good morning youtube so it looks like we had a successful print here this ran overnight took
about 14 hours of printing and that's in abs plastic really large part oh it looks like it
did pull up at the back there a little bit let's see what it's uh see if we can get it off here
okay got it broken loose it was really stuck down pretty well the back corner
over here lifted a little bit that's one of the support pieces there if you can see that
throw some light on there so that corner lifted up but it printed okay it's kind of the support
material around the outside that all gets cut away and the main part looks like it worked pretty well
yeah i think that worked out okay it didn't have any delamination on the sides that looks all solid
good morning youtube see that's my third go this was one i printed yesterday i had to abort it
you can see it was pulling up that corner pulled up that one pulled up and it was getting pretty
badly warped so i made some changes to the setup i think the main thing i did i'd put
the abs glue down on the build plate but i also sprayed some hairspray over the top
so i think the hairspray let go so this time i did just plain abs juice or glue
and no hairspray on top the other thing i did on this one is i turned off the brim as you can see
there's no uh brim in there and then let's see i also tried increasing the print speed on this one
to 60 millimeters per second the first one and this one i did at 50 millimeters a second
otherwise i left everything unchanged and i think this one has ran overnight i think that looks
perfect everything's stuck down that's a big piece of abs and there's no warping at all i mean
that is just rock solid all four corners are stuck down and let's see if we can uh pop it out of here
but yeah look at that just that is just perfectly straight
and most of the brim actually stuck to the build plate i'm still getting a little bit of uh warping
up in here although this is this isn't a critical area on the part but you can see that's a little
bit the interiors a little bit warped yeah good morning youtube so it had another print here
and i think this one worked worked quite well i popped this off earlier this morning went
overnight here let me show you this one came out i think as good as you can expect and see i had
full adhesion all the way on all the sides you can see the shine reflection of the lights there going
across pretty much every surface that was touching the build plate and so this one what i did
different is i oriented it across the printer so it was kind of a more uniform temperature profile
rather than having the back i think was getting a little bit too hot i also left the front cover as
you saw it when i started the video so there was a little bit of ventilation and then the
what i did i used the cura plug-in called very at z which is a little plug-in you can
enable and then you tell it at a certain print height or z value you can change a parameter
so what i did was i set it at two millimeters i changed the bed temperature from 115 down to 100
and that worked i i watched the end of the print finished at 100 degrees c
the beginning was 115 so that plug-in seems to work so that i think is my magic uh recipe for
printing abs that was the other thing i have been doing is i use my abs juice so that's with
some red filament in there so just a very light pink color and then i put three coats of that
abs slurry on there drawing in between and that seems to give me enough adhesion to
get going and then the high temperature definitely the high temperature helps
at the start and then lowering the temperature afterwards seems to prevent the warping so
if you like these sorts of videos i'll probably be doing more 3d printing videos so you can check
out i'll put a link to my playlist up in the upper right corner you can also subscribe to the
channel with the link in the lower right corner any comments or suggestions you can put that
in the comments section below the video description and as always thanks for watching you
