Polycarbonate part

Post by amd-tec » Fri Apr 26, 2013 11:56 am

Just tested to print with polycarbonate material (from Ultimachine).
Printed with 0.4 layer, fast, no fan blowing
Tuff material, need to find right settings (and nozzle diameter).
Material is hard to get stuck to perfboard.

Hi amd-tec
I checked out the supplier.
I am guessing it prints a very strong model ?????
What extruder temperature did you print it at?
Regards

Hi,

I used ABS setting, so temp was ~260°C. Would be better if temp been a bit higher, but what can you do ;)!
Yes, the part feel very strong. Layer bonding is good.

Thanks,

You can put a resistor in parallel with the Up's thermocouple to raise the temperature. Just as the "Octave switch" puts a resistor in series to lower the temp, a resistor in parallel will lower the resistance, fooling the printer into thinking the temp is lower than it really is.

The thermocouple is about 197 Ohms at 260 deg C, and the resistance curve is about 2.6 Ohms/Deg C. So to raise the temp from 260 to 290 you would add around 3,000 Ohms in parallel.

Thanks Julia, I knew there's a way to go higher temps.
Now the question is how do I do it ;)?
I'm really not familiar with electronic stuffs.
I have worked mostly only with CAD and mechanical things.
If it is as easy as temp switch assembling so I think
I can handle it.

Thanks,
