ColorFabb HT

Recommended Posts

Last days tried to print with this high temperature filaments as i need something to can handle my cars temperature without melting. Unfortunatlelly the prints from this material comes out very sensitive and break very easy. Maybe the problem is i use 260C and maybe need more (280c). Does anyone know away to print right with this material or a way to use more than 260 on my ultimaker 2 extended + ?

I print with recomended from colorfabb settings (except temperature use 260 and they need 250-280)

Thank you.

I print with HT on 265C, but I have used 260C and it wasn't more brittle – but had to print at a slightly slower speed.

To make really tough parts I increase the flow, it really benefits the HT. However increased flow will also sometimes give excess material, so be careful with the adjustments especially if your objects should look good. Also like XT and nGen, material sticking to the nozzle becomes brown and makes ugly spots on light colors. For even tougher parts increasing to 100% infill makes them almost indestructable, and thicker perimeters are also helping.

Even if you print only at 260C I think having the extra i2k beneath the teflon is a must, just remember that for the 2+ models you would need either a spring or a custom part as the part above the teflon is only one size and will not fit with the stock teflon and i2k at the same time.

You might want to look into I2K (3dsolex) and tinkergnome firmware. Google time!

 

@Tinkergnome firmware does not allow to set the maximum temperature. But you can edit the firmware source according to your needs. I extended the range to 290°C, which leaves my TF2K equipped hotend on the safe side.

Some results of a 270°C-250°C overhang test with HT:

I also did a test 280°C-260°C but except more stringing there is no difference. I used 280°C for the first layer and 15% fans.

Bed temperature was at 105°C, which resulted in an adhesion loss on the first print, so I used PVA glue water mix which made it stuck - well - like glued.
