Hi,
How do I get printed PLA and ABS filament together ?
I have done assembly with to two parts. The parts are two separate ones that fit on top of each other and fit together. I know that PLA and ABS do not stick together. It is noted in these parts. the slicing (bambulab studio) does not allow progress because the temperature differences are too great.
why does the nozzle get blocked when it is fluhsed pla/abs and abs/pla. this happens at a temperature of 250. Production temperature has no effect on clogging.
quite simple…if you mix PLA and ABS and it changes from ABS to PLA then the nozzle might be too cold to flush the rest of the ABS out of the nozzle…so it can clog
If you change from PLA to ABS the nozzle is so hot that the too hot pla drops like goo out of the nozzle during filament change.
Depending on the Filaments there is a 60-70° temp difference in the extrusion temps…and…even while the hotend gets hot fast due the ceramic heater it takes much longer to cool down the 60°
yes its possible to print abs on low temp and the PLA on high temp…but then the part will just be structural bad because both filaments are printed out of their optimal print temp. And the shrinkage on both materials are not the same…more problems
and beside the clogging or oozing problem theres another one…if the fit is tight they will be conected mechanically due the overlapping of the layers…if you constructed a wide fit, there´s a gap that is not really good printable.
Let’s zoom out: why do you want to print these two materials together in this way in this case? Is there a functional driver, or you happen to have both materials and they’re different colors, or?
Both parts are the same color. I need better durability in that particular part of the handle. I can’t print the TPU at that point. but apparently not ABS either. Of course I could print the whole handle in ABS.
Of course I could build a joint from two separate prints. It just seems stupid to spend time on the construction if the printing was done by exchanging filaments.
I imagined that I could make multi-material prints with bambulab x1c than four different colors.
You’re going to get better mechanical properties aligning loads through components in the XY plane since printed parts have anisotropic strength (weaker to shear, bending, and tension in Z) so it makes sense to design for assembly if you really need them to be different materials.
I use the multi-material printing capability all the time to take advantage of the fact that dissimilar polymers don’t bond well—I use PETG as a support interface on PLA prints and vice-versa often.
If I’m going to try to combine materials in the way you’re thinking though I’m going to design for assembly or mechanical anchoring rather than depending on the inter-material bond (because that’s going to be very weak).
This isn’t a knock against the X1C here that it can’t, it’s just a reality of plastics. To get dissimilar plastics to bond even in traditional manufacturing is an art.
ABS printing temperature is 240-280. PLA printing temperature is 190-240. PLA fluhsed is temperature 250. ABS would be fluhsed at the same temperature. Even if I calculate abs temperatures closer to PLA, I can’t get Slicing done. ABS manages to print 235
even if you change the temperatures to the same for PLA and ABS, I can’t get the slicing done. same error.
Just create a custom profile for the filament and set the temperatures however you want. The default profiles are intended as starting points. Tweaking them to achieve your particular objectives is normal/expected.
Indeed. when I removed the AMS tags from the filament spool. and I said that AMS is two PLA coils with different colors and different temperature values. then the slicing was successful and the printing was successful without any problems.
Hi I met the same problem. I have set the ABS as a fake PLA. The slide worked. But the filament didn’t pull out correctly. what is your temp setting for both fliament? Thank you so much!
I experimented with using PLA as a support material for PETG because they do not stick to each other. However, every time to tried it, regardless of settings tweaks, it would fail after 5 +/- filament transitions with the nozzle clogged. I finally gave up.
Glad you got this to work, but my (admittedly limited) experience with using very different filaments is that the approaches discussed in this thread are not “sustainable” - i.e. it won’t work if there are a lot of filament transitions. If someone has made this work, I’d love to hear about it.
I picked this from a site. HIPS
Anyone experience with this kind of support ?
When it comes to comparing HIPS vs PVA (polyvinyl alcohol) as soluble support materials, it quickly becomes apparent that the two are apples and oranges. The lower printing temperature of PVA works means that it will work much better with a material like PLA while, as we’ve discussed, HIPS dissolvable filament and ABS are more suited to each other.
Both are equally soluble, PLA in water and HIPS in Limonene, so the only reason to pick one over the other as a support material comes down to what printing material you are using for your job.
HIPS prints best at a temperature between 230°C and 240°C
