Specific kiln ramp up times for candling, evaporating, etc...

[Chris Kohlhepp]

I have a question, I am trying to make some reasonably small parts, like half an inch by an inch. Consequently there will be only small amounts of magic powder to candle and small amounts of PLA to evaporate. Do I still need the long ramp up times? Or do you have other recommendations?

Best Regards

You need to follow the firing schedule in the help section of the website it is required to fire successfully. Sintering time is the only thing that is adjusted by the size of the objects and the time of 45 minutes is required for small parts, large parts can require 2 or 3 hours sintering. You need at least a half inch of magic black powder on all sides to protect your print while firing, Bmp does many other things to there is a post here that explains quite clearly, thanks for your question.

Hello Jeremy, 

Thanks for getting back to me. I have another question. Will an cleaned up can, as in baked beans can, do as a steel container for firing? Or do I need something more substantial? Also your Fahrenheit temperatures come out to about 980 Celsius. Copper melts at just over 1000 and is purported to start sintering at around 700 Celsius, which raises the question as to what happens at lower temperatures? Can you elaborate?

Thanks again

a baked beans can is made from aluminum which would melt way before the copper sintering temp you have to use steel which has a higher melting temp than copper, I use Fahrenheit so copper sintering temp is 1800 it melts at 2000 not sure hat you mean by what happens at lower temps, if you read the sintering schedule under the help section of the website it does explain each step or did you mean something else.
