hey we're in the garage and we're going to test whether or not two different types
of bed adhesion helpers are going to work on the really big machine let's get to it
so this is the ready shawn you got the graphic ready the 3d platform 300 series workbench pro
i love it when he does that i've had some bed adhesion issues on this machine and i'm trying
to find ways to combat that and i've got two to test out today one this is super 77
this is a multi-purpose adhesive i've got the 3m brand right here and someone in a previous
video mentioned that for larger prints this is what they use on their glass beds
unheated i'm kind of excited about that also we're going to be testing out this this is zilla grip
and this was sent to me during a fan mail friday episode and a lot of people really wanted to find
out if this stuff worked and so we've got zillow grip we've got super 77 and we've got some 3d
benchies ready to go let's just go over exactly the preparations that i did before this so at
first i put on the super 77 and i put on this side of the bed the comment listed holding it away from
the bed four to six inches and spraying and it was going to be clear this wasn't clear i don't know
if there's really anything to be worried about but it's there now actually used a piece of wood
to create that nice line right down the middle not too bad right for the zillow grip i used this
included silicone brush and the instructions that were emailed to me said for pla you don't need
much and you can do a one-to-one mix with acetone i can't find my acetone and i figured we're
dealing with some material that likes to lift so i just did zilla grip on the bed i i hope they
aren't mad at me for that but i used the silicone brush to kind of brush it around the tip flew off
dang it and i found it but you know whatever we got it down on the bed and now for the material
that we're using it's actually proto pasta hi5 blue they had some they couldn't sell in 285 and
so they gave it to me and i was like it's really nice of you to do that and so this is going to be
our test material for this and also in the past i found that high five blue does not want to stick
to this bed with any of the other adhesion helpers i've used because of some additives in it or
something like that there's also a white pla that i couldn't get to stick down the problem is it
would go down in very very thick extrusions like one or two millimeters wide and i think that was
too wide for this material and it just couldn't hold on i just stopped the print because look
lifted lifted lifted that's good there lifted so as far as being a good test i think this
is it as for the model i've sliced up a 3d benchy i've got one that'll print on this
side and i've got one that'll print on this side and so i think i mean we're there it's
ready let's see if these work we're gonna test the super 77 first i'll get the print started
okay i set the print to go we have the nozzle temperature set at 220c
the bed at zero i've got this camera and it's got a nice tight macro lens on it so
i should be able to get nice and close and see how those layers are going down
and then if anything starts lifting we'll get a good good view of it
looks like we're getting a nice squish
i think my nozzle is a little too close to the bed but
we seem to be going okay right now
gotta stop it gotta stop it one of the issues with this machine is the way it levels the head has
two extruders on it and we're using the right one and the right one is heavier which puts as i
was told some downward pressure on the axis which means that you you have to kind of when you lower
it to the bed to level it you have to stack it with something underneath it in order for it to
not be too far down and right now it's too far down so now i gotta fix that and and then we'll
print got that done and we're starting the print again so we should have a
better more accurate proper height between the bed and the nozzle that's what i was
adjusting there and it means that maybe we could actually start the print this
time crash your fingers harder this time come on let's see what happens
that's a little better but what i can do is baby step this
that's there we go that's better well call it even it's looking okay
right that's not bad nice and squished
it's kind of cool i can actually lean on the bed it's not hot
that's pretty good right there
that is a nice thick extrusion yes in fact have a look at those lines right there
that is proper that is proper right there you recognize that
looks like we've got a successful first layer starting to lay down we're going to let this
print and we're going to see what happens test test test test test test test test
i don't understand i'm not sure what to do with my hands listen so it's going and
it's not lifting not one bit like not even one bit so i'm i took the microphone off
and i'm gonna go inside eat dinner i thought it was gonna lift maybe a little bit just a little
bit i would be like oh gosh darn it well we'll try the other one but it's not lifting at all so i'm
gonna go have dinner and i'll check it in a little bit later just had dinner my beautiful wife made
steak mashed potatoes and salad it was wonderful so let's take a look and see how it's doing
oh no that looks like a lift oh no that is lifting like crazy right there look at that
hot dang okay what are we doing over here why i can't it's it's lifting as well
shoot i'm going to go ahead and stop this i don't think we need to fulfill the rest of the
test we've had lifting which i've experienced in the past and so what we're going to do
is reset i'm going to stop this we're going to pull it and then we're going to start the benchy
over there on the zilla grip sound like a deal deal here we go
oh wow yeah if i hold that up look at one side's a little up right over here
shoot and the bow of the boat it's got a little bit of a lift to it see that just a just a
smidge just a smidge my guess is super 77 would probably work a lot better if it wasn't 60 degrees
fahrenheit in the garage my guess if it was a 10 degrees hotter we might have a better stick
that's my guess or maybe if it wasn't high five blue maybe if it was a different pla that didn't
have uh what is it i don't know if it's elastomers or something in there whatever's in there
but anyway we're gonna try the zilla grip now if that's not satisfying i don't know what is
there we go okay it's laying it down and it's laying it down on the zilla grip
looks like our height is good quick test
yep the height is good there we go well we're getting some motion looks like it's laying it down
back there you i'll set up the time-lapse camera what do you say okay seriously it's going down
really really well uh fingers crossed for zilla grip we did we got this far using super 77 the
bottom is i mean look at that the bottom is not too bad it's just it started to lift right here
and it started to lift right here those are kind of pain points i guess when you're doing the
size of extrusion uh the rest of it looks stellar i mean honestly all right fingers
crossed i'm gonna go back in the house i'm gonna go watch a tv show be back in a bit see you then
i'm back and the current print is about the height
of the last one so why don't we take a look because unfortunately there's lifting
there we go yeah yeah look at that it's lifted right there shoot
darn it darn it darn it well we tried let's check the other side just in case okay the
front of the boat looks okay i'm not gonna lie i don't think it's lifted
i'll stop the print and then we'll take a look at it a little more up close
huh came right off look at that so there's the infill structure there the bottom of the
boat looks great it's it's uh it's smooth there's no residual from the zilla grip
it's just that one well here let's take a look so if you look right there it's that corner
darn it i'm kind of sad honestly i was really hoping for a breakthrough here because it's a
big giant machine and it's a lot of fun to use and i like my filament from protopos to the high five
blue but extruding it at a very large extrusion size in this case a 1 to 1.2 millimeter extrusion
width and 0.5 millimeter layer height that is a lot of mass that is heated that then has to
cool down beds not heated though which is kind of interesting and so prints start really fast
and if you look i mean the extrusions they look really really good so i know i've got
something there it's just what's left i've tried bear glass i've tried glue stick i've tried
magikoo i've tried uh dima demofix right yeah dima fix i've tried super 77 i've now tried
zillow grip and i'm running out of options what do i have left if you have any ideas
let me know in the comments because i'd love to try them because once we find something that works
it is it is just it is go time and i love it well thanks for watching if you made
this far you're awesome i look forward to your suggestions and if you can practice kindness
aggressively and i'll see on the other side take care much love and as always high five
