Premium 3D Printer Filament Flexible 1.75MM 1kg/spool, White
Print flexible, elastic items using this spool of Thermoplastic Elastomer (TPE) 3D Printer Filament from Monoprice!
Thermoplastic Elastomer. or TPE for short, is a flexible, elastic material that is perfect for making a wide variety of items, including toys, custom belts, and other rubber-like items. It has a low tack, low CoF exterior, which allows for smoother feeding through the filament guides.
The recommended extruder temperature for printing is 210 ~ 225°C (410 ~ 437°F) and prints best with a platform temperature between 20 ~ 50°C (68 ~ 122°F) and with a print speed of 30mm/second.
This 1 kg spool features a thickness of 1.75mm ±0.10mm, with a roundness variation of only 0.05mm. It has a nominal processing temperature of 230° C (446°F). Thickness and roundness factors are laser measured at the factory to ensure accuracy over the entire length of the filament.
- Reel Diameter: 195mm (7.68")
- Hub Diameter: 95mm (3.74")
- Spindle Diameter: 38mm (1.50")
- Reel Width: 80mm (3.15")
I have attached a Youtube video of a segment of the spool that I cut off, as you can see my calipers measured 1.51mm - with pressure that dips all the way down to 1.3mm which is simply too thin for any bearing based extruder. (spring tensioned might be able to use it still)
PROS: Good price when compared to Ninjaflex.
CONS: I would have the filament stop feeding, with my idler turning but the filament not moving. My extruder can handle fluctuations in diameter, but not quite to the degree of this filament. I pulled out my calipers and at some points it dipped all the way down to 1.5mm. With it being flexible filament if I then compressed it at all (and generally filament does get compressed into the gear in order to be driven through your extruder) it dipped even lower than that which my extruder just couldn't handle.
If I had to guess, I think it is a problem with the material being too soft. I have ninjaflex which seems to be moderately stiffer. It pulls into the extruder fine compared to the Monoprice material. I have cleaned out the extruder head multiple times but still it fails to load properly most of the time. If I do get to load it draws very slowly, and once I'll start a print its as if nothing will even come out. I've tried multiple speeds, temperatures, etc with no luck. I'll keep trying to find any parameters that work, but until then I'd avoid this filament.
PROS: Good price for 1Kg spool
CONS: Won't get a consistent print. Won't load properly compared to ABS or PLA.
3D printing is an adventure. and this is one of the more challenging filaments. I sliced my print with incrementing temperatures from 215 to 260 C in 5 degree increments until I got good adhesion. I found that the lower temperatures would be pulled off the bed at the next pass of the extruder nozzle and loop around the extruder. Eventually enough built up that the print failed.
PROS: Good Material
CONS: Suggested printing temps didn't work
CONS: Too soft/Binds and clogs easily
