2020-06-08 - code::dive - cfp

call for papers for code::dive conference has recently started. while i've been on all code::dive editions, i did not gave a talk there since 2017 – very long time. last 2.5 years i was so busy, i barely had time to get any sleep, whatsoever. this year it has changed – i finally started to rest and slow down a bit. you can see this reflected both on the number of blog entries and OSS projects activity. i hope i'll manage to find some time to prepare a talk for this year. i have already a topic selected for well over 3 years now. just need to find some time to actually make a talk out of it. deadline is in 1.5 month from now… let's see…

2020-06-08 - printing BIG

last year i've bought a new printer (will write a review one day – i promise!). details aside, it's printing area is huge! it can print 40x40x45cm objects. this opened a lot of doors (again – topic for a separate blog entry). while obviously you typically do not need to print things THAT big, i did had 80h lasting print this year already. so i wondered – what is the maximum print time?

it obviously is model-dependent, but just to have an overview on a row of magnitude here, i've create the test app, in OpenSCAD:

cube([400,400,450]);

it took some tens of minutes and GBs of RAM to generate gcode out of it. it took even longer to process it with a python script for estimating print times, based on gcode. here are some numbers:

OpenSCAD model processing time – 1s
model STL file size – 2kB
gcode generation with slic3r – about 5 minutes
gcode size – 4GB
print time estimation calculation – about 15 minutes
print time estimation RAM usage – over 95GB (gods bless cloud computing!)
estimated print time – 70 days
filament required – 20kg

checking this out was an amusing experience. when it domes to predicted results – i definitely never want to give a shot in practice. ;)
