Does heatblock size matter? May 18, 2016 02:41AM |
Hey fellow reprapers,
I have a question , for which i did not find useful information.
I learned a lot of stuff by investigating this forum and various other websites.
And i have build my own prusa i3. Mostly really cheap chinese stuff
Maybe a set from china might have been better, ...
but too late >)
And here is my question now:
How does the size of a heatblock affect the print quality / heating time / heat variations ?
I got my E3D clone which is quite good, with a rather "big" heat block. But after ordering some spare heat blocks ( for when i clog one or have to clean it) ,
i received a little tiny one, where the heat cartridge sticks out in the back.
And another one where the screw mechanism is somewhat better, but still a small aluminium block.
I figured the standard cheap stuff from aliexpress and co is around 15*15*10mm in dimensions.
and then there is 20*20*10mm and so on.
Can you say : the bigger the better ? how can i distinguish good from crap ones?
And how can i stop the oozing of filament from the top of the heat block , even though i tightened the nozzle and heatbreak?
Some ideas or experience appreciated.

Oh , thanks for the tipps.
Never thought about , how flush the throat end surfaces might be.
I will check that and sand them down
As price was a major point when i started to build my printer (thight budget as a college student)
i always went the route of taking compromises ( is that the right word in endlish?) and do some tweaks and improvements by myself.
I think i even spent more time tinkering with the machine itself, than actually printing stuff

3d printing has a cost, you either spend money or time.
