Increasing build-plate temp. to 130-140oC

[Jamesbritton3 0]

Hi Everyone, 

 

I have an Ultimaker Original.

 

I want to raise the build-plate temperature to around 130 degrees Celsius for a specific material.

The specs say that the temperature range is 70-100oC.

 

Have anyone raised the temperature higher and if so, how?

 

Thanks,

 

James

Hi!

 

The max temp you can set is actually 135°C I think - on the original firmware.

But that doesn't mean that the bed can reach 135°C because it is just too weak.

I think under normal conditions it will be about 110-120°C (after a long waiting time..).

And only if you turn off the fans! If they are on the temp will drop dramatically.

 

Things you can do to reach 130°C-140°C:

1. insulate the bed somehow (put insulation material between the bed and the aluminium plate) - this will probably only give you 5-10°C higher temps on your bed

2. raise the environment temp - this helps a lot (I built an heated chamber for my UMO+ that can reach 90°C - and I think I could easily reach like 150+°C on my bed). And I think nothing gets harmed when the temp is that high but I am not sure

3. buy a new (230V) heated bed - probably the best idea. There are some beds that can reach 200°C. Then you also need another power supply but all in all not that expensive

 

I hope this helps you,

Chris

Most consumer electronic components are designed for a long-term maximum operating temperature that you can still touch, although barely, about 60°C. This is heat due to power dissipation in an environment of 25°C. Especially electrolytic capacitors, diodes, small transistors, chips, LEDs,... are sensitive. Power transistors and -amplifiers, and resistors, can usually withstand a lot more. Above that temperature the components usually don't die immediately, but their life shortens a lot. And power drivers need to be able to release their heat. I don't know about Ultimaker electronics, but I don't think they use military grade or dedicated high-temp electronics? So I don't think putting the whole printer in a heated cabinet is a good idea. I would suggest: heat the bed and print chamber, but keep all the rest cool: electronics, displays, drivers, power supplies...

I did not just put my printer into a cabinet but I totally modified my UMO so now it has a heated chamber. I have a water cooling and much more to make this work. 

if you are interested..
