% (e.g.).
• Retraction disabled to reduce messy stringing or oozing.
• Increase multiplier (optional); setting to 1.1 helps the filament bond well.
• Cooling fan on after the first layer.

If you are having problems printing with soft filaments, slow the print down; running at 20 mm/s will work perfectly.

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

Feed the filament directly to the extruder, not through the feeder tube, to reduce drag on the filament and prevent slippage in the gear.
