printing spare parts with support  

Re: printing spare parts with support

None of i3 printed parts need to be printed with supports, AFAIK. I successfully printed all parts except LCD cover (I'm using different type of display) on 0.2mm layer, 3 perimeters, 3 bottoms, 4 tops, 25% infill. No supports, no brim, no raft.

Re: printing spare parts with support

hi community,
acutally i'm printing several x-axis carriage / extruder parts with bdp (which has with 110°C a higher vicat softing temperature than usual abs (94°C) or petg (75°C)).

from my point of view, these parts need to be printed with support.

😕 ❓
but now i'm a little bit concerned about the support that is generated inside the zip-tie channels. will i ever be able to remove the support out of the channel ?
or need this part to be printed only with support from the printing surface ?

I'm very interested in the BDP filament.
Have you printed things with it?
Did you test the temp-stability?

110c would mean it doesn't soften in boiling water, which would be great, if true. could you maybe throw a print in hot water and test that?

Maybe add a few words on general printability?

@david: thanks for that info ❗
@mavu: you made me curious and i checked it out 😉
the printed bdp part holds it's shape in boiling water without any problems. but you can deform it when you apply some force at it.

you can see that i pushed down the structure in the middle with a tool (7mm nut with shaft), and it gave way a bit. furthermore the front weaved a little.

it's definitely stronger than pla and holds it's shape perfect at 100°C, but it loosens it's strength.
so i wouldn't risk to print a tea pot out of it

about the printability:
easy !
just add 10°C to your pla nozzle temperature. heatbed @ around 65°. no visible signs of warping. cooling fan as usual (after 1st layer). print speed is very good ! i'm (still) printing my extruder/x-carriage spare parts @60mm/s but there are faster speeds possible.

This sounds interesting - links to suppliers? (Best would be in the US...)

just search for "extrudr" & "BDP"... but the stuff is quite expensive (got it for x-mas).

Thank you for testing!

One more question before I push the button that makes my wife angry:
is it like PETG in that it requires gluestick on the bed so it doesn't stick too well?
Or in other words, does it come off the bed easily when its cooled down?

Also, I'm pretty sure this is the exact part I am considering buying High Temp material for 😛
Does it work better than the stock cooling fan duct?

no, quite the contrary: it's really a pita to get it off the printbed, even when its cooled down ❗

Re: printing spare parts with support

Does talc work at reducing the sticktion?!

might be, but then you risk to loose the required adhesion (which will end up in warping or the print popping off the bed).
would be a tricky walk on the rope to figure out the right amount...

Not sure if it applies to BDP, but I print PETG and flexibles with gluestick, and that sticks and comes off reasonably well.
